Some drugs have a photosensitizing effect. Properties of natural or artificial light that may abnormally affect people include: Timing of light (upset of normal circadian rhythms, seasonal affective disorder, sleep disorders) Intensity of light (photophobia, sunburn, skin cancer) [1] [2] [3] Wavelength of light (in lupus, urticaria)
The cancerous skin lesions refer to damaged cutaneous tissues with risks of further developing into skin cell carcinoma. [31] Skin carcinoma, or skin cancer, is very common in sun-radiation-abundant areas. The over-exposure to sunlight is the most prevalent cause that leads to Actinic keratosis (AK), a common cancerous cutaneous lesion.

Skin cancer is the most common form of cancer, globally accounting for at least 40% of cancer cases. [5] [20] The most common type is nonmelanoma skin cancer, which occurs in at least 2–3 million people per year. [6] [21] This is a rough estimate; good statistics are not kept. [1]
Overexposure to ultraviolet radiation is known to cause skin cancer, [19] make skin age and wrinkle faster, [20] mutate DNA, [21] and impair the immune system. [22] Frequent tanning bed use triples the risk of developing melanoma, the deadliest form of skin cancer, according to a 2010 study.
Cancer rates in men are projected to jump by 84 percent from 2022 to 2050, while cancer deaths are expected to increase by 93.2 percent over the same time frame, according to the peer-reviewed study.
