“When should I have a benign tumor removed?”

Make sure that isn’t malignant neoplasms. If it's benign in case of pain, radiculopathy, and increase in size, should be removed.

Usually a benign tumor is only removed if there is a risk of it becoming malignant or if it is causing symptoms. Otherwise, it is completely safe to observe

The axilla (armpit) is a very interesting anatomical part of the body. It contains many structures from skin, hair follicles, nerves, blood vessels, and lymph nodes to name a few. Any one of these structures can create a tumor. When I decide if a tumor is benign or not, I take several factors into consideration. If there is any doubt, I always do a needle biopsy to decide if the tumor needs to be removed. Usually tumors that are small and benign do not always have to be removed. We never wait for something to become malignant before we take it out. Benign tumors should be surgically considered if they continue to grow or cause symptoms like pain or become chronically infected or if they are cosmetically unsightly. If you have any concerns regarding your doctor's recommendations, go for another opinion.
Thanks for your question.
Best of luck!!!

It is difficult to answer that question without more information. Are you male or female? What is your age? How long have you had this mass? Is it growing? In general, the only one who can say a mass is definitively benign or malignant is a pathologist after a biopsy or removal. Otherwise it is just a clinical judgement. Reasons to remove a "Benign" tumor include:

-Pain
-Growth
-Disfigurement
-Diagnostic uncertainty

I hope that helps.

If it grows rapidly or changes, it needs to be evaluated for removal.

If it starts to grow or if it becomes bothersome like pain and discomfort

First of all, you need to be sure that it is some image guided biopsy. Once you are sure it is, then it is your choice as to when to have it removed, however, in general, I recommend that people simply remove them.
