Hello,
If these lumps are lipomas which are quite common in the area then they should be got removed if they are cosmetically unpleasant or causing any symptoms like nerve compression or pain. However you have not mentioned the nature of the lumps. In that case it is better to get a FNAB (fine needle aspiration biopsy) of the lumps done to confirm the diagnosis.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
What was the diagnosis? "lumps" is not specific.
