Like all cancers, skin cancer is caused when the cells are exposed to some external environmental condition. This causes the cells, or more specifically the genes in the cell to mutate and become known as a oncogene. An oncogene promotes tumor growth.

In many cases of cancer it is not always clear what the environmental condition or conditions may be. In fact, it may not be just one condition that promotes cancer growth but a multitude of them making it harder to prevent the development of the disease. In the case of skin cancer, the environmental condition is thought to be exposure to ultraviolet radiation. And the most common source of ultraviolet radiation that most people are exposed to is sunlight.

However, some people can spend more time in the sun than others without developing skin cancer. Their skin is not as sensitive to the sun. This is because they have more melanin in the body. Amongst many other functions, melanin makes the skin go brown when exposed to the Sun. This is the body's natural method of protecting skin cells. This is the tan that many people like to develop as they see it as an indication of health and vitality.

People with pale skin, fair or red hair and light colored eyes have less melanin than people with darker complexions. They are more sensitive to the sun. Their skin will most likely burn than go grown in the sun. Sunburned skin is painful but it is also an indication that your skin has been exposed to too much UV rays. Prolonged exposure to the sun or constant sunburn will facilitate the development of skin cancer.

Another factor that can increase the chances of developing skin cancer is any family history of the disease.

The effects of skin cancer vary depending on the type of carcinoma. Basal cell carcinoma is the most common type of skin cancer. It is normally found on areas of the body directly exposed to the sun. It is generally a mark or spot on the skin that could be brown or red. In most cases it will not spread from the original location.

Squamous cell carcinoma is another form of skin cancer that is normally found on parts of the body that are exposed to sunlight. Again, it does not always spread from the original location but is more likely to spread than basal cell. If it does spread it will normally only spread to surrounding cells. So if it is on the surface of the skin you will notice a mark that is brown or red that starts to get larger over time.

Melanoma are the third type of skin cancer. They are the most serious and rarest form of skin cancer. They can appear anywhere on the body and are not uncommon in parts of the body that are not normally exposed to the sun, like the feet. They could take the form of a brown spot that gets larger or simply a lump under the skin.

A Melanoma can be malignant, meaning that they will continue to grow in a random fashion at an uncontrolled rate. This becomes a problem when the melanoma becomes invasive. This means it will interfere with surrounding tissues and organs to the extent that it destroys them or stops them functioning properly.

If melanoma spreads throughout the body it can be very hard to treat.

The best way to guard against skin cancer is to limit your exposure to sunlight and protect your skin when in the sun. Also monitor any unusual skin blemishes or lesions or unusual lumps. Get your skin checked out from time to time by a skin specialist. Avoid other things that can expose you to UV rays.
