Cancer itself doesn't cause infections, But infections have been known to suppress the immune system allowing cancer to flourish where it other wise would not. For example in HIV positive patients whose immune system has been allowed to deteriorate into full blown AIDS, they are susceptible to a form of cancer known as Kaposi's Sarcoma. Which the healthy immune system can normally protect the body from it. Also the Human papillomavirus HPV, which can be spread by sexual contact has been associated with cancer in any of the localised areas where contact with the virus has occurred. So there are some cancer causing viruses, And since the viruses are infectious, it could be argued by extension that some cancers can be infectious.
No...it's not infectious but ironically we are born with the cancer cell in our body. The problem is that when that cell mutate if your body defense system don't shut it down then the cell will reproduce more bad cell wich will attack any weaker part in your body causing a tumor and the spread of the desease.
