Scientists have stated a link between the number of sexual partners and the risk of developing cancer. The conclusions were made, including by the staff of the University of England Ruskin, writes BMJ SRH.

As part of their work, its authors studied observational data on aging in people aged 50 and older. In total, we analyzed information about 2.5 thousand men and 3.1 thousand women, whose average age was 64 years. As a result, it was possible to conclude that the more sexual partners a person had, the higher the likelihood of encountering oncology. For example, women who had more than 10 such contacts had a 91% higher chance of developing cancer than those who had only one partner or none at all. For men, it was about 69%.
The authors of the study attribute this to the fact that with a greater number of intimate contacts, the risks of contracting STIs are higher, and they increase the chances of contracting cancer. While this does not confirm that having sex with multiple partners increases the likelihood of cancer, it does prove a connection, scientists point out. Other accompanying factors were not taken into account in the framework of scientific work, which also affected the results.
