Verified step by step guidance

Identify the key concepts related to tobacco use and cancer risk. These include the impact of tobacco on various organs, the benefits of quitting tobacco, and the association between tobacco use and lung cancer.

Understand that tobacco contains carcinogens, which are substances that can lead to cancer. These carcinogens can affect multiple organs, not just the lungs, increasing the risk of various cancers.

Recognize that quitting tobacco use can lead to a reduction in cancer risk over time. This is because the body begins to repair itself and the exposure to carcinogens decreases.

Acknowledge that tobacco use is a well-established leading cause of lung cancer due to the direct exposure of lung tissue to harmful substances in tobacco smoke.

Evaluate the statement 'Tobacco use has no impact on the risk of developing cancer.' Given the scientific evidence, this statement is false because tobacco use is a significant risk factor for developing cancer.
