Sebaceous cysts are caused by excessive secretion of the sebaceous glands, which leads to localized obstruction and forms a benign proliferation, resulting in a subcutaneous sac that encases a tofu-dregs-like material. Generally, this condition does not exhibit symptoms of deterioration. The most severe common symptom is that the cyst enlarges and causes local pain. When subjected to external pressure or friction, it may rupture and become infected. Once this condition is detected, it is advisable to seek surgical removal at the dermatology department of a standard hospital as soon as possible. Normally, surgery can completely eradicate the problem. It's also helpful to avoid spicy and stimulating foods, refrain from staying up late, and reduce anxiety and stress. Regular exercise, sweating more, and frequent bathing can all aid in treating this condition.
