Many People Ask: What Does Skin Cancer Look Like The Answer To The Question Is Pretty Simple When You Learn The Abcde Rules
When you have a mysterious spot on your skin, you may find yourself becoming a bit concerned. Spots that randomly show up and dont look right may possibly be skin cancer, but not always.
Skin cancer is an overgrowth of skin cells that do not stop reproducing and can grow into the bodys other tissues, lymph nodes, organs and bone. This type of cancer is one of the more common cancers in the U.S. The risk factors for developing skin cancer are:
- Excessive exposure to sunlight without sunscreen
- People with transplanted organs
- Family history of cancer or skin cancer
- Fair skinned people
- People who are over 40
What Tests Are Used To Stage Melanoma
There are several tests your doctor can use to stage your melanoma. Your doctor may use these tests:
- Sentinel Lymph Node Biopsy: Patients with melanomas deeper than 0.8 mm, those who have ulceration under the microscope in tumors of any size or other less common concerning features under the microscope, may need a biopsy of sentinel lymph nodes to determine if the melanoma has spread. Patients diagnosed via a sentinel lymph node biopsy have higher survival rates than those diagnosed with melanoma in lymph nodes via physical exam.
- Computed Tomography scan: A CT scan can show if melanoma is in your internal organs.
- Magnetic Resonance Imaging scan: An MRI scan is used to check for melanoma tumors in the brain or spinal cord.
- Positron Emission Tomography scan: A PET scan can check for melanoma in lymph nodes and other parts of your body distant from the original melanoma skin spot.
- Blood work: Blood tests may be used to measure lactate dehydrogenase before treatment. Other tests include blood chemistry levels and blood cell counts.
How Are Moles Evaluated
If you find a mole or spot that has any ABCDE’s of melanoma — or one that’s tender, itching, oozing, scaly, doesn’t heal or has redness or swelling beyond the mole — see a doctor. Your doctor may want to remove a tissue sample from the mole and biopsy it. If found to be cancerous, the entire mole and a rim of normal skin around it will be removed and the wound stitched closed. Additional treatment may be needed.

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.
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.
A Sore That Doesn’t Heal
Many skin cancers are first dismissed as being due to a bug bite, minor injury, or irritation, but become more obvious when they don’t go away over time. If you notice a sore on your skin that refuses to heal, even if it seems to be healing but then reappears, talk to your healthcare provider. In general, any skin change that hasn’t resolved on its own over a period of two weeks should be evaluated.

What Is A Common Mole
A common mole is a growth on the skin that develops when pigment cells grow in clusters. Most adults have between 10 and 40 common moles. These growths are usually found above the waist on areas exposed to the sun. They are seldom found on the scalp, breast, or buttocks.
Although common moles may be present at birth, they usually appear later in childhood. Most people continue to develop new moles until about age 40. In older people, common moles tend to fade away.
Another name for a mole is a nevus. The plural is nevi.
What Are The Differences Between A Common Mole A Dysplastic Nevus And A Melanoma
Common moles, dysplastic nevi, and melanoma vary by size, color, shape, and surface texture. The list below summarizes some differences between moles and cancer. Another important difference is that a common mole or dysplastic nevus will not return after it is removed by a full excisional biopsy from the skin, but melanoma sometimes grows back. Also, melanoma can spread to other parts of the body.

When To See A Doctor
Many melanomas are dark brown or black and are often described as changing, different, unusual, or ugly looking. However, any skin abnormality that is growing or changing quickly and does not go away, whether colored or not, should be examined by a doctor. Bleeding may be a sign of more advanced melanoma. In addition, the appearance of a new and unusual mole is more likely to be melanoma.
If you are concerned about a new or existing mole, please talk with your family doctor or a dermatologist. Your doctor will ask how long and how often youve been experiencing the symptom, in addition to other questions. This is to help figure out the cause of the problem, called a diagnosis.
The next section in this guide is Diagnosis. It explains what tests may be needed to learn more about the cause of the symptoms. Use the menu to choose a different section to read in this guide.
Melanomas That Could Be Mistaken For A Common Skin Problem
Melanoma that looks like a bruise
Melanoma can develop anywhere on the skin, including the bottom of the foot, where it can look like a bruise as shown here.
Melanoma that looks like a cyst
This reddish nodule looks a lot like a cyst, but testing proved that it was a melanoma.
In people of African descent, melanoma tends to develop on the palm, bottom of the foot, or under or around a nail.
Did you spot the asymmetry, uneven border, varied color, and diameter larger than that of a pencil eraser?
Dark line beneath a nail
Melanoma can develop under a fingernail or toenail, looking like a brown line as shown here.
While this line is thin, some are much thicker. The lines can also be much darker.

