Could this be a sign of Uterus Cancer? - cancer in the uterus is it mortal

At least 3 times per month, I have (severe pain in the pelvic region most likely) of the uterus. Once you take an aspirin, I could not surprise me if this is a sign of cancer?
Besides pain, you feel a little heavy in that area.
