Cysts

Cysts are closed sac-like or capsule structures that may be filled with liquid, semisolid, or gaseous material. They are not a part of the normal tissue where they are located. They have a distinct membrane and are separated from nearby tissue. The size of cysts can vary from microscopic to very large. The symptoms, treatment, and prognosis of cysts depend on their type and location.

Types of Cysts

There are hundreds of different types of cysts. Some of the most common types include:

• Sebaceous cyst: These are small, noncancerous cysts that commonly appear on the skin.
• Ovarian cyst: These are fluid-filled sacs that develop on the ovaries.
• Breast cyst: These are fluid-filled sacs that develop in the breast tissue.
• Kidney cyst: These are fluid-filled sacs that develop in the kidneys.
• Baker's cyst: This is a fluid-filled cyst that causes a bulge at the back of the knee.

Causes

Cysts can be caused by:

• Infections
• Genetic conditions
• Chronic inflammatory conditions
• Blockages in ducts
• Parasites
• Injuries that break vessels

Symptoms

The symptoms of cysts depend on their type and location. Some cysts may not cause any symptoms and are discovered during a physical examination or imaging study. Other cysts may cause symptoms related to their location and size.

Treatment

The treatment of cysts also depends on their type, size, and location. Some cysts may not require treatment if they are not causing symptoms. Other cysts may require surgical removal or other types of treatment.

Prognosis

The prognosis of cysts depends on their type, size, location, and whether they are benign or malignant.
