Lung cancer is the leading cause of cancer death among both men and women; about 1 out of 4 cancer deaths are from lung cancer. Each year more people die of lung cancer than of colon, breast, and prostate cancers combined. Non-small Cell Lung Cancer (NSCLC) is the most common type of lung cancer, accounting for 80% to 85% of all lung cancer diagnoses, which is what Bevacizumb treats.
