Small lump during breastfeeding

Hi Dr, I’m 34yrs old, a mother of 3. and I’m breastfeeding a 11months old baby. Recently detected a lump on left breast and ultrasound shows it is solid. Dr concluded that it is a benigh/fibro adenomas, the size is 4.5mmx2.5mm. Dr advise me to remove it thru surgery but I would prefer to continue breastfeed my baby, can I wait till my baby wean? says about one or half year later then only remove it? is there any risk? really appreciate your help and advice.

THE BREAST DOCTORS SAY:

It is quite common to have such small lumps in the breast, usually benign fibroadenomas.  When you are breastfeeding, the lumps could also be lactational adenomas, which are due to the active milk-producing glands.  If there are no suspicious features or risk factors for breast cancer, you may continue to breastfeed your baby.  The ultrasound should be repeated every 3-6 months to establish that the lump is not increasing in size.  If it is growing bigger, than you should stop breastfeeding to consider a biopsy.  If the lump is a lactational adenoma, it should reduce in size when you stop breastfeeding.
