Detailed introduction: Is lung cancer contagious?

Lung cancer is not contagious. There are several types of primary bronchial lung cancer (lung cancer), but only one is common, which is bronchial carcinoma. Lung damage caused by smoking is almost certainly the cause of cancer. Inhaling smoke will damage the bronchial mucosal cells. Many scientists believe that the damaged cells themselves represent an early form of cancer.

You often have chest pain. This pain may be sharp when you take a deep breath, or it may be dull and constant. Sometimes you may also have wheezing. Sometimes the first symptoms of lung cancer occur in organs that have spread to the lung cancer. About 1 in 8 cases of bronchial cancer will spread, and it is this secondary cancer that alerts doctors to the presence of primary lung cancer. The symptoms of secondary lung cancer depend on where the cancer cells have spread. If they are in your brain, you may have headaches, mental confusion, or seizures and strokes. If the cancer spreads to the bones, the symptoms are pain, swelling, or broken bones. If the cancer gets into the skin, the symptoms are cystic swelling. If the cancer spreads to the liver, the symptoms may be indigestion, indigestion, and eventually jaundice.
