Most sebaceous cysts generally do not show obvious symptoms and do not cause pain. However, if the sebaceous glands grow and enlarge gradually, they will become painful, especially during squeezing or friction, which intensifies the pain. Once this condition is detected, it is best to go to a regular hospital's dermatology department where a doctor can perform minor surgery to completely remove the tofu-dregs-like substances and the cyst, thereby achieving a thorough cure. Regularly, one should standardize their diet and lifestyle habits, avoid spicy and irritating food, avoid staying up late, avoid anxiety, and refrain from bathing or swimming in public baths. It is also advisable not to keep small animals at home and to frequently sunbathe and sanitize bed linens and quilt covers.
