Jean Williams Taylor posted an image of her fingernails on social media enquiring if anybody had seen anything similar before, and it turns out her curved fingernails were a sign of lung cancer.

After sharing the picture, Jean was urged to go to the doctors and after several tests, it was revealed she had cancer in both of her lungs.

Finger clubbing is the term given to Jean’s symptom and while it may be less common, it is a symptom of lung cancer. The NHS describes finger clubbing as "changes in the appearance of your fingers, such as becoming more curved or their ends becoming larger."

Jean shared her post on Facebook in the hope she could help others. She stated in the caption with the image, "2 weeks ago I posted this pic on my wall asking if anyone had seen nails like this. A few google posts later and I was urged to go to the Doctor. A tad extreme I thought...."

She continued to say, "I was rushed for blood tests and a chest xray, 2 days later I got a phone call to go for a CT scan, 2 days later a PET scan and more blood test, the day later a breathing test on my lungs and a scan on my heart, the day later an MRI scan then a lung biopsy. After a gruelling 2 weeks, yesterday I got my results.......Cancer in both my lungs !!!!"

She went on to say that she had no idea that her curved nail could be related to cancer. She said, "When your nails curve it's often linked to heart and lung disease and its official term is "clubbing" I had no idea....Did You ????"

She ended the post by stating that she hopes sharing this image can help other people get checked out. She said, "Hope this post can help someone else in the early stages of cancer. Big shout out to the NHS you have been excellent and I thank all the staff that have dealt with my diagnosis."
