Could cancer be making my bladder very sensitive during sex?

Unlikely: There are many causes for havinf sensitivity in the bladder area. Although cancer may be included, it is unlikely. This is a fairly common complaint and is typically from an overactive bladder or bladder dysfunction, especially if the patient is young and healthy. Of course, other factors must be taken into account such as the patients age, blood in the urine, smoking history, etc.

Not likey: If you're worrying that pelvic pain during intercourse is related to bladder cancer, that is not very likely at all at 27 years of age. See a gynecologist to discuss your symptoms.
