How To Recognize Melanoma Skin Cancer

Major Signs Of Skin Cancer

To identify signs that could indicate the development of skin cancer exists an exam, called the ABCD, which is made from the observation of the characteristics of stains and pintas, to check if there are signs that can match cancer.

The top 4 characteristics that may indicate that a stain is a sign of skin cancer are:

These characteristics can be observed at home, and help to identify possible skin cancer lesions, but the diagnosis should always be made by a doctor. Thus, when you have some stain, paint or sign with these characteristics it is recommended to mark consultation in the dermatologist.

The best way to identify any alteration in the skin is to observe every body, including the back, behind the ears, head and also the plant of the feet, about 1 a to 2 times a year, facing the mirror. They should be sought out spots, signs or irregular pads, which change in size, shape or color, or by wounds that do not heal more than 1 month.

What Is Melanoma Cancer

Melanoma is a serious type of skin cancer. Most melanoma is treated surgically, and in many cases this surgery is curative. Through numerous clinical trials, the surgery that is required to treat melanoma has become less invasive. A number of these less radical procedures were pioneered at the Saint Johns Cancer Institute Melanoma Program.

100,350people in the U.S. will be diagnosed with melanoma in 2020 and the American Cancer Society estimates that number will continue to increase year after year.

Diagnosis Treatment And Results

How do dermatologists diagnose melanoma?

To diagnose melanoma, a dermatologist begins by looking at a patients skin. A dermatologist will carefully examine moles and other suspicious spots. To get a better look, a dermatologist may use a device called a dermascope.

The device shines a light on the skin. It magnifies the skin. This helps the dermatologist see pigment and structures in the skin.

If the dermatologist finds a mole or other spot that looks like melanoma, the dermatologist will remove it . The removed skin will be sent to lab. Your dermatologist may call this a biopsy. Melanoma cannot be diagnosed without a biopsy.

The biopsy is quick, safe and easy for a dermatologist to perform. This type of biopsy should not cause anxiety. The discomfort and risks are minimal.

If the biopsy report says that the patient has melanoma, the report also may tell the stage of the melanoma. Stage tells the doctor how deeply the cancer has grown in the skin.

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.

Are There Different Kinds Of Skin Cancer

There are many types of skin cancer. Your doctor can tell you more about the type of skin cancer you have.

Basal cell and squamous cell skin cancers are much more common than melanoma and dont often spread to other parts of the body. Melanoma is more deadly because it is more likely to spread to other parts of the body.

Can Changing My Diet Help Prevent Melanoma

The American Cancer Society advocates eating a plant-based diet over an animal-based diet as part of a healthy plan to avoid all cancers. Growing evidence suggests that plants pack a powerful punch in any fight against cancer because they’re nutritious, cholesterol-free and fiber-rich.

Theres no doubt that a healthy diet can protect your immune system. Having a strong immune system is important to help your body fight disease. Some research has shown that a Mediterranean diet is a healthy choice that may help prevent the development of cancer. Talk to your healthcare provider about the role food plays in lowering your cancer risks.

Some skin and immune-system healthy foods to consider include:

• Daily tea drinking: The polyphenols in tea help strengthen your immune system. Green tea contains more polyphenols than black tea.
• High vegetable consumption: Eating carrots, cruciferous and leafy vegetables is linked to the prevention of cutaneous melanoma.
• Weekly fish intake: Study participants who ate fish weekly seemed to avoid developing the disease when compared to those who did not eat fish weekly.

How To Perform A Self

1. Examine your face

Especially your nose, lips, mouth and ears front and back. Use one or both mirrors to get a clear view.

2. Inspect your scalp

Thoroughly inspect your scalp, using a blow-dryer and mirror to expose each section to view. Get a friend or family member to help, if you can.

3. Check your hands

Palms and backs, between the fingers and under the fingernails. Continue up the wrists to examine both the front and back of your forearms.

4. Scan your arms

Standing in front of the full-length mirror, begin at the elbows and scan all sides of your upper arms. Dont forget the underarms.

5. Inspect your torso

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.

Sentinel Lymph Node Biopsy

If melanoma has been diagnosed and has any concerning features , a sentinel lymph node biopsy is often done to see if the cancer has spread to nearby lymph nodes, which in turn might affect treatment options. This test can be used to find the lymph nodes that are likely to be the first place the melanoma would go if it has spread. These lymph nodes are called sentinel nodes .

To find the sentinel lymph node , a doctor injects a small amount of a radioactive substance into the area of the melanoma. After giving the substance time to travel to the lymph node areas near the tumor, a special camera is used to see if it collects in one or more sentinel lymph nodes. Once the radioactive area has been marked, the patient is taken for surgery, and a blue dye is injected in the same place the radioactive substance was injected. A small incision is then made in the marked area, and the lymph nodes are then checked to find which one became radioactive and turned blue. These sentinel nodes are removed and looked at under a microscope.

If there are no melanoma cells in the sentinel nodes, no more lymph node surgery is needed because it is very unlikely the melanoma would have spread beyond this point. If melanoma cells are found in the sentinel node, the remaining lymph nodes in this area are typically removed and looked at as well. This is known as a lymph node dissection .

