If I’m diagnosed with one cancer, am I likely to get another?

Receiving a cancer diagnosis is life-changing and can cause a range of concerns about ongoing health.
Fear of cancer returning is one of the top health concerns. And managing this fear is an important part of cancer treatment.
But how likely is it to get cancer for a second time?
Why can cancer return?
While initial cancer treatment may seem successful, sometimes a few cancer cells remain dormant. Over time, these cancer cells can grow again and may start to cause symptoms.
This is known as cancer recurrence: when a cancer returns after a period of remission. This period could be days, months or even years. The new cancer is the same type as the original cancer, but can sometimes grow in a new location through a process called metastasis.
Actor Hugh Jackman has gone public about his multiple diagnoses of basal cell carcinoma (a type of skin cancer) over the past decade.
The exact reason why cancer returns differs depending on the cancer type and the treatment received. Research is ongoing to identify genes associated with cancers returning. This may eventually allow doctors to tailor treatments for high-risk people.
What are the chances of cancer returning?
The risk of cancer returning differs between cancers, and between sub-types of the same cancer.
New screening and treatment options have seen reductions in recurrence rates for many types of cancer. For example, between 2004 and 2019, the risk of colon cancer recurring dropped by 31-68%. It is important to remember that only someone’s treatment team can assess an individual’s personal risk of cancer returning.
For most types of cancer, the highest risk of cancer returning is within the first three years after entering remission. This is because any leftover cancer cells not killed by treatment are likely to start growing again sooner rather than later. Three years after entering remission, recurrence rates for most cancers decrease, meaning that every day that passes lowers the risk of the cancer returning.
Every day that passes also increases the numbers of new discoveries, and cancer drugs being developed.
What about second, unrelated cancers?
Earlier this year, we learned Sarah Ferguson, Duchess of York, had been diagnosed with malignant melanoma (a type of skin cancer) shortly after being treated for breast cancer.
Although details have not been confirmed, this is likely a new cancer that isn’t a recurrence or metastasis of the first one.
Australian research from Queensland and Tasmania shows adults who have had cancer have around a 6-36% higher risk of developing a second primary cancer compared to the risk of cancer in the general population.
Who’s at risk of another, unrelated cancer?
With improvements in cancer diagnosis and treatment, people diagnosed with cancer are living longer than ever. This means they need to consider their long-term health, including their risk of developing another unrelated cancer.
Reasons for such cancers include different types of cancers sharing the same kind of lifestyle, environmental and genetic risk factors.
The increased risk is also likely partly due to the effects that some cancer treatments and imaging procedures have on the body. However, this increased risk is relatively small when compared with the (sometimes lifesaving) benefits of these treatment and procedures.
While a 6-36% greater chance of getting a second, unrelated cancer may seem large, only around 10-12% of participants developed a second cancer in the Australian studies we mentioned. Both had a median follow-up time of around five years.
Similarly, in a large US study only about one in 12 adult cancer patients developed a second type of cancer in the follow-up period (an average of seven years).
The kind of first cancer you had also affects your risk of a second, unrelated cancer, as well as the type of second cancer you are at risk of. For example, in the two Australian studies we mentioned, the risk of a second cancer was greater for people with an initial diagnosis of head and neck cancer, or a haematological (blood) cancer.
People diagnosed with cancer as a child, adolescent or young adult also have a greater risk of a second, unrelated cancer.
What can I do to lower my risk?
Regular follow-up examinations can give peace of mind, and ensure any subsequent cancer is caught early, when there’s the best chance of successful treatment.
Maintenance therapy may be used to reduce the risk of some types of cancer returning. However, despite ongoing research, there are no specific treatments against cancer recurrence or developing a second, unrelated cancer.
But there are things you can do to help lower your general risk of cancer – not smoking, being physically active, eating well, maintaining a healthy body weight, limiting alcohol intake and being sun safe. These all reduce the chance of cancer returning and getting a second cancer.

