Thanks for writing to us.
An irritation of the nipple along with a palpable lump even if it is very small and there is no associated nipple discharge
needs to be investigated.
You must go for a mammography
and FNAC of the lump to know the nature of the swelling under the guidance of your gynaecologist.
I hope this information has been both informative and helpful for you.
