My 65 Year Old Mother Had Noticed Something Pushing Against

My 65 year old mother had noticed something pushing against the walls of her vagina so much that it was protruding outward, and she had heavy discharge. She had an MRI and they discovered a large mass in the lower right pelvic region. There is also a suspicious looking spot on her uterus. What are the chances of cancer? She has been told to make an appointment with the oncologist this week.