Recommendations For Prevention And Early Detection Of Skin Cancer In People Of Color
Prevention is better than cure and more than 90% of skin cancers are preventable . Because many people of color believe that they are not at risk of skin cancer, education through media and doctors offices is extremely important. People of color should perform regular self examination of their skin from head to the toe carefully every month. There are various types of skin tumors, many are benign which include moles , warts and lipomas etc that can develop from different types of skin cells . However, unusual moles, sores, lumps, blemishes, markings or changes in the way an area of the skin looks or feels may be a sign of melanoma or another type of skin cancer or a warning that it might occur. Know your ABCDEs can be a good guide for people of color to detect melanoma at an early stage .

What Is Skin Cancer
Skin cancer is the most common form of cancer in the United States. Almost all skin cancers are the result of too much exposure to ultraviolet light. This is found in sunlight, tanning booths, and sunlamps. Skin cancer is usually one of the most curable types of cancer.
Basal cell carcinoma and squamous cell carcinoma are two of the most common forms of skin cancer. They are very curable. These cancers occur in the basal and squamous cell layers at the top of the skin. They are almost always slow-growing. If found early, they are easy to treat and do not spread.
Melanoma is a less common but aggressive form of skin cancer. It occurs in skin cells that make a skin color pigment called melanin. If it is not found early, it will likely spread to other tissues. It can spread through the whole body and may cause death. Only 2% of skin cancer cases are melanoma. But it causes the most deaths from skin cancer.
Can A Dysplastic Nevus Turn Into Melanoma
Yes, but most dysplastic nevi do not turn into melanoma . Most remain stable over time. Researchers estimate that the chance of melanoma is about ten times greater for someone with more than five dysplastic nevi than for someone who has none, and the more dysplastic nevi a person has, the greater the chance of developing melanoma .

What Are The Signs Of Melanoma
Knowing how to spot melanoma is important because early melanomas are highly treatable. Melanoma can appear as moles, scaly patches, open sores or raised bumps.
Use the American Academy of Dermatology’s “ABCDE” memory device to learn the warning signs that a spot on your skin may be melanoma:
- Asymmetry: One half does not match the other half.
- Border: The edges are not smooth.
- Color: The color is mottled and uneven, with shades of brown, black, gray, red or white.
- Diameter: The spot is greater than the tip of a pencil eraser .
- Evolving: The spot is new or changing in size, shape or color.
Some melanomas don’t fit the ABCDE rule, so tell your doctor about any sores that won’t go away, unusual bumps or rashes or changes in your skin or in any existing moles.
Another tool to recognize melanoma is the ugly duckling sign. If one of your moles looks different from the others, its the ugly duckling and should be seen by a dermatologist.
Identifying Basal Cell Carcinomas And Squamous Cell Carcinomas
Before they become large, obvious cancers, “Basal cell carcinomas tend to be small, pink macules or papules small, flat areas or minimally bumpy areas on the skin that can at times look bright pink or occasionally are pearly white,” Dr. Paragh says.
One other sign of basal cell carcinomas is that they may frequently break open and can bleed or, at times, can be covered by a scab. Seemingly out of nowhere, a tiny open sore or wound may appear. The lesions may even look as if they healed at times, but the same spot will reopen and become a sore again.
“For basal cell carcinomas, people should look for small recurrent sores, areas that break open easily, areas that bleed easily, and pearly or pink bumps on the skin that continue to grow very slowly. Occasionally basal cell carcinomas may also show up as a small scar-like change on the skin in an area with no prior trauma, Dr. Paragh says. “As opposed to normal scars, these scar-like basal cell carcinomas will spontaneously grow, but very slowly.” Later “larger ulcerations with rolled borders, can also appear and show up as a more ominous sign of basal cell skin cancers.”

