I am a retired H&N surgeon, graduated from private medical college, department of medicine, athletic branch, tennis section. I consider that I was a "MONGOLIAN" doctor, although, I had tried my best to take care of my patients. My humble opinion, what made an individual to have cancer is , by far, not clear. No wonder the alternative managements including food therapy were accepted. Surgical management had helped a lot of patients, in the future, CHEMOTHERAPY , hopefully can help more patients. The eternal KEY is finding the cause of cancer.
