The womb (uterus)
The womb (uterus) is a muscular, pear-shaped organ where a baby is carried during pregnancy.
It sits low in the pelvis (the area between the hips) and is supported by the pelvic floor muscles. The lower part of the womb is called the cervix.
The cervix is joined to the top of the vagina and is sometimes called the neck of the womb. Cancers that start in the cervix behave differently and are treated differently from womb cancer.
The lymphatic system
The lymphatic system is part of the immune system - the body’s natural defence against infection and disease. The lymphatic system has two main roles: it helps to protect the body from infection and it drains fluid from the tissues. It’s made up of organs such as bone marrow, the thymus, the spleen, and lymph nodes. The lymph nodes throughout the body are connected by a network of tiny lymphatic tubes (ducts).
The pelvic lymph nodes are the most likely to be affected by cancer of the womb.
