What Causes Skin Cancer?

However it has a noticeably lower incidence of death because of the probability that it will be identified in the early phases of the disease. Melanoma is the most destructive kind of skin cancer but is less common than the two other forms of this disease. In many manifestations of the disease, the cancer does not always spread immediately or at all.

What causes Skin Cancer?


There are quite a few known causes of skin cancer. The most widely acknowledged cause is over exposure to harmful ultraviolet rays or sunlight. The list below highlights some of the main causes:


• Suffering from any deficiency of the immune
system, that is having a disease that subjects you to lessened immune system function, will elevate the risk for developing skin cancer. This decrease in the ability of the immune system to function may also be as a result of consuming drugs to fight an autoimmune disease or after having an organ transplant. These drugs will be used to lower the immune system response in the case of autoimmune diseases that promote the immune system to attack its own cells and organs, for example in people with lupus. These drugs are also used after an organ transplant to make certain that the body will not reject the newly transplanted organ.
• Being exposed to abnormally high levels of X-rays may induce the development of skin cancer.
• Using tanning booths to maintain an artificial tan has been broadly accepted as a likely cause of the disease.
• There are some chemicals that have been found to incite the development of skin cancers. These will usually include polycyclic aromatic hydrocarbons and arsenic. It is speculated that polycyclic aromatic hydrocarbons may possibly be inhaled because of low levels of contamination in the air, consumed in foods and by making contact with any surface that is saturated with the chemical.
• Some people are said to be at a greater risk, such as lighter skinned people, people with blond or red hair and green or blue eyes. Having freckles or being prone to sun burn may also heighten a person's risk for developing this type of cancer.
• Having a genetic irregularity that does not allow the development of pigment can increase the risk for the disease. These disorders include albinism and xeroderma pigmentosum.
• If an individual has already had skin cancer the risk is increased.
• If you had at least one very extreme case of sunburn in childhood the risk for developing this type of cancer is higher.
• Having a family history of the disease is also a well known risk factor.
• If you have several moles these can become cancerous growths on the skin's surface. Some individuals choose to have any moles removed to decrease the likelihood that they will develop into cancerous growths
