Nobody knows: I don't know what it is- it could be many things. If possible, a biopsy or surgical procedure to remove it should be done - especially if there are symptoms related to it- i.e. Bleeding etc.
Dr. Douglas Tisdale
Medical Oncology 35 years experience
Needs a biopsy: The duodenum is not a common site of cancer, nor of nodules, except in certain cancer-predisposed families. The prognosis for an individual becomes clearer once the tissue has been examined under the microscope, since a nodule could be non-malignant, pre-cancerous, or cancer. Usually an upper endoscopy is required.
Dr. William Mitchell
Pathology 61 years experience
Unlikely: Cancer of the duodenum is rare.
