@Sharontrains I have a hardish lump near my scar
as well (the surgeon and ultrasound called it a seroma) I’m nearly 7 years from surgery it has been very slowly shrinking. It used to increase and shrink and hurt in the beginning. I do have lymphedema in the breast armpit and arm but only when I don’t move the arm enough. When I’m at work i do a lot of data entry being right handed the left just sits there. I know have the health app tell me what is to move every hour which helps remind that I need to get my arm up. I do lymphatic massage on the whole breast I don’t know if that’s why the seroma has been shrinking might have to ask your Dr. i don't see the surgeon anymore. Just oncologist.
I hope you get some answers soon.
Any sort of lump or change is always scary
