Ovarian cyst is a fluid or semi fluid filled sac in the ovary. There are many types of ovarian cysts and they are categorized below:

Follicular Cyst

Follicular Cyst is the commonest ovarian cyst. This is a normal development in an ovulatory cycle. After ovulation, the cyst will become a corpus luteal cyst. If pregnancy doesn’t occur, the corpus luteal cyst will resolve and disappears. These cysts are usually asymptomatic. However, some women do experience some ‘mid-cycle’ pain around ovulation. Occasionally the corpus luteal rupture can rupture and cause bleeding in the abdomen.

Benign Ovarian Cysts (Non Cancerous Cysts)

Endometriotic cyst
These cysts are filled with brownish stale blood and are also called ‘chocolate cysts’. They are usually associated with endometriotic spots in the pelvis and sometime, pelvic adhesions. Endometriosis can cause infertility, pain during menses, pain on defecation and painful sexual intercourse.

Benign Ovarian Cysts (Non Cancerous Cysts)

Dermoid cyst
Dermoid cysts are filled with thick yellow fluid, sebum. Structures such as skin tissues, hair, teeth, brain tissues can also be present.
Mucinous cyst and serous cyst
These cysts are filled with mucoid and watery clear serous fluid respectively

Malignant Cyst (Cancerous Cyst)

Usually these cysts also do not present with symptoms until at a late stage. These cysts may be multiseptated with some solid areas. Ascites (fluid in the abdomen) may be present. CT Scan assessment is needed
