I did one MRI guided biopsy (and had two previous lumpectomies) and then I chose to have a prophylactic DMX because I didn't want to do the protocol for high risk BC patients. This was presented to me as biannual exams with alternating Mammo and MRI - and essentially waiting for a path report/diagnosis every six months. Plus I did not want to undergo further biopsies, lumpectomies, or a single mastectomy - perhaps followed by second mastectomy. It was explained to me that having LCIS increased risk in both breasts. I am a one and done kind of gal so I go for practicality when making decisions. Having a DMX was my ideal solution. Like you, I have a history of maternal side BC ; lost several Aunts, Great Aunts, a cousin when she was in her 30s. My mom is still here at 89 but she hasn't had a mammo since ??? She is not concerned with having BC because she feels she has lived a long life and would not undergo treatment if diagnosed. I do not carry any BRACA mutation but do carry a BRIP1 that is located near to BRACA genes. BRIP1 is known to cause ovarian and uterine cancer and is suspect for BC - they need more data on BRIP1. I felt a DMX allowed me to live my best life. While our diagnosis are similar we all have different preferences, or realities, surrounding quality of life - and we are presented with different treatment options based on our individual cases. Were you presented other options over than the four MRI guided biopsies? I was told by my surgeon, and later genetic counselor, that we entitled to a prophylactic mastectomy, or double with LCIS, if our lifetime risk is above 20%. BTW I am happy with my choice because I know longer waiting for the other shoe to drop; having the DMX has brought my risk down for 40 to 3%. Wishing you clarity for any decisions, smooth sailing on the diagnostics or surgeries, and a good prognosis.
