Prostate cancer is caused by changes in the DNA of a normal prostate cell. These changes can be due to a variety of factors, including age, race, family history, and obesity. The risk of prostate cancer increases with age, and it is most common in men over 50 years of age. Black men have a greater risk of prostate cancer than men of other races, and the condition is also more likely to be aggressive or advanced in this group. A family history of prostate cancer, especially if a close relative was diagnosed before the age of 60, can also increase the risk. Additionally, obesity and a diet high in calcium may be linked to an increased risk of developing prostate cancer
