Skin cancer, although it seems small, can be quite deadly if it is not caught on time. As for how it develops, the cancer develops when DNA is damaged beyond repair. The cells that are damaged then grow and divide at a rate that is uncontrollable. When this damage occurs in the skin and the cells grow and divide uncontrollably, skin cancer is the result. The damaged cells will continue to multiply and that will cause a tumor.
The cancer usually develops in the epidermis, which is the outermost skin layer. That is why the skin cancer tumor is usually quite visible. This is why skin cancer is usually detectable in the early stages.
Sun exposure seems to be the main reason why skin cancer develops. The American Cancer Society has stated that most of the 1 million cases of skin cancer that are diagnosed each year could be prevented with proper sun ray protection. It is the UV rays from the sun that causes DNA to become damaged. The body is such an amazing machine that it can usually repair this DNA damage, but there is a time in which that repair may not take place. Cumulative sun exposure can cause this and later lead to skin cancer. This is why some individuals do not develop skin cancer until 30 or 40 years after they have had the extensive sun exposure.
What do the different types of skin cancer look like?
There are different types of skin cancer that a person can acquire. There are actually 3 main types. These 3 types account for all of the cases of skin cancer. What makes them different is the fact that these 3 cancers start in different skin cells. This is how each cancer gets their name; they are named based on the cell that they develop from. It is also important to note that there are two classes of skin cancers. The first class is nonmelanoma skin cancers and the second is melanoma skin cancers. Melanoma is the deadliest type of skin cancer.
Here are the three different types:
• Basal Cell Carcinoma – This is the most common form of skin cancer. More than 1 million people in the United States develop this form of cancer, which also means around 80% of all skin cancers are of this type.
This type of skin cancer develops in the basal cells. These are cells that are present in the lowest layer of the epidermis. It can take on several forms. It can appear as a pearly nodule or it can appear as a nodule that is translucent. The sore may continuously heal and then re-open. The growth may also be elevated and slightly pink. Some individuals may even notice a waxy scar or a reddish patch of skin that simply looks irritated.
