Finding Skin Cancer Early
When skin cancer is found and treated early, the chances of successful treatment are better. Get regular health checkups and see your doctor if you have any symptoms or are worried about your health.
If you have a higher than average risk, you may need to visit your doctor more often to check for skin cancer. Talk to your doctor about what can help find skin cancer early including checking your skin and having skin exams by a trained health professional.
The Abcdes Of Melanoma
The first five letters of the alphabet are a guide to help you recognize the warning signs of melanoma.
A is for Asymmetry. Most melanomas are asymmetrical. If you draw a line through the middle of the lesion, the two halves dont match, so it looks different from a round to oval and symmetrical common mole.
B is for Border. Melanoma borders tend to be uneven and may have scalloped or notched edges, while common moles tend to have smoother, more even borders.
C is for Color. Multiple colors are a warning sign. While benign moles are usually a single shade of brown, a melanoma may have different shades of brown, tan or black. As it grows, the colors red, white or blue may also appear.
D is for Diameter or Dark. While its ideal to detect a melanoma when it is small, its a warning sign if a lesion is the size of a pencil eraser or larger. Some experts say it is also important to look for any lesion, no matter what size, that is darker than others. Rare, amelanotic melanomas are colorless.
E is for Evolving. Any change in size, shape, color or elevation of a spot on your skin, or any new symptom in it, such as bleeding, itching or crusting, may be a warning sign of melanoma.
If you notice these warning signs, or anything NEW, CHANGING or UNUSUAL on your skin see a dermatologist promptly.

Skin Cancer Screening Studies
For people without a history of skin cancer in their families, no studies have been done to test the effectiveness of routine screening for melanoma. Periodic skin examinations are the key to diagnosing skin cancer at its earliest stage, when it is most easily cured. Most cases of basal cell carcinoma and squamous cell carcinoma first appear as changes in the skin, which, once noticed by the patient or primary care doctor, are then verified as skin cancer by a dermatologist after a skin examination and biopsy have been performed. Since basal cell and squamous cell carcinomas are almost always cured without specified screening, no studies have shown that such screening will improve the already high cure rates for those types of skin cancer.
Family history is a risk factor for melanoma. In addition, there is strong evidence that the risk of melanoma increases for individuals who have atypical moles or many common moles. Other melanoma risk factors include previous melanoma or non-melanoma skin cancers, skin that burns readily and fails to tan, freckling, blue eyes, red hair, and a history of blistering sunburns. To date, there is no evidence to show that screening individuals with any of these risk factors will reduce the number of melanoma deaths.

Possible Signs And Symptoms Of Melanoma
The most important warning sign of melanoma is a new spot on the skin or a spot that is changing in size, shape, or color.
Another important sign is a spot that looks different from all of the other spots on your skin .
If you have one of these warning signs, have your skin checked by a doctor.
The ABCDE rule is another guide to the usual signs of melanoma. Be on the lookout and tell your doctor about spots that have any of the following features:
- A is for Asymmetry: One half of a mole or birthmark does not match the other.
- B is for Border:The edges are irregular, ragged, notched, or blurred.
- C is for Color:The color is not the same all over and may include different shades of brown or black, or sometimes with patches of pink, red, white, or blue.
- D is for Diameter:The spot is larger than 6 millimeters across , although melanomas can sometimes be smaller than this.
- E is for Evolving: The mole is changing in size, shape, or color.
Some melanomas dont fit these rules. Its important to tell your doctor about any changes or new spots on the skin, or growths that look different from the rest of your moles.
Other warning signs are:
- A sore that doesnt heal
- Spread of pigment from the border of a spot into surrounding skin
- Redness or a new swelling beyond the border of the mole
- Change in sensation, such as itchiness, tenderness, or pain
- Change in the surface of a mole scaliness, oozing, bleeding, or the appearance of a lump or bump
Tests Are Used To Screen For Different Types Of Cancer When A Person Does Not Have Symptoms
Scientists study screening tests to find those with the fewest harms and most benefits. Cancer screening trials also are meant to show whether early detection helps a person live longer or decreases a person’s chance of dying from the disease. For some types of cancer, the chance of recovery is better if the disease is found and treated at an early stage.

