Concerned commenters urged Taylor to see a doctor, which she did.

What followed was two weeks of testing, before a diagnosis that changed her life.

Taylor was diagnosed with cancer in both lungs.

She warned others of her story and symptom with a message posted to the Facebook page of local newspaper Wigan Today.

"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," Taylor wrote.

"After a gruelling 2 weeks, yesterday I got my results.......Cancer in both my lungs !!!!."

The condition, known as nail clubbing or digit clubbing, is a para-neoplastic syndrome -- a rare disorder triggered by an altered immune system response.

While there exact cause of nail clubbing in some people is not known, it can be the result of the immune system's response to platelets clumping, states the World Journal of Clinical Oncology's article Paraneoplastic syndromes associated with lung cancer.

Another theory to the cause of nail clubbing is a lack of oxygen circulating the body, the U.S. National Library of Medicine explains.
