Hello, this is Dr. David. I have read your question and am ready to help.
There have been no cases of cancer spread through sex.
however, there are sexually transmitted viruses such as the human papilloma virus (HPV) which can put you at higher risk for developing certain cancers such as cervical cancer, anal cancers and even throat cancers and head and neck cancers can be induced by HPV spread.
HPV can spread even if you use a condom and can spread genital to genital or genital orally.
but direct cancer spread through sex has never been reported.
even if the cancer is in his kidney or bladder, cancer really can't spread through the urine either
I hope this helps.
let me know if you have other questions.
