Smoking is associated with about a dozen localizations of cancer, and lung cancer is only one of them. In second place in frequency are tumors of the head and neck: mouth, larynx and throat. These are the upper respiratory tracts that first come into contact with tobacco smoke. Esophageal cancer follows. This information with the journalist sb.by shared Deputy Director for scientific work RSPC pulmonology and phtisiatrics Dmitry Ruzanov.
- The cigarette contains about two dozen known carcinogens that can cause tumors of different localizations. In third place - cancer of the stomach, pancreas, bladder and kidneys. Carcinogens of tobacco smoke are retained not only in the lungs: they are well absorbed into the bloodstream, spread throughout the body, filtered in the kidneys and remain in the bladder for a long time. About 30 percent of all cancer deaths in the world are related to tobacco, so in cancer prevention, quitting smoking is not one of the points, but the number one.
There are no universal symptoms that would allow to suspect cancer at an early stage. The tumor itself does not hurt, and the lungs that do not have pain receptors, especially not sore. But there are signs at which it is necessary, without delay, to seek medical care. One of the important symptoms characteristic of most forms of lung cancer is a cough. If it lasts more than two or three weeks and does not tend to fade, this is a reason to go to the doctor. The next terrible symptom, more often related to the late ones, is hemoptysis: even one streak of blood in sputum should be alerted. With lung cancer, shortness of breath is also important, which increases without any reason. Common signs include weight loss, increasing weakness, night sweats, as well as recurring pneumonia in the same place, pneumonia, which do not resolve for a long time or leave changes in the lungs. In Belarus, the detection of cancer in the early stages exceeds 90%
