What Causes Moles to Grow
The cluster of melnocytes that are unevenly distributed to give color to the skin caused moles to grow on some areas. Moles grow in singles or multiples and in various colors of red, brown or black. Generally benign, these moles can be caused by genes, heredity, hormone levels or age and the sun. The abnormal collections of melanocytes that caused moles to grow are usually normal, however on rare circumstances, they could become abnormal and cancerous. The skin pigmentation that caused moles to grow gets deeper into the layers of the skin and also alters its DNA causing malignant melanoma. Moles can be present at birth or may develop as the person grows older. Other skin moles just develop spontaneously without the person knowing it. Moles can appear and disappear with age and this is normal. However there are exceptional cases where moles remain in the skin and change its growth.
Most people have moles that are lighter in shade than their skin; however at some point these moles could become darker. The major reason that caused moles to grow this is too much exposure to the sun. Hormonal changes such as pregnancy or menopausal stage in a woman can also cause moles and skin pigments to appear on the skin. The skin that is over exposed to the sun's UV radiation caused moles to grow. The UV radiation is the most major risk factor that caused moles to grow and turn into melanoma. Moles that are present at birth and developed as the person becomes older have tendencies of turning into melanoma if there are chronic episodes of sunburn in childhood. The sun beds and tanning saloons also caused moles to grow and could develop into a malignant melanoma.
Family history of skin cancer also caused moles to grow. If your parents have moles there is a big possibility that you will also have moles. Most skin cancers are hereditary and if you have moles that look funny (dysplastic nevi), you should be examined and monitored regularly by a dermatologist. Certain types of genes are known to have caused moles to grow and develop into melanoma.
The best way to define what caused moles to grow is to identify the risk factors that should be avoided. Regardless of what caused moles to grow and become cancerous, everyone should know how to detect the early signs of moles that become cancerous. The so-called ABCD of moles is a guide to identify bad moles during self examination. The indications of melanoma include moles that have increased its size, has uneven border, irregular shape and have multiple colors. These are bad signs that the moles have become cancerous.
Most moles usually appear in the areas of the face, neck, back, legs and shoulders, chest including the least exposed areas such as bottom of the feet, arm pits and genital area. With UV radiation's damaging effect, it caused moles to grow and become cancerous. People should be proactive and aware about these risks to preserve a healthy skin. Tanning beds should be avoided as it has similar effects than the sun's UVR. People with fair complexion, red or blond hair, and blue eyes are most likely to develop melanoma sometime in their life. It is important to distinguish the risks and what causes moles to grow at an early stage.
