Sebaceous cysts are a type of benign hyperplasia and are somewhat related to the vigorous secretion of one's own sebaceous glands. This condition is generally not serious and mostly mild, with most cysts being relatively small, about the size of a mung bean. They may not require treatment and can be observed over a long period. If they gradually increase in size and cause pain, it is best to undergo a minor surgery at a dermatology department of a reputable hospital to completely remove them. Alternatively, treatment can be initiated early in the development stage of the sebaceous cyst. It is advisable to avoid spicy and stimulating foods, try not to stay up late, and regularly engage in exercises to sweat more and take frequent baths. These measures help prevent the recurrence of the condition. During the development of a sebaceous cyst, it is also important to avoid bursting and squeezing it yourself, as this generally does not result in a thorough cleaning.
