Mine was ductal. I had 3 symphonies removed that were negative. The tumor was tested and was a 17, which they said was very low, about a 2% recurrence rate. I did a lot of research and learned 1. Get your immune system up. 2. Exercise. 3. Eat clean; as close as you can get from farm to table. A lot of berries and leafy greens. I'm not getting radiation or taking hormone blockers. I don't think the benefits out weigh the side effects.
