1. What is the HANC RC?

The Head And Neck Risk Calculator (HANC RC) estimates the risk of developing head and neck cancer based on age, smoking history, alcohol consumption, and HPV status. It provides a personalized risk assessment to aid in prevention and early detection strategies.

2. How Does the Calculator Work?

The calculator uses a specialized algorithm that incorporates:

Where:

• Age — Years
• Smoking — Pack-years (packs per day × years smoked)
• Alcohol — Units consumed per week
• HPV — Human papillomavirus infection status

Explanation: The equation weights these risk factors according to their established associations with head and neck cancer development.

3. Importance of Head and Neck Cancer Risk Assessment

Details: Early risk identification allows for targeted screening, lifestyle modifications, and preventive measures that can significantly reduce cancer incidence and improve outcomes.

4. Using the Calculator

Tips: Enter accurate information about age, smoking history, alcohol consumption, and known HPV status. All values must be valid (age between 18-120, non-negative values for smoking and alcohol).

5. Frequently Asked Questions (FAQ)

Q1: What constitutes a pack-year?
A: One pack-year equals smoking one pack (20 cigarettes) per day for one year. 2 packs per day for 10 years = 20 pack-years.

Q2: How is alcohol consumption measured?
A: One alcohol unit typically equals 10ml or 8g of pure alcohol - approximately one small glass of wine, half pint of beer, or single measure of spirits.

Q3: Why is HPV status important?
A: HPV infection, particularly HPV-16, is strongly associated with oropharyngeal cancers and affects risk calculation significantly.

Q4: What are the limitations of this calculator?
A: The calculator provides statistical risk estimates and should not replace medical consultation. Individual risk may vary based on genetic factors and other health conditions.

Q5: How often should risk be reassessed?
A: Risk should be reassessed annually or when significant lifestyle changes occur (smoking cessation, alcohol reduction, etc.).
