No: Upper endoscopy is needed. Colonoscopy looks for cancer or other disease in the colon. To check for stomach cancer the endoscope needs to be inserted through the mouth for visualization of stomach.

Cannot: Cancer spreading is usually determined by biopsies at the tine of surgery. Some radiology tests could suggest concerns of spread such as ct scan or pet scan, but biopsies are the only way to tell definitively.
