A sebaceous cyst is a small, benign growth that typically appears on the skin as a round, firm bump. These cysts are filled with a substance called sebum, which is produced by the sebaceous glands in the skin.

Sebaceous cysts are common and can occur anywhere on the body, but they are most often found on the face, neck, and torso. They can range in size from a pea to a golf ball and are usually painless, although they can sometimes become tender or inflamed.

Sebaceous cysts are typically caused by clogged pores or hair follicles. They can also be caused by injuries or trauma to the skin, such as cuts, bites, or punctures. In some cases, sebaceous cysts may be hereditary or caused by a condition such as acne or skin cancer.

Sebaceous cysts are generally harmless and do not require treatment. However, if a cyst becomes infected or inflamed, it may need to be drained or removed by a healthcare provider.

To prevent sebaceous cysts from forming, it’s important to maintain good skin hygiene by washing regularly and avoiding harsh or drying skin products. It’s also important to avoid squeezing or picking at pimples or other skin growths, as this can lead to infection and the formation of sebaceous cysts.

In conclusion, sebaceous cysts are common, harmless growths that typically appear on the skin as firm, round bumps. While they do not usually require treatment, it’s important to maintain good skin hygiene and avoid squeezing or picking at pimples to prevent them from forming.
