Abstract

Prostate cancer remains a major health challenge for men across the world, especially as global lifestyles change. Several choices people make in daily living — from what they eat to how they sleep — directly impact their chances of developing this silent but deadly disease. This paper explores the top ten lifestyle choices that raise the risk of prostate cancer, according to respected oncologists and the latest research studies. We use real-world African and international case studies to humanise the information, and explain pathophysiology in simple English. The paper aims to educate men, caregivers, and the broader community, using an easy-to-understand approach that supports prevention and early detection.

Introduction

Prostate cancer is now the second most common cancer among men globally (Sung et al., 2021). In Africa, it is especially serious because many cases are diagnosed too late, leading to high death rates (Adeloye et al., 2016). While factors like age, family history, and genetics cannot be changed, many lifestyle habits can be controlled. It is now clear from numerous studies that poor lifestyle choices may create the perfect environment for cancer cells to grow inside the prostate gland.

The prostate is a small gland found just below the bladder in men. It produces the fluid that nourishes and transports sperm. As men grow older, their prostate cells can change. Sometimes, these changes become cancerous. Understanding how everyday behaviours influence these changes can save lives.

In this paper, we discuss the top ten risky lifestyle habits based on advice from leading oncologists, real patient stories, and the latest global and African research findings. Let us explore these habits one by one.

Top 10 Lifestyle Choices That Increase Prostate Cancer Risk

1. Poor Diet (High in Red Meat, Processed Foods, and Low in Fruits and Vegetables)

One of the clearest links to prostate cancer is an unhealthy diet.
Studies show that eating a lot of red meat (like beef and pork) and processed foods (like sausages, canned meats) increases inflammation in the body (World Cancer Research Fund, 2018). Inflammation can trigger abnormal cell growth in the prostate.

Pathophysiology:
High-fat diets promote oxidative stress — meaning there are too many harmful molecules (free radicals) in the body. These molecules damage the DNA inside prostate cells, leading to mutations that can cause cancer (Bostwick et al., 2004).

Case Example:
Mr. Daniel, a 57-year-old businessman from Lagos, Nigeria, ate red meat daily and rarely touched fruits. After months of urinary issues, he was diagnosed with prostate cancer. His oncologist explained that changing his diet earlier could have reduced his risk.

2. Obesity and Being Overweight

Obesity does more than harm your heart; it also raises your risk for aggressive prostate cancer (Gong et al., 2007).

Pathophysiology:
Fat tissue increases the production of certain hormones like insulin and oestrogen, which promote cancer cell growth. Obese men often have lower testosterone levels, creating a hormonal imbalance that encourages prostate cancer (Allott et al., 2013).

Real-World Scenario:
In South Africa, research found that overweight black men had a significantly higher chance of presenting with advanced prostate cancer compared to their normal-weight peers (Tindall et al., 2014).

3. Lack of Physical Activity

Physical inactivity is linked to higher cancer risks, including prostate cancer (Kenfield et al., 2011).

Pathophysiology:
Exercise helps regulate hormones, reduces inflammation, and boosts the immune system’s ability to destroy early cancer cells. Without exercise, these protective mechanisms weaken.

Example:
John, a retired teacher in Accra, Ghana, stopped exercising after retirement. Five years later, he faced a diagnosis of prostate cancer. His doctors believe regular exercise could have delayed or even prevented the cancer.

4. Smoking

Smoking is usually associated with lung cancer, but it also plays a role in prostate cancer.

Pathophysiology:
Tobacco smoke introduces carcinogens (cancer-causing chemicals) into the bloodstream. These chemicals can reach the prostate and damage DNA, leading to cancer development (Giovannucci et al., 1999).

Real-World Story:
A study from Egypt showed that men who smoked more than one pack a day had a 35% higher chance of dying from prostate cancer than non-smokers (Abdel-Rahman, 2019).

5. Heavy Alcohol Consumption

While moderate drinking may not be harmful, heavy alcohol use increases prostate cancer risk (Dal Maso et al., 2016).

Pathophysiology:
Alcohol metabolism produces acetaldehyde, a toxic chemical that can directly damage DNA and promote cancerous changes. It also weakens the immune system’s cancer-fighting capabilities.

Example:
Musa, a 60-year-old farmer from Kenya, drank heavily for decades. After his cancer diagnosis, his oncologist explained how alcohol had likely contributed to his disease.

6. Chronic Stress and Poor Mental Health

Chronic stress has surprising links to prostate cancer.

Pathophysiology:
Long-term stress releases high levels of cortisol (stress hormone), which weakens the immune system and increases inflammation. Stress also encourages risky coping behaviours like smoking, drinking, and poor diet, indirectly raising cancer risk (Powell et al., 2013).

Example:
Joseph, a widower in Uganda, went through years of emotional stress. He developed prostate cancer at 62. His doctor emphasized the need for mental health support as part of cancer prevention.

7. Sleep Disorders and Night Shift Work

Bad sleep habits and night shifts disturb the body’s natural rhythms.

Pathophysiology:
Poor sleep reduces melatonin production. Melatonin protects against cancer by regulating cell growth. When melatonin is low, prostate cancer cells can grow unchecked (Sigurdardottir et al., 2013).

Real-World Story:
A study in Senegal linked poor sleep among factory workers to higher prostate cancer risks (Ndoye et al., 2020).

8. High Calcium Intake (Through Supplements)

While calcium is vital for strong bones, too much calcium, especially from supplements, may raise prostate cancer risk.

Pathophysiology:
Excess calcium can suppress levels of calcitriol (vitamin D’s active form), a hormone that slows prostate cancer cell growth (Rowland et al., 2012).

Example:
Mr. Otieno in Nairobi took high-dose calcium pills daily without medical advice. Later, he developed prostate cancer. His urologist suspected the supplements played a role.

9. Unsafe Sexual Practices

Sexual health also matters.
Some sexually transmitted infections (STIs) like HPV (human papillomavirus) have been linked to prostate cancer (Isaacs et al., 2009).

Pathophysiology:
Chronic inflammation from infections weakens prostate cells, making them more prone to becoming cancerous.

Example:
A study in Zimbabwe found that men with histories of STIs had a slightly higher risk of prostate cancer than those without (Chokunonga et al., 2013).

10. Delaying Regular Health Screenings

Many men avoid or delay prostate screening tests like the PSA (Prostate-Specific Antigen) blood test.

Pathophysiology:
Without early detection, prostate cancer grows silently and spreads. By the time symptoms appear, treatment becomes harder and survival rates drop.

Case Study:
Samuel, a carpenter in rural Uganda, never attended health screenings. By the time he noticed trouble urinating and back pain, his cancer had spread to his bones.

Conclusion

Prostate cancer is not just a disease of fate; it is also shaped by the choices men make every day. By understanding and changing harmful lifestyles — eating better, moving more, quitting smoking, drinking less, managing stress, sleeping well, and going for regular screenings — men across Africa and the world can take control of their prostate health.

Governments, community leaders, and healthcare providers must work together to spread this life-saving knowledge, using culturally relevant education that respects the realities of daily African living.

Every small change counts. By acting now, we can reduce the burden of prostate cancer for future generations.
