What Is a Sebaceous Cyst, and When Should It Be Removed?

Question

I recently noticed a small, painless lump under my skin, and after some research, I suspect it might be a sebaceous cyst. I want to understand what causes these cysts, whether they are harmful, and how to treat them. Some people say that sebaceous cysts go away on their own, but I am unsure whether they can get infected or grow larger over time.

A sebaceous cyst is a noncancerous lump filled with keratin, formed due to blocked sebaceous glands. They often appear on the scalp, face, neck, or back, and while they are usually harmless, they can become painful, red, or infected. Many dermatologists recommend warm compresses to encourage drainage or minor surgery for removal. However, I want to know whether home remedies like tea tree oil or aloe vera can help in shrinking cysts naturally.

For those who have had sebaceous cysts, what treatments worked best for preventing infections and avoiding surgical removal?

Would love insights into how to differentiate between harmless cysts and those that require medical attention.

Dr. Harsha Joy · Accepted Answer

In Ayurveda, sebaceous cysts are seen as a result of an accumulation of toxins (ama) in the body that leads to blockages, particularly in the body's channels (srotas) that govern oil and waste elimination. These cysts are usually noncancerous and occur when sebaceous glands become blocked, trapping keratin or oil under the skin. They can appear on areas like the scalp, face, neck, or back. While sebaceous cysts are typically harmless, they can become inflamed, infected, or grow larger over time, especially if irritated or if the drainage is blocked. Ayurvedic treatments often focus on clearing blockages through gentle detoxification methods, such as using cooling herbs like aloe vera or turmeric to reduce inflammation. Tea tree oil, known for its antibacterial properties, may help prevent infection if applied topically, but it’s important not to puncture or try to drain the cyst at home, as this could lead to infection. If a sebaceous cyst becomes painful, red, or starts growing rapidly, it is important to consult with a healthcare provider. In many cases, a warm compress can encourage drainage and relieve discomfort, but surgical removal may be necessary if the cyst does not shrink or if it becomes recurrent. Differentiating between harmless cysts and those requiring medical attention comes down to changes in size, pain, redness, or signs of infection. If any of these occur, it’s important to seek medical advice to prevent further complications.

Dr Sujal Patil · Answer

Sebaceous cysts are noncancerous lumps that form when sebaceous glands become blocked, leading to a buildup of keratin. They are typically small, painless, and slow-growing, but they can become inflamed or infected, causing redness, tenderness, and discomfort. While many cysts remain harmless and may resolve on their own, infected cysts often require medical attention.

Applying warm compresses can promote drainage and reduce swelling, but complete removal often requires minor surgery. Tea tree oil may help reduce bacteria and inflammation, but there is limited evidence on its effectiveness for shrinking cysts. Aloe vera may soothe irritation but won’t dissolve the cyst. If the cyst grows, becomes painful, or shows signs of infection, it’s best to see a doctor.
