Late Nov 2010, I had pain and lump on my right breast in the inner quadrant. The doc sent me to mammogram and sonogram and did a biopsy on me. The result of the biopsy was fat necrosis and it was non malignant. He gave me a week's dosage of antibiotics which I took and the lump and pain went away by mid 3rd week Dec 2010. I went to see him for a follow up on 7 Jan 2011 and he said there is some left over lump which he has to monitor and I have to see him again in 3 mths time. However, now (mid Jan), the lump and pain has returned. Why is this happening again? Do I have to take another dose of antibiotics? Will the non malignant change to malignant? Help!!
