Why is cancer called cancer? We need to go back to Greco-Roman times for the answer

One of the earliest descriptions of someone with cancer comes from the fourth century BC. Satyrus, tyrant of the city of Heracleia on the Black Sea, developed a cancer between his groin and scrotum. As the cancer spread, Satyrus had ever greater pains. He was unable to sleep and had convulsions.

Advanced cancers in that part of the body were regarded as inoperable, and there were no drugs strong enough to alleviate the agony. So doctors could do nothing. Eventually, the cancer took Satyrus’ life at the age of 65.

Cancer was already well known in this period. A text written in the late fifth or early fourth century BC, called Diseases of Women, described how breast cancer develops:

hard growths form […] out of them hidden cancers develop […] pains shoot up from the patients’ breasts to their throats, and around their shoulder blades […] such patients become thin through their whole body […] breathing decreases, the sense of smell is lost […]

Other medical works of this period describe different sorts of cancers. A woman from the Greek city of Abdera died from a cancer of the chest; a man with throat cancer survived after his doctor burned away the tumour.

Where does the word ‘cancer’ come from?

The word cancer comes from the same era. In the late fifth and early fourth century BC, doctors were using the word karkinos – the ancient Greek word for crab – to describe malignant tumours. Later, when Latin-speaking doctors described the same disease, they used the Latin word for crab: cancer. So, the name stuck.

Even in ancient times, people wondered why doctors named the disease after an animal. One explanation was the crab is an aggressive animal, just as cancer can be an aggressive disease; another explanation was the crab can grip one part of a person’s body with its claws and be difficult to remove, just as cancer can be difficult to remove once it has developed. Others thought it was because of the appearance of the tumour.

The physician Galen (129-216 AD) described breast cancer in his work A Method of Medicine to Glaucon, and compared the form of the tumour to the form of a crab:

We have often seen in the breasts a tumour exactly like a crab. Just as that animal has feet on either side of its body, so too in this disease the veins of the unnatural swelling are stretched out on either side, creating a form similar to a crab.

Not everyone agreed what caused cancer

In the Greco-Roman period, there were different opinions about the cause of cancer.

According to a widespread ancient medical theory, the body has four humours: blood, yellow bile, phlegm and black bile. These four humours need to be kept in a state of balance, otherwise a person becomes sick. If a person suffered from an excess of black bile, it was thought this would eventually lead to cancer.

The physician Erasistratus, who lived from around 315 to 240 BC, disagreed. However, so far as we know, he did not offer an alternative explanation.

How was cancer treated?

Cancer was treated in a range of different ways. It was thought that cancers in their early stages could be cured using medications.

These included drugs derived from plants (such as cucumber, narcissus bulb, castor bean, bitter vetch, cabbage); animals (such as the ash of a crab); and metals (such as arsenic).

Galen claimed that by using this sort of medication, and repeatedly purging his patients with emetics or enemas, he was sometimes successful at making emerging cancers disappear. He said the same treatment sometimes prevented more advanced cancers from continuing to grow. However, he also said surgery is necessary if these medications do not work.

Surgery was usually avoided as patients tended to die from blood loss. The most successful operations were on cancers of the tip of the breast. Leonidas, a physician who lived in the second and third century AD, described his method, which involved cauterising (burning):

I usually operate in cases where the tumours do not extend into the chest […] When the patient has been placed on her back, I incise the healthy area of the breast above the tumour and then cauterize the incision until scabs form and the bleeding is stanched. Then I incise again, marking out the area as I cut deeply into the breast, and again I cauterize. I do this [incising and cauterizing] quite often […] This way the bleeding is not dangerous. After the excision is complete I again cauterize the entire area until it is dessicated.

Cancer was generally regarded as an incurable disease, and so it was feared. Some people with cancer, such as the poet Silius Italicus (26-102 AD), died by suicide to end the torment.

Patients would also pray to the gods for hope of a cure. An example of this is Innocentia, an aristocratic lady who lived in Carthage (in modern-day Tunisia) in the fifth century AD. She told her doctor divine intervention had cured her breast cancer, though her doctor did not believe her.

From the past into the future

We began with Satyrus, a tyrant in the fourth century BC. In the 2,400 years or so since then, much has changed in our knowledge of what causes cancer, how to prevent it and how to treat it. We also know there are more than 200 different types of cancer. Some people’s cancers are so successfully managed, they go on to live long lives.

But there is still no general “cure for cancer”, a disease that about one in five people develop in their lifetime. In 2022 alone, there were about 20 million new cancer cases and 9.7 million cancer deaths globally. We clearly have a long way to go.

  • How long does back pain last? And how can learning about pain increase the chance of recovery?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Back pain is common. One in thirteen people have it right now and worldwide a staggering 619 million people will have it this year.

