The Causes Of Melanoma

ABCDEs Of Skin Cancer

Melanoma is often the result of your exposure to the suns ultraviolet A and ultraviolet B rays of light. These rays contain radiation from the sun, which travel through the atmosphere and are responsible for melanoma and other skin conditions, such as premature aging and damage to your eyes.

While anyone can develop melanoma, you may be at increased risk for skin cancer if you have a family history of the condition. Other risk factors for melanoma include:

  • Frequent sunburns
  • Immune system dysfunction
  • Spending a lot of time in the sun

Because the suns light rays cause skin cancer, its important that you always wear a high-quality, protective sunscreen that blocks these rays from damaging your skin.

Melanoma

While melanoma is not the most common skin cancer, it is responsible for the majority of skin cancer deaths. Melanoma develops when the cells that give skin the tan or brown color begin to grow abnormally out of control. Melanoma is caused by a variety of factors, including exposure to UV rays from the sun and tanning beds, but genetic and environmental factors can play a role as well.

Approximately 100,350 cases of melanoma will be diagnosed in the U.S. this year. Around 60% of those are in men. Anyone can get melanoma, however, if detected early, cure and survival rates dramatically improve. The most important warning sign of melanoma is a new spot on the skin or one that is changing in size, color or shape. This is why it is so important to do a monthly self skin exam and to have your health care provider examine your skin once a year. The following ABCDEs of skin cancer provide a good guideline. Any abnormalities should be reported to your health care provider immediately.

What Can I Do To Reduce My Risk Of Skin Cancer

Protection from ultraviolet radiation is important all year, not just during the summer.

Most skin cancers are caused by too much exposure to ultraviolet rays. UV rays come from the sun, tanning beds, and sunlamps. UV rays can damage skin cells.

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.

The Abcde Rule Of Skin Cancer

Checking your skin for suspicious changes can help identify melanoma in its earliest stages. This, in turn, can increase your chance for successful treatment.

The ABCDE Rule of skin cancer is not meant to be a tool for diagnosis but rather one by which individuals and healthcare providers can differentiate between a problem growth and a simple, everyday blemish.

The ABCDE Rule is broken down as follows:

Colour Variability And Changing Colour

C is for Colour variability.

A melanocytic naevus usually has a single shade of colour or two colours with one occurring inside the other or regularly repeated .

Variation in colour of melanocytic naevi

Melanoma can be brown but can have as many as five or six colours such as blue, black, tan, grey, pink, and red: 50% of melanomas include these uncommon colours. These colours are unevenly or irregularly distributed. C is also for Changing Colour.

Skin Cancer Signs: The ABCDEs of Melanoma

To check your skin, use a full-length mirror to examine your entire body, front and back. Then, raise your arms and look at your right and left sides.

Bend your elbows and carefully check your forearms, underarms and palms. Look at the backs of your legs and feet, between your toes, and the soles of your feet. With nail polish removed, check your fingernails and toenails, as well.

Use a hand mirror to check the back of your neck and scalp, and part your hair for a closer look. Finally, check your back and buttocks with a hand mirror. Ask a partner to help check your back and other hard-to-see areas.

What Other Skin Lesions Might Have Abcdefg Features

The ABCDEFG criteria are not very specific for melanoma, as some or all of the criteria may be displayed by another skin cancer, such as a pigmented basal cell carcinoma or pigmented squamous cell carcinoma.

Malignant melanoma mimics

A benign lesion can be asymmetrical in shape, have an irregular border, colour variation, and be different. Examples include congenital melanocytic naevus, atypical melanocytic naevus, solar lentigo, or seborrhoeic keratosis.

Melanocytic naevi can also evolve in some circumstances such as darkening after exposure to the sun, during pregnancy, and become more elevated with age seborrhoeic keratoses and solar lentigines routinely evolve over time.

Clinicians trained in dermoscopy can often correctly diagnose skin lesions, but sometimes a biopsy will be needed to confirm a diagnosis.

What Should I Look For When Examining My Moles

Examine your skin with a mirror. Pay close attention to areas of your skin that are often exposed to the sun, such as the hands, arms, chest, and head.

The following ABCDEs are important signs of moles that could be skin cancer. If a mole displays any of the signs listed below, have it checked immediately by a dermatologist:

  • Asymmetry: One half of the mole does not match the other half
  • Border: The border or edges of the mole are ragged, blurred, or irregular
  • Color: The mole has different colors or it has shades of tan, brown, black, blue, white, or red
  • Diameter: The diameter of the mole is larger than the eraser of a pencil
  • Evolving: The mole appears different from others and/or changing in size, color, shape

Keep in mind that some melanomas may be smaller or not fit other characteristics.You should always be suspicious of a new mole. If you do notice a new mole, see your dermatologist as soon as possible. They will examine the mole and take a skin biopsy . If it’s skin cancer, a biopsy can show how deeply it has penetrated the skin. Your dermatologist needs this information to decide how to treat the mole.

The most common location for melanoma in men is the back in women, it is the lower leg.

What You Can Do

Check yourself: No matter your risk, examine your skin head-to-toe once a month to identify potential skin cancers early. Take note of existing moles or lesions that grow or change. Learn how to check your skin here.

When in doubt, check it out. Because melanoma can be so dangerous once it advances, follow your instincts and visit your doctor if you see a spot that just doesnt seem right.

Keep in mind that while important, monthly self-exams are not enough. See your dermatologist at least once a year for a professional skin exam.

If youve had a melanoma, follow up regularly with your doctor once treatment is complete. Stick to the schedule your doctor recommends so that you will find any recurrence as early as possible.

What Are The Four Main Types Of Melanoma Of The Skin

Superficial spreading melanoma

What you should know: This is the most common form of melanoma.

How and where it grows: It can arise in an existing mole or appear as a new lesion. When it begins in a mole that is already on the skin, it tends to grow on the surface of the skin for some time before penetrating more deeply. While it can be found nearly anywhere on the body, it is most likely to appear on the torso in men, the legs in women and the upper back in both.

What it looks like: It may appear as a flat or slightly raised and discolored, asymmetrical patch with uneven borders. Colors include shades of tan, brown, black, red/pink, blue or white. It can also lack pigment and appear as a pink or skin-tone lesion .

Lentigo maligna

What you should know: This form of melanoma often develops in older people. When this cancer becomes invasive or spreads beyond the original site, the disease is known as lentigo maligna melanoma.

How and where it grows: This form of melanoma is similar to the superficial spreading type, growing close to the skin surface at first. The tumor typically arises on sun-damaged skin on the face, ears, arms or upper torso.

What it looks like: It may look like a flat or slightly raised, blotchy patch with uneven borders. Color is usually blue-black, but can vary from tan to brown or dark brown.

ABCDE

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.
