Differentiating Normal Flies and Skin Cancer Moles

Almost everyone has at least one mole on their body.

Moles often appear in childhood. If you are born with a mole, these spots are considered birthmarks. Birthmarks are the result of color pigmentation of melanocytes (skin pigment cells) that clump together for no apparent reason.

These skin conditions are generally harmless, however, some moles can turn into cancer.

How to distinguish normal moles and symptoms of skin cancer

Unusual forms, wounds, bumps, suddenly appear unnoticed, or changes in appearance or sensation in the area of ​​the skin may be a sign of melanoma or other types of skin cancer - or as an early warning.

Normal moles

Normal birthmark moles are usually evenly colored - brownish, blue-gray (Mongolian spot), reddish (salmon patches), purplish (hemangioma), jet black. People with skin or dark hair tend to have darker moles than those with white or blonde hair.

Moles can blend evenly with the skin or appear raised, even with hair growth. The shape can be perfectly round or oval. Normal birthmarks are generally less than 6 millimeters in diameter (as wide as an eraser on the tip of a pencil).

Some birthmarks can be present when you are born, but most appear during childhood or early adulthood. After the mole develops, they will usually still have the same size, shape, and color for years.

Some moles may darken (during pregnancy), increase (during adolescence), or fade (in old age: 40-50 years and above) in response to hormones. When you reach adulthood, you may have 10 or more birthmarks on your body.

Moles that only appear later should be examined by a doctor.

Skin cancer sign moles

The most important warning sign of melanoma is a new mole that appears on the skin (early adolescence).

Melanoma, one of the most deadly forms of skin cancer, may begin as a flat mole and eventually expand. In rare cases, the skin condition may not be pigmented.

The "ABCDE" guideline is another way that can make it easier for you to distinguish anywhere that is a classic sign of melanoma. If you have one of the warning signs below, immediately notify your doctor to get the right diagnosis.

A for Asymmetry (Asymmetry)

Normal moles have a perfectly symmetrical shape, where one edge will match the other. Birthmarks suspected of being a symptom of skin cancer will have incompatibility in size and shape. This is because the cell on one side grows faster than the other. Cancer cells will tend to develop faster than normal cells, and in irregular patterns.

B for Border

The margins of a normal birthmark will have defined boundaries, separate clearly where your skin color ends and where the color pigmentation due to a mole starts.

If the edges of the birthmark appear blurry - like someone who is coloring outside the line - this can be a sign of cancer. Ragged or opaque edges are also caused by uncontrolled cancer cell growth.

C for Color (


As long as the color remains solid, equally flat on all sides, your mole is normal and there is no need to worry. However, if you see a variety of shades in one area of ​​the mole, your birthmark can be cancerous.

Melanoma will be shaped like a patch that has different shades of color from one color family. For example, in the middle of a pink that gradually darkens reddish on the edges, or the opposite (only red or pink moles are normal). Or, a cancer mole can show completely different color spots in one place, such as red, white, gray in a mole.

D for Diameter

Normal birthmarks will remain the same size all the time. A mole that grows suddenly, larger than 6 mm, can indicate a problem. However, melanomas are also sometimes found in smaller sizes than they should.

E for Evolving

Change is a bad sign when talking about birthmarks. Moles change color, size, shape so that they look very different than all other moles on your skin indicating that this is the time for you to see your doctor.

It is also important to carry out regular self-skin checks to monitor birthmarks that have growth or suspicious changes in color or shape.

Beyond the ABCDE guidelines, also pay attention to any other differences that may appear on your birthmark - such as redness, scaling, bleeding, pus out, swelling outside the edges of moles, itching, pain, or pain when touched.

In addition, note the three characteristics below:

  • There are more than 100 moles in your body
  • Most are more than 8 mm
  • Most are atypical

If you have three characteristics of this mole, called "classic atypical mole syndrome", you are at high risk for developing melanoma. Your chances will increase dramatically if you not only have this syndrome, but also have close family members (level one or two) who have melanoma. While atypical birthmarks often occur in childhood, they can appear at any time in life in people with this condition.
