There are three types of skin cancer: melanoma, basal cell carcinoma, and squamous cell carcinoma.
The squamous and basal cell variety are the most common and also called non-melanoma cancer.
Basal cell and squamous cell carcinoma are the types of cancers most often associated with the sun's ultra violet rays.
Basal cell carcinoma (BCC) is
a small firm lesion
• it is flesh colored and dome shaped
• the edges of the lesion are raised
• it has milky white or pearly borders
• you can see tiny blood vessels within it
• it can look like a pimple that won’t heal which shows bleeding within the lesion or it may be ulcerated
These legions are very destructive when they surface around the eyes or nose.
Fibrosing (bcc) have fibrous stroma running through them. They can often be yellowish in colour and look like a scar.
Superficial (bcc) are usually found on the trunk and grow down into the dermis of the skin. They can look like eczema or psoriasis.
FIBROEPITHELIOMA OF PINCUS grows in areas like the groin and may not be associated with sun exposure.
Squamous cell carcinoma are reddened, scaly or plaque-like areas that:
• are slightly elevated
• can become ulcerated
• turn into a hard pale pink to white nodule
• can develop a scaly crust or a wart-like surface
• come from old scars, change colours, bleed, leak, or become painful
• appear on face, neck, ears, back of hands, forearms,, and legs
Depending upon the the type of carcinoma, treatment would include: drug therapy such as Adara skin cream, Curettage and Electrodesiccation, surgery, radiation, and chemotherapy.
Basal cell carcinoma is the most common form of skin cancer in Canada and the least dangerous, squamous cell carcinoma is the second most prevalent form of skin cancer in Canada.
The researchers from the University of Alberta surveyed the rates of these cancers in over 100, 000 people. They found that basal and squamous cell carcinoma was previously on the rise in Canadian women but declined within the last decade.
These skin cancers in men leveled off in 2001, and has declined by 1 percentage point each year ever since.
Canadians, including Montrealers are listening to the warnings and are protecting their skin while they are out in the sun.
