Knee pain? It could mean something worse than you think

According to new research smokers need to be especially conscious of knee pain, as it could be an early indicator of lung cancer. In a small study looking at patients with both knee inflammation and pain, a small percentage (only 2%) were also found to have non-small cell lung cancer. Now that may sound like an extremely small number, but consider this: of that 2% that had both knee pain and cancer all of them were smokers.

Non-small cell lung cancer is very difficult to treat unless it's caught in the early stages, so getting this clue that knee pain could be an indicator could really help save lives.
