Query: Get to the root cause of breast cancer

I had breast cancer on the same breast twice, in 1983 and again in 3/2001. I want to find the root cause as I do not want it to happen again. I find the book easy to read and understand. I will start the Wu Ming Meridian Therapy which seems easy to do. I will also start to take the healing food and herb listed in the book. Thank you Dr. Lu for helping me to heal. If I had a book like this in 1983, I probably would not have breast cancer again in March 2001. I have been recommending this book to other breast cancer survivers at my support group.
