Can an ultrasound detect colon cancer?
Although not suitable as a first choice screening procedure for colorectal cancer, routine abdominal ultrasound can detect even non-suspected colonic tumors, especially in the ascending colon.

Can a CT scan detect bowel problems?

Can stress cause polyps?
This study suggests that patients who experienced total life events may be at higher risk of having colon polyps and adenomas which indicates an association between stress and the development of colorectal polyps.
Can colon polyps cause weight gain?
Colorectal adenomas are known as precursors for the majority of colorectal carcinomas. While weight gain during adulthood has been identified as a risk factor for colorectal cancer, the association is less clear for colorectal adenomas.
Can you poop out a polyp?
