A cyst is a small, sac-like lump that can form under the skin or inside the body. Most are harmless, but they can sometimes become swollen, red, and painful. The most common type on the skin is called an epidermoid cyst, which develops when skin cells grow inward instead of shedding normally. These cells collect and form a soft sac filled with keratin.
Causes
Cysts can form due to blocked pores, infections, or injury to the skin. In some cases, they may also be linked to genetic conditions.
Symptoms
-
A round, smooth lump under the skin
-
Swelling or redness if infected
-
Pain or tenderness in severe cases
-
Sometimes a foul-smelling discharge if the cyst bursts
Treatment
Small, harmless cysts may not need treatment. However, if they grow, become painful, or get infected, a doctor can drain or surgically remove them. It’s best not to squeeze or pop a cyst at home because this can worsen infection and leave scars.
Prevention
While cysts can’t always be prevented, keeping the skin clean, avoiding unnecessary squeezing of pimples, and seeking early treatment for skin infections may help lower the risk.
Most cysts are not dangerous, but paying attention to changes in the skin and consulting a healthcare professional ensures safe and quick recovery.
