If the lump in the arm is caused by a trauma or inflammation then it does not require any treatment and it resolves on its own. If the arm lump is caused due to a benign cyst or tumor then also it may not be removed and treated conservatively unless it is embarrassing for the individual and the protrusion is a little too big. Surgery may also be considered if there is a compression of surrounding structures or a malignant tumor is diagnosed. These arm lumps usually do not infiltrate into surrounding tissues hence they can be excised easily.
There is also an alternative to the standard excision process which is squeezing the arm lump manually by making a small nick in the skin. Another technique known as Liposuction-assisted Lipectomy has also been effectively used for excision of Lumps in the Arm with minimal complications.
