title: Detection of colorectal cancer.
abstract: In a series of 47 patients with colorectal cancer, early-stage lesions were detected more frequently on routine screening than on symptomatic screening. Signs and symptoms tended to occur in combination rather than singly. Guaiac positivity was the sole sign in only one patient. Physicians must consider the possibility of colorectal cancer in patients with suggestive signs or symptoms.
