Ovarian cancer | What is Ovarian cancer?
In ovarian cancer, cells in your ovaries start to grow abnormally and out of control.
Ovarian cancer can sometimes spread more widely in your abdomen (tummy) or more rarely, to other organs through your bloodstream or lymphatic system. The lymphatic system is the tissues and organs, including your bone marrow, spleen, thymus, and lymph nodes, that produce and store cells that fight infection and disease. The channels that carry lymph are also part of this system. If ovarian cancer spreads to other parts of your body, it can form secondary tumours. The spread of cancer through your body is called metastasis.
