McCutheonmom,
I would be interested to know the success rate of alkaline treatments and oxygen therapy. Don't ignore MLM but don't ignore your doctor either. Many people out there are preying on desperate cancer victims. The best defense is education. Get on the internet and search.
Chemotherapy and/or radiation is recommended after surgery to kill cancer "seeds" left in the lymphatic and circulatory system. Surgery is not a guarantee that the cancer will not return.
A combination of changing your lifestyle and listening to your doctor is a prudent course. Its your decision. Good Luck.
