One red flag by itself is not enough to get concerned, but three or more and you need to DEMAND a thorough examination with a CT scan or MRI as they may indicate serious disease or pathology.
Here are some of the most common red flags:
1. Unexplained weight lost.
2. Night pain with or without night sweets.
3. Pain that does NOT respond to movement.
4. Family history of cancer or suspected disease.
