Signs and Symptoms
Patients present with trouble swallowing, gastrointestinal hemorrhage or metastases (mainly in the liver). Intestinal obstruction is rare, due to the tumor's outward pattern of growth. Often, there is a history of vague abdominal pain or discomfort, and the tumor has become rather large by time the diagnosis is made.
Generally, the definitive diagnosis is made with a biopsy, which can be obtained endoscopically, percutaneously with CT or ultrasound guidance or at the time of surgery.

“Surrealism is a bourgeois disaffection; that its militants thought it universal is only one of the signs that it is typically bourgeois.”
—Susan Sontag (b. 1933)
“Murderous desire, hatred, distrust are nowadays the accompanying signs of physical illness: so thoroughly have we embodied our moral prejudices.—Perhaps cowardice and pity appear as symptoms of illness in savage ages. Perhaps even virtues might be symptoms.”
