Cancer is the condition in which the cells multiply profusely without any control over it. Skin cancer is the malignant growth on skin. 90% of the skin cancers are caused due to prolonged exposure to UV rays of sunlight.

- Squamous cell carcinoma
- Malignant melanoma
- Basal cell carcinoma: these are the most common type of skin cancer. They are present on the sun exposed areas of skin, commonly seen on face. They are easily treated with radiation therapy. Death is very rare in this type of skin cancer.
- Squamous cell carcinoma: They metastasize more frequently than basal cell carcinoma as they metastasize less frequently.
- Melanomas: melanomas are responsible for 75% of all skin cancer related deaths. These are the least common of the three types. But most fatal once it spreads. They metastasize frequently. These 3 types are most common skin cancers.

Thank you for your blog. I am four days away from learning my biopsy results from a suspicious spot on my face. From your description here the lesion on my face sounds an awful lot like basal cell carcinoma. It is a relief to know that it is one of the lesser evils in skin cancers, none the less an unsettling potential diagnosis. I wish that providers would take the time to talk with clients at least about potential biopsy results, treatments and outcome. Better this than letting their clients lose to seek information and solace in websearches on line. I thank you again for your devotion for offering information to the public.
