Lump in mastectomy scar
I had a lumpectomy, at the age of 40, for Lcis in the right breast in 2017. In the same year, I had a bilateral mastectomy with reconstruction because I could not control my anxiety. In 2019, I did lipofilling, after which oily cysts formed in both breasts.
Few days ago I had an ultrasound scan because a lump appeared on the scar tissue of the left breast (the breast removed prophylactically) which seemed more strange to me.The radiologist says that it is a hyperechoic nodule compared to fat, with benign features, very likely fibrotic changes and proposes an MRI in the fall, while the surgeon believes that it must be excised and that the chances of it being cancer are 50%. I'm very confused and I don't know which direction to take.
what do you think it could be?
