I'm not considering a mastectomy. I'm questioning whether it's necessary to have a lumpectomy when my ADH diagnosis was non cancerous. In my research, I found that as little as 20% of women with this diagnosis go on to develope cancer, and that was without doing any preventative strategies such as monitoring with regular mammograms or meds to decrease estrogen production. Even so, the % is even less in the first 5 years. I'm 78 yrs old with no risk factors so I feel unlikely to die from breast cancer. Thoughts?
