Melanomas can develop anywhere on your body. Because of this, we recommend that men and women of all ages should get to know every square inch of their skin. The more familiar you become with your moles, freckles, and birthmarks, the more likely you’ll be able to identify changes or new growths. So any melanomas can be treated quickly and successfully.
Melanoma can often be found early when its easiest to be cured. Detection starts with self-exams and exams by a healthcare professional.
Becoming familiar with your skin involves performing monthly self-exams to inspect your skin for any signs of skin cancer. It’s best to keep a record of your findings on a body map, which is a diagram of the body where you make marks that correspond to the marks on your skin. On the body map, you will make these marks, and then make a record of the mark’s color, size, shape, and the date found. Use the same map each month so that you are able to track any changes in existing spots and easily identify new spots.

With each self-exam, you’ll become more familiar with what is normal for your skin. Any new spots on the skin, along with any that change in size, shape, or color, should be seen by a doctor promptly.
If you are prone to freckles or moles, you may find it harder to determine which spots are normal and which ones require further evaluation. There are common signs that can help you determine if your spot is troublesome.
These are commonly referred to as the ABCDE Rule and include:

Not all skin cancers follow these rules, but many do. When in doubt about any mark on your skin that seems unusual, be cautious, and have it looked at by a healthcare professional.
Sometimes, doctors and other healthcare professionals will perform a skin exam as part of a routine health check-up.
If your primary doctor finds any irregular moles or suspicious areas, he or she may refer you to a dermatologist. Dermatologists can also do regular skin exams.
If your doctor finds an abnormal spot on your skin, he or she will usually examine it and perform tests. These tests are used to confirm if melanoma, another type of skin cancer, or some other skin condition is present. If melanoma is found, additional tests may be done to determine if it has spread to other areas of the body.
During a physical exam, your doctor will discuss your symptoms in detail to get a better idea about your situation. You may also be asked about your possible risk factors for melanoma skin cancer. Risk factors such as your history of tanning and sunburns, and if you or anyone in your family has had a melanoma or other skin cancers are important to disclose to your doctor.
Your doctor will note the shape, color, size, and texture of any area(s) that are suspect, and whether it is bleeding, oozing, or crusting. He or she may also check the rest of your body for moles and other spots that could be related to different types of skin cancer or another type of skin condition.
Melanoma often goes to nearby lymph nodes first when it spreads. Therefore, it is also likely that your doctor will check the lymph nodes around the neck, underarms, or groin-area near the abnormal skin.
If the doctor suspects melanoma, a biopsy will be needed. It is the only way to make a definite diagnosis. A biopsy can usually be done in the office using local anesthesia. A pathologist examines the biopsied tissue to check for the presence of cancer cells.
If the growth is too large to be removed entirely, the doctor removes a sample of the tissue. The doctor will never shave off or cauterize a growth that might be melanoma.
There are several different types of biopsies that may be performed. The four common types of biopsies include:
If you receive a diagnosis of melanoma, the next step is to determine the extent (stage) of the cancer. Once your doctor knows the melanoma stage, your treatment team can develop an appropriate plan specifically for you.
