Following on from my research on annual body clocks last week, I came across quite a number of papers associating the season of detection of breast cancer with survival rates. A 7-year study that was published in 1983, looking at ~3000 female patients showed a peak of breast cancer symptoms in Spring, with a corresponding trough in the Autumn [1]. This has been verified in many other studies across the globe, showing tumour growth and aggression is higher in Spring. Larger studies went on to determine a link between the survival rate of cancer patients and the seasons the tumour was detected and treatment began. One study of over a million cancer patients in the UK showed that a patient diagnosed in the Summer or Autumn had a greater chance of survival than if diagnosed in the Winter [2]. A smaller study, under 50 000 women, in Norway also confirmed that a Summer diagnosis increased the chance of survival by 10-15% over a Winter diagnosis [3]. This data was collected between 1964-1992 and looked at the differences in age and the region them women were living. Women under 50 that lived in a region with more sunlight had a better prognosis than those regions with less sunlight. However, although seasonal rhythms were detected, no regional differences were observed, in women over 50. So, can sunlight improve survival rates of breast cancer? Or are there other factors, such as a higher number of infectious diseases around wintertime. There is growing support that vitamin D, a chemical our body makes in response to sunlight, plays a role in survival against cancer [2]. Lab studies have shown that the products our body makes from vitamin D slow down cell growth [4]. Also, seasonality in cancers is more likely to be seen in women than in men, which is consistent with women being frequently reported of having lower vitamin D levels in winter. One way to look at the link between vitamin D and cancer would be to look at cultures that eat more dietary vitamin D, or have a diet that changes the rate of vitamin D production. Drug companies are also looking into producing the products of vitamin D that may help cancer patients. The link between vitamin D products and cancer survival still needs to be fully addressed. Until then, the advice is for women to check themselves monthly, and go out and enjoy the summer sunshine. (Don't forget the sunscreen!) Lim, R. Roychoudhuri, J. Peto, G. Schwartz, P. Baade, and H.

Sunce promiče cjelokupno zdravlje, sprječava rak, te pruža osjećaj sreće. Nedavno istraživanje pokazala je da vitamin D, koji se stvara u tijelu nakon izlaganja suncu, štiti od kolorektalnog, raka dojke i raka prostate. O današnje vrijeme rak je jedan od vodećih zdravstvenih problema koji uzrokuju smrt miliona širom svijeta. Veza između vitamina D i raka pronađena je na Sveučilištu u Kaliforniji. Više ispitivanja su potvrdila moć vitamina D protiv raka, onemogućavanjem rasta stanica raka, potičući stanične diferencijacije, sprečavanje proizvodnje krvnih žila u tumorima te inducira apoptozu. Kombinacija vitamina D i kalcija smanjuje rizik od svih vrsta raka u žena u postmenopauzi za nevjerojatnih 77%. A trebali biste se konsultovati sa iskusnim liječnikom, o pravilnom doziranju vitamina D za liječenje ozbiljnih zdravstvenih problema.
