Did you know that lung cancer is the second most common cancer in both men and women? Did you also know that according to the American Cancer Society, lung cancer is the leading cause of cancer death among men and women. Each year, more people die of lung cancer than of colon, breast and prostate cancers combined. This is true because lung cancer is typically already more advanced when someone seeks medical attention for already existing symptoms. This makes early diagnosis crucial, as it provides the best chance for effective treatment options and better prognosis.
