Can a normal x-ray of the back and chest show if a melanoma has spread?

Sometimes: A chest xray can show nodules in the chest and is used as part of follow-up. The ct scan and the pet scan are more specific tests when metastasis is suspected. For follow up after initial surgery the nccn has an excellent guide for patients. It helps to decide what tests are appropriate and what ones are not needed. We don't want to over irradiate people in follow-up.

Possibly: A chest x-ray can pick up a mass if large enough. A back x-ray may not unless there is obvious bone involvement. Hope this helps.

No usually: An x-ray generally is not sensitive to find this out. My patients who are at high risk for metastatic melanoma undergo a ct scan, a brain mri, and a pet scan.
