Types Of Skin Cancer
Basal Cell Carcinoma
About two thirds of all skin cancers are basal cell carcinomas (also called basal cell cancers). Basal cell cancers usually develop on areas exposed to the sun, especially the head and neck.
They can appear as raised areas (like this one), and can be pale, pink, or red. They may have one or more abnormal blood vessels.
Ulcerated Basal Cell Carcinoma
Over time, the top layer skin may begin to break down. This is called ulceration. Ulceration causes the center of the lesion to collapse.
Squamous Cell Carcinoma
About one third of all skin cancers are squamous cell. Squamous cell skin cancers tend to grow slowly and can almost always be cured if found early.
But if not treated, these cancers can grow into nearby areas or even spread to other parts of the body, where they can be much harder to treat.
Melanoma is much less common than basal cell and squamous cell skin cancers and makes up about 1% of skin cancers but is by far the most dangerous.
Like this one, melanomas may have different colors and jagged borders. They may not be round, and one half might not look like the other half.
