肺癌是一个致死率极高的恶性疾病，是全球头号的癌症杀手，而早诊断、早治疗是提高肺癌总体治疗效果的唯一途径。专家指出，通过规范化治疗和多学科联合诊治，晚期肺癌的总生存时间从过去的2-4个月延长到现在30个月左右。
01
发病：肺癌致死率极高，号称“全球头号癌症杀手”
肺癌并非是不治之症，科学防治肺癌，从了解肺癌开始。据悉，不论是发达西方国家还是中国，肺癌的发病率和死亡率高居恶性肿瘤前列，我国每年有60万人死于肺癌，已成为名副其实的“肺癌第一大国”
[1]。因为肺癌是一个致死率极高的恶性疾病，是“全球头号的癌症杀手”。
从1985年以来，肺癌已成为全世界发病率和死亡率最高的恶性肿瘤，每年因肺癌死亡的人数多于乳腺癌、前列腺癌和肠癌死亡人数的总和。目前，肺癌已成为一个严重的公共健康问题。预计到2025年，我国每年仅死于肺癌的人数将接近100万人。
据我国的数据显示，肺癌在男性癌症死因中已居首位，在女性中仅次于乳腺癌居第二位。在城镇癌症死亡病例中，每3至4人中即有1人是肺癌。多在40岁以上发病，发病年龄高峰在50~65岁之间。
02
肺癌的病因
肺癌发病病因主要有吸烟、环境污染、职业接触、肺部慢性病以及遗传基因易感性等。其中吸烟是肺癌发病的首位高危因素，80%以上的肺癌被认为是由于吸烟而引起
[2]。据悉，吸烟者患肺癌的几率比不吸烟者高10倍以上，尤其是50岁以上、20年吸烟史及平均每天吸20支烟，这类患者的肺癌风险就是非常高了。
有报道称，近年来在临床女性患上肺癌的比例明显上升。有研究表明可能和中国女性烹饪习惯中产生的厨房高油烟有关。很多女性长期接触厨房油烟、喜欢用高温煎炸食物、做饭时厨房门窗关闭，导致厨房小环境油烟污染严重，毒烟雾长期刺激眼和咽喉，会损伤呼吸系统细胞组织。
另外，像大气污染、居住环境的空气污染、工作压力大等也是诱发肺癌的重要因素。此外，肺结核、支气管扩张慢性肺病，也是高危人群，尤其需要关注和定期筛查。还有一部分是职业病患者，比如煤矿工人、接触如石棉等化学制剂的工人，他们都是尘肺病和肺癌的高危人群。
03
体检很重要
目前在中国80%的肺癌病人一发现已是晚期
[3]，失去了手术机会。早期肺癌无任何症状，只能靠体检发现。
肺癌的可疑症状包括：干咳，咯血，胸背痛。干咳是肺癌最早期的症状，尤其是在没有感冒和咽炎等情况下干咳超过两周，必要时要做CT检查，如果出现咯血和胸背痛等情况，就更加提示肺癌的可能。
在日本为40岁以上吸烟者行免费肺癌体检，他们对控烟非常严格，室内严禁吸烟，就算在室外吸烟，烟灰也不能弹在地上，违反者都需要罚款。他们有60%的早期肺癌发现率，但中国只有2%-5%，差距非常大，所以我们还需要不断努力。
低剂量胸部CT是发现早期肺癌的最有效的方法，其敏感度是常规胸片的4-10倍，可以检出早期周围型肺癌。国际早期肺癌行动计划数据显示，低剂量胸部CT年度筛查能发现85%的I期周围型肺癌，术后10年预期生存率达92%，可以降低整体肺癌死亡率20%左右。所以有肺癌高危因素的人群建议每年检查胸部CT。2015年四川大学华西医院为本单位四十岁以上职工胸部CT体检，在1389名员工中共发现确诊了21例肺癌。非常令人震惊，其中男女的发病率是相近的。
04
胸片、胸透能起到早期筛查肺癌的作用吗？
做胸透和拍胸片，如果有肿块挡在心脏、食管、膈肌、肋骨后面，特别是对于小于1cm的小结节，医生是看不见的。有些人也许会有疑问，为什么肺癌那么可怕，病人自己却没有明显不适？这跟我们肺的结构有一定关系，人体有五个肺叶，左肺有两个肺叶，右肺有三个肺叶，人体只要有两个肺叶能正常工作就能基本正常地生活，最多出现易疲劳、气短等表现，所以很多时候当出现症状后已经是肺癌晚期了，这也是肺癌最恐怖的地方
CT进入中国30多年，低剂量螺旋CT对肺癌患者的早期诊断、肺癌生存质量改善、降低病死率有很大作用
[4]。目前在很多地方，政府已经认识到CT对发现早期肿瘤的作用，CT的价格也在逐渐下降。
目前一个晚期肺癌患者在中国大陆，平均治疗花费11万元，而且治疗后生存期是按月计算，并不长。如果可以早期发现，术后一般不需要化疗，只需要注意复查，一个微创手术大概5-6万，术后可以达到长期生存目的，10年生存率达到90%。而真正到了晚期，11万仅仅只是平均数字，有些甚至达到了几十万元，几百万。
一些人认为国内技术有限，跑到外国去治疗，其实国内外的治疗区别不大，主要是病情发展到了一定阶段，并不是说去了最好的医院就能治好的，因为全世界的医学信息是共享的，国内外最大的区别可能在于一些美国上市的药物中国还没有上市，但是那些药都是非常贵的。
05
高危人群多久做一次CT比较合适？
“如果有上述的高危因素，年纪超过50岁，有长期吸烟史、家族里有肺癌病史或者既往检查发现有肺部结节的，建议每年做一次胸部CT。但如果抽烟大于20年的，即使没到50岁，也建议每年做一次胸部CT。”
专家认为，“如果筛查时发现肺里有小结节，就要根据肺部结节的大小和性质来决定随访的间隔，以明确疾病性质以及是否要做手术。肺癌筛查用的不是CT的常规剂量，是低剂量的螺旋CT，这时的射线是正常射线量的1/6，也就是连续6年，每年做一次CT筛查，辐射剂量跟平时一次CT的剂量一样。即使是按照常规剂量计算，几年做一次胸部CT对于健康也没有什么影响。”
06
肺部小结节是肺癌吗？
肺癌早期有相当一部分表现为结节，但是结节也可能是良性病变，恶性结节占30%-40%。临床中一般认为肺部结节小于0.8厘米，边缘清楚光滑的，良性的可能性比较大，但仍然需要定期观察，如果结节在短时间内快速增大，则不能排除是恶性的（如果是恶性结节，病变增大一倍的时间约为300～400天；如果结节倍增时间大于600天，那么说明其恶性概率很低。）
大多数结节在两年内未观察到生长，一般可视为良性。如果肺部结节大小超过0.8厘米，特别是边缘不规则，看上去有又短又细的毛，则认为恶性的可能性比较高。
