Prostate cancer is cancer that develops in the prostate. Males have a tiny prostate gland that releases seminal fluid. This fluid transports and nourishes the sperm. Usually, prostate cancer grows gradually and is limited to the prostate gland. While there, it might not cause any severe implications. Even though some kinds of prostate cancer decrease gradually and need no or minimal treatment, others proliferate and are aggressive. So, let us find out the causes of prostate cancer. 

1. Obesity
In overweight people, the risk of developing prostate cancer is higher compared to others. Moreover, in overweight people, the likelihood of prostate cancer being more aggressive is high. Further, if you are overweight, there is a good chance that following initial treatment, cancer may relapse. Thus, to lower your susceptibility to prostate cancer, it is recommended to shed some weight.

2. Genetic factors
Inherited features, such as modifications in the BRCA1 and BRCA2 genes, can increase the likelihood of developing prostate cancer. It has been noted that mutations in these genes also aggravate the breast cancer risk in women. Further, in men born with Lynch syndrome, the risk of developing prostate cancer (and other kinds of cancer) is high.

3. Age
One of the key prostate cancer risk factors is age. The disease is more prevalent in young men. Following a study by the Prostate Cancer Foundation, only one in 10,000 American men below 40 developed prostate cancer. This number grows to one in 38 men between the ages of 40-59. Further, this number rises to an alarming number of one in 14 men between the ages of 60-69. Most prostate cancer cases are seen in men aged over 60. 

4. Family history
Men with relatives who have had prostate cancer are at a greater risk of developing the disease. If your sibling or father had the disease, your chances of developing the disease almost doubles. Studies suggest that your vulnerability to the disease is more than when your sibling has the disease. Your risk susceptibility to prostate cancer increases when more than one man in your family is affected. If your family has a history of prostate cancer, you must start cancer screening after turning 40. 

So, these some significant causes of prostate cancer that you should remember.
