What Is Uterine Cancer?
Uterine cancer, also known as endometrial cancer, is the abnormal growth of any cells that originate from the endometrium, the inner lining of the uterus (womb). These abnormal cells grow uncontrollably, forming a mass called a tumour. Uterine cancer is the fourth most common cancer diagnosed in females in Singapore.*
Certain tumours of the uterus can however be benign, such as a fibroid, a polyp, or endometriosis. These are usually not life-threatening and can be treated or removed. They do not invade neighbouring tissues or spread to other parts of the body.
Malignant growths, which are cancerous, can invade nearby tissues and organs such as the vagina and spread to other parts of the body. The cancer cells break out of the uterine tumour and travel via lymph vessels to nearby lymph nodes. They can also spread through the blood vessels to other organs such as the lung, liver, or brain, forming tumours in these new locations.
