Skin cancer, I think each of us are very family with this noun, however, how many of us know the real symptom and what it is? Skin cancer is the most common form of human cancer. It is estimated that over one million new cases occur annually. The annual rates of all forms of skin cancer are increasing each year, which represent a growing public concern. What’s the most horrible thing is it has also been estimated that nearly half of all Americans who live to age 65 will develop skin cancer at least one. Actually, the most common warning sign of skin cancer is a change in the appearance of the skin, such as a new growth or a sore that will not heal. The following three are the three different conditions of the skin cancer, which have been ranked from the least to the most dangerous.
1. Basal cell carcinoma or basal cell carcinoma epithelioma
2. Squamous cell carcinoma or the first stage of which is called actinic keratosis
The two most common forms of skin cancer are basal cell carcinoma and squamous cell carcinoma. In fact, these two are also referred to as non-melanoma skin cancer. Melanoma is generally the most serious form of skin cancer because it tends to speard throughout the body quickly. Skin cancer is also known as skin neoplasia. So, what is basal cell carcinoma?
Among the all three types of skin cancer, Basal cell carcinoma is the most common form of skin cancer and accounts for more than 90% of all skin cancer in the U.S. These cancers almost never spread to other parts of the body. However, they can cause damage by growing and invading surrounding tissues. What are risk factors for developing basal cell carcinoma?
Light-colored skin, sun exposure, and age are all important factors in the development of basal cell carcinomas. People who have fair skin and are older have higher rates of basal cell carcinoma. There are approximate twenty percent of these skin cancers, however, occur in areas that are not sun-exposed, such as the chest, back, arms, legs, and scalp. However, the face remains the most common location for basal cell lesions. Weakening of the immune system can also promote the risk of developing basal cell carcinoma. Additionally, other risk factors include
1. Exposure to sun
There is evidence that basal cell carcinoma is promoted not by accumulated sun exposure but by intermittent sun exposure like that received during vacations, especially early in life. 2. Age
Most skin cancers appear after age 50, but the sun’s damaging effects begin at an early age. So, protection should start in childhood in order to prevent skin cancer later in life
3. Exposure to ultraviolet radiation
Exposure to ultraviolet radiation in tanning booths. Tanning booths are very popular, especially among adolescents, and they even let people who live in cold climates radiate their skin year-round.
4. Therapeutic radiation
Such as that given for treating other forms of cancer.
