Unpopular for more than 20 years, circumcision may come back into vogue as new research point to some irrefutable benefits.
Protect against HIV
Circumcised men have up to 60 percent lower incident of HIV. That’s because the foreskin has a relatively high numbers of target cells for HIV infection. It’s also more likely to tear during sex,providing an entry route for HIV.
“Removing the foreskin removes the main site of HIV entry into the penis,”says HIV researcher Professor Roger Short, from the Department of Obstetric & Gynaecology at the University of Melbourne. “ Circumcision’s protective effect is proven beyond doubt.”
Cuts rates of cervical cancer
Human papillomavirus (HPV) can cause cervical cancer and surveys show that circumcised men are three times less likely to carry the virus. “Studies report at 58% reduction in cervical cancer risk among women whose partners were circumcised,” says Dimitrios Trichopoulos,professor of cancer prevention at the Harvard School of Public Health.
Less prostate cancer
Circumcised men have a lower risk of prostate cancer,”There is evidence that foreskin infections track up the urethra,”says Professor Tim Oliver from the Institute of Cancer,Queen Mary University,London.Slow healing infections increase prostate cell division,”Each division allows a chance for DNA damage,says Oliver.”For some patients this ends in cancer.”
Less penile cancer
Although it’s a rare cancer,circumcision almost eliminates the chance of invasive penile cancer.
Fewer infections
Urinary tract infections (UTI) are up to five times less common in boys who’ve been circumcised. However,the number of boys who will get UTI is small. Several infections at an early age can lead to kidney problems later in life . RD Health
