How To Diagnose Skin Cancer
First, a doctor will examine a personâs skin and take their medical history. They will usually ask the person when the mark first appeared, if its appearance has changed, if it is ever painful or itchy, and if it bleeds.
The doctor will also ask about the personâs family history and any other risk factors, such as lifetime sun exposure.
They may also check the rest of the body for other atypical moles and spots. Finally, they may feel the lymph nodes to determine whether or not they are enlarged.
The doctor may then refer a person to a skin doctor, or dermatologist. They may examine the mark with a dermatoscope, which is a handheld magnifying device, and take a small sample of skin, or a biopsy, and send it to a laboratory to check for signs of cancer.
Basal Cell Skin Cancer
Basal cell cancer can occur anywhere on the body, but it typically develops on areas regularly exposed to the sun. This type of cancer may appear on your face, neck, or other body parts in the form of:
Flat patches of spots, or lesions, which may be red, purple, or brown in color
Slightly raised, brown or reddish lesions
Fully raised, bumpy lesions with a red or brown color
If you think you may be experiencing any of the symptoms of different skin cancers described above, you should call a doctor to discuss your symptoms. You may find that you simply have a large, non-cancerous mole, and can have your concerns put to rest by a professional. On the other hand, your doctor may be able to diagnose your condition and recommend treatment sooner rather than later. Either way, it is best to be on the side of caution and speak with your doctor about what youve noticed.
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.

What Does Early Signs Of Melanoma Look Like
What Does Melanoma Look Like?
- Asymmetry: The shape of one half does not match the other half.
- Border that is irregular: The edges are often ragged, notched, or blurred in outline.
- Color that is uneven: Shades of black, brown, and tan may be present.
- Diameter: There is a change in size, usually an increase.
What Does Skin Cancer Look Like On Your Face
As you examine your skin for early signs of skin cancer on your face, you should be checking your whole head, as well as your neck. These are the most common locations for skin cancer cases because they get the most sun exposure year-round. If you find a new or changing spot on your skin, use the ABCDE method to look for:
- Asymmetry: If you drew a line through the middle of the spot, would the two halves match up?
- Border: Are the edges of the spot irregular? Look for a scalloped, blurred, or notched edge.
- Color: A healthy blemish or mole should be uniform in color. Varying shades of brown, red, white, blue, black, tan, or pink are cause for concern.
- Diameter: Is the spot larger than 6mm? Skin cancer spots tend to be larger in diameter than a pencil eraser, although they can be smaller.
- Evolving: If the size, shape, or color of a spot changes or it starts to bleed or scab, there is potential for it to be cancerous.

Tips For Screening Moles For Cancer
Examine your skin on a regular basis. A common location for melanoma in men is on the back, and in women, the lower leg. But check your entire body for moles or suspicious spots once a month. Start at your head and work your way down. Check the “hidden” areas: between fingers and toes, the groin, soles of the feet, the backs of the knees. Check your scalp and neck for moles. Use a handheld mirror or ask a family member to help you look at these areas. Be especially suspicious of a new mole. Take a photo of moles and date it to help you monitor them for change. Pay special attention to moles if you’re a teen, pregnant, or going through menopause, times when your hormones may be surging.
Basic Information About Skin Cancer
Cancer is a disease in which cells in the body grow out of control. When cancer starts in the skin, it is called skin cancer.
Skin cancer is the most common cancer in the United States. Some people are at higher risk of skin cancer than others, but anyone can get it. The most preventable cause of skin cancer is overexposure to ultraviolet light, either from the sun or from artificial sources like tanning beds.
Most skin cancers are caused by too much exposure to ultraviolet rays. To lower your risk of getting skin cancer, you can protect your skin from UV rays from the sun and from artificial sources like tanning beds and sunlamps.While enjoying the benefits of being outdoors, people can decrease skin cancer risk by using sun protection. Protect yourself by staying in the shade, wearing protective clothing, and applying and re-applying a broad spectrum sunscreen with a sun protection factor of 15 or higher.Links with this icon indicate that you are leaving the CDC website.