Practical Optimism – by Dr. Sue Varma
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.
We’ve written before about how to get your brain onto a more positive track (without toxic positivity), but there’s a lot more to be said than we can fit into an article, so here’s a whole book packed full with usable advice.
The subtitle claims “the art, science, and practice of…”, but mostly it’s the science of. If there’s art to be found here, then this reviewer missed it, and as for the practice of, well, that’s down to the reader, of course.
However, it is easy to use the contents of this book to translate science into practice without difficulty.
If you’re a fan of acronyms, initialisms, and other mnemonics (such as the rhyming “Name, Claim, Tame, and Reframe”), then you’ll love this book as they come thick and fast throughout, and they contribute to the overall ease of application of the ideas within.
The writing style is conversational but with enough clinical content that one never forgets who is speaking—not in the egotistical way that some authors do, but rather, just, she has a lot of professional experience to share and it shows.
Bottom line: if you’d like to be more optimistic without delving into the delusional, this book can really help a lot with that (in measurable ways, no less!).

Saffron For The Brain (& More)
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.
Saffron For The Brain (& More)
In yesterday’s edition of 10almonds, one of the items in the “health news from around the world” section was:
Clinical trial finds herbal medicine Sailuotong effective for brain health in older people
But, what is it?
❝SaiLuoTong (SLT) is a modern compound Chinese herbal medicine preparation in capsule form containing standardized extracts of Panax ginseng, Ginkgo biloba, and Crocus sativus L❞
We’ve written previously about ginseng and ginkgo biloba:
So, what’s this about Crocus sativus L.?
That is the plant better known as saffron. And, for all its wide availability (your local supermarket probably has at least a tiny amount in the spice section), there’s a reason we don’t see much of it:
❝Saffron blooms only once a year and should be collected within a very short duration. It is picked during 3–4 weeks in October-November. The method for the cultivation of saffron contributes greatly to its high price. According to some reports, this species is a sterile triploid and so does not produce fertile seeds. Germination can take 1–6 months at 18°C. It takes 3 years for plants to flower from seed.❞
Source: Crocus sativus L.: A comprehensive review
That’s fascinating, but what does it do for us?
Well, in the words of El Midaoui et al. (2022):
❝In the frame of a double-blind-placebo-controlled study, 30 mg per day supplementation with saffron for 16 weeks resulted in improved cognitive function in patients suffering from mild to moderate Alzheimer’s disease.
Moreover, the follow-up of this study in which the authors evaluated the effects of saffron (30 mg/day) for 22 weeks showed that saffron was as effective as donepezil in the treatment of mild-to-moderate Alzheimer’s disease❞
Read the full review: Saffron (Crocus sativus L.): A Source of Nutrients for Health and for the Treatment of Neuropsychiatric and Age-Related Diseases
Not just that, but it also has powerful antioxidant and anti-inflammatory properties beyond the brain (though the brain is where research has been most focused, due to its neuroprotective effects).
(this, too, is a full research review in its own right; we’re getting a lot of “bang for buck” on papers today)
And more?
Yes, and more. Lots more. To bullet-pointify even just the abstract from another research review:
- Saffron has been suggested to be effective in the treatment of a wide range of disorders including coronary artery diseases, hypertension, stomach disorders, dysmenorrhea and learning and memory impairments.
- In addition, different studies have indicated that saffron has anti-inflammatory, anti-atherosclerotic, antigenotoxic and cytotoxic activities. (This is all good; the cytotoxic activities are about killing cancer cells)
- Antitussive effects of stigmas and petals of C. sativus and its components, safranal and crocin have also been demonstrated.
- The anticonvulsant and anti-Alzheimer properties of saffron extract were shown in human and animal studies.
- The efficacy of C. sativus in the treatment of mild to moderate depression was also reported in clinical trial.
- Administration of C. sativus and its constituents increased glutamate and dopamine levels in the brain in a dose-dependent manner.
- It also interacts with the opioid system to reduce withdrawal syndrome.
- C. sativus and its components can be considered as promising agents in the treatment of nervous system disorders.
For more details on any of those items, see:
The effects of Crocus sativus (saffron) and its constituents on nervous system: a review
Is it safe?
The effective dose is 30mg/kg and the LD50 is more than 20g/kg, so yes, it’s very safe. Given the price of it, this also means that if you’re the size of this writer (a little over 70kg, or a little over 150lbs) to poison yourself effectively you’d need to consume about 1.4kg of saffron at a time, which would cost well over $6,000.
Where can I get it?
Your local supermarket probably has a tiny amount in the spice section, or you can get better prices buying it in “bulk” online. Here’s an example product on Amazon, for your convenience
Enjoy!

