I was diagnosed with DCIS with Estrogen and Progesterone as well and was treated at Memorial Sloan Kettering (who are amazing btw). Their recommendation was lumpectomy with radiation and 10-15 years of hormone therapy (tamoxifen). However, I have a History of kidney cancer and my sister a history of triple negative breast cancer, along with an unreal number of immediate family members with cancer so I asked about a bilateral mastectomy with reconstruction. They agreed, saying that they usually recommend the treatment I initially discussed but because I asked about the bilateral mastectomy and I was more interested in that route, plus the personal and family history of multiple cancers, they agreed and encouraged my request. Everything was removed and tested and it was determined no treatment is necessary because I've removed the possibility of it returning. I wasn't even recommended to see a medical oncologist. I do have a medical oncologist anyway outside of Sloan for my kidney cancer, so I met with her as well and she felt the same way. At this point, I've stopped birth control and any outside hormone input into my body including soy and soy related products.
