I had a breast reduction almost 7 months ago. How could I get my scar fixed? (Photo)

I had breast reduction almost 7 months ago. I had an open wound and had to go to a wound care center. I currently have to hard lumps at the top of my breasts I think is fat necrosis. Could that be removed by making a small incision at the top? I’m afraid of going under and having my nipples removed do to me having superficial necrosis on one. Is not that bad now but I am afraid of having more complications. I would like to know my options for the scar and the Lumps
