<s>[INST] I ve had a lump in my armpit that has gradually increased in size over the years. When I first noticed it about 4-5 years ago it was probably the size of a small grape and now I d say its the size of a kumquat or a little bigger. ( sorry for the fruit analogies) It is fairly soft to the touch and doesn t hurt. Is this something I should be concerned about [/INST] Hello there, Thanks thanks for your query on Chat Doctor. I carefully read your post and understand your point of concern.Don't worry I think it is a lipoma, which arises from fatty tissue, and never turn into serious issue for health except the pressure effect in case of large lipoma. You mention the size, I think you should not concern about this unless you have a cosmetic issue. If it will increase in size and affect your normal function then you can go to a general surgeon for excision. Hope it will help you, wish your good health. Regards </s>
