Cysts have many causes, and common ones include tumors, cellular defects, errors in embryonic development and blockages of ducts in the body. Some cysts contain malignant cells, but most of them are benign, according to MedicineNet.
Cysts are capsule structures that are filled with liquid, gaseous material or semisolid material and occur within body tissues. They occur in varying sizes and can appear in any part of the body, notes Medical News Today. Some cysts develop deep in the body where they cannot be seen. Most of them are painless, have smooth surfaces and grow slowly, explains Healthline.
The risk factors for cyst development depend on the causes. The primary ones include genetic conditions, infections, defects in developing organs, and any material that prevents the smooth flow of oils or fluid in the body, says MedicineNet.
Some cysts, particularly those found in the liver or kidney have no symptoms. Sometimes, these capsules are felt by touching as a bump or lump under the skin and can be painful. Examples of noticeable cysts are those found in the mammary glands, according to Medical News Today.
A red or painful cyst is an indication of an infection or rupture. In such cases, patients should seek medical attention immediately. Doctors advise their patients to have regular checks on cysts or abdominal growths, to reduce the development of severe conditions such as cancer, states Healthline.
