All I can say is Hooray for your sister! My oncologist has a news letter and he just wrote about metastatic BC. He said, and I quote "I am telling women with metastic disease that they should consider themselves living with a chronic disease that will require appropriate treatment rather than a 'terminal' disease. This is very good news and I am so happy to hear such optimistic news. He also goes on to say "that the most siginicant thing they can do to impact their breast cancer risk is to do aerobic exercise 5 hours per week and reduce their caloric intake from fat to 20% of thie daily caloric intake." I think eating properly and getting in that aerobic exercise is still part of the battle against BC. I don't mind the exercise but I am having a hard time giving up my chocolate! Best wishes to your sister and my she live a long and healthy life.
