Cancer is the abnormal, uncontrolled growth of cells that, if left untreated, can ultimately lead to death. Most cancers take the form of tumors, although not all tumors are cancerous. A tumor is simply a mass of tissue that serves no physiological purpose. It can be benign, like a wart, or malignant, like most forms of cancer. Skin cancer is the most common cancer of them all.
Some good news is that most skin cancers are treatable when diagnosed early enough.
People with naturally dark skin pigmentation have a considerable degree of protection against skin cancer. People with fair skin, however, have lower natural protection against skin damage from the sun and a higher risk of developing certain types of skin cancer. Both sunburns and suntans can lead to skin cancer. Also, tanning salons do not offer a safe tan, as we might be mistakenly led to believe. These are usually found in areas of the body that are repeatedly exposed to the sun for long periods of time such as the face, neck, hands, and arms.
