Truly gutted for you. I chose a bilateral mastectomy with reconstruction because my original cancer wasn't visible on a mammogram 5 weeks before hand and if it had been deeper in my breast and not easily found by myself..well we wouldn't be having this conversation possibly or I would be stage IV at the very least due to my aggressive Es+Pr-Her2+ grade 3 tumour. I knew for me it was the best option due to breast density and my family history with an Aunt who had bilateral breast cancer.
I certainly miss my breasts but have never regretted the decision.
I know statistically lumpectomy with radiotherapy do just as well. My fear was that early detection in my breasts was difficult and therefore too risky.
It is a personal choice and no answer is wrong. You just have to chose with your surgeon the right decision for you..
Hope treatnent is kind. There are a number of women here who have gone through similar who I am sure will link in with you. Kath x