Curettage Electrodesiccation And Cryotherapy
Some dermatologists perform curettage, electrodesiccation, and cryotherapy to treat skin cancer. These are considered to be destructive techniques that are best suited for small, superficial carcinomas with definite borders. During the procedure, layers of skin cells are scraped away using a curette. Any remaining cancer cells are destroyed with the use of an electric needle.
In some cases, liquid nitrogen or cryotherapy is used to freeze the margins of the treatment area. Extremely low temperatures kill the malignant skin cells and create a wound, which will heal in a few weeks. The treatment may leave scars that are flat and round, similar to the size of the skin cancer lesion.
Squamous Cell Carcinoma Early Stages
The second most common form of cancer in the skin is squamous cell carcinoma. At first, cancer cells appear as flat patches in the skin, often with a rough, scaly, reddish, or brown surface. These abnormal cells slowly grow in sun-exposed areas. Without proper treatment, squamous cell carcinoma can become life-threatening once it has spread and damaged healthy tissue and organs.

What Are Possible Complications Of Skin Cancer In A Child
Possible complications depend on the type and stage of skin cancer. Melanoma is more likely to cause complications. And the more advanced the cancer, the more likely there will be complications.
Complications may result from treatment, such as:
Loss of large areas of skin and underlying tissue
Problems with the area healing
Infection in the area
Return of the skin cancer after treatment
Melanoma may spread to organs throughout the body and cause death.
When Is A Mole A Problem
A mole is a benign growth of melanocytes, cells that gives skin its color. Although very few moles become cancer, abnormal or atypical moles can develop into melanoma over time. “Normal” moles can appear flat or raised or may begin flat and become raised over time. The surface is typically smooth. Moles that may have changed into skin cancer are often irregularly shaped, contain many colors, and are larger than the size of a pencil eraser. Most moles develop in youth or young adulthood. It’s unusual to acquire a mole in the adult years.

Less Common Skin Cancers
Uncommon types of skin cancer include Kaposi’s sarcoma, mainly seen in people with weakened immune systems sebaceous gland carcinoma, an aggressive cancer originating in the oil glands in the skin and Merkel cell carcinoma, which is usually found on sun-exposed areas on the head, neck, arms, and legs but often spreads to other parts of the body.

Causes And Risk Factors
Researchers do not know why certain cells become cancerous. However, they have identified some risk factors for skin cancer.
The most important risk factor for melanoma is exposure to UV rays. These damage the skin cellsâ DNA, which controls how the cells grow, divide, and stay alive.
Most UV rays come from sunlight, but they also come from tanning beds.
Some other risk factors for skin cancer include:
- A lot of moles: A person with more than 100 moles is more likely to develop melanoma.
- Fair skin, light hair, and freckles: The risk of developing melanoma is higher among people with fair skin. Those who burn easily have an increased risk.
- Family history:Around 10% of people with the condition have a family history of it.
- Personal history: Melanoma is likelier to form in a person who has already had it. People who have had basal cell or squamous cell cancers also have an increased risk of developing melanoma.
The best way to reduce the risk of skin cancer is to limit oneâs exposure to UV rays. A person can do this by using sunscreen, seeking shade, and covering up when outdoors.
People should also avoid tanning beds and sunlamps to reduce their risk of skin cancer.
It can be easy to mistake benign growths for skin cancer.
The following skin conditions have similar symptoms to skin cancer:
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.

