Awareness, knowledge, and attitude toward nonmelanoma skin cancer and actinic keratosis among the general population of western Saudi Arabia.

Abstract

This study evaluated the levels of awareness, knowledge, and attitude, including sun-protection habits, toward basal cell carcinoma and actinic keratosis among the Saudi population. A cross-sectional study was conducted among the general population of Jeddah, Saudi Arabia using a 12-item survey concerning the knowledge and awareness of basal cell carcinoma and actinic keratosis, as well as associated preventive measures. A Chi-square test was used to determine associations among variables. The majority of participants were unaware of basal cell carcinoma and actinic keratosis (80.7%), while 8.6% were aware of both, and 9.8% and 1% were aware of only basal cell carcinoma or actinic keratosis, respectively. The majority of participants who were educated up to high school level had no knowledge of either condition (96%, <i>P</i> < 0.0001). Among participants with high levels of awareness of basal cell carcinoma and actinic keratosis, medical practitioners were identified as the main source of information (72.5%, <i>P</i> < 0.0001, and 70.6%, <i>P</i> < 0.0001, respectively). The majority of participants whose knowledge of the relationship between sun exposure and skin cancer was insufficient also lacked sufficient awareness of either basal cell carcinoma or actinic keratosis (92.6%, <i>P</i> < 0.0001). The majority of participants (62.8%) declared using sunscreen "rarely". This study showed a low level of knowledge about the risks associated with sun exposure and suitable protection methods, with only a small fraction of participants declaring a regular use of sunscreen. Public education campaigns are required to increase the awareness of cancer risks and protection methods among the Saudi population.
