Question

1) Smoking
2) Poor diet
3) Lack of exercise
4) Excessive alcohol consumption

Answer 1

1) Smoking is the primary cause of preventable cancer deaths in the United States, contributing to around 90% of lung cancer fatalities, and is the leading cause of various other deadly cancers.

Step-by-step explanation:

The primary cause of preventable cancer deaths in the United States is smoking. Smoking contributes to a significant percentage of lung cancer fatalities, with about 90% being associated with tobacco smoke. Moreover, smoking is the leading cause of many other deadly cancers.

In contrast, other lifestyle choices such as poor diet, lack of exercise, and excessive alcohol consumption also play significant roles in cancer development, with poor diet and physical inactivity contributing to at least one-third of cancer deaths. However, the impact of smoking on cancer mortality is particularly stark, as regular smokers die about 10 years earlier than non-smokers and not using tobacco could prevent an estimated 25 percent of cancer deaths.
