I have two non-healing ulcers on my leg. could this indicate cancer of some sort?

Leg Ulcers: The short answer is yes, they could. Cancers can eventually present as ulcers by the time they are noticed by the patient or by the time you make it to the physician. You should have these 'ulcerations' evaluated by your physician so they can direct you to the appropriate subspecialist.

Neeed for medical-ex: You need a medical examination by a physician. Non healing Ulcers can be caused by poor circulation or neuropathies. So you need to get checked for diabetes and for varicose veins and vascular insufficiency which will require a compelte medical examination
