Ovarian cancer is a common cause of cancer death in women claiming the lives of over 1,00,000 women per year. The cancer occurs more commonly in women older than 50 years although it can affect younger women. The exact cause of ovarian cancer is not known. Normally, cells grow and divide in an orderly way to form new cells as the body needs them (the old cells die, and new cells take their place). Cancers are formed when the cells, (the building blocks that make up tissues) do not divide and grow in an orderly manner. So more cells than are needed are formed, and these extra cells form a mass of tissue called a growth or tumour. Cancer cells can invade that is spread to other parts of the body through the blood and lymph systems. Ovarian tumours can be benign or malignant. [Read: How Does Ovarian Cancer Affect the Body?]
