15. Swollen Lymph Nodes
In addition to the liver, colon cancer can also spread to the lymph nodes. Located throughout the body in areas like the neck, armpit, and groin, lymph nodes are “…part of a system of tubes and glands in the body that filters body fluid and fights infection,” says Cancer Research UK.
Because a build up of cancer cells can prevent lymph fluid from draining through the blood as it normally would, the lymph nodes tend to become swollen or hard. This can lead to what’s known as lymphedema, which is most commonly characterized by fluid retention and swelling in the area of the affected lymph nodes.
