Abnormal Growth
A mole is an abnormal spot very small, which grows on the skin. It is a benign lesion composed of melanocytes, cells that produce skin pigment. They may appear singly or in groups, with each mole has different growth pattern, but not all brown spots on the skin are moles.
Everyone has moles. Some are born with more and develop new ones until age 30, including up to 40. The vast majority of people have between ten and thirty spots. Some people are born with a predisposition to them, in some cases it is a family-genetic trait.
A normal mole has sharp edges, round or oval shape, is flat or rose, and often has different sizes, but usually is less than 0.63 inches in diameter. The color of the moon can vary from pink or very light brown to dark brown. As the years pass, some moles may increase in size, acquire a clearer, and pale. This change is especially noticeable in the face. They can also increase because of sun exposure. At some stages of life often, grow in number and size, as occurs during puberty and pregnancy.
In general, most moles appear during the first 30 years of life. It is very important to pay attention to those that arise after that age and make them see a dermatologist. Another crucial point is to observe any changes occurring in a preexisting mole. If it bleeds, itches, is growing too fast, so scaly or crusted, you must go to the specialist to observe and perform the clinical examination. The same applies to the case of a sore that does not heal or not heal small wounds.
Some moles can become the gateway for skin cancer. There are different types of skin cancer. Melanoma is one of them. May begin as a mole or in an area that changes its appearance. Are the least common of skin cancers, but the most aggressive and therefore the more dangerous?
The spots were examined clinically with different tools. Definitive diagnosis may be required to do a biopsy, removing a mole and examined under a microscope. If they are not examined, cells from the skin can spread to other tissues and organs.
Atypical moles or large should be examined by a dermatologist annually and / or to any change. Those with increased risk of skin cancer should regularly check their moles. Additionally, we recommend the entire population to avoid excessive sun exposure and use sunscreen with an SPF of greater than 15.
Most skin cancers develop in those parts of the body permanently exposed to sunlight, head, tips of the ears, neck, face, hands, shoulders, forearms. In men must also pay attention to the chest. In women, lesions may appear in the lower back and legs.
