Lung cancer is the leading cause of cancer deaths in the world, and it is responsible for more deaths than breast, colon, and prostate cancers combined. In the United States, lung cancer kills more people than car accidents, gun violence, and HIV/AIDS combined.
Lung cancer is a type of cancer that starts in the lungs. It can occur in either the left or right lung, and it can spread to other parts of the body, such as the lymph nodes, bones, and brain.
There are two main types of lung cancer: small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). SCLC is a more aggressive type of lung cancer that is more likely to spread to other parts of the body. NSCLC is a less aggressive type of lung cancer that is more likely to be found at an early stage.
Lung cancer is caused by a number of factors, including smoking, exposure to secondhand smoke, and exposure to radon gas. Smoking is the leading cause of lung cancer, and it is responsible for about 90% of cases. Secondhand smoke is the smoke that is exhaled by smokers, and it can be just as harmful as smoking firsthand. Radon gas is a radioactive gas that can be found in the air and in the soil. Exposure to radon gas can increase the risk of lung cancer.
The symptoms of lung cancer can vary depending on the stage of the cancer. In the early stages, there may be no symptoms at all. As the cancer grows, symptoms may include:
If you experience any of these symptoms, it is important to see your doctor right away. Early diagnosis and treatment of lung cancer can improve your chances of survival.
Lung cancer is a serious disease, but it is important to remember that there is hope. With early diagnosis and treatment, many people with lung cancer can live long and full lives.
