Basal cell carcinoma epidemiology and demographics

The annual incidence of basal cell carcinoma in the United States is approximately 2.8 million which increases with increasing age. Men and white skinned people are affected relatively more, especially in states closer to the equator.

• The annual incidence of basal cell carcinoma in the United States is approximately 2.8 million.^[1]

• The incidence of basal cell carcinoma increases with age.^[2]
• The incidence rate doubles from 40 to 70 years of age.
• The incidence rate for those aged below 40 years is also increasing.

• Although both are affected, the incidence in males>females.^[3]
• This can be explained by gender differences in sun exposure habits and awareness of skin conditions.
• Men are also less likely to seek medical attention, allowing the more advanced development of skin cancer in comparison with women.

• Although it is observed in all races, dark skinned people are less commonly affected than fair skinned ones.
• Whites of celtic ancestry have the highest risk for basal cell cancer.
• Incidence is low in blacks, Asians, and Hispanics

• States closer to the equator, such as Hawaii and California, have a higher incidence of basal cell carcinoma compared to midwestern states^[4][5]

• An increasing incidence over time has also been noted in other countries, such as Canada, Finland, and Australia^[6][7][8]
• Basal cell carcinoma (BCC) is the most common skin cancer among the Far-east Asian race^[9]
• Majority of Far-east Asian race are Chinese (44.2%), Malays (32.6%), Bidayuhs (14.0%), and Ibans (6.9%)^[9]
