Causes and Risk Factors
Actinic keratosis
Actinic keratoses are primarily caused by cumulative UV exposure from activities such as sunbathing, using tanning beds, outdoor work, recreational activities, and living in sunny climates. Other contributing factors include phototherapy and ionizing radiation. Individuals with fair skin, red or blonde hair, blue eyes, and those who burn easily are at higher risk. AK is more prevalent among older adults and those with compromised immune systems.
Risk Factors
Several factors increase the likelihood of developing actinic keratoses:
– Genetic Predisposition: Individuals with fair skin, light-colored eyes, and a tendency to burn rather than tan are at higher risk.
– Age: People over 40 years old are more susceptible.
– Sun Exposure: Extensive sun exposure or a history of sunburn increases risk.
– Geographic Location: Living in sunny regions heightens the likelihood of AK.
– Outdoor Occupations: Jobs that require prolonged outdoor activity can increase risk.
– Immune System: A weakened immune system, due to disease or medication, can make one more prone to developing AK.