    Chronic pain, of which back pain is the most common, is the world’s most disabling health problem. Its economic impact dwarfs other health conditions.

    If you get back pain, how long will it take to go away? We scoured the scientific literature to find out. We found data on almost 20,000 people, from 95 different studies and split them into three groups:

    • acute – those with back pain that started less than six weeks ago
    • subacute – where it started between six and 12 weeks ago
    • chronic – where it started between three months and one year ago.

    We found 70%–95% of people with acute back pain were likely to recover within six months. This dropped to 40%–70% for subacute back pain and to 12%–16% for chronic back pain.

    Clinical guidelines point to graded return to activity and pain education under the guidance of a health professional as the best ways to promote recovery. Yet these effective interventions are underfunded and hard to access.

    More pain doesn’t mean a more serious injury

    Most acute back pain episodes are not caused by serious injury or disease.

    There are rare exceptions, which is why it’s wise to see your doctor or physio, who can check for signs and symptoms that warrant further investigation. But unless you have been in a significant accident or sustained a large blow, you are unlikely to have caused much damage to your spine.

    Even very minor back injuries can be brutally painful. This is, in part, because of how we are made. If you think of your spinal cord as a very precious asset (which it is), worthy of great protection (which it is), a bit like the crown jewels, then what would be the best way to keep it safe? Lots of protection and a highly sensitive alarm system.

    The spinal cord is protected by strong bones, thick ligaments, powerful muscles and a highly effective alarm system (your nervous system). This alarm system can trigger pain that is so unpleasant that you cannot possibly think of, let alone do, anything other than seek care or avoid movement.

    The messy truth is that when pain persists, the pain system becomes more sensitive, so a widening array of things contribute to pain. This pain system hypersensitivity is a result of neuroplasticity – your nervous system is becoming better at making pain.

    Reduce your chance of lasting pain

    Whether or not your pain resolves is not determined by the extent of injury to your back. We don’t know all the factors involved, but we do know there are things that you can do to reduce chronic back pain:

    • understand how pain really works. This will involve intentionally learning about modern pain science and care. It will be difficult but rewarding. It will help you work out what you can do to change your pain
    • reduce your pain system sensitivity. With guidance, patience and persistence, you can learn how to gradually retrain your pain system back towards normal.

    How to reduce your pain sensitivity and learn about pain

    Learning about “how pain works” provides the most sustainable improvements in chronic back pain. Programs that combine pain education with graded brain and body exercises (gradual increases in movement) can reduce pain system sensitivity and help you return to the life you want.

    Some programs combine education with gradual increases in movement.

    These programs have been in development for years, but high-quality clinical trials are now emerging and it’s good news: they show most people with chronic back pain improve and many completely recover.

    But most clinicians aren’t equipped to deliver these effective programs – good pain education is not taught in most medical and health training degrees. Many patients still receive ineffective and often risky and expensive treatments, or keep seeking temporary pain relief, hoping for a cure.

    When health professionals don’t have adequate pain education training, they can deliver bad pain education, which leaves patients feeling like they’ve just been told it’s all in their head.

    Community-driven not-for-profit organisations such as Pain Revolution are training health professionals to be good pain educators and raising awareness among the general public about the modern science of pain and the best treatments. Pain Revolution has partnered with dozens of health services and community agencies to train more than 80 local pain educators and supported them to bring greater understanding and improved care to their colleagues and community.

    But a broader system-wide approach, with government, industry and philanthropic support, is needed to expand these programs and fund good pain education. To solve the massive problem of chronic back pain, effective interventions need to be part of standard care, not as a last resort after years of increasing pain, suffering and disability.The Conversation

    In order to provide variety in this week’s round-up, not all of this is menopause-related, but it is all important:

    Menopause & CVD

    Untreated menopause is associated with higher incidence of heart disease, and higher mortality. People often forget about how much estrogen does for us (well, for those of us with a physiology running on estrogen, anyway; gentlemen, your testosterone is fine for you), and think it is “just” a sex hormone, but it’s a lot more.

    Extraterrestrial medical technology

    The much lower gravity in Earth orbit has allowed for tissue engineering techniques that Earth’s normal gravity imposes limitations on. This is big news, because it means that rather than replacing a whole liver, tissue implants could be grafted, allowing the extant liver to repair itself (something livers are famously good at, but they need enough undamaged base material to work with).

    One thing and then another

    As if endometriosis weren’t unpleasant enough in and of itself, the endothelial dysfunction inherent to it also raises cardiovascular disease risk. This is important, because while endometriosis has (like many maladies predominantly affecting women) generally been shrugged off by the medical world as an unhappy inconvenience but not life-threatening, now we know it comes with extra existential risks too:

    Push-button meditation

    Unlike mindfulness meditation, listening to music is a very passive experience, and thus requires less effort from the user. And yet, it has been associated with lower perceived pain levels, lower self-reported anxiety levels, less opioid use, and measurably lower heart-rate.

