How Do People Find Signs Of Melanoma On Their Own Skin
Performing a skin self-exam as often as recommended by your dermatologist is the best way. While examining your skin, you want to look for the following:
Mole that is changing in any way
Spot that looks different from the rest of the spots on your skin
Growth or spot on your skin that itches, bleeds, or is painful
Band of color beneath or around a nail
Sore that doesnt heal or heals and returns
The ABCDEs of melanoma can help you find changes to a mole, freckle, or other spot on your skin.

The Four Major Types Of Melanoma
Melanoma can be divided into different subtypes. A few of the most common subtypes are:
- Superficial spreading melanoma.Superficial spreading melanoma is the most common type of melanoma. Lesions are usually flat, irregular in shape, and contain varying shades of black and brown. It can occur at any age.
- Lentigo maligna melanoma. Lentigo maligna melanoma usually affects adults over 65 and involves large, flat, brownish lesions.
- Nodular melanoma.Nodular melanoma can be dark blue, black, or reddish-blue, but may have no color at all. It usually starts as a raised patch.
- Acral lentiginous melanoma.Acral lentiginous melanoma is the least common type. Typically it affects the palms, soles of the feet, or under finger and toenails.
Quick Answer: What Does Oral Melanoma Look Like
This melanoma appears in the oral cavity as a white, mucosa-colored, or red mass.
Because oral malignant melanomas are often clinically silent, they can be confused with a number of asymptomatic, benign, pigmented lesions.
Oral melanomas are largely macular, but nodular and even pedunculated lesions occur.

Squamous Cell Carcinoma In Situ
This photo contains content that some people may find graphic or disturbing.
Squamous cell carcinoma in situ, also known as Bowens disease, is a precancerous condition that appears as a red or brownish patch or plaque on the skin that grows slowly over time. The patches are often found on the legs and lower parts of the body, as well as the head and neck. In rare cases, it has been found on the hands and feet, in the genital area, and in the area around the anus.
Bowens disease is uncommon: only 15 out of every 100,000 people will develop this condition every year. The condition typically affects the Caucasian population, but women are more likely to develop Bowens disease than men. The majority of cases are in adults over 60. As with other skin cancers, Bowens disease can develop after long-term exposure to the sun. It can also develop following radiotherapy treatment. Other causes include immune suppression, skin injury, inflammatory skin conditions, and a human papillomavirus infection.
Bowens disease is generally treatable and doesnt develop into squamous cell carcinoma. Up to 16% of cases develop into cancer.
What Will It Look Like
There are a number of signs that we are warned to look out for when checking our moles. The ABDCE method include the following:
- Asymmetry: Any mole where one side is not the same as the other. In other words it is not round.
- Borders: Any edge that is irregular is worth getting checked. If they are blurred, notched or ragged it could be a bad sign.
- Colour: Moles should be even in colour and just one colour across the entire mole. If you have a mix of colours or any areas that are grey, pink or blue, it makes sense to have them checked.
- Diameter: Normal moles are rarely any more than 5mm in size anything larger should be checked. However, some may be very small.
- Evolving: Any mole that has changed in size, colour or if it has started to itch over the last few weeks should be checked.
Dont forget that you dont need all of these signs just one will do.

When To See A Dermatologist
Plan an appointment with a dermatologist as soon as possible if you notice any changes to your skin that worry you. Not all skin changes are evidence of cancer. Your dermatologist will evaluate your skin changes to identify the cause and prepare a plan of treatment. Remember, early detection of skin cancer is the key to proper treatment and survival. Almost all skin cancers respond favorably to treatment when detected early enough.
Basal Cell And Squamous Cell Carcinomasigns And Symptoms
The most common warning sign of skin cancer is a change on the skin, especially a new growth or a sore that doesn’t heal. The cancer may start as a small, smooth, shiny, pale or waxy lump. It also may appear as a firm red lump. Sometimes, the lump bleeds or develops a crust.
Both basal and squamous cell cancers are found mainly on areas of the skin that are exposed to the sun the head, face, neck, hands and arms. But skin cancer can occur anywhere.
An early warning sign of skin cancer is the development of an actinic keratosis, a precancerous skin lesion caused by chronic sun exposure. These lesions are typically pink or red in color and rough or scaly to the touch. They occur on sun-exposed areas of the skin such as the face, scalp, ears, backs of hands or forearms.
Actinic keratoses may start as small, red, flat spots but grow larger and become scaly or thick, if untreated. Sometimes they’re easier to feel than to see. There may be multiple lesions next to each other.
Early treatment of actinic keratoses may prevent them from developing into cancer. These precancerous lesions affect more than 10 million Americans. People with one actinic keratosis usually develop more. Up to 1 percent of these lesions can develop into a squamous cell cancer.
Basal cell carcinoma is the most commonly diagnosed skin cancer. In recent years, there has been an upturn in the diagnoses among young women and the rise is blamed on sunbathing and tanning salons.