Where Does Bcc Develop
As the above pictures show, this skin cancer tends to develop on skin that has had lots of sun exposure, such as the face or ears. Its also common on the bald scalp and hands. Other common areas for BCC include, the shoulders, back, arms, and legs.
While rare, BCC can also form on parts of the body that get little or no sun exposure, such as the genitals.

Basal cell carcinoma and squamous cell carcinoma
These are the most common forms of skin cancer, and are collectively referred to as non-melanoma skin cancers.
These arise within the top layer of the skin and can appear on any sun-exposed area of the body, but are most frequently found on the face, ears, bald scalp, and neck.
Basal cell carcinoma frequently appears as a pearly bump, whereas squamous cell carcinoma often looks like a rough, red, scaly area, or an ulcerated bump that bleeds.
Although non-melanoma skin cancer spreads slowly, if left untreated, it can lead to disfigurement.
Researchers estimate that 5.4 million cases of non-melanoma skin cancer, including basal cell carcinoma and squamous cell carcinoma, were diagnosed in 3.3 million people in the United States in 2012.
See a board-certified dermatologist if you spot anything changing, itching, or bleeding on your skin.
When caught early and treated properly, skin cancer is highly curable.
To help you spot skin cancer early, when its most treatable, the American Academy of Dermatology recommends that everyone learn the ABCDEs of melanoma:

Actinic Keratosis Signs And Symptoms
Many people have actinic keratosis , also called solar keratosis, on their skin. It shows that youâve had enough sun to develop skin cancer, and it is considered a precursor of cancer, or a precancerous condition.
Usually AK shows up on the parts of your body that have received the most lifetime sun exposure, like the face, ears, scalp, neck, backs of the hands, forearms, shoulders and lips.
Some of the same treatments used for nonmelanoma skin cancers are used for AK to ensure it does not develop into a cancerous lesion.
This abnormality develops slowly. The lesions are usually small, about an eighth of an inch to a quarter of an inch in size. You may see a few at a time. They can disappear and later return.
- AK is a scaly or crusty bump on the skinâs surface and is usually dry and rough. It can be flat. An actinic keratosis is often noticed more by touch than sight.
- It may be the same color as your skin, or it may be light, dark, tan, pink, red or a combination of colors.
- It can itch or produce a prickling or tender sensation.
- These skin abnormalities can become inflamed and be encircled with redness. Rarely, they bleed.

Dark Stipe Under Nail
Skin cancer doesn’t just show up in obvious placesit can also be more hidden. Although rare, acral-lentiginous melanoma can show up as a narrow, dark streak under your nail, whether that’s your fingers or toes. According to the Mayo Clinic, it’s something that happens more commonly in African Americans or anyone with darker skin, but it’s something for everyone to be aware of.
A Primer On Skin Cancer
Malignant melanoma, especially in the later stages, is serious and treatment is difficult. Early diagnosis and treatment can increase the survival rate. Nonmelanoma skin cancers include basal cell carcinoma and squamous cell carcinoma. Both are common and are almost always cured when found early and treated. People who’ve had skin cancer once are at risk for getting it again they should get a checkup at least once a year.

Get To Know Your Skin
It is also a good idea to talk to your doctor about your level of risk and for advice on early detection.
It’s important to get to know your skin and what is normal for you, so that you notice any changes. Skin cancers rarely hurt and are much more frequently seen than felt.
Develop a regular habit of checking your skin for new spots and changes to existing freckles or moles.
Flat Red Patches And Rashes
One type of cancer that affects the skin, T-cell lymphoma, often begins with very itchy, flat, red patches and plaques that are easily mistaken for eczema or psoriasis.
One type of T-cell lymphoma, mycosis fungoids, transitions from these patches to dome-shaped nodules, and then to extensive reddened areas on multiple areas of the body. It may spread to lymph nodes and other regions of the body such as the lungs, liver, and bones. T-cell lymphomas most often begin on the buttocks, groin, hips, armpits, and chest.
Other cancers, such as breast cancer, may spread to the skin and initially be mistaken for a benign rash. Inflammatory breast cancer is a type of breast cancer that originates in the skin and appears, at first, to be an eczematous type of rash.
