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?

Galen, the physician

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.

  • What’s the difference between vegan and vegetarian?

    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.

    What’s the difference? is a new editorial product that explains the similarities and differences between commonly confused health and medical terms, and why they matter.

    Vegan and vegetarian diets are plant-based diets. Both include plant foods, such as fruits, vegetables, legumes and whole grains.

    But there are important differences, and knowing what you can and can’t eat when it comes to a vegan and vegetarian diet can be confusing.

    So, what’s the main difference?

    What’s a vegan diet?

    A vegan diet is an entirely plant-based diet. It doesn’t include any meat and animal products. So, no meat, poultry, fish, seafood, eggs, dairy or honey.

    What’s a vegetarian diet?

    A vegetarian diet is a plant-based diet that generally excludes meat, poultry, fish and seafood, but can include animal products. So, unlike a vegan diet, a vegetarian diet can include eggs, dairy and honey.

    But you may be wondering why you’ve heard of vegetarians who eat fish, vegetarians who don’t eat eggs, vegetarians who don’t eat dairy, and even vegetarians who eat some meat. Well, it’s because there are variations on a vegetarian diet:

    • a lacto-ovo vegetarian diet excludes meat, poultry, fish and seafood, but includes eggs, dairy and honey
    • an ovo-vegetarian diet excludes meat, poultry, fish, seafood and dairy, but includes eggs and honey
    • a lacto-vegetarian diet excludes meat, poultry, fish, seafood and eggs, but includes dairy and honey
    • a pescatarian diet excludes meat and poultry, but includes eggs, dairy, honey, fish and seafood
    • a flexitarian, or semi-vegetarian diet, includes eggs, dairy and honey and may include small amounts of meat, poultry, fish and seafood.

    Are these diets healthy?

    A 2023 review looked at the health effects of vegetarian and vegan diets from two types of study.

    Observational studies followed people over the years to see how their diets were linked to their health. In these studies, eating a vegetarian diet was associated with a lower risk of developing cardiovascular disease (such as heart disease or a stroke), diabetes, hypertension (high blood pressure), dementia and cancer.

    For example, in a study of 44,561 participants, the risk of heart disease was 32% lower in vegetarians than non-vegetarians after an average follow-up of nearly 12 years.

    Further evidence came from randomised controlled trials. These instruct study participants to eat a specific diet for a specific period of time and monitor their health throughout. These studies showed eating a vegetarian or vegan diet led to reductions in weight, blood pressure, and levels of unhealthy cholesterol.

    For example, one analysis combined data from seven randomised controlled trials. This so-called meta-analysis included data from 311 participants. It showed eating a vegetarian diet was associated with a systolic blood pressure (the first number in your blood pressure reading) an average 5 mmHg lower compared with non-vegetarian diets.

    It seems vegetarian diets are more likely to be healthier, across a number of measures.

    For example, a 2022 meta-analysis combined the results of several observational studies. It concluded a vegetarian diet, rather than vegan diet, was recommended to prevent heart disease.

    There is also evidence vegans are more likely to have bone fractures than vegetarians. This could be partly due to a lower body-mass index and a lower intake of nutrients such as calcium, vitamin D and protein.

    But it can be about more than just food

    Many vegans, where possible, do not use products that directly or indirectly involve using animals.

    So vegans would not wear leather, wool or silk clothing, for example. And they would not use soaps or candles made from beeswax, or use products tested on animals.

    The motivation for following a vegan or vegetarian diet can vary from person to person. Common motivations include health, environmental, ethical, religious or economic reasons.

    And for many people who follow a vegan or vegetarian diet, this forms a central part of their identity.

    More than a diet: veganism can form part of someone’s identity. Shutterstock

    So, should I adopt a vegan or vegetarian diet?

    If you are thinking about a vegan or vegetarian diet, here are some things to consider:

    • eating more plant foods does not automatically mean you are eating a healthier diet. Hot chips, biscuits and soft drinks can all be vegan or vegetarian foods. And many plant-based alternatives, such as plant-based sausages, can be high in added salt
    • meeting the nutrient intake targets for vitamin B12, iron, calcium, and iodine requires more careful planning while on a vegan or vegetarian diet. This is because meat, seafood and animal products are good sources of these vitamins and minerals
    • eating a plant-based diet doesn’t necessarily mean excluding all meat and animal products. A healthy flexitarian diet prioritises eating more whole plant-foods, such as vegetables and beans, and less processed meat, such as bacon and sausages
    • the Australian Dietary Guidelines recommend eating a wide variety of foods from the five food groups (fruit, vegetables, cereals, lean meat and/or their alternatives and reduced-fat dairy products and/or their alternatives). So if you are eating animal products, choose lean, reduced-fat meats and dairy products and limit processed meats.

