An ulcerating cancer wound is when a cancer that is growing under the skin breaks through the skin and creates a wound. Doctors sometimes call them fungating cancer wounds. It can be a distressing problem to cope with. But there are different treatments and ways to manage the symptoms.
When the cancer grows, it blocks and damages tiny blood vessels. This can reduce the supply of oxygen to the area. This causes the skin and the tissue underneath to die, and the wound may become infected and ulcerated.
Ulcerating wounds are rare. Most people with cancer will never develop one. It is more likely to happen in breast cancer, head and neck cancer and melanoma. This is because these cancers develop close to or on the skin.
An ulcerating wound can develop in the area where the cancer started (primary site) or a part of the body the cancer has spread to (secondary site).