    Cholesterol in menopause: quality over quantity

    Much like previous research has shown that the quantity of LDL is not nearly so predictive of health outcomes in women as it is in men, this study into HDL and menopausal women shows that quantity of HDL does not matter nearly so much as the quality of it.

    Read in full: HDL quality, not quantity, contribute to the first sign of Alzheimer’s disease in women

    Related: Statins: His & Hers? ← consistent with the above, statins (to lower LDL cholesterol) generally help more for men and produce more adverse side effects for women. So again, a case of “the actual amount of cholesterol isn’t so important for women as for men”.

  • Apple Cider Vinegar vs Apple Cider Vinegar Gummies – Which is Healthier?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our Verdict

    When comparing apple cider vinegar (bottled) to apple cider vinegar (gummies), we picked the bottled.

    Why?

    There are several reasons!

    The first reason is about dosage. For example, the sample we picked for apple cider vinegar gummies, boasts:

    2 daily chewable gummies deliver 800 mg of Apple Cider Vinegar a day, equivalent to a teaspoon of liquid apple cider vinegar

    That sounds good until you note that it’s recommended to take 1–2 tablespoons (not teaspoons) of apple vinegar. So this would need more like 4–8 gummies to make the dose. Suddenly, either that bottle of gummies is running out quickly, or you’re just not taking a meaningful dose and your benefits will likely not exceed placebo.

    The other is reason about sugar. Most apple cider vinegar gummies are made with some kind of sugar syrup, often even high-fructose corn syrup, which is one of the least healthy foodstuffs (in the loosest sense of the word “foodstuffs”) known to science.

    The specific brand we picked today was the best we can find; it used maltitol syrup.

    Maltitol syrup, a corn derivative (and technically a sugar alcohol), has a Glycemic Index of 52, so it does raise blood sugars but not as much as sucrose would. However (and somewhat counterproductive to taking apple cider vinegar for gut health) it can cause digestive problems for many people.

    And remember, you’re taking 4–8 gummies, so this is amounting to several tablespoons of the syrup by now.

    On the flipside, apple cider vinegar itself has two main drawbacks, but they’re much less troublesome issues:

    • many people don’t like the taste
    • its acidic nature is not good for teeth

    To this the common advice for both is to dilute it with water, thus diluting the taste and the acidity.

    (this writer shoots hers from a shot glass, thus not bathing the teeth since it passes them “without touching the sides”; as for the taste, well, I find it invigorating—I do chase it with water, though to be sure of not leaving vinegar in my mouth)

  • Sizing Aside: Are You Wearing The Right Bra For Your Breast Shape?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    It’s well-known that most women wear incorrectly-fitting bras. Even with careful measurements, buying “off-the-rack” can be a challenge, because the sizing system only takes two measurements, when there are actually many more things to consider. Today’s video demystifies a lot of what else is going on!

    For example…

    Some of the different breast shapes/arrangements to consider:

    • Wide-set breasts: likely to find there’s a bit of a gap between your breasts and the inside (nearest to your sternum) parts of the cups—while spilling out a little at the outside edges. The solution? Bras that offer side-support, to keep things pointing more forwards. Central-closing bras can also help gather things together, and a balconette bra can redistribute things more evenly. Any of these options will be a lot more comfortable.
    • Small breasts: bralettes are your friend, keeping things comfortable while not wearing more bra than necessary to do the job (of course going braless is also an option, but we’re talking bra-fitting here, not bra-flinging-off never to be seen again)
    • Deflated breasts: often the case for someone who used to have larger breasts, but they lost size for hormonal reasons rather than for weight loss reasons. This often occurs a little while after childbirth, and also happens a lot in menopause. The bra recommendation for this? A push-up plunge bra with ¾ coverage not only provides cleavage if that’s wanted, but also, will keep things much more snug and thus more evenly-distributed. If ever you’ve found yourself needing to adjust yourself every now and gain while out, this will fix that and keep you comfortable for much longer.

  • The Procrastination Cure – by Jeffery Combs

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Why do we procrastinate? It’s not usually because we are lazy, and in fact we can often make ourselves very busy while procrastinating. And at some point, the bad feelings about procrastinating become worse than the experience of actually doing the thing. And still we often procrastinate. So, why?

    Jeffery Combs notes that the reasons can vary, but generally fall into six mostly-distinct categories. He calls them:

    1. The neurotic perfectionist
    2. The big deal chaser
    3. The chronic worrier
    4. The rebellious rebel
    5. The drama addict
    6. The angry giver

    These may overlap somewhat, but the differences are important when it comes to differences of tackling them.

