If the cyst is very unusual, your doctor may prescribe some additional tests to rule out possible cancers. You may also need these tests if you wish to have the cyst surgically removed.
Common tests used to test these sebaceous cysts include:
- CT scans, which guide to thebest route for surgery and spot abnormalities

- punch biopsy, which involves removing a small amount of tissue from the cyst to be examined in a laboratory for the signs of cancer
Your dermatologist can treat a sebaceous cyst by draining it or by surgically removing it. Normally, the cysts are not so dangerous but they are removed for cosmetic reasons. Since most of the cysts are not much harmful to your health, your doctor will allow you to choose the sebaceous cyst treatment option that works for you.

Here are some of the common methods your doctor may use to remove your cyst:
- Conventional wide excision: Completely removes a cyst but usually leavesa long scar
- Minimal excision: Causes minimal scarring but there are chancesthat the cyst will return
- Laser with punch biopsy excision: In this method, laser is used to make a small hole to drainthe contents in the cyst and the outer walls of the cyst are removed about a month later
Once the cyst is removed, your doctor may prescribe an antibiotic ointment to prevent infection. This should be used until the healing process is complete. Your doctor may also recommend a scar cream to reduce the appearance of any surgical scars.
Most cysts are normally not cancerous. Ones left untreated can become very large and may eventually require a surgical removal if they become quite painful or uncomfortable.
If you undergo a complete surgical removal treatment, the cyst will most likely not return in the future.
In rare cases, the area where the cyst is removed may become infected. In this case, contact your doctor if your skin shows any signs of infection such as redness and pain or if you develop a fever. Though most of the infections get recovered with antibiotics, but some can be deadly if untreated.
