Dr. 琼斯: The number one cause of cancer deaths in women? 大多数女性会说是乳腺癌, 但这是肺癌, and although the rate of lung cancer in men is falling, 女性肺癌死亡人数正在上升. 这是博士. Kirtly Jones from the Department of Obstetrics and Gynecology at University of Utah Health Care and November is Lung Cancer Awareness Month. 女性肺癌，今天的《大发体育官网》节目.
播音员: Medical news and research from University Utah physicians and specialists you can use for a happier and healthier life. 您正在收听的是范围.
Dr. 琼斯: 白丝带. We see pink ribbons everywhere for breast cancer, 为卵巢癌准备的青色丝带, but where are the white ribbons for lung cancer? The CDC reports that more women die of lung cancer than breast, 子宫, 和卵巢癌的总和. Twenty-seven percent of all cancer deaths in the US are caused by lung cancer. The five year survival rate for those diagnosed with lung cancer is 16%, 这使得它成为一种特别致命的癌症. 现在, the lung cancer rate has fallen 21% among men, 但原因尚不清楚, 女性的自杀率上升了116%. Of course, we all know that smoking is the major risk factor. Since 1960, the rate of smoking in men has gone down, but for women, not so much.
Lung cancer develops differently in women than men. Women who have never smoked have a greater risk of developing lung cancer than men who've never smoked. 去图. Worldwide, 53% of women with lung cancer were never smokers. They could have been exposed to more indoor air pollution related to cooking and heating, and that may be the risk factor for women in Asia and in China and somewhat in the United States. Women tend to develop lung cancer at a younger age than men, too. The good news is women are more likely than men to be diagnosed in early stages of lung cancer, 因为女性可能会得到更多的医疗保健, and women tend to live longer than men after treatment for lung cancer. 所以，这是好消息.
好吧, I'm thrilled to live in Utah where smoking is so uncommon, and where it's against the law to smoke in enclosed public places. 然而, a notable trend in the increase in lung cancer among healthy non-smokers is known primarily in women. If lung cancers in non-smokers were its own category, it would rank among the top 10 of fatal cancers in the US. Lung cancer can result from factors other than smoking. 基因突变, 以及暴露在氡气中, 二手烟, 空气污染及石棉, 除此之外. In Utah, we have particular geographic risks related to radon and air pollution.
So, what to do for this largely preventable, common cancer? 如果你吸烟，你应该戒烟. 戒烟十年后, your risk of lung cancer is half of what it would have been if you didn't quit. 如果你是50岁以上的老烟民, talk to your doctor about the pros and cons of low dose CT scans for screening. 如果你不吸烟，不要开始. If you're an adolescent or the parents of one, 开始吸烟尤其糟糕, as you're more likely to be addicted to nicotine, and have your developing brain wired for risky behavior, 像酒精.
降低吸二手烟的风险. If someone in your family smokes, no smoking in the house or in the car. 检查家里是否有氡. 现在, radon is a naturally occurring radioactive gas that results from the breakdown of uranium and soil and rocks. 它看不见, 尝过, 或闻起来, 根据环保署的说法, radon is the second leading cause of lung cancer in this country, and it's the leading cause among non-smokers. 在户外, there's so little radon that it's not likely to be dangerous, 但在室内, 氡可以更浓缩. When it's breathed in, it enters the lungs and exposes them to radiation. 美国部分地区的房屋, 像犹他州, which are built on soil with natural uranium deposits can have high indoor radon levels, 尤其是在地下室. My basement is ventilated and has a fan in it specifically for that reason, 我住在盐湖城.
If you are concerned about radon exposure, you can use a radon detection kit. State and local offices of the EPA can give you the names of reliable companies who can test your home. 所以去检查一下，把它修好. Limit your time on the freeway and be an advocate for clean air. 多吃水果和蔬菜. Antioxidants in your diet is associated with lower risk of lung cancer. 维生素片不起作用. So, ladies and gentlemen, put on your white ribbons this month. Lung cancer is largely a preventable disease. Think about the air you breathe and what's in it. 保护好自己和身边的人. 这是博士. Kirtly Jones and thank you for joining us on 范围.
