I’d never really thought about this issue until I read a study from the American Family Physician where some hardy souls sifted through the world literature for the answer to this very question. Their conclusion was that one out of every 220 women experiencing post coital bleeding has invasive cervical cancer.
The general prevalence of cervical cancer (in the US) is about 10 in 100,000.
So, if you’re experiencing bleeding after sexual intercourse, you should follow up with your Ob/Gyn to determine the cause. Also, regular pap smears are important in sexually active women as most cases of cervical cancer have no symptoms at all.
(How common is post-coital bleeding? About 1% of women report this problem.)
