Final answer:
Lung cancer is the leading fatal cancer in both males and females. It is not the most common type of cancer, but it causes the highest number of cancer-related deaths. Tobacco smoke exposure is the main cause of lung cancer.
Step-by-step explanation:
The leading fatal cancer in both males and females is lung cancer. According to statistics, lung cancer causes more cancer deaths than any other type of cancer in adults.
While lung cancer may not be the most common type of cancer, it is responsible for the highest number of cancer-related deaths. This can be attributed to the fact that lung cancer is most often caused by exposure to tobacco smoke, which is a significant risk factor.
It is important to promote awareness about the dangers of tobacco smoke and encourage smoking cessation to reduce the incidence and mortality rates associated with lung cancer.