3 Secrets Behind The Healing Power Of Plants
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-established that whole food plant-based diets including fruits, vegetables, beans, whole grains, nuts, and seeds can reverse chronic diseases like type 2 diabetes, hypertension, high cholesterol, obesity, and more.
Dr. Laurie Marbas explains how it works:
Three ways plant-based diets heal
There’s a lot to be said for plants, from their fiber to their beneficial phytochemicals. For example:
Reversing insulin resistance: plant-based diets help reverse insulin resistance, a major factor in type 2 diabetes, heart disease, obesity, and many other maladies. Particularly high-fiber foods like beans and oats stabilize blood sugar by slowing sugar absorption and reducing insulin spikes. These diets are also naturally low in saturated fats, which are linked to insulin resistance, and include phytonutrients from colorful fruits and vegetables that improve insulin sensitivity. Studies demonstrate that plant-based diets lower HbA1C levels (glycated hemoglobin, a measure of how sugary your blood has been on average in the past 2−3 months) and can even reverse type 2 diabetes for most* people.
*Scientists are very reluctant to claim absolutes such as “all”, “every”, etc, since it cannot be proven that it will work for all people (there are over 8 billion of us after all, and any one of us could get in theory get type 2 diabetes and then try reversing it, so it’s hard to speak for all 8 billion-odd of us) but it is well-established that it usually does indeed reverse it, and for what it’s worth, the confidence interval in such studies is always at least 95% sure, usually higher, which multiplied by countless studies can indeed give us quite some confidence.
Reducing chronic inflammation: chronic inflammation, linked to diseases like arthritis, heart disease, and cancer, can also be reduced through a plant-based diet. Foods rich in antioxidants, such as berries, leafy greens, and nuts, neutralize inflammation-causing free radicals. Omega-3-rich plant foods like chia seeds, flax seeds, and walnuts further balance inflammation. Additionally, fiber fosters healthy gut bacteria, which produce vital compounds that reduce systemic inflammation (and do a lot more good things besides, but we’re limiting ourselves to talking about inflammation here). Research shows that plant-based diets can significantly lower inflammation markers within weeks (almost certainly you’ll notice the difference yourself, too).
Synergy of whole foods: perhaps the biggest power of a plant-based diet lies in the synergy of its components. Nutrients like the fiber and phytonutrients we mentioned work together to combat inflammation and remove waste products that could fuel disease. For example, magnesium, found abundantly in leafy greens (which is why most Americans are deficient in magnesium), supports over 300 enzymatic processes, including blood sugar and inflammation regulation. This holistic approach ensures the whole body receives all the tools it needs to repair, regenerate, and thrive, thus once you’re on the right track, it’s “the gift that keeps on giving” when it comes to health, as each part helps the other parts to work better, which help the other parts to work better, which… (etc)

