Are Cysts Cancerous? What You Should Know

At Long Island Medical & Cosmetic Dermatology, Dr. Daniel Sherer provides comprehensive dermatology care for patients across Huntington, Hicksville, Syosset, and Plainview, NY. Many individuals visit the office with concerns about cysts, often wondering whether these growths could be cancerous. Understanding what cysts are, how they form, and when they may require evaluation helps patients feel more confident about their skin health.

What Exactly Is a Cyst?

A cyst is a small pocket beneath the skin that contains keratin, oil, or fluid. Many forms occur when a hair follicle becomes blocked or irritated, and in some cases, minor injury can contribute. The most common types are epidermal and pilar cysts, which often feel like firm, round bumps. They may swell or feel tender at times, but they are usually harmless. Because other skin conditions can resemble cysts, a dermatologic evaluation helps confirm the diagnosis.

Are Cysts Cancerous?

Cysts are rarely associated with cancer. Their appearance and texture typically differ from growths that raise more serious concerns. Even so, any new lump on the skin should be examined if it grows quickly, changes shape, becomes painful, or behaves differently than expected. A dermatologist can assess the area with a physical exam and, if needed, take a small sample for testing. Early evaluation provides reassurance and ensures appropriate care when necessary.

Treatment Options for Cysts

Some cysts require no treatment if they remain stable and do not cause discomfort. When a cyst becomes irritated, warm compresses or topical treatments may help ease soreness. For cysts that repeatedly swell, become infected, or continue to enlarge, removal is often the most reliable option. The procedure is typically quick and performed in the office, allowing most patients to return to normal activities soon afterward.

When to Seek Dermatology Care

Any cyst that changes, causes discomfort, or interferes with daily activities should be evaluated by a dermatologist. While most cysts are harmless, proper diagnosis prevents unnecessary worry and ensures that other skin conditions are not overlooked. Dermatologists can also discuss strategies to reduce recurrence, especially for patients prone to cyst formation.
