Sometimes: Mris can show cancer in the brain, spinal cord, liver, muscle, and breast. . But mris aren't usually done to "screen" for cancer. The MRI must be done with certain dyes (called contrast agents) to look for cancer. If you had an MRI for another reason, and you are wondering if it would have shown cancer, ask your doctor. It depends on how the test was done and whether contrast was given.

Depends: Mri is very good at showing abnormal tissue from normal tissues and can pick up various cancers very well. Some cancers, however, can be small and not well seen on mri. Some may be better seen on ct. Cancers involve in the stomach and colon are usually not well seen and may require endoscopy or colonscopy. Some breast cancers are also better seen on mammograms than mri.
