This is Dr. David
you could be having an infection in your breast causing swelling and enlarging lymph nodes
I would repeat the breast ultrasound at this point.
and try a course of antibiotics
let me know if you have questions.
I am a cancer doctor
chance of breast cancer is low at your age
I would treat for infection first.
ultrasound would have seen most breast cancers if it was there.
and it didn't see a breast cancer.
I'm surprised you haven't started a course of antibiotics.
it is normal for one breast to be slightly larger than the other.
so if one breast is larger than the other, it is really not considered "swollen"
all of your biopsies have been negative
you don't have breast cancer.
you may not have any infection if you don't have redness and warmth of your breast.
I can't examine you so I don't know how "swollen" your breast is
