Am I At Risk Of Skin Cancer
Everyone is at some risk of developing skin cancer. Your risk increases as you grow older. Most skin cancers are caused by over-exposure to the suns ultraviolet radiation.
Your risk of skin cancer increases if you:
- have someone in your family who has had skin cancer
- have had bad sunburn before
- have fair skin
- have many moles on your skin
- spend a lot of time outdoors without sun protection or work outdoors
- have used solariums or sun lamps
- have a compromised immune system or are taking immunosuppression medication

You Can Find Skin Cancer On Your Body
The best way to find skin cancer is to examine yourself. When checking, you want to look at the spots on your skin. And you want to check everywhere from your scalp to the spaces between your toes and the bottoms of your feet.
If possible, having a partner can be helpful. Your partner can examine hard-to-see areas like your scalp and back.
Getting in the habit of checking your skin will help you notice changes. Checking monthly can be beneficial. If you have had skin cancer, your dermatologist can tell you how often you should check your skin.
People of all ages get skin cancer
Checking your skin can help you find skin cancer early when its highly treatable.

What Is The Outlook For People With Skin Cancer
Nearly all skin cancers can be cured if they are treated before they have a chance to spread. The earlier skin cancer is found and removed, the better your chance for a full recovery. Ninety percent of those with basal cell skin cancer are cured. It is important to continue following up with a dermatologist to make sure cancer does not return. If something seems wrong, call your doctor right away.
Most skin cancer deaths are from melanoma. If you are diagnosed with melanoma:
- The five-year survival rate if its detected before it spreads to the lymph nodes is 99%.
- The five-year survival rate if it has spread to nearby lymph nodes is 66%.
- The five-year survival rate if it has spread to distant lymph nodes and other organs is 27%.
What Happens During A Skin Check
This appointment allows your dermatologist to examine your skin â all of your skin â for points of concern. âThe expectation should be that every nook and cranny of you is being looked at during that exam, including your scalp, behind your ears, bottom of your feet, in-between your toes, in the genitalia, et cetera,â Dr. Markowitz says.
To do so, once you reach the examination room you will be asked to disrobe and change into a gown. Dr. Henry notes that some doctors may ask you to remove your undergarments, while others will just move them around while checking. âEither way, you shouldn’t be alarmed because it really is important that we look at everything,â Dr. Henry adds. Your doctor may also refer you to your ob-gyn or primary care doctor for the examination of the genital area.
Dr. Henry adds that she checks inside the eyelids, inside the mouth, under the tongue, and in the nose. She also always feels the lymph nodes, which is especially important for someone who has had cancer in the past. Photos may be taken in order to track changes on certain moles the next time you visit the office.
These examinations shouldnât be done with just the naked eye either. According to Dr. Markowitz, your doctor should be utilizing a specialized magnifying tool called a dermatoscope, which allows them to get a closer, clearer image of a mole or area of the body and even catch cancers before they have any clinical features, or the ABCDEs of melanoma.

Skin Cancer Screening And Diagnosis
A skin cancer screening can help identify skin cancer in its earliest stages while its easiest to treat. To detect and diagnose skin cancer, a dermatologist checks the skin over your entire body. He or she also asks questions about your past health and possible skin cancer symptoms you may have noticed, like a skin lesion that burns or itches without improvement.
Your doctor will use a bright light to examine your body for any atypical moles or other changes in your skin. Some doctors may make whats called a mole map to identify potentially cancerous moles and see if their appearance changes from year to year. Your doctor will also ask you questions about when your skin or mole appearance changes started, whether you have any family history of skin cancer and if youve had exposure to certain chemicals or substances.
Is There Anything Else I Need To Know About A Skin Cancer Screening
Exposure to the ultraviolet rays that come from the sun plays a major role in causing skin cancer. You are exposed to these rays anytime you are out in the sun, not just when you are at the beach or pool. But you can limit your sun exposure and help reduce your risk of skin cancer if you take a few simple precautions when out in the sun. These include:
- Using a sunscreen with a sun protection factor of at least 30
- Seeking shade when possible
- Wearing a hat and sunglasses
Sunbathing also increases your risk of skin cancer. You should avoid outdoor sunbathing and never use an indoor tanning salon. There is no safe amount of exposure to artificial tanning beds, sunlamps, or other artificial tanning devices.
If you have questions about reducing your risk of skin cancer, talk to your health care provider.

