A lipoma is a mass of fat cells in the subcutaneous fat layer with clear borders and an envelope that can be moved by pushing with the hand and is not fixed. Lipomas do not actually grow only in the chest, but anywhere in the body, with an envelope. Lipomas are benign tumors that do not metastasize and do not affect other tissues. It does not matter where the lipoma grows, in the chest or elsewhere. If the lipoma is painful locally, or increases significantly in a short period of time, or if the lipoma grows larger and compresses local tissues, causing local pain and discomfort and local dysfunction, it is recommended that the lipoma should be removed surgically. If the lipoma is benign, but causes local painful pressure or functional impairment, it can be removed surgically, and it does not matter where the lipoma grows.
