Lipoma changes. Is it possible for a lipoma to affect a nearby lymph node?

Thank you for sharing your question.  Certainly your description is possible but I would have the area examined by either your ob/gyn or plastic surgeon to ensure nothing of concern has developed.  You can then consider removal of the lipoma at your convenience.  Hope this helps.

Lymph nodes are reactive and may enlarge in response to an infection, injury or more serious issue such as cancer. It is doubtful that a longstanding lipoma would cause enlargement of a lymph node unless it was infected or recently injured (scratched for example). I recommend you get both lumps checked out by a physician to clarify exactly what the lumps likely are. The second lump may not be a lymph node and/or have nothing to do with your other mass. Benign things are common but armpit masses are occasionally more serious and should be investigated. Good luck and take care.
