A nevus is commonly called a mole. Moles (nevi, the plural of nevus) in which the skin cells are growing unusually are called atypical, or dysplastic, nevi. These moles may be noncancerous (benign) but may be considered one step closer to being cancerous (malignant) than a typical mole. All moles are made up of collections of the pigment-producing cells of the skin; they may be flat, raised, skin-colored, or pinker or darker than the skin. Atypical moles are characterized by having abnormal cell growth, but this is not always obvious from looking at the mole, and a doctor may have to biopsy the mole and look at a portion of it under a microscope to make this diagnosis. It is important to show all your moles (particularly those that are new or rapidly changing) to your doctor because these atypical nevi are sometimes considered an early form of cancer.
A nevus is commonly called a mole; moles can be noncancerous (benign) or cancerous (malignant), present at birth (congenital) or develop after birth (acquired). Some moles are raised and some are flat, and they can range in color from skin-colored to pink, tan, brown, black, or even blue. Regardless of these differences, all moles are made up of collections of the pigment-producing cells of the skin. It is very difficult to look at a mole and know if it is cancerous or not. Some signs of malignancy include large size (bigger than a pencil eraser), rapid growth or change, multiple colors in one mole, or unusual shape. You should show any mole that you are concerned about to your doctor.
Telangiectasias are widely open (dilated) blood vessels in the outer layer of the skin. When seen on the legs, they are often called spider veins.
Ethnic skin is a term used to indicate a person with olive or darker skin who tans easily. Patients with dark skin often display fewer signs of aging than similarly sun-exposed whites and, therefore, may require a different approach. Medical advances in dermatology have made it possible for people with darker skin types to benefit from many cosmetic procedures that were formerly only available to lighter-skinned patients.Some of available procedures that can be done for ethnic skin are as follows:Botulinum toxin injection (Botox®) Microdermabrasion Chemical peels Injectable fillers Many laser treatments (eg, laser hair removal)
Keratoacanthoma (KA) is a rapidly growing skin cancer usually appearing as a volcano-like bump on the sun-exposed skin of middle-aged and elderly individuals. Many scientists consider keratoacanthoma to be a less serious form of squamous cell carcinoma. Most keratoacanthoma cause only minimal skin destruction, but a few behave more aggressively and can spread to lymph nodes.
Sunburn is damage to the top layers of the skin caused by overexposure to ultraviolet (UV) light. Most commonly, the light source is the sun, but tanning beds and some intense heat sources, such as welding tools, can also produce a sunburn. The sunburn usually becomes apparent within 24 hours of exposure; the skin becomes red, warm, and tender, and the person may feel dizzy or ill. Sometimes the skin may blister and peel.Experiencing a sunburn raises the lifetime risk of developing skin cancer. Sunburn and sun exposure also increase wrinkling and other signs of premature aging in the skin. Even a tan is dangerous to the skin, as many doctors consider a tan to be an early sunburn. The best protection is to avoid the sun, especially during the peak hours of 10 AM to 3 PM. Always wear sunscreen on exposed skin with an SPF of at least 30. Additionally, it is important to know that you can get a sunburn through certain clothing and that tanning beds are a source of the same light that cause burns, premature aging, and skin cancer.
Actinic keratoses, also known as solar keratoses, are small rough or scaly areas of skin due to damage from sun exposure. Some actinic keratoses can turn into squamous cell skin cancer, so it is important to perform self-examinations often and catch them early.
Skin cancer is the most common cancer in the United States, and it is the sixth most common cause of cancer death in the United States. Melanoma is the least common of the skin cancers (the other types are squamous cell carcinoma and basal cell carcinoma), but it is the most serious. It can be life threatening if it spreads (metastasizes) to other parts of the body. The frequency of diagnosis of melanoma has been increasing in recent years, faster than any other cancer.Melanoma starts in the color-producing cells of the skin and may develop in an existing mole or may occur as a new mole. Early diagnosis and treatment can lead to a complete cure, while advanced forms are likely to have a poor outcome. Advanced melanoma can spread to lymph nodes as well as other areas in the body, typically the lungs, liver, and brain.
A recent study published in the April issue of Mayo Clinic Proceedings reports that between the years 1979 and 2009, the incidence of melanoma increased eightfold among young women and fourfold among young men ages 18 to 39. “There is currently a melanoma epidemic in the U.S., particularly in young women and middle-aged men. This has been documented by various large population-based studies, with our study confirming that trend in young women,” said Mayo Clinic dermatologist Dr. Jerry Brewer.
On the second day of Christmas, try not to give the gift of artificial sun. Instead, give your loved one a bronzer, which can be applied over sunscreen, for a sun-kissed look without the skin damage!
The youngest legal age for using tanning beds has gone up from 14 to 18 years in California after Governor Jerry Brown signed a new bill into law. Beforehand, those aged between 14 and 18 were allowed to use tanning salon services if they had permission from their parents - not any more. For the first time anywhere in the USA, anybody under the age of 18 years is will be banned from using ultraviolet tanning beds and devices in commercial premises in the state of California. The new law (SB 746) will go into effect on the first day of 2012...
Before you head out to that sandy beach you may hit the gym or go on a diet to get your body bathing-suit ready. You may even consider going to a tanning salon to get a “base tan” before hitting the beach – this is NOT a good idea according to dermatologists!
In March of this year, the Indoor Tanning Association (ITA) purchased a full-page advertisement in The New York Times and released a television ad exhorting viewers to "go get a tan" because "your body will thank you," with images of indoor tanning beds - in use - flashing across the screen. A headline from one of their advertisements reads: "Tanning Causes Melanoma HYPE," and Sarah Longwell of the ITA claims that tanning is "just what the doctor ordered.
The summer is a great time to enjoy the sun and get some extra Vitamin D but it’s also a time when we sunburn the most. Not only can we get sunburn from a being outside on a sunny or cloudy day but we can also get burned from tanning salons. It’s the UV light from the sun and the tanning beds that gives us the tan and the burn. So what can we do about it?
Spring and summer are upon us and – with the lessons learned last summer long forgotten – you’re getting ready to head back to the beach. Instantly, you think before putting that sunscreen on that maybe if you just let your skin get a little bit tanned at the beginning of the summer, then you can avoid getting those painful pink burns and you can avoid smearing on gobs of sunscreen for the rest of the summer. Of all the stories I hear, this is the one that really troubles me the most. “Doc, I’m going to the tanning booth to get my base tan before summer starts,” or “But Doc, I burn badly once at the start of the season, but then I’m good to go until the fall.”
Exposure to ultraviolet (UV) radiation is the greatest cause of the most common skin cancers. UV radiation, in the form of light, can come either from the sun or from indoor tanning beds. Basal cell and squamous cell cancers, by far the most common types of skin cancer, are directly related to the total dose of UV light that the skin receives over a lifetime of exposure.
