An abnormal and usually harmless lump or swelling, filled with fluid or semi-solid material. Cysts occur in body organs or tissue. Types of cysts include sebaceous cysts, dermoid cysts, ovarian cysts, breast cysts, Baker’s cysts, and cysts that form around parasites in diseases such as hydatid disease or amoebiasis. Cysts may need to be removed surgically if they disrupt the function of tissues.
