There are usually no symptoms or warning signs in the early stages of lung cancer. As it progresses, what you may notice:
describes how far someone’s cancer has spread. Small-cell lung cancer is divided into two stages:"Limited" means the cancer is confined to one lung and maybe nearby lymph nodes."Extensive" means the cancer has spread to the other lung or beyond. Non-small-cell lung cancer is assigned a stage of I through IV, depending on how far it has spread.When doctors find non-small-cell lung cancer before it spreads beyond one lung, an operation can sometimes help.
and chemotherapy can shrink tumors and help control symptoms, such as bone pain or blocked airways. Chemotherapy is usually the main treatment for small-cell lung cancer.plus chemotherapy may help, if other approaches don’t work. One type prevents the growth of new blood vessels that feed cancer cells. Others interrupt the signals that prompt lung cancer cells to multiply, as shown in the image here.
at home or at work also appears to raise your risk. People who are married to someone who smokes are 20% to 30% more likely to get lung cancer than the spouses of nonsmokers.Some jobs make lung cancer more likely. People who work with uranium, arsenic, and other chemicals should try to limit their exposure.
