Breast Cancer And Working Outdoors

Individuals who work out outdoors are exposed to more sunshine, which increases their vitamin D levels and can protect against the disease, according to the researchers.

Vitamin D is well known for its function in bone and musculoskeletal wellbeing, but it can also play other functions, such as aiding in preventing infection and cancer. UVB sunshine is the main source of vitamin D. However, worries about the possibility of skin cancer and the increased usage of machines for both work and recreation have reduced the amount of time people spend outside.

Studies report an increasing prevalence of breast cancer in the second half of the twentieth century. This rise led to the speculation that it may be due to vitamin D deficiency.

Previous literature suggests that higher levels of vitamin D in the blood could be linked to a reduced risk of breast cancer, although the data is mixed.

Most experiments have focused on short-term measurements of vitamin D levels rather than long-term levels. Sunlight exposure can be used as a proxy for long-term vitamin D levels. Since the body produces vitamin D mostly during the working day (between 10:00 and 15:00), outdoor employees are subject to much higher levels than people who work indoors.

An experiment was conducted in which the researchers used the Danish Cancer Registry to identify 38,375 women under the age of 70 who had been diagnosed with primary breast cancer. 

In the course of this study, they compared them to five women born in the same year and chosen at random from the Danish Civil Registration System.

The history of each worker was found to provide a proper understanding. So, The full work history of each worker was obtained from Danish pension fund documents, and a work exposure index was used to determine her occupational exposure to sunlight. After accounting for potential factors affecting reproductive history, no connection was found between occupational exposure to sunlight and overall breast cancer risk. 

It was also found that long-term workplace use, on the other hand, was linked to a lower risk of breast cancer after the age of 50.  During the study, it was noted that, In these women, workplace exposure for 20 years or longer was associated with a 17% lower risk of breast cancer detection, whereas the highest degree of average exposure was associated with an 11% lower risk.

Since this study was an empirical study, predicting the source might turn out to be pretty difficult. Furthermore, there was no detail on dietary vitamin D consumption or usage of vitamin D supplements, which may not be important because other studies have shown that indoor workers have slightly lower serum vitamin D levels than outdoor workers, according to the researchers.

Sunlight emission estimates, when calculated, were still found to be imprecise. Moreover, leisure time sunshine penetration and potentially influential lifestyle considerations such as Pill use, hormone replacement therapy, and alcohol, as well as obesity and leisure time physical activity, were not taken into account.

Nonetheless, the researchers reach the following conclusion: “This analysis found a connection between long-term occupational [sunlight] exposure and late-onset breast cancer. This observation necessitates additional investigation in prospective occupational research.”

More research needs to shed light on this niche. This study has proved something quite solid to build upon, which might further help us understand the factors responsible for minimizing the risk of breast cancer in women.

Understanding that exposure to sunlight is also necessary is the key fundamental. But the risk of skin cancer also poses a threat. Through research, we might be able to devise methods in order to have more control over the situation.
