Beyond the myths about sex, enlarged prostate and “old age”, science points to age, ancestry, genes, family history, obesity, hormones and other factors that can increase a man’s vulnerability
For years, prostate cancer has been surrounded by a mixture of fear, misinformation and half-truths, with many men believing that the disease is simply an unavoidable consequence of ageing or something triggered by sexual activity, an enlarged prostate or particular foods.
But medical research paints a far more complex picture, revealing that prostate cancer develops through a combination of genetic, biological, environmental and lifestyle factors, many of which receive surprisingly little attention in everyday conversations about men’s health.
That distinction is important because having a risk factor does not mean a man will necessarily develop prostate cancer, just as the absence of an obvious risk factor does not provide immunity.
That distinction is important because having a risk factor does not mean a man will necessarily develop prostate cancer, just as the absence of an obvious risk factor does not provide immunity.
Cancer develops when cells in the prostate accumulate genetic and molecular changes that allow them to grow abnormally, evade the body’s normal controls and, in some cases, spread beyond the prostate.
For Nigerian men, this conversation deserves even greater urgency. Prostate cancer is one of the biggest cancer threats facing men in the country, and available global cancer data indicate that it is the leading cancer among Nigerian men in terms of both new cases and cancer deaths.

Yet many men still present for medical attention only after symptoms become difficult to ignore, by which time the disease may already have progressed.
So, what really increases a man’s risk?
Age remains the biggest warning sign
Growing older is the most established risk factor for prostate cancer, with the likelihood of developing the disease rising substantially as men move beyond middle age. Prostate cancer is uncommon among younger men, but its incidence increases sharply in later life because cells have had more years to accumulate genetic damage and other changes capable of disturbing normal growth.
Age, however, should never be interpreted as a guarantee that prostate cancer will occur. Many older men will never develop the disease, while younger men can occasionally develop aggressive forms, particularly when hereditary risk factors are present.
African ancestry puts men in a higher-risk category
One of the facts that deserves far more attention is the elevated burden of prostate cancer among men of African ancestry. Research has consistently shown that Black men have a higher incidence of prostate cancer and are more likely to develop aggressive disease and die from it than many other racial and ethnic groups.
Scientists have not attributed this disparity to one factor. Genetic susceptibility may contribute, but researchers are also examining differences in healthcare access, socioeconomic circumstances, environmental exposures, lifestyle and the stage at which cancers are diagnosed.
For African men, therefore, dismissing prostate cancer as a problem belonging to another population can be a dangerous mistake.
Family history can reveal a hidden vulnerability
A man’s family history can provide an important clue to his prostate-cancer risk, particularly when his father, brother or another close male relative has had the disease.
Risk becomes more concerning when several relatives have been affected or when a relative was diagnosed at a relatively young age. A family history of certain breast, ovarian, pancreatic or colorectal cancers can also be relevant because some hereditary cancer syndromes involve mutations that increase the risk of several different cancers.
This means men should know more than whether their father had prostate cancer. They should understand the broader cancer history of their close biological relatives.
Inherited genetic mutations can quietly increase risk
Modern cancer research has shown that some men inherit genetic mutations that make it harder for their cells to repair damaged DNA. Among the best-known are BRCA1 and BRCA2 mutations, with BRCA2 particularly associated with an increased risk of prostate cancer and more aggressive disease.
Other genes, including ATM, CHEK2, PALB2 and genes involved in DNA mismatch repair, have also been implicated in hereditary prostate cancer.
A man does not need to have a parent who was known to have cancer to carry one of these mutations. Genetic information can remain hidden in a family for generations, particularly where previous generations were never diagnosed or never had access to cancer testing.
Cancer can also arise from genetic damage acquired during life
Not every genetic change associated with prostate cancer is inherited. Cells continuously divide and repair themselves throughout life, creating opportunities for mutations and other molecular abnormalities to accumulate.
When changes occur in genes responsible for regulating cell growth, DNA repair and programmed cell death, a previously normal cell can gradually acquire characteristics that allow it to behave like a cancer cell.
This explains why prostate cancer can occur in a man with no known family history and why blaming the disease entirely on heredity is scientifically inaccurate.
Male hormones play a major biological role
Another subject frequently misunderstood is testosterone. It is common to hear that high testosterone directly causes prostate cancer, but the scientific picture is considerably more complicated.
Prostate cells depend on male hormones known as androgens, and testosterone is converted within the prostate into dihydrotestosterone, a more potent androgen. Androgen signalling plays a central role in normal prostate function and in the growth and survival of many prostate cancer cells.
This is one reason doctors use treatments that reduce or block androgen activity in men with advanced prostate cancer.
It would therefore be wrong to conclude that testosterone alone causes prostate cancer, but equally wrong to ignore the central role that androgen signalling plays in prostate biology and cancer progression.
Excess body fat may increase the danger of aggressive disease
Obesity has also emerged as an important part of the prostate-cancer conversation, although the relationship is more complicated than simply saying that being overweight causes prostate cancer.
Research has found stronger links between excess body fat and advanced, aggressive or fatal prostate cancer than with prostate cancer overall. Scientists are investigating several possible explanations, including changes in hormones, insulin signalling, metabolism, chronic inflammation and the biological environment surrounding developing tumours.
Maintaining a healthy weight therefore remains one of the sensible measures men can take, not because it guarantees protection from prostate cancer, but because healthy body weight is associated with better overall health and may reduce the risk of aggressive disease.
Diet matters, but miracle foods and forbidden foods are mostly myths
Food has become one of the most controversial aspects of prostate-cancer discussions, with claims circulating that particular foods either cause or cure the disease.
