I discovered a lump in my right breast in 2008 (?) and had a lumpectomy, the
surgical site never healed. Multitudes of doctors and tests later, I was diagnosed with GM. I eventually "recovered" in 2010, by having a partial mastectomy of that breast. I've never had a flare up in that breast since.
2012: I discovered a lump in my LEFT breast, similar to the original one in my right. After imaging, a core biopsy, was determined it was GM, again. Treatment began again.
