A UK woman's decision to post a photo of her curved fingernail to social media has possibly saved her life, after it led to an astonishing cancer diagnosis.
Grandmother Jean Williams Taylor posted a photo to Facebook last week of her unusually curved fingernail, asking if anyone else had something similar.
Ms Taylor was told to visit a doctor, which she felt was a "tad extreme".

But after an examination, her doctor immediately rushed her for blood tests and a chest X-ray, which led to a lung cancer discovery.
"Two days later I got a phone call to go for a CT scan, two days later a PET scan and more blood tests," Ms Taylor wrote on Facebook.
"After a gruelling 2 weeks, yesterday I got my results... Cancer in both my lungs !!!!" she wrote.
"When your nails curve its often linked to heart and lung disease and its official term is "clubbing" I had no idea...Did You?"
Nail clubbing can happen when the tips of fingers enlarge and the nails curve. Sometimes it can be caused by low oxygen in the blood, but is also a symptom of various types of lung disease.
