The rising frequency of people getting skin cancer is attributed by cumulative sun exposure related to work and lifestyle shifts. Another contributing factor to the increase in the incidence rate is the continuous thinning of the ozone layer.
Other factors which participate in the development of skin cancer are tobacco smoking, ultraviolet radiation, human papillomavirus infection, chronic non-healing wounds, exposure to environmental carcinogens, artificial ultraviolet radiation from tanning beds and aging.
Skin cancer, which is the most commonly diagnosed type of cancer, can have different causes and may have unstable degrees of malignancy. This type of cancer can be divided into three classifications, namely, basal cell carcinoma, squamous cell carcinoma and malignant melanoma.
Clinically, basal cell carcinoma, which is the least lethal form of cancer, is characterized by an elevated, shiny, pearly lesion located especially on areas more frequently exposed to the sun such as the head, neck and shoulders.
The second type, the squamous cell carcinoma appears as a red, flaking, thickened area which can be sometimes firm, solid dome-shaped bump occurring on sun-exposed areas. The lesions may ulcerate and bleed when traumatized.
The deadliest form of skin cancer is melanoma. Melanomas are lesions with brown to black color.
Skin cancer can be significantly reduced if preventive measures are observed. These preventive measures include limiting sun tannig and mid-day exposure especially on 10 am to 3 pm, use of sunscreen lotion, avoiding tobacco products, avoid excessive exposure to harmful ultraviolet rays may it be from the sun or from artificial source such as tanning beds and wearing protective clothing when going outdoors.
