Some cancers are, in fact, spread from person to person. The HPV virus, for example, is responsible for many instances of cervical cancer - and I'm pretty sure it can cause throat and/or penile cancer as well. Not everyone that gets the virus gets cancer, but it is exceedingly common.
- benchaney 10y agoMy understanding is that the virus increases the likelihood of contracting cancer because it suppresses the immune system, which is normally responsible for killing cancer cells. The cancer itself is still the result of a mutation in a healthy cell from the same person who has contracted it.
