Throughout the ages, people have attached great importance to the eyes. They are often even said to be a window to the soul. And although this is more of an expression in literature and art, modern researchers believe that it is possible to learn about many diseases just by looking into a person's eyes
For example, recently scientists from the USA discovered that some types of cancer can be identified by the eyes. Moreover, they even pointed out the symptoms that accompany this cancer. It turned out that for some of them they had not even made an impression on the doctors before.
Experts have identified external signs that scream about the presence of cancer. For example, small pupils can indicate the presence of cancer cells in the lungs. Lower eyelids or their weak tone should also be considered warning symptoms. In addition to this, cancer patients experience pain in the shoulder area and the face stops sweating even in hot weather.
"When we discovered the connection between these symptoms and lung cancer, we were shocked. After all, no such connection has been established before. None of the oncologists would have thought of it," says Dr. Clay Johnson. who is one of the authors of the scientific work.
Scientists believe these data are particularly valuable to general practitioners. Lung cancer detection is quite a complicated process compared to other types of cancer. This is because the signs are often identical to those of the common cold.
