STIs are the principle suspect on this elevated threat of most cancers, however individuals with more intercourse companions additionally tended to bask in different dangerous behaviors, Smith famous.
“In our study, those with a greater number of sexual partners were more likely to smoke cigarettes and drink alcohol frequently, behaviors known to be associated with cancer risk,” Smith mentioned. “It is possible that the number of sexual partners one has had captures a combination of likelihood of exposure to STIs and lifestyle profile.”
The examine was revealed Feb. 13 within the journal BMJ Sexual & Reproductive Health.
Two U.S. well being specialists not concerned with the examine commented on the findings.
While attention-grabbing, this examine has flaws that make it laborious to attract significant conclusions about what it discovered, mentioned Dr. Konstantin Zakashansky, an affiliate professor of obstetrics, gynecology and reproductive science with the Icahn School Medicine at Mount Sinai in New York City.
Sex and most cancers are each sensitive topics, and it is questionable whether or not one can belief individuals to precisely report both their promiscuity or their most cancers prognosis, Zakashansky mentioned.
“The problem is people over-reporting, underreporting. You don’t know how truthful they are,” Zakashansky mentioned. “There’s also recall bias, where they genuinely don’t remember.”
These are actual issues with the examine, agreed Mia Gaudet, scientific director of epidemiology analysis with the American Cancer Society.
But Gaudet mentioned that the report does shine a highlight on a possible explanation for most cancers that requires additional analysis.
“The overall conclusions are consistent with what we know about the potential role of viruses in cancer, and support further study,” Gaudet mentioned.
Human papillomavirus (HPV) has been linked to cervical, oral, anal and penile cancers, she famous, whereas hepatitis B and C are tied to liver most cancers. It’s probably different viruses could possibly be linked to different types of most cancers.
“Sexual health is something that’s understudied because of the taboos around it. While this study isn’t ideal, it’s helpful to have some information around this space,” Gaudet mentioned.
In the meantime, individuals who’ve been promiscuous ought to discuss with their physician, Smith urged.
“People who had risky sexual encounters should contact their health care providers to get checked for potential sexually transmitted infectious and should discuss openly about how to minimize this risk,” Smith mentioned. “Using appropriate protection will reduce the risk of related cancers going forward.”
