I was Diagnosed DCIS Stage 0 in early Feb this year. I found out I was 5th woman in my family to have Breast Cancer so I did Bilateral Mastectomy with back-to-back reconstructive surgery as preventative measure. I tested negative for breast cancer gene. I did do strict Vegeterian diet for almost 60 days prior to my end of March surgery. Strongly recommend Chris Wark's book: Chris Beat Cancer. They also have cookbook: Beat Cancer Kitchen. He had Stage 3C Colon Cancer, did surgery but opted out of chemo and radically changed his eating and is still alive today. He has tons of info about studies that he cites for herbs/foods that are cancer preventive. I still eat this way about 90% of the time. For me, they only found 1 speck of invasive cancer so not doing radiation or hormone blocker, sentinel lymph node was negative so surgeon said there is no way it went anywhere else in my body. Research I read said that they are overtreating DCIS Cancer. Other research I have seen said that we need Estrogen to protect our bodies from disease. My Mom did Estrogen blocker but she had Stage 4 Breast Cancer and died last year, she lasted 4 years though so I think it helped keep her alive and with quality of life. I also had best friend with 2 forms of breast cancer, one that was very aggressive, she did surgery but did do Estrogen blocker for 5 years. I would encourage you to do lots of research for your situation. Hope your results come back negative!
