Concerns about Breast Health and Surgery

I had a lumpectomy in my left breast in March 2022. In January of this year I found a new one. I went to my specialist and she said it was fat necrosis and not to worry about it. well in August it felt like it was getting better. I went to get a mammogram and they said it is benign but I have a sunken feeling that it is not. I am having my second lumpectomy in December cuz it hurts and now my underarm is starting to hurt with a new lump between my breast and collarbone on the left size. Do I need to worry? I have not told anyone about my worries. I have been laughing at it and trying to play it cool. but inside I am freaking out
