If you have paid good attention to risk factors as it relates to some diseases of health condition, you may find that people of darker skin colour are more prone to them. Prostate Cancer is one of such health conditions that men of African descent have a higher risk of developing.
In fact, research shows that men of African descent, particularly African American men, have a higher risk of developing prostate cancer and are more likely to experience aggressive forms of the disease.
Studies say several factors contribute to this increased risk. Let’s take a look at a few of them.
1. Lower Vitamin D Levels
Melanin in darker skin reduces vitamin D production.
Dark skin blocks more UV rays, leading to lower vitamin D synthesis in the body (1).
Vitamin D is believed to play a role in preventing cancer, and deficiency has been linked to more aggressive prostate cancer (2) (3).
Also, studies suggest that African American men often have lower vitamin D levels, which may contribute to their higher risk (4) (5).
2. Genetic Factors
Some genetic variations linked to this form of cancer are more common in men of African descent.
Researchers have identified specific genetic mutations that may make prostate cancer more aggressive in Black men (6).
The higher rate of family history of prostate cancer in Black communities suggests a strong genetic link.
3. Hormonal Differences
Studies suggest that African American men tend to have higher levels of testosterone, which may stimulate prostate cell growth and increase cancer risk.
Some research also links differences in androgen metabolism to prostate cancer severity (7).
4. Healthcare Disparities And Late Diagnosis
Limited access to healthcare can lead to delayed screenings, causing prostate cancer to be diagnosed at later stages when it’s harder to treat.
Socioeconomic factors may also influence diet, healthcare access, and exposure to environmental risks.
Some studies suggest implicit bias in healthcare may contribute to delayed or inadequate treatment for Black men.
5. Diet And Lifestyle Factors
Higher rates of obesity and poor diet among some Black communities have been linked to prostate cancer risk.

Diets low in fruits, vegetables, and omega-3 fatty acids may contribute to higher cancer rates.
Takeaway
Men with dark skin, especially African American men, have a higher risk of this form of cancer due to a combination of biological, genetic, lifestyle, and healthcare factors.
Regular screening, maintaining healthy vitamin D levels, and adopting a healthy lifestyle can help reduce the risk.
