Ulcerating cancers (fungating wounds)
A fungating tumour can start as a shiny, red lump on the skin.
If the lump breaks down, it will look like a sore. The wound will often get bigger without any treatment. It can spread into surrounding skin or grow deeper into the skin and form holes.
The skin around the wound may look red and blistered. Pieces of dead skin (tissue) can sometimes fall off.
You might have other symptoms, such as:
a strong, unpleasant smell from the wound
itching
oozing from the wound – this may be pus or clear fluid
pain where the wound is
pain elsewhere in the body from the wound pressing on nerves
bleeding (including from the skin around the wound)
You might feel scared or embarrassed about going to your doctor or nurse. Or you might feel frightened of what they would say the problem is.
These feelings are normal and understandable. But the sooner a doctor treats the wound, the easier it is to control and the less effect it will have on your life.
See your doctor as soon as possible if you think you might have an ulcerating tumour. Or you could see your practice nurse, nurse practitioner or symptom control nurse.
