Lipomas do not usually cause pain and may be mildly painful when pressed. Lipomas are slow-growing lumps of fat, and the cause of their development has not been fully clarified; a genetic link is considered. Symptoms caused by lipomas are usually atypical and can be easily overlooked due to their small size and slow growth. Lipomas are usually located under the skin, are soft, move well, and usually do not cause pain. In some patients, pressing on the lipoma may cause obvious pain, which is mainly considered to be related to the invasion or compression of the surrounding skin nerves by the lipoma, causing pain. If the lipoma gradually increases in size and appears as a visible lump on the skin, it is recommended to go to the dentistry department of the hospital, and if necessary, to remove it completely through surgery.