Diagnosis Of Melanoma Skin Cancer
Diagnosis is the process of finding out the cause of a health problem. Diagnosing melanoma skin cancer usually begins with a visit to your family doctor. Your doctor will ask you about any signs or symptoms you have and do a skin exam. Based on this information, your doctor may refer you to a specialist, such as a dermatologist or surgeon.
The process of diagnosis may seem long and frustrating. Its normal to worry, but try to remember that other health conditions can cause similar signs and symptoms as melanoma skin cancer. Its important for the healthcare team to rule out other reasons for a health problem before making a diagnosis of melanoma skin cancer.
The following tests are usually used to rule out or diagnose melanoma skin cancer. Many of the same tests used to diagnose cancer are used to find out the stage .
Skin Exam And Physical
If youve been diagnosed with melanoma, youve already had a skin biopsy. This biopsy was taken when you had part of the suspicious spot removed. After it was removed, a doctor looked at the spot under a microscope to find out if it contained cancer cells. This is currently the only way to tell if someone has skin cancer.
After getting the diagnosis, the next step is to get a complete skin exam and physical.
During the physical, your dermatologist will feel your lymph nodes. This is where melanoma usually goes when it begins to spread. It usually travels to the lymph nodes closest to the melanoma.
If there is a risk the cancer could have spread, your dermatologist may recommend that you have a lymph node biopsy. If a sentinel lymph node biopsy is recommended, it can be performed at the time of your surgery for melanoma.
After the skin exam and physical, your dermatologist may recommend testing, such as a CAT scan, MRI, or a blood test. These can also help detect spread.

What’s The Point Of Routine Skin Checks
To help prevent a delayed diagnosis, it’s imperative to perform a routine skin check on your own at least once a month. “Skin checks are very easy to do and extremely important,”Elizabeth K. Hale, a board-certified dermatologist and a senior vice president of the Skin Cancer Foundation, tells Allure. “We have this unique ability to see skin cancer on the skin, and, therefore, we have this opportunity to detect cancers early, while they are still completely curable.”
A healthy you starts with you. No one is more intimate with your body than you are or could possibly have a greater awareness of what’s happening on your skin. Like a mirror, your skin is the reflection of what’s happening within. At the same time, there are eyes trained for detection and technologies available to catch concerning and cancerous lesions.

Diagnosis And Staging What It Means For You
How is melanoma diagnosed?
To diagnose melanoma, a dermatologist biopsies the suspicious tissue and sends it to a lab, where a dermatopathologist determines whether cancer cells are present.
After the disease is diagnosed and the type of melanoma is identified, the next step is for your medical team to identify the stage of the disease. This may require additional tests including imaging such as PET scans, CT scans, MRIs and blood tests.
The stage of melanoma is determined by several factors, including how much the cancer has grown, whether the disease has spread and other considerations. Melanoma staging is complex, but crucial. Knowing the stage helps doctors decide how to best treat your disease and predict your chances of recovery.
Check Your Skin Regularly
New moles mostly appear during childhood and through to the 30s and 40s, as well as during pregnancy. However, adults of any age can have new or changing spots. It is important to get to know your skin and check it regularly. In a room with good light, fully undress and use a full-length mirror to look closely at your:
- head, scalp, neck and ears
- torso on the ront, sides and back
- arms, hands, fingers and fingernails
- legs, toes, toenails and soles of the feet.
For areas that are hard to see, use a handheld mirror or ask someone to help.
Look for spots that are new, different from other spots, or raised, firm and growing. Even if your doctor has said a spot is benign in the past, check for any changes in shape, size or colour. If you notice a new or changing spot, ask your doctor to examine it.

