Popping the Mystery of Cysts: What You Need to Know

Cysts are a common dermatological concern that can appear anywhere on the body. While they are usually harmless, they may inflame and cause significant discomfort.

What Is a Cyst?

A cyst is a sac-like pocket of tissue that can be filled with fluid, air, or other material. These growths can form just beneath the skin or deeper within the body. Although cysts can appear in various sizes, many are small and go unnoticed unless they become inflamed or infected. While most cysts are benign, they can sometimes be uncomfortable or cause aesthetic concerns.

What Causes Cysts to Form?

Cysts form when a hair follicle or a gland becomes clogged, irritated, or inflamed. This leads to a buildup of fluid or other substances inside the cyst. The following factors are common causes of cyst formation:

  • Blocked Hair Follicles: When hair follicles are obstructed, sebum (oil) and dead skin cells can accumulate inside, creating a cyst.
  • Ingrown Hairs: Hairs that grow back into the skin can cause inflammation and lead to cysts, especially in areas that are frequently shaved.
  • Skin Inflammation: Conditions that cause skin irritation or inflammation can increase the likelihood of cyst formation, as the body’s natural response is to trap substances within the skin.

Are There Different Types of Cysts?

Yes, cysts can vary in type and appearance. Here are a few of the most common:

Epidermal Cysts: These are the most common type of cysts found on the skin’s surface. They often develop from hair follicles or sweat glands and typically have a small, visible opening.

Pilar Cysts: Pilar cysts tend to form deeper within the skin and are more commonly found on the scalp. They are firmer to the touch and are usually hair follicle-related.

Sebaceous Cysts: These cysts form from sebaceous glands, which are responsible for producing oil that keeps the skin moist. When these glands become blocked, sebaceous cysts can develop.

Are Cysts Cancerous?

In general, cysts are not cancerous. However, some cysts may appear suspicious, and it’s important to have them evaluated by a dermatologist to rule out any potential malignancy. While most cysts are benign, a doctor may recommend removal if the cyst appears irregular or if it is causing significant discomfort.

What Are the Common Symptoms of a Cyst?

Cysts are typically small, round, and firm to the touch, but their appearance and texture can vary depending on the type. In some cases, cysts may become red, swollen, or tender to the touch, especially if infected.

Home Remedies for Cysts

While many cysts do not require immediate medical treatment, you can try a few home remedies to manage mild cases.

  • Warm Compresses: Applying a warm compress to the cyst can help reduce swelling and encourage the cyst to drain on its own. Make sure the compress is not too hot to avoid burning the skin.
  • Cold Compresses: Cold packs can help reduce pain or inflammation around the cyst.
  • What NOT to Do: Never try to pop or squeeze a cyst. Doing so can spread bacteria and cause further inflammation, leading to complications such as infection or abscess formation.

Are There Risks to Using Home Remedies?

Yes, there are risks associated with using home remedies for cysts. Applying pressure or squeezing a cyst can cause it to rupture, which may lead to increased inflammation or infection. In severe cases, untreated or improperly handled cysts can develop into more serious conditions, including sepsis—a life-threatening infection that requires immediate medical attention.

Medical Treatments for Cysts

If a cyst becomes infected or is causing significant discomfort, medical intervention may be necessary.

Common treatments include:

  • Antibiotics: If a cyst is infected, a dermatologist may prescribe antibiotics to treat the infection and prevent it from spreading.
  • Steroid Injections: These can help reduce inflammation in the cyst and shrink it over time.
  • Drainage: In some cases, a dermatologist may need to drain the cyst to relieve pressure or remove its contents. This is done under sterile conditions to avoid infection.
  • Excision: The most radical intervention, is when the cyst is removed completely with the sac. Although this intervention helps to get rid of the cyst completely it is essentially a small surgery. And as any surgery it may have more complications such as scarring, poor healing and wound infection.

Can Cysts Go Away?

In many cases, cysts may resolve on their own over time, especially if they are small and do not become infected. However, some cysts may persist or enlarge, leading to scarring or other complications. While they may not always go away without treatment, many cysts can be managed effectively with proper care.

Cyst vs. Lipoma – How Do They Differ?

Though they may appear similar, cysts and lipomas are distinct in several key ways. Lipomas are benign fatty tumors that feel soft and rubbery. They are usually deeper within the skin and are made of fatty tissue, not fluid. While both cysts and lipomas are generally non-cancerous, lipomas are usually slower-growing and are less likely to become infected than cysts.

When Is Medical Intervention Necessary?

You should seek medical attention if you notice any of the following signs with your cyst:

  • Tenderness: If a cyst becomes painful or inflamed, it may develop bacterial infection, and may require professional treatment.
  • Pus or Fluid: If the cyst appears to be filled with pus or fluid, it may be infected and should be examined by a doctor.
  • Changes in Size: Rapid growth or a sudden change in appearance could indicate an issue that requires medical evaluation.

How to Prevent a Cyst Formation

While not all cysts can be prevented, there are a few steps you can take to reduce the likelihood of developing one.

  • If you frequently shave, ensure you are using correct techniques to avoid ingrown hairs, a common cause of cysts.
  • Using gentle antibacterial cleansers can help prevent the buildup of oils and dead skin cells in hair follicles.
  • Certain skin conditions, such as acne or hidradenitis suppurativa, can make cysts more likely. If you have a chronic skin condition, it’s essential to work with a dermatologist to manage it effectively.