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:
- Immunohistochemistry
- 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 .
What Are The Signs Of Skin Cancer
The most common warning sign of skin cancer is a change on your skin, typically a new growth, or a change in an existing growth or mole. The signs and symptoms of common and less common types of skin cancers are described below.
Basal cell carcinoma
Basal cell cancer is most commonly seen on sun-exposed areas of skin including your hands, face, arms, legs, ears, mouths, and even bald spots on the top of your head. Basal cell cancer is the most common type of skin cancer in the world. In most people, its slow growing, usually doesnt spread to other parts of the body and is not life-threatening.
Signs and symptoms of basal cell carcinoma include:
- A small, smooth, pearly or waxy bump on the face, ears, and neck.
- A flat, pink/red- or brown-colored lesion on the trunk or arms and legs.
- Areas on the skin that look like scars.
- Sores that look crusty, have a depression in the middle or bleed often.
Squamous cell carcinoma
Squamous cell cancer is most commonly seen on sun-exposed areas of skin including your hands, face, arms, legs, ears, mouths, and even bald spots on the top of your head. This skin cancer can also form in areas such as mucus membranes and genitals.
Signs and symptoms of squamous cell carcinoma include:
- A firm pink or red nodule.
- A rough, scaly lesion that might itch, bleed and become crusty.
Melanoma
Signs and symptoms of melanoma include:
- A brown-pigmented patch or bump.
- A mole that changes in color, size or that bleeds.

Medical Tests For Early Detection
A painless medical technique being used for early detection of melanoma is epiluminescence microscopy, or dermoscopy. Using a handheld device, a doctor can evaluate the patterns of size, shape, and pigmentation in pigmented skin lesions. Among trained, experienced medical professionals, dermoscopy may reduce the number of biopsies of pigmented lesions to rule out melanoma, although more research is needed.
Confocal scanning laser microscopy is another new technology that may improve the examination of possible melanoma lesions. Currently, it is only used in research studies, called clinical trials, and is available in a few major medical centers.
The next section in this guide is Symptoms and Signs. It explains what body changes or medical problems melanoma can cause. Use the menu to choose a different section to read in this guide.
Types Of Skin Cancer:
Basal Cell found mainly in areas exposed to the sun, very common and usually very treatable. Detected at an early stage and removed promptly are almost always curable and cause minimal damage.Squamous Cell typically develops in chronic sun-exposed areas of your body.Melanoma more likely to grow and spread than the more common typesMerkel Cell very rare and tends to grow quickly, may be hard to treat if it spreads past beyond the skin