Who Gets Skin Cancer And Why

Sun exposure is the biggest cause of skin cancer. But it doesn’t explain skin cancers that develop on skin not ordinarily exposed to sunlight. Exposure to environmental hazards, radiation treatment, and even heredity may play a role. Although anyone can get skin cancer, the risk is greatest for people who have:

• Fair skin or light-colored eyes
• An abundance of large and irregularly-shaped moles
• A family history of skin cancer
• A history of excessive sun exposure or blistering sunburns
• Lived at high altitudes or with year-round sunshine
• Received radiation treatments

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 Are The Signs And Symptoms Of Melanoma

Melanoma is a skin cancer that can show up on the skin in many ways. It can look like a:

• Changing mole

• Spot that looks like a new mole, freckle, or age spot, but it looks different from the others on your skin

• Spot that has a jagged border, more than one color, and is growing

• Dome-shaped growth that feels firm and may look like a sore, which may bleed

• Dark-brown or black vertical line beneath a fingernail or toenail

• Band of darker skin around a fingernail or toenail

• Slowly growing patch of thick skin that looks like a scar

Early melanoma

This early melanoma could be mistaken for a mole, so its important to look carefully at the spots on your skin.

Possible Signs And Symptoms Of Melanoma

The most important warning sign of melanoma is a new spot on the skin or a spot that is changing in size, shape, or color.

Another important sign is a spot that looks different from all of the other spots on your skin .

If you have one of these warning signs, have your skin checked by a doctor.

The ABCDE rule is another guide to the usual signs of melanoma. Be on the lookout and tell your doctor about spots that have any of the following features:

• A is for Asymmetry: One half of a mole or birthmark does not match the other.
• B is for Border:The edges are irregular, ragged, notched, or blurred.
• C is for Color:The color is not the same all over and may include different shades of brown or black, or sometimes with patches of pink, red, white, or blue.
• D is for Diameter:The spot is larger than 6 millimeters across , although melanomas can sometimes be smaller than this.
• E is for Evolving: The mole is changing in size, shape, or color.

Some melanomas dont fit these rules. Its important to tell your doctor about any changes or new spots on the skin, or growths that look different from the rest of your moles.

Other warning signs are:

• A sore that doesnt heal
• Spread of pigment from the border of a spot into surrounding skin
• Redness or a new swelling beyond the border of the mole
• Change in sensation, such as itchiness, tenderness, or pain
• Change in the surface of a mole scaliness, oozing, bleeding, or the appearance of a lump or bump

How Do I Know If I Have Melanoma

You can easily identify the signs by using the ABCDE approach.

A Asymmetry

Your suspicious skin lesion does not look quite similar when comparing both left and right sides or both top and bottom sides.

B Irregular Border

If you draw a line along the boundary formed between your healthy skin and your suspicious skin lesion, youll notice that it does not resemble a circle or oval shape.

C Color variations

Look out for it usually has a mixture of skin colours such as black, red, white, blue, and brown.

D Diameter

If the suspicious skin lesion grows larger than 6mm in diameter, this can potentially be an aggressively growing melanoma.

E Elevated surface

If you look at the skin lesion from a view along you skin surface, a raised or elevated skin lesion could be a clue of this form of skin cancer.

Other signs that are suggestive of a melanoma are itchiness, bleeding skin lesion, and skin ulcers. Also, if it spreads to internal organs, one may experience signs and symptoms related to the affected organ.

If you have any of these warning signs, seek help from a dermatologist immediately. Your doctor will examine you for any suspicious skin lesions and take some skin sample for testing. Your doctor may also further investigate with imaging techniques such as x-ray to find out the extent of the disease spread.

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.

Most moles, brown spots and growths on the skin are harmless but not always. The ABCDEs and the Ugly Duckling sign can help you detect melanoma.

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.

Amelanotic Melanoma: It Doesnt Look Like Other Melanomas

Odds are, if you have spent time on SkinCancer.org, you know the classic ABCDE warning signs of melanoma: Asymmetry, Border irregularity, Color variations, Diameter over ¼ inch or Dark in color, and Evolution or change. But did you know that some melanomas have very different features?

For example, certain melanomas may have no color at all. Physicians refer to these as amelanotic melanomas, because they are conspicuously missing melanin, the dark pigment that gives most moles and melanomas their color. These unpigmented melanomas may be pinkish-looking, reddish, purple, normal skin color or essentially clear and colorless.

• An example of a flat, amelanotic, superficial spreading melanoma on the leg.
• A nodular melanoma developing within an amelanotic melanoma in situ on the scalp.

While these melanomas lack pigment, they may have other melanoma warning signs to stay on the lookout for, such as asymmetry and an irregular border. In addition, more and more physicians today stress the importance of the E in the ABCDEs evolution or change. The Skin Cancer Foundation recommends that you examine your skin head to toe every month, especially looking for any new mole or any sign of change in an existing mole. If you spot any change that you consider suspicious, see a skin specialist without delay.

To help you spot unusual melanomas, you can also use early recognition strategies beyond the ABCDEs, such as the Ugly Duckling sign.
