What Causes Moles To Suddenly Appear?

Ever wondered what causes moles to suddenly appear? All individuals have moles in varying parts of their bodies.

It is estimated that on average, the normal person has at least ten moles on their skin. However, the number does not go beyond 40 moles, and moles can emerge on any part of your body. Those who are in their early 20s are more likely to experience the emergence of moles.

Mole patterns on your skin are in many cases determined by your genes. However, there are other external factors such as exposure to UV radiation, which may cause the appearance of more moles. Additionally, these UV rays can cause the moles that are already present to darken. Existing moles also tend to darken during pregnancies and during the teen years.

Skin Moles—How Many Types Are There and What Causes Moles to Suddenly Appear?

If you suddenly notice a mole on a certain region of your body, you will undoubtedly start to wonder whether the mole is harmless or whether it warrants a visit to your physician. Moles will in many cases appear as small, brown spots on your skin surface that can take on varying colors, sizes and shapes.

Based on its color, shape and the time when it first started developing, the mole may fall into one of the following categories:

  • Congenital Moles: Any mole that is present when a child is born is referred to as a congenital mole. Close to one percent of the world’s population has this type of mole, and it is a mole that has an increased risk of developing into skin cancer.
  • Atypical Moles: They are also referred to as dysplastic nevil, and they tend to be bigger than pencil erasers. Atypical moles are easy to identify due to the fact that they are irregularly shaped. Their color is uneven and will normally be characterized by the presence of a dark brown color at their center. Their borders are irregular, and will normally have a reddish color accompanied by black, uneven dots around the edges. These are moles that traditionally run in a family and have an increased chance of developing into full-blown skin cancer.
  • Acquired Moles: These are the most common and account for the highest number of moles seen in the world today. Many of them develop during early adulthood or during childhood years. An acquired mole will normally be small in size, and will typically be less than a quarter inch. Medical experts believe that these moles come about due to excessive exposure to the sun rays. The good news is that many of these moles do not turn into skin cancer.

Sudden Appearance of Moles and their Relation to Melanoma

Unusual markings, moles, blemishes, lumps and sores in a particular region of your skin could be an indication that you have developed melanoma, or another form of skin cancer. It may also be a warning that skin cancer may develop at any moment.

Having looked at the signs associated with normal moles, it is important to now look at the symptoms associated with melanoma.

For melanoma, its most important indication comes in the form of a new spot that has emerged on your skin. It can also be seen when a spot that was previously present changes its color, shape or size. Another important indication is noticing a spot that is not similar to all the others currently present on your skin surface. This is also called the ugly duckling symptom.

If you notice any of the signs mentioned above, make it a point to visit a physician. Another guide to use when checking for melanoma is the ABCDE rule. Here, you need to look for spots that contain features such as:

  • A—Asymmetry: Occurs when one part of the mole is not similar to the other part.
  • B—Border: A mole has edges that are blurred, irregular, notched or ragged.
  • C—Color: The mole does not have a uniform color. You may notice black and brown shades, that may be accompanied by blue, white, red or pink patches.
  • D—Diameter: Refers to a spot that is bigger than six millimeters. You should, however, note that some melanoma spots tend to be much smaller than this.
  • E—Evolving: The spot is changing its color, shape and size.

There are melanomas that do not fit the description above, hence the need to inform your doctor of any spots or changes taking place on your skin. You should also point out any growths that appear to be different from the rest on your body.

Additional signs to check include:

  • Sores that have refused to heal
  • A mole that has changed its surface
  • A pigment that has started spreading from the mole’s border and into the skin surrounding it
  • A change in the sensations being experienced, e.g., pain, tenderness and itchiness
  • Swelling or redness that spreads beyond the spot’s borders

Is It Possible for a Cancerous Mole to Disappear?

Your body’s immune system will start fighting back when it is attacked by cancerous cells. In some cases, the immune system may succeed in fighting it and be able to reduce the size of this cancerous mole. In such cases, you may find that the mole has disappeared completely. The process is typically referred to as regression. Regression normally occurs in ten to twenty percent of all reported melanoma cases.

For individuals whose cancer has not spread to other areas of the body, regression may be good as it can completely get rid of the cancer. However, in the event that the cancer had already metastasized in other areas of your body, a mole’s disappearance will not be an indication that the cancer has left the other parts of the body.

A Disappearing Mole—When Should You Consult Your Doctor

You need to ensure that any mole that is changing its color or constantly disappears before reappearing again is looked at by your doctor. Some moles are harmless and may disappear from time to time, but you need to sit down with your doctor so that he/she can be able to rule out the presence of other health conditions.
