Lung carcinoid tumors
This type of tumor is considered separately from other lung cancers. It is rare--there are only about 1,700 cases of this cancer a year, according to the American Cancer Society. These growths arise from specific cells responsible for secreting hormones like adrenaline. Most often, carcinoid tumors are found in the gastrointestinal tract, but they can also be found in the lungs. Typical carcinoids grow very slowly, while atypical carcinoids grow marginally more quickly.
Both have relatively good prognoses, especially compared with other types of lung cancer. The ACS says that the five-year survival rate for people with typical lung carcinoids is about 95 percent and that the rate is about 70 percent for people with atypical lung carcinoids. Most are cured with surgery, and chemotherapy and radiation are used primarily in the rare cases where the cancer has spread or cannot be removed surgically.
