Lump in Bicep? What could it be?

Lipomas are soft and somewhat pliable although occasionally can be hard. Without an exam it is hart to tell. I hard, deep and attached to deep structures then you may need a MRI to make sure it is not a rare malignancy such as a sarcoma. If unsure what it is a needle biopsy can be performed giving you a diagnosis which would then guide the surgeon as to his approach. Fortunately a malignancy is very uncommon but can present the way you mentioned. See a board certified Plastic Surgeon or General Surgeon with experience in this area.

Lipomas are common and can be removed with small incisions.  Lipomas are benign tumors that can grow with time.

 

I use very small incisions to remove lipomas in my practice.

 I would suggest scheduling a consultation and examination and then a proper diagnosis should be given. It sounds like a lipoma or cyst and it is often best to remove these before they enlarge or grow over time depending on their location. Best regards, Michael V. Elam, M.D.
