Birthmarks and Moles - Brown spots on the skin
We all have spots on the skin. Some are already at birth, while others show up only at puberty or later - birthmarks occur and disappear over the life course. On average, an adult is about 25 moles. A melanoma often starts as a small brown stain that within a few years grow to a size of a few millimeters in diameter. Most moles stop growing when they reach this size. Some may begin to grow in thickness, so that they become little brown buds. A mole is a collection of the pigment in the skin cells. The pigment cells are those cells which give the skin color and protects against the sun's ultraviolet radiation. There is seldom reason to remove brown spots, but still chooses a part due to physical discomfort or for cosmetic reasons, to remove birthmarks by a small operation. Most birthmarks are harmless, but some can be converted to malignant skin cancer. The risk of skin cancer increases with the number of sunburn and extensive sun exposure. You should absolutely not scratch or even try to remove a birthmark.
A birthmark is a benign irregularity on the skin which is present at birth or appears shortly after birth, usually in the first month. It is said that around 1 in 10 babies will have a birthmark. The two main types are: Vascular birthmarks (often red, pink or purple) caused by abnormal blood vessels in or under the skin and Pigmented birthmarks (usually brown) caused by clusters of pigment cells. Vascular birthmarks usually occur in the head and neck area, mainly on the face. However, both types of birthmark can appear anywhere. Pigmented birthmarks are tan or brown coloured skin marks.
Skin Pigmentation Disorders
Skin pigmentation disorders result in an abnormal darkening or lightening of the skin. Normal marks on the skin itself is completely harmless, but it is important to keep an eye on the parent brand is changing appearance, or whether there are new moles, since changes can sometimes be a sign of melanoma. Malignant tags will often be asymmetrical in combination with an irregular edge, multiple colors, and a mole larger than 6 mm. It is estimated that ultraviolet rays from the sun causes virtually all cases of melanoma.
Signs of Malignant melanoma (Skin Cancer)
The most important signs of melanoma (malignant melanoma) is that the mole changes its appearance by changing color, shape, surface or size. Or that the mole starts to itch, it feels different or form ulcers or if appearing moles on the palm or foot. There may be completely harmless changes in the mole, but there may also be the incipient melanoma. Any changes, if any, occurs relatively quickly, within a few weeks or months. You should always consult a doctor if you have a birthmark, which will shortly change the appearance. The sooner the mole is treated, the greater the chances of cure.
Melanoma is a malignant tumor of melanocytes. Melanocytes are cells that produce the dark pigment, melanin, which is responsible for the color of skin. Melanoma cancer affects every year thousands of people. If the cancer has time to evolve, it spreads to other parts of the body where it can be life threatening. However, if melanoma is detected and surgically removed in time, there are good chances of being completely cured.
Studies show a strong correlation between solar ultraviolet radiation and melanoma. People with fair skin, blonde or red hair, blue or green eyes are most at risk of developing melanoma or malignant melanoma of the eye for example. The risk is also increased by excessive sun exposure and use of the solarium. Conversely seen melanoma almost never in people with very dark skin is better protected from the sun's harmful rays. Use of the solarium leads predominantly irradiation with UVA rays.
