Signs and investigations: Your ideas about causes of prostate cancer
Your ideas about causes
Although the causes of prostate cancer are unknown, and the disease has a high prevalence among elderly men, some factors seem to be associated with a slight increase in the likelihood of developing the disease. These are having relatives who have had prostate cancer, and eating a diet high in animal fat or protein.
Some men saw prostate cancer as just part of 'old age' or 'just one of those things' although there may have been some confusion with other more common prostate problems such as benign prostatic hypertrophy (BPH). Men we interviewed suggested a variety of possible causes and often made the point that more than one factor is probably involved. Many believed that genetic factors were important. One man who thought that prostate cancer was inherited from family members', also felt that he was somehow responsible for any disease he had.
Elements of diet, especially dairy produce and meat, were often mentioned as a possible cause of prostate cancer and so was 'stress'. Other ideas about the causes of prostate cancer included vigorous sports or high levels of sexual activity, vasectomies*, exposure to chemicals, and electromagnetic emissions.
* There have been a number of studies about whether having a vasectomy increases the risk of developing prostate cancer. Most doctors believe that having a vasectomy has no effect on the risk of prostate cancer or that, if it does increase the risk, the effect of this is quite small. For more information on these studies see Macmillan Cancer Support and National Cancer Institute.