How Stress Affects Your Body
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.
Dr. Sharon Bergquist gives us a tour:
Stress, from the inside out
Stress is a natural physical and emotional response to challenges or being overwhelmed. It can be beneficial in short-term situations (e.g. escape from a tiger) but is harmful when prolonged or frequent (e.g. escape the rat-race).
Immediate physiological response: cortisol, adrenaline (epinephrine), and norepinephrine are released by the adrenal glands.
The effects this has (non-exhaustive list; we’re just citing what’s in the video here):
- Cortisol impairs blood vessel function, promoting atherosclerosis.
- Adrenaline increases heart rate and blood pressure, leading to hypertension.
- Stress disrupts the brain-gut connection, causing:
- Digestive issues like irritable bowel syndrome and heartburn.
- Changes in gut bacteria composition, potentially affecting overall health.
- Cortisol increases appetite and cravings for energy-dense “comfort foods”.
- This in turn promotes visceral fat storage, which raises the risk of heart disease and insulin resistance.
- Immune-specific effects:
- Stress hormones initially aid in healing and immune defense.
- Chronic stress weakens immune function (by over-working it constantly), increasing susceptibility to infections and slowing recovery.
- Other systemic effects:
- Chronic stress shortens telomeres, which protect chromosomes. Shortened telomeres accelerate cellular aging.
- Chronic stress can also cause acne, hair loss, sexual dysfunction, headaches, muscle tension, fatigue, irritability, and difficulty concentrating.
So, how to manage this? The video says that viewing stressful situations as controllable challenges, rather than insurmountable threats, leads to better short-term performance and long-term health.
Which would be wonderful, except that usually things are stressful precisely because they are not entirely within the field of our control, and the usual advice is to tend to what we can control, and accept what we can’t.
However… That paradigm still leaves out the very big set of “this might be somewhat within our control or it might not; we really don’t know yet; we can probably impact it but what if we don’t do enough, or take the wrong approach and do the wrong thing? And also we have 17 competing stressors, which ones should we prioritize tending to first, and…” and so on.
To that end, we suggest checking out the “Want to learn more?” link we drop below the video today, as it is about managing stress realistically, in a world that, if we’re honest about it, can sometimes be frankly unmanageable.

Health Tips for Males Too
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 Q&A Day at 10almonds!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝Articles are very informative and helpful. Maybe it’s me but things seem to lean more toward females. That being said don’t forget us males❞
Rest assured, we could never forget you! We try to make as much as possible of our content applicable to as many as possible of our readers, but of course not everything can be relevant for everyone.
This is, presumably, in response to our recent feature on menopausal health, because previous to that, our next-most-recent main feature that centred women’s health was a month ago—that was about breast cancer, and did have a section on breast cancer in men too. You might also enjoy the book we reviewed recently about prostate health, or our regular sponsor offering testosterone therapy. Please feel free to check out our articles on saw palmetto against male pattern baldness and BPH, as well as mental health issues that disproportionally affect men.
And of course, if you have specific questions/requests about men’s health (or any other health topic) we’re only ever an email away (or use the handy feedback widget, as you did to make this request)!

Immunity – by Dr. William Paul
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.
This book gives a very person-centric (i.e., focuses on the contributions of named individuals) overview of advances in the field of immunology—up to its publication date in 2015. So, it’s not cutting edge, but it is very good at laying the groundwork for understanding more recent advances that occur as time goes by. After all, immunology is a field that never stands still.
We get a good grounding in how our immune system works (and how it doesn’t), the constant arms race between pathogens and immune responses, and the complexities of autoimmune disorders and—which is functionally in an overlapping category of disease—cancer. And, what advances we can expect soon to address those things.
Given the book was published 8 years ago, how did it measure up? Did we get those advances? Well, for the mostpart yes, we have! Some are still works in progress. But, we’ve also had obvious extra immunological threats in years since, which have also resulted in other advances along the way!
If the book has a downside, it’s that sometimes the author can be a little too person-centric. It’s engaging to focus on human characters, and helps us bring information to life; name-dropping to excess, along with awards won, can sometimes feel a little like the book was co-authored by Tahani Al-Jamil.
Nevertheless, it certainly does keep the book from getting too dry!
Bottom line: this book is a great overview of immunology and immunological research, for anyone who wants to understand these things better.
