Number of cases of melanoma growing

Number of cases of melanoma growing

According to the National Cancer Institute (INCA), 6,230 new cases of melanoma, a serious type of skin cancer, are expected in Brazil this year. Although alarming, the estimate only reaffirms what a new study by the Mayo Clinic showed in the United States. The research, published in the April issue of the Mayo Clinic Proceedings , points out that disease rates are increasing, especially among women between the ages of 20 and 40. The team of researchers, coordinated by the dermatologist Jerry Brewer, used data from the

Rochester Epidemiology Project , which computes information from treated patients in Olmsted County, Minnesota. We evaluated the cases of people diagnosed with skin cancer for the first time when they were between 18 and 39 years of age from 1970 to 2009. The results showed that, although the rates of this cancer are generally higher among men, in the selected age group, cases of melanoma are more common among females. They found, for example, that the incidence of the disease increased eightfold among women and four times among men aged 18-39 years in the last 40 years.

For the study coordinator, an explanation for the increase in problem among women is the growth of tanning chamber use. Those who are adept at this treatment have a risk of up to 74% greater than developing melanoma.

Truths and lies about the tanning chambers

The controversy of the tanning chambers continues. Anvisa has banned the device for both commercialization and personal use, relying on research from the International Agency for Research on Cancer. Researchers point out that people under 35 who are exposed to artificial tanning of these chambers are at 75% more risk of developing skin cancer.

The device functions as an artificial sun, emitting UVA rays, stimulating the production of melanin, which produce pigmentation and give the tan to the skin. If the chambers are really active again, be aware of truths and lies about it.

Can cause skin cancer

True. WHO studies say that exposure to UVA lamps increases the risks of developing melanoma, a more serious form of skin cancer, by 75% by damaging the skin cells. "In general, those who are accustomed to tanning also like sun exposure, which further damages the skin cells," explains Meire Brasil Parada, a dermatologist at the Unifesp Cosmiatry Unit (SP). Another error that raises the risks is not to use sunscreen when using the cameras.

Preserves the hydrated skin

Myth. According to the specialist, light promotes cell atrophy, decreasing skin hydration and increasing water loss. "In addition, exposure damages collagen, causing the skin to lose elasticity and tone."

Causes premature aging of the skin

Truth. The lack of hydration, damaged cells, destroyed collagen and loss of elasticity causes the skin to become aged, with early wrinkles appearing.

30 minutes of chamber are equivalent to 30 minutes of sun exposure

Myth. According to the dermatologist, 10 minutes in a tanning chamber are equivalent to five times the same time of sun exposure on a hot day, during hours of intense solar radiation.

Lack of time control can cause burns

True. There is a test to determine the time of exposure to light called DEM (Minimum Erythematosus Dose). The test checks how much light exposure the skin becomes red. A camera operating under normal and supervised conditions can not cause burns. "It is UVB radiation and not UVA that is primarily responsible for sunburn," explains Carla Albuquerque, dermatologist and MyVida specialist. "However, as there is no rigid regulation that controls the manufacture and inspection of these machines, there is little to be said about the credibility of this source of light emission," adds the specialist.The use of medications does not influence the use of the

Myth. According to Carla Albuquerque, there are medications that are photosensitizing and, in the presence of ultraviolet radiation, can cause serious reactions to the skin. "Piroxicam, tetracyclines, promethazine and griseofulvin are some examples," he says.


Vaccination is the best way to prevent diseases

Vaccination is the best way to prevent diseases

Vaccination is the act that most reduces diseases and deaths worldwide, for that reason, should be part of the day to day of the people in general. The subject should also be discussed in the routine visits to the gynecologist, since it is often the only medical contact for the woman during the year.

Circulation . For more than 11 years, scholars have followed a group of 52,610 men and women. Each individual responded to questionnaires reporting the difficulty of falling asleep, the frequency they woke up and could not get back to sleep, and the number of times they awoke with the feeling of sleeping poorly, among other approaches.
