Question

what is cyst ?Explain it briefly..

Answer 1

Cysts are usually noncancerous and have a sac-like structure that can contain fluid, pus, or gas. Cysts are common and can occur anywhere on the body. Cysts are often caused by infection, clogging of sebaceous glands, or around earrings.
Many cysts do not cause any symptoms and go away on their own. Cysts can come back. Draining or surgically removing cysts usually has no complications or side effects. In rare cases in which a cyst is next to or inside a cancerous tissue, the prognosis depends on the type of cancer and whether it has spread.

In simple language you can say that :-
a swelling or a lump filled with liquid in the body or under the skin is known as cyst.
