Employees of the National Health Service of England (NHS), found that the development of lung cancer in the human body can be determined not only by the main symptoms – cough, chest pain, phlegm, wheezing, but also by the condition of the fingers and nails. And if the first of the listed signs in oncology appear, as a rule, already in the late stages of the disease, then the latter allows it to be diagnosed much earlier.

It is about enlarging or thickening the tips of the fingers. This is due to the production of certain hormone-like chemicals, under the influence of which more fluid and blood begins to flow to the limbs. Thus, the tissues at the fingertips are changed. When viewed from the side, the nails look atypically convex, and the skin near them acquires shine.
Doctors focused on the fact that these symptoms are not a mandatory sign of lung cancer, but they should still be the basis for a visit to the doctor. Sometimes enlargement of the fingers and shine of the skin around the nails indicate chronic lung infections or a heart defect.
