I had a lump in my left breast about 7 months ago and I had a mammogram the doctor said it was nothing lately it has enlarged significantly?

Enlarging lump. Go back to your doctor to get re evaluated. If you feel like you have an enlarging lump, it needs to be addressed despite what the mammo/physical exam showed 7 months ago.
