Cancer is considered as a disease that causes uncontrolled build up of cell in the human body caused by abnormalities in the system genetic make up. These abnormalities are formed from substances, radiation and/or other contagious agents. This growth of the cells then turns into what is considered a cancer that can spread throughout the body, although not every cancer are tumor based.
Skin cancers known to be the most commonly diagnosed cancer and can be identified by their malignant growth that can normally be found anywhere over the upper coating of the skin surface which makes it one of the easiest cancers to detect. The three main categories of skin cancers are malignant melanoma, non-melanoma skin cancers, Squamous cell carcinoma and Basal cell carcinoma being the most common but least fatal.
Malignant melanoma is the least common of the three skin cancers but is the most fatal once it begins to spread. On average It is responsible for about 3 out of every 4 every skin cancer related casualty and WHO (World Health Organization) reports about 48,000 Malignant melanoma related fatalities worldwide per annum. It is frequently found in Caucasian men who dwell within very sunny geographic locations. The remedy for this skin cancer is usually done through radiation treatment, chemo and immunotherapy or surgical removal of the skin tumor.
Non-melanoma is a very rare case of skin cancer that probably noted for maybe 1% of individuals diagnosed in the UK. They are Sarcoma, Kaposi's sarcoma, T Cell lymphoma of the skin and Merkel cell carcinoma than can be treated in different ways from the other three most common skin cancers. Non-melanoma cancers can also develop from a mole.
The Squamous cell skin cancer are more popular than malignant melanoma and metastasize more than the Basal cell cancer.
It is formed on skin cells called keratinocytes seen in the upper coating of the epidermis and can also spread to deeper layers of the skin and into the lymph nodes and other organs which can trigger secondary cancers such as sarcoma, Merkel cell carcinoma and T cell lymphoma of the skin. The Squamous skin cancer can also be formed from scars, burns, or ulcerations of the skin that were inflicted earlier on in life. This skin cancer accounts for approximately 1 in 5 skin cancer cases.
The basal cell cancer mostly affects the areas of the skin that is more commonly exposed to sunlight like the face and hands but can also spread to other areas of the skin such as the back and lower leg areas of the skin even though this rarely occur(s). The Basal cell cancer is in most cases diagnosed when a person is in the middle or old age of an individual's life however, it is the easiest skin cancer to treat through surgery or radiation methods.
If this skin cancer is left untreated it can develop into a rodent ulcer which is a deep ulcer in the skin that expands into and devour the skin tissues that surround it. Having the Basal cell cancer in the past increases a person's chances of getting the cancer another time.
