Verified step by step guidance

Identify the key risk factors for lung cancer. Smoking is widely recognized as the leading risk factor for developing lung cancer, accounting for the majority of cases.

Understand the role of age in lung cancer prevalence. Lung cancer is more common in older adults, particularly those over the age of 65, rather than individuals under the age of 30.

Recognize the importance of imaging techniques in detecting lung cancer. CT scans and other imaging methods are crucial tools for diagnosing lung cancer, allowing for early detection and treatment.

Consider the influence of genetic and environmental factors on lung cancer. While genetic factors can play a role, environmental factors, especially smoking, have a significant impact on lung cancer risk.

Evaluate the statements provided and determine which one accurately reflects the current understanding of lung cancer risk factors. The statement that smoking is the leading risk factor for developing lung cancer is true.