Risk Of Further Melanomas
Most people treated for early melanoma do not have further trouble with the disease. However, when there is a chance that the melanoma may have spread to other parts of your body, you will need regular check-ups.
Your doctor will decide how often you will need check-ups everyone is different. They will become less frequent if you have no further problems.
After treatment for melanoma it is important to limit exposure to the sun’s UV radiation. A combination of sun protection measures should be used during sun protection times .
As biological family members usually share similar traits, your family members may also have an increased risk of developing melanoma and other skin cancers. They can reduce their risk by spending less time in the sun and using a combination of sun protection measures during sun protection times.
It is important to monitor your skin regularly and if you notice any changes in your skin, or enlarged lymph glands near to where you had the cancer, see your specialist as soon as possible.
Where Are They Found
A few of the common locations or growth sites where one can find nodular melanoma are the head, trunk, and neck of the body. Not the same case as the other types of skin cancer, nodular melanoma is known to start or grow as new developments instead of developing or growing within a pre-existing mole. It would take a period of as little as three months time for these types of cancer to start spreading internally in the body. Nodular melanoma is very dangerous since it can quickly jump to the advanced stage of skin cancer. For this reason, it has been termed a deadly form of skin cancer. If the nodular melanoma reaches the advanced stage, it would become difficult to get it treated successfully.

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.
What Should I Do About Atypical Moles
Protecting yourself from harmful ultraviolet radiation emitted by the sun is especially important for people that already have a high number of common moles or atypical moles. Always wear sunscreen or protective clothing.
Doctors recommend that people with atypical moles perform a self-check on their skin once a month. During these routine checks, look for the following in atypical moles:
- Changes in color, such as when a mole becomes darker or develops new colors
- Changes is size, such as when a mole grows rapidly or becomes larger than the tip of a pencil eraser
- Changes in texture, such as becoming hard or the development of a scaly, rough, pebbly, or dry surface
- Changes in shape, particularly when the edges of a mole become irregular, jagged, or undefined
If you notice any changes in color, size, texture, and shape, speak to your doctor right away.

What Are The Symptoms Of Actinic Keratosis
Actinic keratosis develops slowly. It most likely appears on areas of skin often exposed to the sun. These can include the face, ears, bald scalp, neck, backs of hands and forearms, and lips. It tends to lie flat against the skin of the head and neck, but appears as a bump on arms and hands. The base of an actinic keratosis may be light or dark, tan, pink, red, or a combination of these. Or it may be the same color as the skin. The scale or crust may be horny, dry, and rough. In some cases, it may itch or have a prickly or sore feeling.
Often, a person will have more than one actinic keratosis lesion. Actinic keratoses that develop on the lip are called actinic cheilitis.
Afx Or Atypical Fibroxanthoma
An uncommon tumor that is typically found on the ears, scalp or other areas of the skin that is exposed to the sun, AFX usually occurs on elderly patients. It has the potential to behave aggressively and metastasize. Its treatment options include Mohs micrographic surgery, wide local excision and C & D or curettage and desiccation. Once the tumor is removed, a follow-up checkup is required to monitor recurrence or signs of metastases.
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.
A is for Asymmetry
D is for Diameter or Dark
E is for Evolving
E is for Evolving
When Should I Call My Doctor
You should have a skin examination by a doctor if you have any of the following:
- A personal history of skin cancer or atypical moles .
- A family history of skin cancer.
- A history of intense sun exposure as a young person and painful or blistering sunburns.
- New or numerous large moles.
- A mole that changes in size, color or shape.
- Any mole that itches, bleeds or is tender.
A note from Cleveland Clinic
Receiving a diagnosis of melanoma can be scary. Watch your skin and moles for any changes and seeing your doctor regularly for skin examinations, especially if youre fair-skinned, will give you the best chances for catching melanoma early when its most treatable.

How Is Metastasis Detected
If your healthcare provider suspects that your melanoma may have spread, there are several tools available to verify the diagnosis. These include a blood test for lactate dehydrogenase , which increases when melanoma metastasizes, and imaging studies, such as chest X-ray, computed tomography , magnetic resonance imaging , positron emission tomography and ultrasound.
The practitioner may also need to take a sample of your lymph nodes, using a procedure called âsentinel lymph node mapping.â If confirmed, there are many treatments available, including chemotherapy, immunotherapy, radiation therapy and surgery.
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.

Dont Mistake Skin Cancer For A Harmless Issue
The importance of the prompt treatment of skin cancer cannot be overstated. Unfortunately, some individuals may mistake skin cancer for other skin problems like a sunspot, pimple, scar, or dry skin. If you are questioning the health of a blemish or mole, you should schedule a skin cancer screening with a dermatologist without delay.
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.
A Dermatologist Should Examine All Actinic Keratosis
If you find anything on your skin that looks like an AK, you should see a dermatologist. AKs are precancerous growths, and some turn into a type of skin cancer called squamous cell carcinoma. Being under a dermatologists care can help you get the treatment you need.

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.
