This simple test could warn you of lung cancer

An oncology nurse adviser is urging people to be on the lookout for “finger clubbing” as it could be a sign of lung cancer. There’s a simple test you can do to spot it, says Bupa UK’s Emma Norton. It’s called the Schamroth window test and involves putting your nails together to see if there’s a diamond-shaped space between your cuticles. If there isn’t a space, this is a sign of finger clubbing.