  • Tilapia vs Cod – 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 tilapia to cod, we picked the tilapia.

    Why?

    Another case of “that which is more expensive is not necessarily the healthier”!

    In terms of macros, tilapia has more protein and fats, as well as more omega-3 (and omega-6). On the downside, tilapia does have relatively more saturated fat, but at 0.94g/100g, it’s not exactly butter.

    The vitamins category sees that tilapia has more of vitamins B1, B3, B5, B12, D, and K, while cod has more of vitamins B6, B9, and choline. A moderate win for tilapia.

    When it comes to minerals, things are most divided; tilapia has more copper, iron, phosphorus, potassium, manganese, and selenium, while cod has more magnesium and zinc. An easy win for tilapia.

    One other thing to note is that both of these fish contain mercury these days (and it’s worth noting: cod has nearly 10x more mercury). Mercury is, of course, not exactly a health food.

    So, excessive consumption of either is not recommended, but out of the two, tilapia is definitely the one to pick.

  • 14 Powerful Strategies To Prevent Dementia

    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.

    Dementia risk starts climbing very steeply after the age of 65, but it’s not entirely predetermined. Dr. Brad Stanfield, a primary care physician, has insights:

    The strategies

    We’ll not keep them a mystery; they are:

    • Cognitive stimulation: which means genuinely challenging mental activities using a variety of mental faculties. This will usually mean that anything that is just “same old, same old” all the time will stop giving benefits after a short while once it becomes rote, and you’ll need something harder and/or different.
    • Hearing health: being unable to participate in conversations increases dementia risk; hearing aids can help.
    • Eyesight health: similar to the above; regular eye tests are good, and the use of glasses where appropriate.
    • Depression management: midlife depression is linked to later life dementia, likely in large part due to social isolation and a lack of stimulation, but either way, treating depression earlier reduces later dementia risk.
    • Exercising regularly: what’s good for the heart is good for the brain; the brain is a hungry organ and the blood is what feeds it (and removes things that shouldn’t be there)
    • Head injury avoidance: even mild head injuries can cause problems down the road. Protecting one’s head in sports, and even while casually cycling, is important.
    • Smoking cessation: just don’t smoke; if you smoke, make it a top priority to quit unless you are given direct strong medical advice to the contrary (there are cases, few and far between, whereby quitting smoking genuinely needs to be deferred until after something else is dealt with first, but they are a lot rarer than a lot of people who are simply afraid of quitting would like to believe)
    • Cholesterol management: again, healthy blood means a healthy brain, and that goes for triglycerides too.
    • Weight management: obesity, especially waist to hip ratio (indicating visceral abdominal fat specifically) is associated with many woes, including dementia.
    • Diabetes management: once again, healthy blood means a healthy brain, and that goes for blood sugar management too.
    • Blood pressure management: guess what, healthy blood still means a healthy brain, and that goes for blood pressure too.
    • Alcohol reduction/cessation: alcohol is bad for pretty much everything, and for most people who drink, quitting is probably the top thing to do after quitting smoking.
    • Social engagement: while we all may have our different preferences on a scale of introversion to extroversion, we are fundamentally a social species and thrive best with social contact, even if it’s just a few people.
    • Air pollution reduction: avoiding pollutants, and filtering the air we breathe where pollutants are otherwise unavoidable, makes a measurable difference to brain health outcomes.

  • Beat Osteoporosis with Exercise – by Dr. Karl Knopf

    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.

    There are a lot of books about beating osteoporosis, and yet when it comes to osteoporosis exercises, it took us some work to find a good one. But, this one’s it!

