I had cancerous calcification on my right breasts. i also had a lumpectomy and radiation, but why is the cancer coming back?

We Wish We Knew: There is nothing more frustrating than cancer recurrence, especially when one is given a "clean bill of health" after treatment. Unfortunately, some breast cancers can recur--if its in the breast alone, a mastectomy may be necessary; if its elsewhere in the body, this requires chemotherapy. If you are unclear about this, please discuss at length with your cancer doctor. Good luck!

Many reasons: Eveniin expert hands, cancer recurs in the same breast in 6-10% of women after a lumpectomy with radiation. It is usually in the same spot, but may be a separate cancer in another part of the breast (much less common). Recurrence is higher if you are young, have an aggressive tumor (triple negative), have a large tumor, did not receive chemo or endocrine therapy, or if margins were positive.
