Cancer causes millions of deaths worldwide every year despite the fact that many cancers can be cured and treated effectively if detected early. In 2020, cancer caused nearly 10 million deaths worldwide, according to WHO estimates. The five most common cancers reported worldwide are breast, lung, colorectal, stomach and prostate cancers. While breast cancer topped in terms of new cases of cancer with 2.26 million cases in 2020, lung cancer caused the highest number of cancer deaths in the same year (1.80 million deaths).


Lung Cancer

Smokers have the greatest risk of developing lung cancer, but it can also occur in people who have never smoked. Apart from smoking and exposure to secondhand smoke, risk factors for lung cancer include family history of lung cancer, radiation therapy, exposure to radon gas, asbestos and other carcinogens.
