Hello, this is the first time I write in this specific discussion forum (although I use the other ones) because until Tuesday I thought there was no history of breast cancer in my family. I had breast cancer with recurrence in 2005 and 2006 (triple negative), I have an aunt who got BC in her 60s and a mother who died of endometrial cancer (at age 62), but a rare an aggressive form, with a cellular type similar to ovarian cancer (serous papillary).
The geneticist told me they would look for a mutation in the BRCA1 and 2 genes, but also in two other genes. Anyway, she said that even if they don’t find any mutation in these genes, she is pretty convinced that this is a hereditary form of cancer, because the endometrial cancer my mother had seems to be related somehow (but not proven yet) to the ovarian-breast hereditary cancer. So there could be mutations in other undiscovered genes. She suggested that I should consider either monitoring or removing the left breast (they only one left), ovaries and uterus.
I am 41 with no children. Although I am not scared (a bit traumatised at the moment!) about doing that (I am prepared to do anything I can to try to avoid going through this again), I am a bit worried about my sister, which, according to this, should consider the same surgeries despite not finding the mutation.
The geneticist is part of a group leaded by a very famous oncologist, so I trust them completely because I know their work, but I wonder if anybody else had a similar experience.
thank you so much for your help!