    Giving many illustrative examples, Combs gives the reader all we’ll need to know which category (or categories!) we fall into.

    Then, he draws heavily on the work of Dr. Albert Ellis to find ways to change the feelings that we have that are holding us back.

    Those feelings might be fear, shame, resentment, overwhelm, or something else entirely, but the tools are in this book.

    A particular strength of this book is that it takes an approach that’s essentially Rational Emotive Behavior Therapy (REBT) repackaged for a less clinically-inclined audience (Combs’ own background is in marketing, not pyschology). Thus, for many readers, this will tend to make the ideas more relatable, and the implementations more accessible.

    Bottom line: if you’ve been meaning to figure out how to beat your procrastination, but have been putting it off, now’s the time to do it.

  • ‘Free birthing’ and planned home births might sound similar but the risks are very different

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    The death of premature twins in Byron Bay in an apparent “wild birth”, or free birth, last week has prompted fresh concerns about giving birth without a midwife or medical assistance.

    This follows another case from Victoria this year, where a baby was born in a critical condition following a reported free birth.

    It’s unclear how common free birthing is, as data is not collected, but there is some evidence free births increased during the COVID pandemic.

    Planned home births also became more popular during the pandemic, as women preferred to stay away from hospitals and wanted their support people with them.

    But while free births and home births might sound similar, they are a very different practice, with free births much riskier. So what’s the difference, and why might people opt for a free birth?

    What are home births?

    Planned home births involve care from midwives, who are registered experts in childbirth, in a woman’s home.

    These registered midwives work privately, or are part of around 20 publicly funded home birth programs nationally that are attached to hospitals.

    They provide care during the pregnancy, labour and birth, and in the first six weeks following the birth.

    The research shows that for women with low risk pregnancies, planned home births attended by competent midwives (with links to a responsive mainstream maternity system) are safe.

    Home births result in less intervention than hospital births and women perceive their experience more positively.

    What are free births?

    A free birth is when a woman chooses to have a baby, usually at home, without a registered health professional such as a midwife or doctor in attendance.

    Different terms such as unassisted birth or wild pregnancy or birth are also used to refer to free birth.

    The parents may hire an unregulated birth worker or doula to be a support at the birth but they do not have the training or medical equipment needed to manage emergencies.

    Women may have limited or no health care antenatally, meaning risk factors such as twins and breech presentations (the baby coming bottom first) are not detected beforehand and given the right kind of specialist care.

    Why do some people choose to free birth?

    We have been studying the reasons women and their partners choose to free birth for more than a decade. We found a previous traumatic birth and/or feeling coerced into choices that are not what the woman wants were the main drivers for avoiding mainstream maternity care.

    Australia’s childbirth intervention rates – for induction or augmentation of labour, episiotomy (cutting the tissue between the vaginal opening and the anus) and caesarean section – are comparatively high.

    One in ten women report disrespectful or abusive care in childbirth and some decide to make different choices for future births.

    Lack of options for a natural birth and birth choices such as home birth or birth centre birth also played a major role in women’s decision to free birth.

    Publicly funded home birth programs have very strict criteria around who can be accepted into the program, excluding many women.

    In other countries such as the United Kingdom, Netherlands and New Zealand, publicly funded home births are easier to access.

    Only around 200 midwives provide private midwifery services for home births nationally. Private midwives are yet to obtain insurance for home births, which means they are risking their livelihoods if something goes wrong and they are sued.

    The cost of a home birth with a private midwife is not covered by Medicare and only some health funds rebate some of the cost. This means women can be out of pocket A$6-8,000.

    Access to home birth is an even greater issue in rural and remote Australia.

    How to make mainstream care more inclusive

    Many women feel constrained by their birth choices in Australia. After years of research and listening to thousands of women, it’s clear more can be done to reduce the desire to free birth.

    As my co-authors and I outline in our book, Birthing Outside the System: The Canary in the Coal Mine, this can be achieved by:

    • making respectful care a reality so women aren’t traumatised and alienated by maternity care and want to engage with it
    • supporting midwifery care. Women are seeking more physiological and social ways of birthing, minimising birth interventions, and midwives are the experts in this space
    • supporting women’s access to their chosen place of birth and model of care and not limiting choice with high out-of-pocket expenses
    • providing more flexible, acceptable options for women experiencing risk factors during pregnancy and/or birth, such as having a previous caesarean birth, having twins or having a baby in breech position. Women experiencing these complications experience pressure to have a caesarean section
    • getting the framework right with policies, guidelines, education, research, regulation and professional leadership.

    Ensuring women’s rights and choices are informed and respected means they’re less likely to feel they’re left with no other option.The Conversation
