A cyst is a sac-like structure filled with fluid or a semisolid material that appears like a bump or a blister. A cyst is not a normal part of the body and can refer to any type of bag or sac in the body that is not typically a part of that organ or structure. They occur within your body’s tissue in any body part. Sizes range from microscopic to large cysts the size of you internal organs. Cysts are sometimes grouped together with abscesses though these are two different structures, even though they sometimes resemble the same thing.
Causes of Cysts
Cysts are caused by a variety of medical conditions including tumors, genetic conditions, infections, defect in the body’s cells, a fault in the organ of a developing embryo, chronic inflammatory conditions, parasites, an impact injury that breaks a blood vessel, or a blockage of ducts in the person’s body which then causes a fluid buildup and leads to a cyst. These and other conditions can cause two different types of cysts; benign and malignant. Most cysts are benign and not cancerous and are merely from plugged ducts. However some are considered tumors and therefore may be cancerous. These include dermoid cysts and keratocysts.
Symptoms of Cysts
The symptoms of cysts, aside from the cyst themselves, are varied. Some people notice a cyst when it occurs on the outside of their body is significant in size; these may appear like a raised portion of skin similar to a bump or a blister. It may also have some redness or swelling in that area. Most cysts are painless, though some can be painful, such as those in the breasts. Other symptoms include fever, headaches, or infertility. Most internal cysts are not known until an ultrasound, MRI scan or CT scan is performed.
Treatment for cysts vary widely based on the size, location, discomfort or pain it’s causing, the type of cyst, and how severe it is. Large cysts will need to be surgically removed, whether externally or internally. Some cysts are first drained using a needle or catheter in the cavity. If it can’t be accessed easily enough to drain, it may take radiological imaging. Occasionally, the fluid that is drained from the cyst is tested to find out if cancerous cells are present. Many cysts are caused by an underlying condition in which that condition will be treated with ultimately reduces the size of the cyst or causes it to disappear.
Types of Cysts
There are many different types of cysts, each of which can be a different size, location, cause, treatment and severity. The types of cysts include an acne cyst, arachnoid cyst, baker’s cyst, bartholin’s cyst, breast cyst, chalazion cyst, colloid cyst, dentigerous cyst, ganglion cyst, epididymal cyst, dermoid cyst, hydatid cyst, ovarian cyst, pancreatic cyst, periapical cyst, pillar cyst, pilonidal cyst, renal cyst, pineal gland cyst, sebaceous cyst, tarlov cyst, or vocal fold cyst,
