5. Trachea, bronchus, and lung cancers
Respiratory cancers include cancers of the trachea, larynx, bronchus, and lungs. The main causes are smoking, secondhand smoke, and environmental toxins. But household pollutions such as fuels and mold also contribute.
Impact of respiratory cancers around the world
A 2015 study reports that respiratory cancer accounts for about 4 million deaths annually. In developing countries, researchers project an 81- to 100-percent increase in respiratory cancers due to pollution and smoking. Many Asian countries, especially India, still use coal for cooking. Solid fuel emissions account for 17 percent of lung cancer deaths in men and 22 percent in women.
Risk factors and prevention
Trachea, bronchus, and lung cancers can affect anyone, but they’re most likely to affect those who have a history of smoking or tobacco use. Other risk factors for these cancers include family history and exposure to environmental factors, such as diesel fumes.
Aside from avoiding fumes and tobacco products, it isn’t known if there’s anything else that can be done to prevent lung cancers. However, early detection can improve your outlook and reduce the symptoms of respiratory cancer.
