Hi,Dear thanks for the query to HCM virtual clinic.
I studied your query in full details updated from you.I understood your health concerns.
Based on your query data, In my opinion ,You should not worry and do as follows-
Get the Surgical opinion soon.
Get FNAC
biopsy of the Breast Hard Lump(Mostly-Fibroadenoma-Mouse lump)and of the Neck Lump.
Second lump in right breast-seems to have come no-where but as these lumps are known as Mouse of the Breast,its normal complaint from patients like you.
Get Mammogram/CT study of the Breast lump.
If things suggest,that these lumps are non-malignant forget till that time.
Do FNAC biopsy of these breast Lumps.Don't worry till You get these reports.
So answer to your question is YES,they are MOUSY breast lumps.
Hope this would resolve your query and worry.
Welcome for any further query in this regard to ME.I would love to help you out
Awaiting for any further query.
Wish you fast recovery from this intriguing health problem.
Have a Good Day.
