Lung Cancer
Lung cancer is currently the second most prevalent cancer in men and women, after skin cancer. Sadly, lung cancer is also one of the most serious cancers, but the number of new lung cancer cases is continuing to decrease, in part because more and more people have stopped smoking. Plus, with advances in early detection and new treatments, lung cancer survival rates are rising each year.
What is lung cancer?
Cancer starts when cells in the body begin to grow out of control. Lung cancers begin in the lungs and typically in the cells lining the bronchi and part of the lung such as bronchioles or alveoli.
There are two main types of lung cancer:
- Non-small cell lung cancer (NSCLC) which accounts for approximately 80-85%% of all lung cancers. Types of NSCLC include: adenocarcinoma, squamous cell carcinoma and large cell carcinoma.
- Small cell lung cancer (SCLC) accounts for 10-15% of lung cancers and tends to grow and spread faster than NSCLC.
Statistically, lung cancer accounts for over 238,000 new cancer cases each year according to the American Cancer Society estimates.
For 2023, The American Cancer Society estimates:
Lung cancer (both small cell and non-small cell) is the second most common cancer in both men and women in the United States (not counting skin cancer). In men, prostate cancer is more common, while in women breast cancer is more common.
