Is dark spot appearing on bones by bone scan cancer?

Could be...: ...But bone scans can be non specific and other events happening in the bone (even arthritis or old fractures) can show up too. Needs to be put in context. Why was it done? Any symptoms? Do you have already been diagnosed with cancer? Old trauma? Whosoever ordered that test needs to sit with you and go over its implications and what else to do. Best to you.

No: A dark spot on a bone scan simply represents increased bone turnover. This can occur in many circumstances and can represent things such as degenerative disease, fracture, or cancer. More important than if a spot is dark is where the dark spot is located and the specific patient history.

Not necessarily: A dark spot only indicates that there is increased activity at that site. Cancer can cause this finding, but so can benign tumors, fractures and infections.

Maybe not: Areas if increased uptake can be caused by a number of different things. Fractures can do this as well as arthritis (if near a joint), infection and yes cancer can do this also...But other bone lesions that are not considered malignant can also do this. This is why it is so important to see your doctor, who can put this information together with your history, symptoms and results from other tests.
