Bone Cancer Knee If You Have Cancer In The Knee Area, What Kind Is It?

If you have cancer in the knee area, what kind is it? - bone cancer knee

Is a cancer of the knee? Or is that the bone cancer? My mother will know on Monday for a scan to see why you have pain in the knee. She has had breast cancer and skin cancer that we want to make sure that this is not the cancer that is causing the pain. Thank you!
