A hard lump under the chest may be considered sebaceous cysts, lipomas, etc., and can be treated according to the specific situation.
1. Sebaceous cysts: Sebaceous cysts are mainly manifested by round or oval bumps with black dot-like openings in the center of the bumps, and white secretion with foul smell can be squeezed out by pressing the periphery. It is easy to cause infection by squeezing with hands, and the treatment needs to remove the cyst through surgery.
2. Lipoma: It is a common benign tumor, mainly composed of fat cells. For the slow-growing and asymptomatic lipoma, no special treatment is needed, and observation can be given; for the larger and faster-growing ones that compress the nerves or organs, surgery can be chosen to remove them.
If you find hard lumps for unknown reasons, it is recommended to consult a doctor for a clear diagnosis and symptomatic treatment, and do not deal with them blindly on your own.
