Sebaceous cysts are benign proliferations that occur due to an over-secretion of local sebaceous glands mixed with bacterial infection. Generally, they can appear on any part of the skin. Although benign, if left untreated, they tend to grow larger. Typically, surgical removal is curative if the cyst sac is completely excised, with recurrence usually due to incomplete removal of the cyst sac or new flare-ups at other sites due to inflammation and infection. Once the condition is adequately treated, it is crucial to adopt a standardized diet and lifestyle habits. Try to avoid greasy and spicy foods, enhance physical exercise, sweat more, and avoid bathing or swimming in public pools, as well as keeping pets.
