If a non-healing sore is suspected to be cancerous, a healthcare provider may recommend several diagnostic tests:
Biopsy: A sample of the sore is taken and examined under a microscope to look for cancer cells. Imaging tests: X-rays, CT scans, or MRIs may be used to determine the extent of the sore and check for metastasis. Blood tests: These can help detect markers associated with certain types of cancer.
