People with High Vitamin A Intake at Lower Risk of Skin Cancer

Vitamin A is known to be essential for the healthy growth and maturation of skin cells but prior studies on its effectiveness in reducing skin cancer risk have shown mixed results

Researchers have found that people who intake high levels of Vitamin A were 17 per cent less at risk of getting a skin cancer as compared to those who ate modest amounts of foods and supplements rich in Vitamin A.

“Our study provides another reason to eat lots of fruits and vegetables as part of a healthy diet. Skin cancer, including squamous cell carcinoma, is hard to prevent, but this study suggests that eating a healthy diet rich in Vitamin A, in addition to wearing sunscreen and reducing sun exposure, may be a way to reduce the risk,” said Eunyoung Cho, Associate Professor at the Brown University.

Vitamin A is known to be essential for the healthy growth and maturation of skin cells but prior studies on its effectiveness in reducing skin cancer risk have shown mixed results. In the study published in the Journal of American Medical Association Dermatology, the researchers analysed data from two long-term observational studies in which 121,700 US women were followed from 1984 to 2012 and 51,529 US men from 1986 to 2012.

The research team looked at the diet and skin cancer results of the participants. Between the two studies, around 123,000 participants were white (and thus had a significant risk of developing skin cancer), had no prior history of cancer and completed the dietary reports multiple times.

A total of 3,978 cases of squamous cell carcinoma were reported and verified within the 24 to 26 year follow-up periods. Participants’ hair colour, the number of severe sunburns they had received in their lifetime and any family history of skin cancer were also taken into account.

After grouping the participants into five categories by their Vitamin A intake levels, the researchers found that people in the category with the highest average daily total Vitamin A intake were 17 per cent less likely to get skin cancer than those in the category with the lowest total Vitamin A intake.

The team also found that the majority of Vitamin A came from the participants’ diets, particularly from fruits and vegetables, rather than from animal-based foods or vitamin supplements. (IANS)

World’s Smallest Wearable Can Help in Preventing Skin Cancer

Scientists have developed the world’s smallest wearable, battery-free device that can warn people of overexposure to ultraviolet rays (UV) — a leading factor for developing skin cancer.

Currently, people do not know how much UV light they are actually getting. The rugged and waterproof device interacts wirelessly with the phone and helps maintain an awareness and for skin cancer survivors.

Smaller than an M&M (colourful button-shaped chocolates) and thinner than a credit card, the device can optimise treatment of neonatal jaundice, skin diseases, seasonal affective disorder and reduce risk of sunburns and skin cancer.

Users can glue the device on to their hats, clip it to sunglasses or stick it on their nail and can simultaneously record up to three separate wavelengths of light.

It is always on yet never needs to be recharged.

“There is a critical need for technologies that can accurately measure and promote safe UV exposure at a personalised level in natural environments,” said Steve Xu, from Northwestern University in the US.

“We hope people with information about their UV exposure will develop healthier habits when out in the sun,” said Xu.

There are no switches or interfaces to wear out, and it is completely sealed in a thin layer of transparent plastic, the researchers stated, in the paper published in the journal Science Translational Medicine.

Participants who mounted device on themselves recorded multiple forms of light exposure during outdoor activities, even in the water.

The findings showed that it monitored therapeutic UV light in clinical phototherapy booths for psoriasis and atopic dermatitis (immune diseases) as well as blue light phototherapy for newborns with jaundice in the neonatal intensive care unit.

It also demonstrated the ability to measure white light exposure for seasonal depression, a mood disorder characterised by depression that occurs at the same time every year. (IANS)
