10 Common Types of Cysts
A cyst refers to a closed sac where there is a distinct membrane with possible division when compared to the nearby tissue. One of the characteristics of a cyst is the formation of a “shell” or “capsule” which is abnormal when compared with the surrounding cells. The cyst can contain fluids, semi-solid material or air. It should be noted that a collection of a pus is known as an abscess and should not be referred to as a cyst. Once it has formed, it may resolve on its own or may be removed surgically. It is believed that cancer-related cysts are the body’s attempts as a defense mechanism for the body.
Once mutations occur, they may result in uncontrolled cellular division resulting in the formation of a tumor. The body then tries to encapsulate these cells to prevent division and growth of a tumor, which is known as a cyst. However, the cells can mutate further while gaining the ability of forming their own blood vessels which nourish them and play a crucial role in their growth and development. Once that occurs, the capsule loses its function and the tumor may proceed from being benign to invasive.
