🆕 New Concept Discovered: Cancer Risk Factors
Understanding how lifestyle and environmental factors contribute to cancer mortality.

Step 1: Analyze the options and statistical data

Public health organizations, such as the World Health Organization (WHO) and the American Cancer Society (ACS), track the leading causes of cancer deaths globally and regionally:

• Heredity/family history: Inherited genetic mutations account for only about \(5\%\) to \(10\%\) of all cancers.
• Tobacco use: Tobacco use is the leading cause of cancer and cancer death worldwide. It is consistently linked to approximately \(30\%\) of all cancer deaths (and about \(85\%\) of all lung cancer deaths) in developed nations.
• Pollution: Environmental pollution (such as outdoor air pollution) is linked to a much smaller percentage of cancer deaths, typically around \(1\%\) to \(4\%\).
• Ultraviolet radiation: While UV radiation from sunlight or tanning beds is the primary cause of skin cancers, it accounts for a small percentage of total overall cancer deaths.

Step 2: Match with the correct option

The statistic of "about \(30\%\) of cancer deaths" directly aligns with the impact of tobacco use.

Answer:

b) tobacco use
