Skin Cancer Risk Factors in New Mexico
UV radiation is the primary environmental risk factor for skin cancer. While the UV index in New Mexico is only one factor, understanding cumulative exposure is important. Key risk factors include:
- Cumulative UV exposure — total lifetime sun exposure, especially sunburns before age 18
- Skin type — fair skin (Types I-II) has significantly higher risk
- Geographic location — New Mexico's high UV levels increase baseline risk compared to northern states
- Altitude — higher elevations increase UV exposure significantly
- Outdoor occupation/hobbies — agricultural workers, construction workers, golfers, runners, and beach visitors accumulate more exposure
- Tanning bed use — artificial UV exposure dramatically increases risk
The American Academy of Dermatology recommends annual skin checks for everyone, with more frequent screenings for those with multiple risk factors. Early detection dramatically improves outcomes for all types of skin cancer.
