What Are Cysts and What Does Cyst Removal Actually Involve?

If you've ever noticed a bump under your skin that seems to just... stay there, you may have wondered whether it's something to worry about. For many people, that lump turns out to be a cyst. Cysts are incredibly common, and while they're usually harmless, they can be uncomfortable, unsightly, or prone to infection. Understanding what they are and what your options look like can help you make an informed decision about your skin health.

What Exactly Is a Cyst?

A cyst is a closed, sac-like pocket of tissue that can form just about anywhere in the body, including beneath the skin. These sacs are typically filled with fluid, air, or semi-solid material. When it comes to skin cysts, you're most often looking at one of a few common types.

Epidermoid cysts (sometimes called sebaceous cysts, though that term is often used loosely) are the most common. They develop when skin cells multiply beneath the skin's surface instead of shedding normally. The result is a smooth, round bump that may have a small central opening called a punctum. They're most frequently found on the face, neck, back, and chest.

Pilar cysts form from hair follicles and tend to appear on the scalp. They're firm to the touch and can run in families.

Ganglion cysts typically show up near joints or tendons, especially on the wrist or hand. They're filled with a gel-like fluid and can change in size depending on how much you use the affected joint.

Milia are tiny, white cysts that form just under the skin's surface, often around the eyes and nose. They're common in newborns but can also affect adults.

Most cysts are benign, meaning they're not cancerous. However, any new or changing lump on the skin should be evaluated by a dermatologist to rule out anything more serious.

Why Do Cysts Form?

Cysts develop for a variety of reasons. Blocked ducts, hair follicle issues, infections, and even genetic factors can all play a role. Trauma to the skin, such as a scrape or puncture wound, can sometimes trigger a cyst to form as well. In some cases, there's no identifiable cause at all.

Because the root causes vary, so do the types of cysts. What's important to know is that cysts don't typically go away on their own. They may shrink or become less noticeable at times, but the sac itself usually remains. Without proper treatment, many cysts continue to grow slowly over time or become infected.

Signs a Cyst May Need Attention

Not every cyst requires immediate removal. Small, asymptomatic cysts that aren't bothering you can often just be monitored. That said, there are several situations where removal is worth considering.

You should see a dermatologist if your cyst is growing in size, has become painful or tender to the touch, shows signs of infection such as redness, warmth, swelling, or drainage, is in a location that causes discomfort with movement or clothing, or is affecting your confidence or quality of life. Infected cysts can become abscesses if left untreated, which can require more involved treatment. Catching and treating a cyst before it gets to that point is always the better path.

What Does Cyst Removal Involve?

One of the most common questions patients have is what they're actually signing up for when they agree to have a cyst removed. The good news is that for most skin cysts, this is a straightforward in-office procedure.

The initial evaluation is where everything starts. Your dermatologist will examine the cyst, take note of its size and location, and may ask how long it's been there and whether it's changed. In some cases, a biopsy or imaging may be recommended before removal, but for most common cysts, the examination alone is enough to determine the best approach.

Local anesthesia is used to numb the area before any procedure begins. Most patients find the injection itself to be the most uncomfortable part. Once the area is numb, you shouldn't feel pain during the removal, though you may feel some pressure or movement.

Excision is the standard method for fully removing a cyst. The dermatologist makes a small incision in the skin, removes the cyst and its entire sac, and closes the wound with sutures. It's important that the entire sac is removed, because if any part of it is left behind, the cyst is likely to come back.

Incision and drainage is a different approach sometimes used for infected cysts. The dermatologist makes a small cut to release the contents and relieve pressure. While this can provide immediate relief, it doesn't remove the sac itself, so regrowth is possible. This method is often used as a first step when infection is present, with full excision performed later once the infection has resolved.

Recovery is typically simple. You'll have a small wound with sutures that will need to be kept clean and dry for several days. Most people return to normal activities quickly. Your dermatologist will give you specific aftercare instructions and let you know when to return for suture removal, usually within one to two weeks.
