Actinic Keratosis



Actinic Keratosis is a premalignant lesion which if left untreated may become a Basal Cell Carcinoma or Squamous Cell Carcinoma. Actinic Keratosis are usually found on sun exposed areas of skin.


Basal Cell Carcinoma




Basal Cell Carcinoma is the most common type of skin cancer. It usually occurs on areas of the skin that have been in the sun, most often the nose. Often Basal Cell Skin Cancer appears as a small raised bump that has a smooth, pearly appearance. It may also appear  like a scar that is flat and firm to the touch. Basal cell carcinoma may spread to tissues around the cancer, but it usually does not spread to other parts of the body.



Squamous Cell Carcinoma




Squamous Cell Carcinoma occurs on areas of the skin that have been in the sun, such as the ears, lower lip, and the back of the hands. Squamous cell carcinoma may also appear on areas of the skin that have been burned or exposed to chemicals or radiation. Often this cancer appears as a firm red bump. Sometimes the tumor may feel scaly or bleed or develop a crust. Squamous cell tumors may spread to nearby lymph nodes.






Malignant Melanoma is a form of skin cancer that arises from the cells that produce pigment. Melanoma may begin in association with a mole. Although most moles are benign, some may go on to become malignant melanomas. Exposure to sun and sunburn are the main environmental agents that cause melanoma. Melanoma is a very serious skin cancer and must be detected early to prevent spread to lymph glands and distant organs.

Certain factors make one at higher risk to develop malignant melanoma. Risk for developing malignant melanoma is higher in people with a high number of atypical appearing nevi known as Dysplastic Nevi. Risk is even higher in people with a family histtory of dysplastic nevi and malignant melanoma. People with weakened immune systems as a result of certain cancers, drugs or by HIV are at increased risk for developing malignant melonama.


Dysplastic Nevi



Dysplastic Nevi are benign but may undergo change and become Malignant Melanomas. For this reason these atypical moles should be excised.
