Causes of Skin Cancer
Skin cancer is the uncontrolled growth of cells in the epidermis, the outer layer of skin. The mutation in the skin occurs as a result of unrepaired DNA damage that causes mutation. The two main causes of skin cancer are ultraviolet rays and tanning machines. Some of the major causes and risk factors associated with the development of cancer cells include
Sun Exposure and UV Rays
Exposure to the sun is associated with many skin issues; it causes most of the wrinkles and age spots on the face and can lead to serious consequences, including skin cancer. Exposure to the skin leads to many age spots and wrinkles. People usually consider a glowing complexion to be good for health but in actual sun rays speed up the effect of aging and chances of acquiring skin cancer.
Sun exposure causes a change in the skin, including the skin tone. Over time the ultraviolet rays of the sun cause damage to the fibers of skin called elastin. These fibers break down due to extreme exposure to the sun and lose their ability to go back into their original place, which results in the formation of bruises and tears, and it takes longer to heal.
The sun damage may not seem to be a big complication, but it can severely affect the body’s eyes and other parts. The sun exposure is linked with various skin issues, including precancerous and cancerous skin lesions formed as a result of the loss of the skin immune system.
Formation of benign tumors and coarse wrinkles, freckles, and discolored skin areas known as mottled pigmentation can also occur. The skin color becomes yellow, dilation of small blood vessels can also occur due to sun exposure.
The ultraviolet UV radiation coming from the sun is the leading cause of skin cancer; either UV rays are from the sun or a tanning machine. They are equally damaging to the skin. The exposure of skin to sunlight in winters has the same effect on the skin as that of exposure during summertime.
Increasing sun exposure mainly causes basal cell and squamous cell carcinoma and episodes of severe blistering and sunburns. Ultraviolet A and Ultraviolet B rays also affect eyes and the skin around the eyes, leading to eyelids’ cataracts and cancer.
