From Cancer Treatment Centers of America:

In recognition of Lung Cancer Awareness Month this November, Cancer Treatment Centers of America (CTCA), is partnering with the American Lung Association to educate people that the #1 Cancer killer is Not What You Think.

WHY: Lung cancer is misunderstood

Myth: Lung cancer rates are trending down for everyone.

Fact: While rates of lung cancer among men have fallen in the last 41 years, the rate of women dying from lung cancer has increased 87%. According to the American Lung Association, however, only 3% of women consider lung cancer a top-of-mind cancer concern.

"In the United States, lung cancer is now the leading cancer killer of women, having surpassed breast cancer in 1987. Almost twice as many women in the United States are expected to die from lung cancer compared with breast cancer in 2018 (approximately 70,000 versus 41,000)". Several large randomized studies concluded that women who take estrogen plus progesterone as part of menopausal hormone replacement therapy (HRT) have an increased risk of lung cancer.

"The prospective Vitamins and Lifestyle (VITAL) Study followed a cohort of over 36,000 peri- and postmenopausal women during six years of follow-up. After adjusting for smoking and other confounding factors, the risk of incident lung cancer was increased for those who used an estrogen plus progestin. The risk was proportional to duration of hormone exposure (HR 1.48, 95% CI 1.03-2.12 for those with â‰¥10 years exposure to an estrogen plus progestin)."

Myth: Everyone who gets lung cancer is a smoker.

Fact: Radon - a colorless, odorless gas which is quite common in households that aren't well ventilated - is the second-leading cause (after smoking) of lung cancer in the U.S. It's estimated that 1 in 13 homes have unsafe levels of radon gas. According to the American Lung Association, exposure to secondhand smoke, radon, and air pollution are also known causes of lung cancer, and sometimes there is no known cause of lung cancer.

At this time, smoking is considered the only reason for routine screening, though there are other risk factors associated with increased risk of lung cancer also:

Radon exposure
Radiation exposure
Work-related chemical exposure
Family history
And, possibly diet though much research is still needed in this area

Myth: There is no screening for lung cancer

Fact: There is a newly available lung cancer screening for those considered at high risk for the disease. Screening leads to early detection of the disease, when there are more treatment options and the disease is most curable.

The low-dose CT is considered for people at higher risk of developing lung cancer. At this time, the criteria for this screening test is:

The U.S. Preventive Services Task Force recommends yearly lung cancer screening with LDCT for people who-

Have a history of heavy smoking, and
Smoke now or have quit within the past 15 years, and
Are between 55 and 80 years old

Myth: Breast cancer kills more people than any other kind of cancer.

Fact: The average 5-year survival for lung cancer is among the lowest of all types of cancer. In fact, lung cancer is the leading cancer killer, killing more people than colon, breast and prostate cancers combined.

Many agencies including the American Cancer Association, American Lung Association, the CDC and other governmental and private entities are working to eradicate lung cancer. However, more research is needed.
