If we continuously Googled potential cancer symptoms , we would probably risk falling ill with paranoia and having to rely on a psychologist if not a psychiatrist . In reality, what we should do is calmly focus on the proven information and the result of scientific studies:

One example comes from Russian oncologist Mikhail Myasnyankin related what to look for during a manicure . According to the expert, the main sign of oncology that can be seen on the nails is the appearance of stripes of different shades , from brown to black , in the nail bed area :

It is also worth noting the sudden brittleness of the nails and the appearance of cracks . If you remember that you did not injure your nail, but a spot appeared on it , it is best to contact a specialist. But don’t panic at the sight of any spots: Myasnyankin explains that there are many benign formations that have the same symptom . The expert also called the application of gel polish, i.e. exposure to ultraviolet radiation , one of the possible triggers that can lead to cancer.

How a gel polish lamp can cause cancer:

Scientists agree with the oncologist, comparing the risk from such devices with mini tanning beds, which have long been recognized as harmful. We’ve found out if you need to urgently stop putting gel polish on your nails, and answered some popular and scary questions about cancer.

Bioengineers and oncologists at the University of California San Diego have studied ultraviolet nail lamps. They drew attention to cases of finger skin cancer in beauty pageant participants. The fact is that devices that emit ultraviolet rays, similar to mini tanning beds, are standard devices in any nail salon. They are used to harden chemicals – nail gels. The emission spectrum of these dryers is 340-395 nanometers, in contrast to conventional solariums (there, an indicator of 280-400 nm was recognized in previous studies as a carcinogen). The dryers are still considered safe, although scientists have not conducted any experiments with their radiation. The study authors conducted an experiment:

they used three types of cells: keratinocytes and fibroblasts from adult skin, as well as embryonic fibroblasts from mice. All cell lines were placed in a nail dryer and exposed to ultraviolet radiation: 20 minutes a day for three days, then 20 minutes with an hour off. The result is amazing: even a 20-minute session led to the death of 20-30% of cells, and regular procedures destroyed 70%.

“We have seen that DNA becomes damaged and some of the damage does not repair itself over time, leading to mutations after each exposure to a UV nail polish dryer. Finally, exposure can cause mitochondrial dysfunction, which leads to further mutations ,” said Professor Lyudmil Aleksandrov . According to the professor, skin cancer patients show the same mutation patterns seen in irradiated cells. The authors note that it is A long-term epidemiological study is needed to evaluate the risk of developing cancer.However, scientists insist that the harmful effects of the device are already evident.
