Cyst contains fluid, gas, or semisolid material
Answer: Option A

An abnormal sac containing fluid, gas or semisolid material is called as a cyst. This sac may sometime be a benign or malignant. The cyst occurs in any part of the tissue. It is normally caused if any blockage happens or by infections.
Most cysts do not have any signs. They are mostly identified by the physical observation seen as a lump or bump. They are not painful. But in certain cases where the lump is big and it stands in the way of the body functioning at once signals of pain is caused so as to drag the attention. All cysts does not necessarily need to be operated and removed. A cyst that hinders the internal organs would be removed by surgery.
