Can I have my underarm lipomas removed while pregnant?

Thank you for sharing your excellent question.  Surgery is typically avoided for pregnant patients so I would wait until after delivery of your second child before seeking mass resolution.  Hope this helps.

It is generally recommend that pregnant and breast feeding women do not undergo elective surgical procedures.  This is out of an abundance of caution to insure there is no potential harm to the fetus or infant.  If it is determined that removal of the lipomas under your arms is medically necessary, then it may be able to be done.  I would discuss this with your obstetrician.  

Hi and welcome to our forum!
From your history, it is possible that the masses you describe may actually be islands of breast tissue, especially since you became symptomatic following your last delivery.
Unless for serious illness or disease, surgery during pregnancy is usually not recommended as it may pose a risk to the developing fetus. In addition, during pregnancy, the vascularity of breast tissue increases markedly as the glandular elements of the breast proliferate. This makes removal more difficult and risky.
I recommend you speak with your gynecologist regarding the necessity and safety of the proposed procedure.  
Best wishes...
