Know more lung cancer 了解更多肺癌
重要事实：肺癌是全世界癌症相关死亡的主要原因，男性和女性的死亡率均为最高。
吸烟是肺癌的主要原因，约占所有病例的85%。
肺癌常常在治疗选择有限的晚期才被诊断出来。
筛查高危个体有可能及早发现病例并显著提高存活率。
一级预防（如烟草控制措施和减少接触环境风险因素）可以降低肺癌的发病率并挽救生命。
肺癌是当异常细胞在肺部以不受控制的方式生长时开始的一种癌症。它是一个严重的健康问题，可以导致严重的伤害和死亡。
肺癌的症状包括不消停的咳嗽、胸痛和呼吸急促。
尽早就医以避免严重的健康影响非常重要。治疗取决于患者的病史和疾病的阶段。
最常见的肺癌类型是非小细胞癌（NSCLC）和小细胞癌（SCLC）。非小细胞癌更常见且生长缓慢，而小细胞癌不太常见，但常常生长迅速。
肺癌是一个重大的公共卫生问题，在全球造成大量死亡。国际癌症研究机构（IARC）对癌症发病率和死亡率的GLOBOCAN（全球癌症观察站）2020年估计显示，肺癌仍然是癌症死亡的主要原因，2020年估计造成180万人死亡（18%）。
吸烟（包括香烟、雪茄和烟斗）是肺癌的主要高危因素，但也可以影响非吸烟者。其他高危因素包括接触二手烟、职业危害（如石棉、氡和某些化学品）、空气污染、遗传性癌症综合征和以前的慢性肺部疾病。
肺癌可以引起若干症状，可能表明肺部有问题。
最常见的症状包括：不消停的咳嗽; 胸痛; 呼吸短促; 咳血（咯血）; 疲劳; 不明原因的体重减轻; 肺部感染不断复发。
早期症状可能较轻或被视为常见的呼吸系统问题，导致诊断延迟。
预防 : 不吸烟是预防肺癌的最佳方法。
应避免的其它高危因素包括：二手烟雾; 空气污染; 工作场所的危害，如化学品和石棉。早期治疗可以防止肺癌恶化并扩散到身体的其他部位。

Key Facts: Lung cancer is the leading cause of cancer-related death worldwide, with the highest mortality rates among both men and women.
Smoking is the leading cause of lung cancer, accounting for approximately 85% of all cases.
Lung cancer is often diagnosed at an advanced stage when treatment options are limited.
Screening high-risk individuals has the potential to detect cases early and significantly improve survival rates.
Primary prevention, such as tobacco control measures and reducing exposure to environmental risk factors, can reduce lung cancer incidence and save lives.
Lung cancer is a type of cancer that begins when abnormal cells grow in an uncontrolled manner in the lungs. It is a serious health problem that can lead to serious injury and death.
Symptoms of lung cancer include a non-stop cough, chest pain and shortness of breath.
It is important to seek medical attention early to avoid serious health effects. Treatment depends on the patient's medical history and the stage of the disease.
The most common types of lung cancer are non-small cell carcinoma (NSCLC) and small cell carcinoma (SCLC). Non-small cell cancer is more common and slow-growing, while small cell cancer is less common but often grows quickly.
Lung cancer is a major public health problem causing a large number of deaths worldwide. The International Agency for Research on Cancer (IARC) GLOBOCAN (Global Observatory on Cancer) 2020 estimates of cancer incidence and mortality show that lung cancer remains the leading cause of cancer death, accounting for an estimated 1.8 million deaths (18%) in 2020.
Smoking (including cigarettes, cigars, and pipes) is the main risk factor for lung cancer, but it can also affect non-smokers. Other high-risk factors include exposure to second-hand smoke, occupational hazards (such as asbestos, radon, and certain chemicals), air pollution, hereditary cancer syndromes, and previous chronic lung disease.
Lung cancer can cause several symptoms that may indicate a problem with the lungs.
The most common symptoms include: a cough that won't stop; chest pain; shortness of breath; coughing up blood (hemoptysis); fatigue; unexplained weight loss; and recurring lung infections.
Early symptoms may be mild or considered a common respiratory problem, leading to a delay in diagnosis.
Prevention: Not smoking is the best way to prevent lung cancer.
Other high-risk factors to avoid include: second-hand smoke; air pollution; workplace hazards such as chemicals and asbestos. Early treatment can prevent lung cancer from getting worse and spreading to other parts of the body.