Screening For Skin Cancer May Include Examination By Both The Patient And The Health Care Provider
A visual self-exam by the patient and a clinical examination by the health care provider may be used to screen for skin cancer.
During a skin exam a doctor or nurse checks the skin for moles, birthmarks, or other pigmented areas that look abnormal in color, size, shape, or texture. Skin exams to screen for skin cancer have not been shown to decrease the number of deaths from the disease.
Regular skin checks by a doctor are important for people who have already had skin cancer. If you are checking your skin and find a worrisome change, you should report it to your doctor.
If an area on the skin looks abnormal, a biopsy is usually done. The doctor will remove as much of the suspicious tissue as possible with a localexcision. A pathologist then looks at the tissue under a microscope to check for cancer cells. Because it is sometimes difficult to tell if a skin growth isbenign or malignant , you may want to have the biopsy sample checked by a second pathologist.
Most melanomas in the skin can be seen by the naked eye. Usually, melanoma grows for a long time under the top layer of skin but does not grow into the deeper layer of skin . This allows time for skin cancer to be found early. Melanoma is easier to cure if it is found before it spreads.
Fine Needle Aspiration Biopsy
FNA biopsy is not used on suspicious moles. But it may be used, for example, to biopsy large lymph nodes near a melanoma to find out if the melanoma has spread to them.
For this type of biopsy, the doctor uses a syringe with a thin, hollow needle to remove very small pieces of a lymph node or tumor. The needle is smaller than the needle used for a blood test. A local anesthetic is sometimes used to numb the area first. This test rarely causes much discomfort and does not leave a scar.
If the lymph node is just under the skin, the doctor can often feel it well enough to guide the needle into it. For a suspicious lymph node deeper in the body or a tumor in an organ such as the lung or liver, an imaging test such as ultrasound or a CT scan is often used to help guide the needle into place.
FNA biopsies are not as invasive as some other types of biopsies, but they may not always collect enough of a sample to tell if a suspicious area is melanoma. In these cases, a more invasive type of biopsy may be needed.

How To Do A Skin Self
You dont need x-rays or blood tests to find skin cancer early just your eyes and a mirror. If you have skin cancer, finding it early is the best way to make sure it can be treated successfully.
Although the American Cancer Society does not have guidelines for the early detection of skin cancer, many doctors recommend checking your own skin regularly, typically once a month.
Regular skin self-exams are especially important for people who are at higher risk of skin cancer, such as people with reduced immunity, people who have had skin cancer before, and people with a strong family history of skin cancer. Talk to your doctor about how often you should examine your skin.
A skin self-exam is best done in a well-lit room in front of a full-length mirror. You can use a hand-held mirror to look at areas that are hard to see, such as the backs of your thighs. A spouse, partner, or close friend or family member may be able to help you with these exams, especially for those hard-to-see areas like your back or scalp.
The first time you examine your skin, spend time carefully going over the entire surface. Learn the pattern of moles, blemishes, freckles, and other marks on your skin so that youll notice any changes next time. Be sure to show your doctor any areas that concern you.
Follow these step-by-step instructions to examine your skin:
How Common Is Skin Cancer
Skin cancer is the most common cancer diagnosed in the U.S.
Other skin cancer facts:
- Around 20% of Americans develop skin cancer sometime in their life.
- Approximately 9,500 Americans are diagnosed with skin cancer every day.
- Having five or more sunburns in your life doubles your chance of developing melanoma. The good news is that the five-year survival rate is 99% if caught and treated early.
- Non-Hispanic white persons have almost a 30 times higher rate of skin cancer than non-Hispanic Black or Asian/Pacific Islander persons.
- Skin cancer in people with skin of color is often diagnosed in later stages when its more difficult to treat. Some 25% of melanoma cases in African Americans are diagnosed when cancer has spread to nearby lymph nodes.

What Happens If They Find Something
If your doctor finds a spot that could be cancerous orpre-cancerous, theyll likely want to take a picture for your medical chart andperform a skin biopsy.
During a biopsy, the doctor will remove a small amount of tissueto be examined under a microscope by a pathologist. This is a simple procedurethat can be done right then and there, in the office. Theyll clean the area ofskin where the spot is located, numb it with an injection of anesthesia, anduse a blade or scalpel to take a sample of the skin. You shouldnt feel anypain, aside from the pinch from the injection.
That sample will be sent to the lab for testing, and your doctor willshare the results with you when they are available. This usually happens withina few days but could take up to a week or longer.
If the spot turns out to be cancerous, it may need to becompletely removed or treated with other methods, Dr. Riley says.
What Happens During A Skin Cancer Check
Your doctor will probably ask you some questions to assess your risk of skin cancer. You will usually need to undress for the skin examination. Your doctor may use a special device with a magnifying lens to look at any suspicious spots on your skin.
If your doctor suspects a skin cancer, they may remove it or perform a biopsy . Alternatively, they may refer you to a specialist.