Screening For Skin Cancer
Again, the best way to screen for skin cancer is knowing your own skin. If you are familiar with the freckles, moles, and other blemishes on your body, you are more likely to notice quickly if something seems unusual.
To help spot potentially dangerous abnormalities, doctors recommend doing regular self-exams of your skin at home. Ideally, these self-exams should happen once a month, and should involve an examination of all parts of your body. Use a hand-held mirror and ask friends or family for help so as to check your back, scalp, and other hard-to-see areas of skin. If you or someone else notices a change on your skin, set up a doctors appointment to get a professional opinion.
What Do The Early Stages Of Skin Cancer Look Like
Did you find a mole that looks a little suspicious? Are you questioning if it is skin cancer? For starters, let us just say kudos on paying attention! It is so vital to watch yourself for these things because early detection truly saves lives.
What do the early stages of skin cancer look like?
Skin cancer is an abnormal growth of skin cells. Skin cancer can be found anywhere on your body but is most commonly located on the head, neck, arms, and legs. Dont just think of the obvious places that YOU can see though, think about the places you might not see very well on your own, like your ear or the back of your knee. In the early stages of skin cancer, it can look like what would appear as a brand new mole or freckle or it can develop within an existing mole that you have had for years and years. The key to spotting skin cancer early is by paying attention to your skin. When you notice a new spot, does it appear different? Is the color different than your other moles or freckles? If you even have an inkling of a spot not looking quite right, call yourlocal board-certified dermatologist for an appointment as soon as possible. Skin cancer screenings take around 10 minutes and can be lifesaving.
What to look for in a normal vs abnormal spot
As a dermatologist, when we educate our patients on examining their own skin, we commonly refer them to the ABCDEs.

Looking For Signs Of Skin Cancer
Non melanoma skin cancers tend to develop most often on skin that’s exposed to the sun.
To spot skin cancers early it helps to know how your skin normally looks. That way, you’ll notice any changes more easily.
To look at areas you cant see easily, you could try using a hand held mirror and reflect your skin onto another mirror. Or you could get your partner or a friend to look. This is very important if you’re regularly outside in the sun for work or leisure.
You can take a photo of anything that doesn’t look quite right. If you can it’s a good idea to put a ruler or tape measure next to the abnormal area when you take the photo. This gives you a more accurate idea about its size and can help you tell if it’s changing. You can then show these pictures to your doctor.
Determining If The Cancer Has Spread
As part of your diagnosis, your doctor will also determine what stage the cancer is in. The different stages refer to whether and how far the cancer has spread in your body, on a Roman numeral scale of I to IV. A stage I cancer is small and contained to the body part where it originated, whereas a stage IV cancer has spread aggressively to other parts of the body.
Depending on the type of skin cancer that a person has, it may be more or less likely that it has spread through the body. For instance, basal cell skin cancer rarely spreads beyond the skin where it starts. However, melanomas and large squamous cell carcinomas are more likely to spread into other regions of the body. Cases of melanoma, in particular, may call for further tests to determine the specific stage theyre in.
Your doctor may evaluate multiple factors in order to stage the cancer. Using biopsies and imaging tests, your doctor may take a look at:
The size and thickness of the tumor, and whether it has grown into surrounding tissues
Nearby lymph nodes, to check for signs of cancer spread

Types Of Skin Cancer And What They Look Like
There are many kinds of skin cancer, and they all look a little different. In general, come in and see Dr. Topham when you notice any changes to your skin, which means you need to inspect it regularly.
Moles are common and usually not dangerous, but some can be cancerous. The key is change. If any of your moles change in color, size, height, or shape, its time to get them checked.
Other types of skin cancer show up as a textural issue, a lesion, or a sore. Here are the most common cancers of the skin and their telltale characteristics.
Preparing For Your Appointment
If you have any concerns about the health of your skin, it is important to share them with your doctor. After making an appointment, there are steps you can take to prepare yourself and make the most of your time with your doctor.
Here are some things to consider and be prepared to discuss before visiting the clinic or hospital:
What symptoms are you experiencing ?
When did you first notice your symptoms?
Have there been any major changes or stressors in your life recently?
What medications and/or vitamins are you taking?
What questions do you have for your doctor?
