Now I see why I had two biopsies while I was in hospital. The first one was to see IF I had cancer. The second biopsy was to remove the tumor with clean margins (The part of the tumor that had migrated into the esophageal area the surgeon could not get a clean margin around. He used a cancercide drug to kill the cancer cells that may have remained at that place in my body.) I refused further medical treatment because the tumor was bloody (it made me anemic) and 5 cm in diameter. I had reason to believe that micro-metastases had already spread throughout my body.
