Urologists downplay cancer link to vasectomy
A study published in the Journal of Clinical Oncology last week found that vasectomy was associated with a small increased risk of prostate cancer and the risk was elevated for high-grade and lethal tumours (defined as prostate cancer death or distant metastasis).
Urologist Dr Shomik Sengupta, the leader of the Genitourinary Oncology Special Advisory Group of USANZ, said the same researchers had published similar findings before.
“However, multiple other studies have failed to bear out this relationship and meta-analyses suggest that there is no significant risk of prostate cancer conferred by having a vasectomy,” Dr Sengupta said.
The study was conducted by the Harvard School of Public Health and analysed data from 49,405 US men who were followed for up to 24 years from 1986–2010.
