Via The Independent: Prostate cancer ‘could be a sexually transmitted disease’, scientists say. Excerpt:
Prostate cancer could be a sexually transmitted disease caused by a common infection passed on during intercourse, scientists are claiming.
Research by the University of California found a sex infection called trichomoniasis supported cancer growth when a team of scientists tested human prostate cells in a laboratory.
Trichomoniasis is the most common non-viral sexually transmitted infection and is understood to have infected an estimated 275 million people around the world.
Infected men can experience pain during urination and thin white discharge from the penis. In women, the infection may trigger soreness and itching around the vagina and a change in discharge, although half of all men and women show no symptoms at all.
The study, published in the Proceedings of the National Academy of Sciences (PNAS), discusses how the STI could make men more vulnerable to cancer. However, Cancer Research UK has said it is too early to add prostate cancer to a list of other cancers caused by infections.
This research follows a study conducted by the Harvard School of Public Health in 2009, which found a quarter of men with prostate cancer showed signs of trichomoniasis and were more likely to have advances tumours.
