What The Doctor Is Looking For
During a skin cancer screening, your doctor is checking for the ABCDEs of each mole, which are all possible signs of skin cancer:
- Asymmetry: Not the same shape on both sides
- Border irregularity: Ragged or blurred edges
- Color: Different shades of tan, brown, or black
- Diameter: Larger than 1/4 inch
- Evolving: Changes over time
Your doctor will also check for actinic keratosis, skin changes caused by sun damage that, without treatment, can turn into cancer.

Lab Tests Of Biopsy Samples
Samples from any biopsies will be sent to a lab, where a doctor called a pathologist will look at them under a microscope for melanoma cells. Often, skin samples are sent to a dermatopathologist, a doctor who has special training in looking at skin samples.
If the doctor cant tell for sure if melanoma cells are in the sample just by looking at it, special lab tests will be done on the cells to try to confirm the diagnosis. These might include:
- Fluorescence in situ hybridization
- Comparative genomic hybridization
- Gene expression profiling
If melanoma is found in the samples, the pathologist will look at certain important features such as the tumor thickness and mitotic rate . These features help determine the stage of the melanoma , which in turn can affect treatment options and prognosis .
Excisional And Incisional Biopsies
To examine a tumor that might have grown into deeper layers of the skin, the doctor may use an excisional biopsy.
- An excisional biopsy removes the entire tumor . This is usually the preferred method of biopsy for suspected melanomas if it can be done, although this isnt always possible.
- An incisional biopsy removes only a portion of the tumor.
For these types of biopsies, a surgical knife is used to cut through the full thickness of skin. A wedge or sliver of skin is removed for examination, and the edges of the cut are usually stitched together.

Reasons To Get An Annual Skin Cancer Check Done
The word cancer can strike fear into even the bravest of us. When hearing about skin cancer, many people are quick to think that it is just a matter of time before dealing with this disease. However, you can do some simple things on an annual basis to make sure your risk for developing skin cancer is low. The first and foremost thing is to get a skin check done. Skin checks are essential because they can catch any changes in your skin before they turn into something more dangerous. To get yours done today, .
For those who know what to look out for, there are several other reasons why annual checks should become part of everyones routine health care regimen.

Medical History And Physical Exam
Usually the first step your doctor takes is to ask about your symptoms, such as when the mark on the skin first appeared, if it has changed in size or appearance, and if it has been painful, itchy, or bleeding. You may also be asked about your possible risk factors for melanoma skin cancer, such as your history of tanning and sunburns, and if you or anyone in your family has had melanoma or other skin cancers.
During the physical exam, your doctor will note the size, shape, color, and texture of the area in question, and whether it is bleeding, oozing, or crusting. The rest of your body may be checked for moles and other spots that could be related to skin cancer .
The doctor may also feel the lymph nodes under the skin in the neck, underarm, or groin near the abnormal area. When melanoma spreads, it often goes to nearby lymph nodes first, making them larger.
If you are being seen by your primary doctor and melanoma is suspected, you may be referred to a dermatologist, a doctor who specializes in skin diseases, who will look at the area more closely.
Along with a standard physical exam, many dermatologists use a technique called dermoscopy to see spots on the skin more clearly. The doctor uses a dermatoscope, which is a special magnifying lens and light source held near the skin. Sometimes a thin layer of alcohol or oil is used with this instrument. The doctor may take a digital photo of the spot.

How Is Skin Cancer Diagnosed
A skin biopsy is needed to diagnose skin cancer. Your doctor removes a sample of skin tissue, which is sent to a laboratory. In the laboratory, a pathologist studies the sample under a microscope. The pathologist looks for abnormal cells that indicate cancer. If it is cancer, the biopsy sample provides important information about the cancer stage.
Lymph node biopsy is done when there are signs of advanced melanoma, such as:
- Swollen, hard, and enlarged lymph nodes.
- Mid-thickness tumor , even without lymph node symptoms.9
Imaging tests are done for advanced melanoma. The purpose is to see whether the cancer has spread to distant parts of the body. Melanoma is most likely to spread to distant lymph nodes, lungs, liver, brain, and bones.10 These areas may be evaluated using:
- Computed tomography , alone or with positron emission tomography
- Chest x-ray
- Magnetic resonance imaging
- If distant metastases are found, a blood test may be done to check your lactate dehydrogenase levels. LDH is an enzyme found in the blood. The results of this test are used to classify Stage IV cancer. High LDH is a sign of cancer that is harder to treat.5

Can Blood Tests Or Scans Detect Skin Cancer
Currently, blood tests and imaging scans like MRI or PET are not used as screening tests for skin cancer. However, some national studies are underway to determine if concentrations of skin cancer DNA can be detected by blood tests. Occasionally, imaging detects signs of advanced disease. Sometimes, skin cancer that has spread to internal organs is detected incidentally when a patient is undergoing an imaging study such as MRI or PET scan for unrelated conditions.

Why Do I Need A Professional Skin Check
Doctors use tools and techniques to examine skin thoroughly, beyond what the naked eye can see. And melanomas that are detected and treated early are cured in 90% of cases. So, in addition to self-checking regularly you should have a professional skin check once a year. It is also important to get a professional skin check by a doctor if anything having your annual skin check.
To Protect Yourself From Future Cancers
Basal cell carcinomas do not typically spread to distant organs as melanoma does. But because they grow slowly, they tend to recur over time. If left untreated, recurrent lesions will eventually cause cosmetic problems and scarring. Fortunately, treatment options include surgery and radiation therapy. They work very well when caught before spreading too much. Because of their low rate of metastasis, BCCs make excellent candidates for less invasive treatments. By catching them early enough, you can avoid undergoing more aggressive procedures later down the line.

