Sebaceous cysts are tumors formed by the accumulation of excessively secreted sebum from the sebaceous glands in localized areas. These cysts contain a substance resembling tofu dregs and mostly develop in areas with active sebaceous gland secretion. Generally, surgical removal is often completely effective. If the condition recurs, it indicates either significant local inflammation or incomplete removal during surgery. In such cases, it is advisable to visit a dermatology department at a reputable hospital for another minor surgery to ensure complete excision of the cyst sac. Additionally, it is important to maintain a proper diet and lifestyle, avoiding spicy and irritating foods, refraining from staying up late, and avoiding public baths and swimming pools. It's also advisable not to keep small animals at home.
