Explanation:

🆕 New Concept Discovered: Risk Factors for Head and Neck Cancers
Identifying primary behavioral and environmental causes of specific cancers.

Step 1: Identify the primary risk factors

Head and neck cancers include cancers of the mouth, throat, larynx, sinuses, and salivary glands. Historically and statistically, the vast majority of these cancers (at least 75%) are caused by the combined or individual use of tobacco and alcohol.

Step 2: Evaluate the options

• a) consumption of processed foods: While linked to some gastrointestinal cancers, it is not the primary cause of head and neck cancers.
• b) alcohol and tobacco use: This is the leading risk factor worldwide, especially when used together, as they have a synergistic effect.
• c) HPV infection: Human papillomavirus (HPV) is a significant and rising cause of specific throat cancers (oropharyngeal cancer), but tobacco and alcohol use still account for the majority of overall head and neck cancers globally.
• d) drug use: Illicit drug use is not a primary established risk factor for these cancers.

Answer:

b) alcohol and tobacco use.
