Surgical treatment is recommended for sebaceous cysts. Sebaceous cysts are not true tumors, but are cysts formed by sebaceous glands that cannot be excreted in time, and are most common in areas where sebaceous glands secrete abundantly, such as the head, back, and perineum. Sebaceous cysts have small black dots on the surface of the sebaceous gland openings, and within the capsule is an accumulation of sebaceous glands and epidermal keratinized material, which when squeezed will result in a tofu dregs-like secretion with a peculiar odor. Generally, small sebaceous cysts are recommended to be observed and can be left untreated; for large cysts, surgery is needed to remove them completely. If there is secondary infection, the infection should be actively controlled and surgically removed after the inflammation subsides. If you suffer from sebaceous cysts, you should go to a regular hospital for a surgical examination and follow the doctor’s instructions for treatment.
