Lipomas refer to a very common non-malignant soft tissue growth that consists of fat cells, which lies beneath the skin, appearing as a bump or raised area. The neck, upper arms, armpits and torso along with the upper thighs are common sites of lipoma growth. However, they may develop in virtually any area of the body. They typically have a soft, rubber like consistency. Lipomas grow at a very slow rate and may remain the same size for years. The growths most often appear during middle age. Men or women may develop lipomas, though men often have multiple growths.
