How long do sebaceous cysts last?

Answered by Douglas Hiatt

Sebaceous cysts are typically benign growths that develop beneath the skin. They are usually filled with a combination of oil and dead skin cells called sebum. The duration of sebaceous cysts can vary depending on various factors, including their size, location, and whether or not they become inflamed.

In general, sebaceous cysts can last for an extended period of time if left untreated. They may persist for months or even years without causing any significant problems. However, it is important to note that not all sebaceous cysts require intervention or treatment.

If a sebaceous cyst becomes inflamed, it may appear red, swollen, and tender to the touch. This inflammation is often caused by an increase in sebum production or blockage of the cyst’s opening, leading to a build-up of pressure. Inflamed sebaceous cysts can be painful and may require medical attention.

In cases where the sebaceous cyst is not infected, it is generally recommended to allow for a minimum of 4 weeks for the inflammation to subside before considering any surgical intervention, such as excision. This waiting period allows the body’s natural healing processes to take place and the cyst to potentially resolve on its own.

During this time, the use of warm compresses and over-the-counter pain relievers can help alleviate symptoms and promote healing. It is important to avoid squeezing or popping the cyst, as this can lead to further inflammation or potential infection.

If the sebaceous cyst does not improve or worsens after the 4-week waiting period, or if it becomes infected, medical intervention may be necessary. In such cases, a healthcare professional may recommend drainage of the cyst or excision to remove it completely.

It is worth noting that sebaceous cysts can recur even after successful treatment. This is because the cyst wall may not be entirely removed during excision, allowing for regrowth. Additionally, the underlying causes of sebaceous cyst formation, such as excessive sebum production or blockage of the hair follicles, may still be present.

The duration of sebaceous cysts can vary, and it largely depends on factors such as inflammation, infection, and individual characteristics. While some sebaceous cysts may resolve on their own over time, it is important to seek medical advice if the cyst becomes inflamed, infected, or does not improve after a waiting period of 4 weeks.