Scientific evidence does not support such simplistic conclusions.
Researchers have investigated dairy products, calcium, red meat, processed meat, vegetables, tomatoes, soy, coffee, fats and numerous other dietary factors, but the strength of evidence varies considerably from one factor to another.
What emerges more consistently is the importance of an overall healthy dietary pattern rather than dependence on a single “prostate-protecting” food or supplement. Men should aim for a varied diet containing vegetables, fruits, whole grains, legumes and other nutrient-rich foods while limiting excessive consumption of highly processed foods and maintaining a healthy weight.
Tomatoes may be nutritious, but they should not be presented as a cure. Likewise, a man should not abandon medically recommended treatment because someone has convinced him that a particular fruit, herb or supplement can eliminate cancer.
Some occupational exposures deserve more attention
Men can also encounter potentially harmful substances through their occupations, although the evidence linking specific workplace exposures to prostate cancer is not equally strong for every chemical or industry.
Researchers have investigated substances including arsenic and other chemicals, while firefighters and workers exposed to complex mixtures of combustion products have also attracted scientific attention.
This does not mean that every man who works around chemicals will develop prostate cancer. It does mean that occupational safety should not be treated casually, particularly where workers are regularly exposed to potentially hazardous substances.
Protective equipment, proper workplace controls and compliance with occupational-health regulations can reduce exposure to known hazards.
Inflammation remains an intriguing but complicated suspect
Inflammation has long been studied as a possible contributor to cancer development, and researchers have investigated whether conditions involving inflammation of the prostate could be connected with prostate cancer.
Some studies have reported associations between prostatitis and prostate cancer, but subsequent research has shown how difficult it can be to distinguish a genuine biological relationship from detection bias, since men experiencing prostate-related symptoms may undergo more medical examinations and consequently have cancers detected more frequently.
For that reason, chronic inflammation should not currently be presented as a simple, proven cause of prostate cancer.
It remains an area of scientific interest, but the evidence is more complicated than many health claims suggest.
What men should do to escape the menace
Knowing the risks is useful only if it changes behaviour.
The first step is for men to stop treating prostate health as a subject that should only be discussed when something goes wrong. A man should know his family cancer history, particularly whether his father, brothers or other close relatives have had prostate cancer or related hereditary cancers.
Age and ancestry should also form part of that conversation. A Nigerian man should not assume that being apparently healthy means he has no reason to discuss prostate cancer with his doctor.
Regular physical activity is another sensible defence. Walking, running, swimming, cycling, strength training or other forms of exercise can help maintain a healthy weight and improve metabolic health, even though no exercise routine can guarantee protection against cancer.
Men should also pay attention to their weight, diet, alcohol intake and tobacco use, not because each of these factors has been proven to directly cause prostate cancer, but because maintaining overall health reduces a range of chronic diseases and may influence the biological environment associated with cancer progression.
Most importantly, men should have informed conversations with qualified healthcare professionals about PSA testing and prostate-cancer screening, particularly when they have significant risk factors.
PSA testing is not a perfect cancer detector and can produce false-positive results or identify cancers that might never have become life-threatening. That is why screening decisions should be based on an individual’s age, risk factors, health history and informed discussion with a clinician rather than a blanket rule applied to every man.
Where a doctor recommends further assessment, men should not allow fear, embarrassment or stories about what happened to someone else to delay the process.
Don’t wait for symptoms
One of the most dangerous misconceptions about prostate cancer is that a man will know when something is wrong because he will have difficulty urinating, experience pain or notice changes in sexual function.
Early prostate cancer often produces no symptoms at all.
Urinary problems can be caused by benign prostate enlargement and other conditions, while prostate cancer can sometimes progress without producing obvious warning signs.
That is why waiting until urination becomes difficult is not a reliable strategy for protecting oneself.
Blood in the urine or semen, persistent urinary problems, unexplained pain or other unusual symptoms should be medically evaluated rather than automatically attributed to ageing.
The myths that men must abandon
Prostate cancer is not simply the result of frequent sex, masturbation or sexual inactivity, and there is no scientific basis for blaming the disease on sitting on a hot surface or on one particular sexual habit.
Neither is an enlarged prostate synonymous with prostate cancer. Benign prostatic enlargement and prostate cancer are different conditions, although a man can have both.
Similarly, cancer should not be blamed on one plate of food or one isolated lifestyle decision.
Perhaps the most dangerous myth of all is that prostate cancer is an unavoidable consequence of getting old.
Age increases risk, but ageing is not a diagnosis.
The real defence is knowledge
There may never be a single magic formula capable of preventing every case of prostate cancer, because the disease is driven by a complicated interaction between inherited genes, ageing, cellular changes, biological processes and environmental and lifestyle factors.
What men can control is how early they become aware of their risk and how seriously they respond to it.
Know your family history. Maintain a healthy weight. Stay physically active. Eat a balanced diet. Avoid tobacco and excessive alcohol. Take occupational exposure seriously. Do not rely on miracle cures or frightening social-media claims. Most importantly, discuss prostate health and appropriate screening with a qualified healthcare professional when your age or personal risk makes it relevant.
For Nigerian men, the message is even more urgent because of the country’s significant prostate-cancer burden.
The goal should not be to live in fear of prostate cancer. It should be to understand the risk well enough to give the disease less opportunity to become a silent killer.
Early awareness cannot prevent every case, but it can change the point at which a dangerous disease is discovered — and that difference can ultimately mean the difference between treatment, prolonged survival and a devastating late diagnosis.