    A lot of books give general principles and a few sample exercises. This one, in contrast, gives:

    • An overview of osteopenia and osteoporosis, first
    • A brief overview of non-exercise osteoporosis considerations
    • Principles for exercising a) to reduce one’s risk of osteoporosis b) if one has osteoporosis
    • Clear explanations of about 150 exercises that fit both categories

    This last item’s important, because a lot of popular advice is exercises that are only good for one or the other (given that a lot of things that strengthen a healthy person’s bones can break the bones of someone with osteoporosis), so having 150 exercises that are safe and effective in both cases, is a real boon.

    That doesn’t mean you have to do all 150! If you want to, great. But even just picking and choosing and putting together a little program is good.

    Bottom line: if you’d like a comprehensive guide to exercise to keep you strong in the face of osteoporosis, this is a great one.

  • Health & Happiness From Outside & In

    A friend in need…

    In a recent large (n=3,486) poll across the US:

    • 90% of people aged 50 and older say they have at least one close friend
    • 75% say they have enough close friends
    • 70% of those with a close friend say they can definitely count on them to provide health-related support

    However, those numbers shrink by half when it comes to people whose physical and/or mental health is not so great, resulting in a negative feedback loop of fewer close friends whom one sees less often, and progressively worse physical and/or mental health. In other words, the healthier you are, the more likely you are to have a friend who’ll support you in your health:

    Kindness makes a difference to healthcare outcomes

    Defining kindness as action-oriented, positively focused, and purposeful in nature, this sets kindness apart from compassion and empathy, when it’s otherwise often been conflated with those, and thus overlooked. This also means that kindness can still be effected when clinicians are too burned-out to be compassionate, and/or when patients are not in a state of mind where empathy is useful.

    Furthermore, unkindness (again, as defined by this review) was found in large studies to be the root cause of ¾ of patient harm events in hospital settings. This means that far from being a wishy-washy abstraction, kindness/unkindness can be a very serious factor when it comes to healthcare outcomes:

    The gift of health?

    🎵 Last Christmas, I gave you my heart
    Which turned out to be a silly idea
    This year, to save me from tears
    I’ll just get you a Fitbit or something🎵

    Health & happiness go hand in hand, so does that make health stuff a good gift? It can do! But there are also plenty of opportunities for misfires.

    For example, getting someone a gym membership when they don’t have time for that may not help them at all, and sports equipment that they’ll use once and then leave to gather dust might not be great either. In contrast, the American Heart Association recommends to first consider what they enjoy doing, and work with that, and ideally make it something versatile and/or portable. Wearable gadgets are a fine option for many, but a gift doesn’t have to be fancy to be good—with a blood pressure monitoring cuff being a suggestion from Dr. Sperling (a professor of preventative cardiology):

    How you use social media matters more than how much

    A study commissioned by the European Commission’s Joint Research Centre found that while the quantity of time one spends on social media is not associated (positively or negatively) with loneliness, they did find a correlation between passive (as opposed to engaged) use of social media, and loneliness. In other words, people who were chatting with friends less, were more lonely! Shocking news.

    While the findings may seem obvious, it does present a call-to-action for anyone who is feeling lonely: to use social media not just to see what everyone else is up to, but also, to reach out to people.

    Gut-only antidepressants

    Many antidepressants work by increasing serotonin levels in the brain; a new study suggests that targeting antidepressants to work only in the gut (which is where serotonin is made, not the brain) could not only be an effective treatment for mood disorders, but also cause fewer adverse side-effects:

  • Women Rowing North – by Dr. Mary Pipher

    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.

    Ageism is rife, as is misogyny. And those can be internalized too, and compounded as they intersect.

    Clinical psychologist Dr. Mary Pipher, herself 75, writes for us a guidebook of, as the subtitle goes, “navigating life’s currents and flourishing as we age”.

    The book does assume, by the way, that the reader is…

    • a woman, and
    • getting old (if not already old)

    However, the lessons the book imparts are vital for women of any age, and valuable as a matter of insight and perspective for any reader.

    Dr. Pipher takes us on a tour of aging as a woman, and what parts of it we can make our own, do things our way, and take what joy we can from it.

    Nor is the book given to “toxic positivity” though—it also deals with themes of hardship, frustration, and loss.

    When it comes to those elements, the book is… honest, human, and raw. But also, an exhortation to hope, beauty, and a carpe diem attitude.

    Bottom line: this book is highly recommendable to anyone of any age; life is precious and can be short. And be we blessed with many long years, this book serves as a guide to making each one of them count.
