I have 5 swollen lymph nodes went to doc they said they feel fine but will do a cheat x ray just to check will this show anything or indicate the nodes aren't cancerous?

The diagnosis of cancer requires a tissue diagnosis and is not an X-Ray diagnosis even though the X-Ray can be very suggestive. In your case, you don't mention where your enlarged nodes are & a normal chest X-Ray may only rule out lung pathology. Did you have any blood tests like a cbc& differential cell count.and a monotest? If these are normal& there are no symptoms, we usually recheck in 2 week

No, the chest X-ray may only suggest lung pathology through abnormal lung findings and/or enlarged lymph nodes in the chest, by no means expected to be diagnostic. All findings will need a proper clinical context to be interpreted correctly.

Chest x-ray by itself not indicate cancer or not, but if lymph nodes in your chest are also enlarged, that would warrant a more invasive diagnostic test, e.g., removal of a lymph node for examination by a pathologist. Wish you good health!
