I am a 71 year old woman who has always enjoyed good health. I had a very small tumor and subsequently a lumpectomy. I had no cancer in lymph nodes or in margins. Next week I begin 5 days of radiation on partial breast only. My oncologist doctor has prescribed me 20 mg of tomoxifin to begin after radiation. I have done extensive research on this drug and will not be taking it as prescribed. Studies that I have read indicate that 10 mg of tomoxifin every other day or 5 mg daily produces the same results and far less side affects. I am planning to start 10 mg every other day but will switch to 5 mg daily if need be. 20 mg seems to be the standard prescribed without taking into consideration that every woman’s cancer may be different. For me it is a personal decision after extensive research from several countries. I am comfortable in my decision as at 71 years old it is about the quality of my remaining years.
