Cancer is a disease that manifests itself in different parts of the body. There are many types of cancer like blood, skin, uterine and lung cancer. Of the many types of cancer, the form of cancer which is most avoidable today is skin cancer. Skin cancer starts with excessive exposure to sun’s UV rays.
Skin cancer exists in different forms while affecting different parts and exhibiting different symptoms. There are basically three skin cancer types that have different symptoms:
1. Squamous cell carcinoma is one of the three skin cancer types that can usually found in places of the body that are exposed to the sun. This includes the ears, face and mouth. One symptom of this form of skin cancer is a bump that tends to turn into an open sore. This sore is a form of ulceration that is reddish with a flat spot that is sometimes crusty and comes with a bump grows larger and a sore that does not heal. If left untreated, this bump can spread quickly to other parts of the body like the nerve routes, bloodstream and lymphatic system.
2. Basal cell carcinoma is the second in skin cancer types and accounts for about 75% of the diagnosed cases of skin cancer. Basal cell carcinoma is therefore the most common form of skin cancer. Basal cell carcinoma usually occurs on the face, neck and hands. It is a highly treatable form of cancer that rarely spreads to other parts of the body. Symptoms of this skin cancer type includes a sore that oozes or bleeds, an irritable area of red, a yellow or white area that looks like a scar and a pink, pearly bump.
3. The third of the skin cancer types is melanoma. This is considered to be the most dangerous and deadly form of skin cancer. Melanoma can occur on any part of the body, where the hands, legs and trunk are the most commonly affected areas of the body. It is only when melanoma is detected early that it is treatable. The symptoms for melanoma include a mole, freckle or any other new or existing spot on the body that tends to change in color, size, shape or appearance. Sometimes these spots may take an irregular outline, so that it exists in more than one color.
The best defense to adopt for preventing skin cancer is to avoid as much excessive exposure to the sun as possible. So the best thing to do is to wear a sunscreen when outdoors, and wherever possible, to stay in shady areas.
