could a diadnosis of RA be mistaken for a form of cancer
Rheumatoid arthritis usually presents with joint damage and pain. Often the hands and fingers are affected. Rheumatoid factor is often elevated. X-rays can help tell if the changes are characteristic.
Cancers usually present with tumors. Blood cancers can present with changes in the blood counts. Cancers can involve the bones and create dense spots or weak spots but they would look very different from rheumatoid arthritis on an x-ray. I don't think I've ever seen a cancer show up as joint problems so I don't think RA and cancer would be confused.
