Lung Cancer: Still Number 1
Rate This
Lung cancer still kills more women than breast cancer does. Lung cancer is the leading cancer killer for women, men, Americans, and people worldwide. According to a review from the Mayo Clinic, we are making progress: the incidence is on the decline in the United States. But it's still Number One.
My newspaper this morning had a special pink section on breast cancer. This Number Two cancer killer of women gets ribbons, fund-raisers, annual screenings, and constant attention. Maybe it's time to give a little more attention to Number One.
Approximately 85 to 90 percent of lung cancers are attributed to smoking tobacco products. After a person stops smoking, the risk gradually decreases. Former smokers reach a level of lung health comparable to those who have never smoked if they survive smoke-free for 10 years. But too many of them die before the end of that decade. In a study of 5,000 patients with lung cancer diagnosed between 1997 and 2002, only 25 percent were current smokers and over 60 percent were former smokers.
The American Cancer Society does not yet recommend screening for lung cancer, even for individuals at risk. At first this sounds amazing to me. The Mayo Clinic article reports that the only reasonable hope for curing lung cancer is surgery at a very early stage, before the tumor develops metastases or locally advanced disease. Approximately 70 percent of cases are diagnosed too late for surgery. The overall 5-year survival rate is only 15 percent. So shouldn't we be looking for early lung cancers in smokers and former smokers?
The problem is that 25 to 60 percent of screening CT scans of smokers and former smokers show lung abnormalities. Most of these are not cancer, but it's not yet possible to identify which ones are malignant without invasive biopsy tests. The National Lung Screen Trial is currently underway to collect data on whether spiral CT scans or chest x-rays provide better data.
No one is absolutely safe from lung cancer. About 10 to 15 percent of lung cancers occur in people who have never smoked. Risk factors include air pollution, second hand smoke, and occupational exposure to inhaled carcinogens including asbestos, silica dust, and radioactive particles.
I watched one of my friends die of lung cancer. It was horrible, even with the best available care. I hope we can raise awareness and funding for this Number One cancer killer.

I love the tone of this article. Lung cancer is one of the most deadly forms of cancer, yet also one of the least funded and most stigmatized. It's great what we do to raise awareness about breast cancer nationally, but it'd be even better to keep the momentum going by striving to find a cure during Lung Cancer Awareness Month too. Until we have a cure, education is key and posts like this are a great step.
