Why have some people have so many moles?

The moles, which occur when the pigment cells called melanocytes gather together, are very common. Most people have 10 to 40 moles on their skin, especially on areas exposed to the sun. The number of moles you have depend on factors such as your genetics, sun exposure or hormonal changes.

If you have a lot of moles – or new or changing moles – it is important to monitor your skin. Most moles are not cancerous, but people with 50 or more moles can be at an increased risk of skin cancer.

Anyone can get mole, although lighter skin tend to have more moles than darker skin, especially if they spend time in the sun.

People with clear skin have less melanin, a pigment that protects your skin from the sun. Darker skin people have more melanin, and this additional sun protection may be the reason why they are less likely to develop as many moles.

Researchers do not fully understand why people are developing new moles, but they have found that certain factors can increase the chances.

• Exposure to the sun: Exposure to ultraviolet rays (UV) of the sun or a tanning bed can cause new moles. UV rays cause melanocytes to produce more pigments to help protect the skin. This new pigment can come together to form new moles.
• Age: Most people are developing new moles during childhood to forty. Older adults tend to have less moles than children, adolescents and young adults.
• Family history: Taupes tend to run in families. If you have family history of mole, light skin or light hair, you are more likely to develop moles during childhood and adolescence.
• Genetic: Some genetic mutations may increase the risk of benign (non -cancerous) or the risk of melanoma.
• Hormonal changes: It is also common to develop new moles in times of hormonal changes, such as puberty or pregnancy.

Ordinary moles are generally harmless. But about 1 out of 10 adults in the United States has at least an atypical or unusual mole. These moles, also called Dysplasic neviare more likely that ordinary moles of developing in an aggressive form of skin cancer called melanoma.

To determine if you have an atypical mole that is at high risk, consult a dermatologist (a doctor specializing in the treatment and diagnosis of skin conditions). They can assess the size, shape and color of the mole to determine if additional tests are necessary.

To search for signs of melanoma, you and your doctor can use the ABCDE rule:

• A for asymmetry: The taupe has an unusual shape and half does not correspond to the other.
• B for the border: The edges of the mole are shredded and unequal.
• C for color: The color of the mole is uneven and can change over time. Unusual colors may include black, red, blue, white or pink.
• D For diameter: The mole is wider than 6 millimeters (about the width of a pencil gum).
• E to evolve: The color, shape or size of the mole has changed over time.

How to prevent melanoma

It is not always possible to prevent melanoma, but you can help reduce your risk by protecting your skin from UV rays from the sun. These tips can help:

• Wear a sunscreen every day.
• Wear a long -sleeved hat and shirt when you spend time in the sun.
• Make frequent breaks in the shade.
• Wear sunglasses to protect your eyes.
• Avoid tanning beds.

Consult a doctor or dermatologist if you are concerned about a new or changing mole and that he may become cancer. Early detection is important. Melanoma at an early stage is treatable and your dermatologist can eliminate the moles before the propagation of cancer.

The monitoring panels include:

• A new mole that has developed in adulthood
• A mole that changes color, shape or size
• A mole that has an open wound that does not heal
• A mole with rough or raised edges

Taupes are growth on the skin that develop when pigmented cells called melanocytes come together, causing dark areas. Exposure to UV sun rays is a common risk factor to develop moles. Among other factors, he can explain why you have several moles of grains.

Most moles are considered ordinary and benign. However, atypical moles can be a sign of skin cancer. Consult a doctor if you are developing a new mole in adulthood or notice that one of your beauty grains changes in color, shape or in size.
