Hi doc, can cancer be passed on by having sex etc..ie is it contageous especially nasal cancer?

No: A few viruses that create a cancer risk can get transmitted (notably some of the hpv strains); most people meet epstein-barr which causes some nasopharyngeal cancers but the cancer itself isn't contagious. Most nasal cancers are unconnected to any virus. Any special concerns, get with your physician.

Depends: There are few std's that are associated with cancers . Hiv, hpv. And hepatitis b are disease that can be transmitted through sex and all are associated with some kind of cancers. Good thing all are preventable . It is also true that not all persons having this disease get cancer.
