Why is cancer a rare disease amongst blacks (Africans) than whites (Europeans)? In Nigeria, we hardly hear about people falling ill of cancer. Thus, is cancer somewhat racial?

In Nigeria and many other African countries, cancer often appears to be less common for several reasons. One of the biggest reasons is underdiagnosis. Many people who develop cancer are never formally diagnosed because access to advanced medical testing is limited. Hospitals may lack specialized equipment such as CT scans, MRI machines, or advanced laboratory testing that can detect cancers early. In rural areas especially, people may not visit hospitals when they first develop symptoms. Some people rely on traditional medicine or local healers, and by the time they seek medical care the disease may already be advanced or mistaken for another illness.

Another major factor is poor record keeping and weak national cancer registries. In many developed countries such as those in Europe and North America, there are strong national systems that record every diagnosed cancer case. These databases help researchers track how many people get cancer each year. In Nigeria, cancer registries exist but they do not cover the entire population, and many cases go unreported. Because of this, the official numbers may appear lower than the actual number of cases.

Life expectancy also plays an important role. Cancer is more common in older people. In countries with longer life expectancy, such as many European nations, more people live into their 70s and 80s, which increases the chances of developing cancer. In Nigeria, the average life expectancy is lower, so fewer people reach the age where many cancers typically develop. This can make cancer seem less common even though the risk is still present.

Diet and lifestyle may also influence cancer risk, but the relationship is more complex than simply saying natural food prevents cancer. Traditionally, many Nigerians eat fresh foods such as vegetables, fruits, grains, beans, and locally grown produce. Diets high in fresh plant foods can help reduce the risk of some cancers because they contain fiber, vitamins, and antioxidants. In contrast, some highly processed foods that are common in Western diets may increase certain health risks when consumed in large amounts over many years.

However, it is not correct to say that canned foods alone cause cancer or that people who eat them will develop cancer. Food preservation methods used in many developed countries are strictly regulated to ensure safety. Cancer risk usually develops from a combination of factors such as smoking, alcohol consumption, obesity, physical inactivity, environmental pollution, infections, and genetic predisposition.

In fact, some cancers are actually more common in Africa than in Europe. For example, liver cancer occurs more frequently in parts of Africa because of chronic hepatitis B infections and exposure to toxins like aflatoxin, which can grow on poorly stored grains and nuts. Cervical cancer is also more common in many African countries due to limited access to HPV vaccination and regular screening programs. Prostate cancer rates among African men are also among the highest in the world.

Another important point is awareness. In many Nigerian communities, cancer is not widely discussed. People may attribute symptoms to spiritual causes or other illnesses. Because of this, cases may remain hidden within families and communities, making the disease seem rare when it is actually present.

Economic factors also influence diagnosis and treatment. Many people cannot afford cancer screening or advanced treatments. Wealthier individuals may travel abroad or visit specialized hospitals where their cancers are diagnosed and treated, which is why it sometimes appears that cancer mainly affects elites. In reality, cancer affects people across all social classes.

Urbanization is also changing the situation in Nigeria. As cities grow and lifestyles become more similar to those in Western countries, cancer rates are gradually increasing. Factors such as smoking, processed food consumption, pollution, reduced physical activity, and longer life expectancy contribute to this rise.

Research from global health organizations shows that cancer cases in Africa are expected to increase significantly over the next few decades. This increase will mostly be due to population growth, aging populations, and lifestyle changes.

The key takeaway is that cancer is not a racial disease. It affects all human populations. Differences in reported cancer rates between Africans and Europeans are mostly explained by factors such as healthcare access, life expectancy, screening programs, lifestyle differences, environmental exposures, and data collection systems.

Improving cancer awareness, early detection, vaccination programs, and healthcare infrastructure will help reduce the burden of cancer in Nigeria and across Africa in the future.
