U.S.: If you’re a smoker, you should get a piss test. Trust us.
- Your urine may predict your lung cancer risk. Sort of like a drug test in reverse, there’s a chance that doctors will be able to predict the onset of lung cancer early thanks to your urine. Two chemicals, NNAL and cotinine, show up in higher levels for people with a high lung-cancer risk, and knowing this early can help doctors treat or prevent lung cancer before it becomes something life-threatening. It’ll take some time for the test to come on the market, but here’s a tip in advance – make sure you haven’t also been smoking pot when you get the test – doctors can tell that, too. source
