Students create cheap, portable device to detect skin cancer
A skin change is often the first warning sign of melanoma. Skin cancer can be of various types, sizes and depth and is considered the most incident type of tumor in the population - about 25% of human body cancers are skin.
Early diagnosis of skin cancer increases chance of treatment success. To facilitate and accelerate this process, engineering students at McMaster University, Canada, have developed an inexpensive and user-friendly device that helps detect the condition.
Named sKan, the device when attached to the skin measures the temperature so that immediately and accurately identify the presence of melanoma. For this to happen, the product applies a cooling to the skin and records how long it takes to return to its initial temperature.
"Cancer cells have a higher metabolic rate than normal cells, and therefore release This means that after the heat shock is applied, the cancerous tissue will recover heat faster than non-cancerous tissue, indicating a strong likelihood of melanoma. "
The collected data is then passed to a computer and displayed in the form of a heat map and a time chart. Then, the combination of these results would show the presence or absence of melanoma. Currently, the sKan device has a forecast of a cost of $ 1,000, which is considered little compared to other methods.
The work of the team led the students to the position of winners of the James Dyson Award, an international design award that celebrates the inventions of college students with the goal of inspiring the next generation of students.
The next step of the team is to get approval from the Food and Drug Administration, the agency that regulates medical devices in the country. The idea is that in the future sKan will be used on a large scale and can detect more than 130,000 cases of melanoma per year.
"Regardless of adopting best oral health practices, such as brushing teeth, al and visit the dentist more often, postmenopausal women in general tend to show more dental loss than men of the same age, "says Xiaodan Mai, PhD student in epidemiology at the Department of Social and Preventive Medicine at the Faculty of Public Health and Professions of Health and one of the authors of the study.
Only in Campinas, in the interior of São Paulo, cases of mumps have increased by 304% in recent months, according to the Health Department. is 10 times higher than in 2015. In São José do Rio Preto, also in the interior of São Paulo, 18 meningitis cases occurred in only 10 days. In the Federal District, cases of the disease are 75% higher than in 2015, according to data from the Department of Health.
