Roughly 3 weeks ago I found out that I have a large cancerous tumor at the opening to my cervix. The gynecological oncologist says that it is uterine cancer and I was scheduled for a hysterectomy and removal of my ovaries and tubes. I had a CT scan to study the tumor and at that time they found a mass in my right kidney. I saw the urologist earlier this week and it is kidney cancer. I now will have my kidney removed with the other parts. Both doctors say that the 2 cancers are unrelated and it would be extremely rare for either cancer to spread to the other location. How can I have two different cancers in my body at the same time? How common is that?
