Questions about the treatment of sebaceous cysts?

Can a sebaceous cyst disappear and then reappear? I had one that disappeared but has recently come back.
Is it possible to treat it with laser therapy instead of surgery if its diameter is less than 2mm?

If it's not too large, it can be done, but it must be assessed on-site.

More Info

Lipomas, commonly known as fatty tumors, are benign growths composed of adipose (fat) tissue. They are generally soft, movable, and painless, and can occur anywhere on the body. One of the common questions regarding lipomas is whether they can disappear and then reappear.
To address your question, lipomas do not typically "disappear" in the sense that they shrink and then grow back. However, it is possible for a lipoma to be mistaken for another type of growth or for a small lipoma to be undetected initially. In some cases, if a lipoma is removed, new lipomas may develop in different areas of the body, as some individuals are predisposed to developing multiple lipomas due to genetic factors.
Regarding treatment options, laser treatment for lipomas is not commonly practiced. The most effective and definitive treatment for lipomas is surgical excision, where the lipoma is completely removed. This method ensures that the lipoma does not return in the same location. While there are various non-surgical methods, such as liposuction, these may not be as effective in completely removing the lipoma and could lead to recurrence.

In terms of laser treatment, while lasers can be used for various skin conditions, they are not typically used for lipomas. The reason is that lasers target specific skin layers and conditions, and lipomas are deeper, subcutaneous structures that require complete removal to prevent recurrence.
If you have a lipoma that is less than 2mm in diameter and you are considering treatment, it is essential to consult with a dermatologist or a surgeon who specializes in skin lesions. They can provide you with the best advice based on the specific characteristics of your lipoma and your overall health.
In summary, while lipomas do not usually disappear and then reappear, new lipomas can form in predisposed individuals. Surgical excision remains the gold standard for treatment, and laser treatment is not typically recommended for lipomas. If you have concerns about a lipoma or its treatment, seeking professional medical advice is crucial for appropriate management.
