Can a pituitary tumor cause uterine cancer?
No, as far as I know, there is no direct link between a pituitary tumor and uterine cancer. You might think they were related, since the pituitary gland is a small organ in the brain that produces hormones that affect other organs in the body, like the uterus, and one of the risk factors of uterine cancers is believed to be an excess of the hormone estrogen, but from what I’ve read, problems with the pituitary gland have nothing to do with the risk factors of uterine cancer.
A tumor on the pituitary gland is unlikely to cause excess levels of estrogen, for instance; more commonly, symptoms involve a lack of these kinds of hormones, like a lack of menstrual periods or lactation in women. So I wouldn’t worry about a pituitary tumor and uterine cancer.