Skin Cancer Screening Program
The free skin cancer screening program is the AAD’s longest-standing public health program. Since its inception in 1985, dermatologists have conducted more than 2.8 million free skin cancer screenings with more than 278,000 suspicious lesions detected, and more than 31,500 suspected melanomas. Millions of people have been educated about the importance of sun protection and early cancer detection through the skin cancer screening program. As a result, countless lives have been saved by identifying melanomas in their earliest, most treatable stage.
1 in 5 Americans will develop skin cancer in their lifetime. Find support and encouragement from skin cancer patients and their families who have chosen to share their stories.
Skin Cancer Is On The Rise
This year, 300 practitioners are participating in this prevention and screening week. While many French people will be able to benefit from a screening consultation, many will also take it too late. For these last ones, the organizers then advise to go from time to time on the appointment-making site on which new slots are posted regularly.
According to the League against cancer, skin cancers are today among the most frequent and 60,000 new cases are diagnosed each year, including nearly 7,400 melanomas. Skin cancer is one of those that is still on the rise in France, even though research against cancer is making many advances every year.

Know Your Risk Factors
In terms of skin cancer, the population at the highest risk is anyone with fair skin, often called Skin Type 1 and Skin Type 2 . These people tend to have a hard time tanning and burn easily, and are Caucasian with blue eyes, light hair, and freckles. âNo matter what, they should get annual skin checks,â says Dr. Khorasani.
As for the rest of the population? Skin cancer risk is based on a slew of other risk factors, the biggest of which is a history of skin cancer yourself. Other risk factors: a history of severe sunburn, a history of using tanning beds, and a sibling or parent who has a history of skin cancer, says Dr. Khorasani. Research also suggests that having more than 11 moles on one arm could put you at an increased risk for skin cancer.
âIf someone has a history of skin cancer or has a first-degree relative with a history of skin cancer, they should be coming for screenings every six to 12 months,â says Dr. Glashofer. Ditto if you have a history of sunburns or using tanning beds, both of which put you at a higher risk of skin cancer than someone who simply has fair skin, says Dr. Khorasani.
Then, consider factors like your job or your general health. Studies show that pilots have more instances of skin cancer than the rest of the population. And Dr. Glashofer notes that gigs that keep you outdoors can increase risk too, thanks to increased exposure to harmful UV rays.
Men Over 50 Have A Higher Risk Of Developing Melanoma
The AAD encourages everyone to take steps to prevent skin cancer and detect it early, when its most treatable. This is especially important for men over 50 as they have an increased risk of developing melanoma compared to the general population.
If you notice any suspicious spots on your skin or your partners skin, or anything that is changing, itching or bleeding, see a board-certified dermatologist.

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.
How To Check Your Skin For Skin Cancer
Skin cancers found and removed early are almost always curable. Finding them early can also prevent disfigurement and in more serious cases can be lifesaving. Skcin recommend you check your skin thoroughly once a month, although if you have previously suffered with skin cancer you may well be required to check more frequently.Should you notice anything suspicious, or feel worried or concerned about any potential abnormality, you should consult your GP or dermatologist as soon as possible.If you are checking your skin for the first time:If you are checking your skin for the first time it is important to do a bit of swatting up on the various types of skin cancers and what to look out for – looking for something new to appear is all well andgood, providing you haven’t missed something that is already there.See Types of skin cancer or how to spot skin cancer for information on the various types of skin cancers and pre-cancerous skin lesions.

Five Easy Steps To Prepare Yourself
As part of a complete early detection strategy, we recommend that you see a dermatologist once a year, or more often if you are at a higher risk of skin cancer, for a full-body, professional skin exam.
To help you prepare and make the most of your appointment, follow these five simple steps.
During the exam
Remember that early detection of skin cancer is the key to the most minimal and cost-effective treatment with the highest chance of a cure. Make your appointment soon!
Look Out For An Ugly Duckling
The Ugly Duckling is another warning sign of melanoma. This recognition strategy is based on the concept that most normal moles on your body resemble one another, while melanomas stand out like ugly ducklings in comparison. This highlights the importance of not just checking for irregularities, but also comparing any suspicious spot to surrounding moles to determine whether it looks different from its neighbors. These ugly duckling lesions or outlier lesions can be larger, smaller, lighter or darker, compared to surrounding moles. Also, isolated lesions without any surrounding moles for comparison are considered ugly ducklings.

How Do You Check Yourself For Skin Cancer
- Stand fully unclothed in front of a full length mirror in a well lit room.
- Start from the scalp and work your way down your entire body.
- Check your scalp by using a brush or hairdryer to part your hair into sections.
- Move to your face and neck, not forgetting around your mouth, around your eyes, ears, nostrils and lips.
- Be sure to check both the top and underneath of your arms including your forearms, wrists, fingers and under nails..
- Move to your torso and back. Use a mirror or get a family member to check your back.
- As you move down your body check your private parts, buttocks, the back of your legs and lower back. Melanoma can be found in places that do not have exposed skin.
- Sit down to inspect each of your legs thoroughly. Prop them on a chair or stool checking both sides of your legs, thighs, shin, ankles as well as the soles of your feet, between your toes and toe nails.
- The best way to monitor changes on your skin is by taking photographs every few months and comparing them to identify any changes. Contact a skin cancer clinic immediately to get a full body screening if you notice growing or discoloured spots when comparing to previous photographs.
Tests For Melanoma Skin Cancer
Most melanomas are brought to a doctors attention because of signs or symptoms a person is having.
If you have an abnormal area on your skin that might be cancer, your doctor will examine it and might do tests to find out if it is melanoma, another type of skin cancer, or some other skin condition. If melanoma is found, other tests may be done to find out if it has spread to other areas of the body.