What Happens During A Skin Cancer Screening
Skin cancer screenings may be done by yourself, your primary care provider, or a dermatologist. A dermatologist is a doctor who specializes in disorders of the skin.
If you are screening yourself, you will need to do a head-to-toe exam of your skin. The exam should be done in a well-lit room in front of a full-length mirror. You’ll also need a hand mirror to check areas that are hard to see. The exam should include the following steps:
- Stand in front of the mirror and look at your face, neck, and stomach.
- Women should look under their breasts.
- Raise your arms and look at your left and right sides.
- Look at the front and back of your forearms.
- Look at your hands, including between your fingers and under your fingernails.
- Look at the front, back, and sides of your legs.
- Sit down and examine your feet, checking the soles and the spaces between the toes. Also check the nail beds of each toe.
- Check your back, buttocks, and genitals with the hand mirror.
- Part your hair and examine your scalp. Use a comb along with a hand mirror to help you see better. It may also help to use a blow dryer to move your hair as you look.
If you are getting screened by a dermatologist or other health care provider, it may include the follow steps:
The exam should take 10-15 minutes.
What You Need To Know About Early Detection
Finding melanoma at an early stage is crucial early detection can vastly increase your chances for cure.
Look for anything new,changing or unusual on both sun-exposed and sun-protected areas of the body. Melanomas commonly appear on the legs of women, and the number one place they develop on men is the trunk. Keep in mind, though, that melanomas can arise anywhere on the skin, even in areas where the sun doesnt shine.
Most moles, brown spots and growths on the skin are harmless but not always. The ABCDEs and the Ugly Duckling sign can help you detect melanoma.
Early detection makes a difference
99%5-year survival rate for patients in the U.S. whose melanoma is detected early. The survival rate drops to 66% if the disease reaches the lymph nodes and27% if it spreads to distant organs.

Sentinel Lymph Node Biopsy
If melanoma has been diagnosed and has any concerning features , a sentinel lymph node biopsy is often done to see if the cancer has spread to nearby lymph nodes, which in turn might affect treatment options. This test can be used to find the lymph nodes that are likely to be the first place the melanoma would go if it has spread. These lymph nodes are called sentinel nodes .
To find the sentinel lymph node , a doctor injects a small amount of a radioactive substance into the area of the melanoma. After giving the substance time to travel to the lymph node areas near the tumor, a special camera is used to see if it collects in one or more sentinel lymph nodes. Once the radioactive area has been marked, the patient is taken for surgery, and a blue dye is injected in the same place the radioactive substance was injected. A small incision is then made in the marked area, and the lymph nodes are then checked to find which one became radioactive and turned blue. These sentinel nodes are removed and looked at under a microscope.
If there are no melanoma cells in the sentinel nodes, no more lymph node surgery is needed because it is very unlikely the melanoma would have spread beyond this point. If melanoma cells are found in the sentinel node, the remaining lymph nodes in this area are typically removed and looked at as well. This is known as a lymph node dissection .
Biopsies Of Melanoma That May Have Spread
Biopsies of areas other than the skin may be needed in some cases. For example, if melanoma has already been diagnosed on the skin, nearby lymph nodes may be biopsied to see if the cancer has spread to them.
Rarely, biopsies may be needed to figure out what type of cancer someone has. For example, some melanomas can spread so quickly that they reach the lymph nodes, lungs, brain, or other areas while the original skin melanoma is still very small. Sometimes these tumors are found with imaging tests or other exams even before the melanoma on the skin is discovered. In other cases, they may be found long after a skin melanoma has been removed, so its not clear if its the same cancer.
In still other cases, melanoma may be found somewhere in the body without ever finding a spot on the skin. This may be because some skin lesions go away on their own after some of their cells have spread to other parts of the body. Melanoma can also start in internal organs, but this is very rare, and if melanoma has spread widely throughout the body, it may not be possible to tell exactly where it started.
When melanoma has spread to other organs, it can sometimes be confused with a cancer starting in that organ. For example, melanoma that has spread to the lung might be confused with a primary lung cancer .
Biopsies of suspicious areas inside the body often are more involved than those used to sample the skin.

Our Skin Cancer Screening Guidelines
Our doctors do not recommend routine skin cancer screening. We do recommend lifelong dermatologic surveillance for patients with a personal history of melanoma. In addition, we recommend that individuals identified during routine care who meet any of the following criteria be considered for skin cancer risk assessment by a dermatologist:
- A family history of melanoma in two or more blood relatives
- The presence of multiple atypical moles
- The presence of numerous actinic keratoses
