Is It a Melanoma?
Melanocytic skin cancers include melanoma in situ and malignant melanoma, and can develop from a “dysplastic” mole. Melanoma skin cancer can be the deadliest, but is often preventable.

Ask the ABCD’S.
A. Asymmetry – Is the left half different from the right half?
B. Border – Does the border have uneven jagged edges?
C. Color – Are there two or more colors?
D. Diameter – Is the diameter greater, larger than six mm?

Signs & Symptoms
1. Is there a family history of melanoma?
2. Do family members have many moles?
3. Ever sunburned or used a tanning bed?
4. Do any spots show signs or symptoms?
Bleeding? Itching? Scaling? Growing? Changing Color?
Two ABCD’S positive out of five may be a sign your mole needs a biopsy.
Doctor, is it skin cancer?
This is an important question, especially if you have fair skin and have tanned or sunburned. Skin cancer is the number one cancer in humans, far exceeding the total of all other cancers. With diminishing ozone, one in six Americans will get skin cancer in his or her lifetime. “Doctor, I haven’t been in the sun for 30 years.”
The fact is, skin cancer may not appear until 10, 20, 30, or 40 years after a sunburn. How can you tell if you skin cancer? Skin cancer usually begins as a small non-healing spot on the skin.
The spot does not hurt, but may itch or bleed.

Many do not see a doctor until pain or bleeding occurs, or until the spot has grown into a larger tumor. A simple way to understand skin cancer is to categorize it as either 1. Non-melanoma skin cancer or 2. Melanoma type skin cancer.
Is it AK, BCC, or SCC?
Non-melanoma skin cancers usually grow from precancers on sun exposed sunburned skin, and can form Basal Cell Carcinoma (BCC) and Squamous Cell Carcinoma (SCC).
AK: Actinic Keratoses are precancerous scales that grow on sun damaged skin. If left untreated, AK’s can become more aggressive BCC or SCC skin cancers.
BCC is a low-grade cancer that can cause severe facial disfigurement or loss of an eye, nose, or ear if not treated. SCC is a skin cancer that can spread to your lymph nodes if not treated. A simple ounce of prevention is worth a pound of cure.
Are you at risk?
Are you at risk for skin cancer? Should you be concerned? Finding out is easy to do. Here are six easy questions to ask and see if you are at risk for skin cancer.
1. Do you have a persistent non-healing sore on your skin?
2. Do any of your relatives have a history of skin cancer?
3. Have any of your moles changed in color, shape, size?
4. Are your eyes blue, green, hazel?
5. Is your skin fair or light in color?
6. Have you ever been sunburned?
If you answered “yes” to any, you are at risk and must get checked!
