I have stage four metastatic breast cancer. I had it first in 2005. Then in 2018 it came back in my ovary. My tumor markers stayed in the normal range for about three years. Now they are rising every month. They are way out of normal range now. My oncologist has done every scan possible and we cannot find the cancer. She is now suggesting doing a spinal tap. Has anyone had that done and what results became of it??
Thank you for your help
