LONDON: Researchers have found that women who work night shifts for more than 30 years may be at a higher risk of breast cancer than other women.
The study, published in the British Medical Journal (BMJ), was done by researchers in Canada. They analyzed the careers of 1,134 women with breast cancer and 1,179 women without the disease.
The women, all of the same age, were questioned about their shift work patterns throughout their employment history, and hospital records were used to determine their tumor type.
Around 1 in 3 women in both groups of the study had worked night shifts. The research revealed that women who had worked night shifts for up to 14 years or for between 15 and 29 years had no increased risk of developing breast cancer. But the women who had worked night shifts for 30 years or more were twice as likely to develop the disease.
In the study, the researchers suggest that the night-time artificial lighting that shift workers are exposed to could be one factor giving rise to the cancer link.
The researchers believe that long-term exposure to artificial lighting can suppress the production of melatonin.
Melatonin is a natural hormone made by the body’s pineal gland, found in the brain. The pineal gland is inactive during the day. During the night, the gland actively produces melatonin, rising the level of the hormone in the blood and causing a person to feel less alert, encouraging the need for sleep.
Melatonin levels are elevated for around 12 hours throughout the night and reduce to an almost undetectable level during the day. The NSF says it may be that exposure to artificial light during the night inhibits the pineal gland’s production of melatonin.
According to the researchers in the BMJ study, lack of melatonin production can lead to increased production of estrogen in the body, and that this may be a trigger for breast cancer in some women.
The researchers also discuss whether sleep disturbances, upset body rhythms, lack of vitamin D and lifestyle differences also contribute to the increased risk of breast cancer.

Where We Are Going Today: Crozy
Some desserts look heavy before you even take a bite, but that was not the case at Crozy. From the first try, the pastries were airy, fluffy and light, offering a comforting taste without the feeling of consuming overly high-calorie sweets.
The pastries lean toward a fruity and slightly sweet profile, avoiding the common pitfall of being overwhelmed by sugar. The texture is puffy and delicate, and I genuinely loved and savored my first bite.
I opted for the berry filling, though the menu offers a variety of flavors. The balance between the fruitiness and the soft pastry made the experience feel indulgent yet surprisingly light.
The coffee was another highlight. It had a dark, toasted profile with a rich and favorable coffee taste. What stood out most was the savory aftertaste, which lingered pleasantly and paired beautifully with the sweetness of the pastry. Together, the pastry and coffee created a wonderful combination.
Crozy also stands out for its presentation. The packaging is stylish and thoughtfully designed, and the creativity in the flavors reflects a brand that clearly puts effort into both aesthetics and taste.
Boxes are priced between SR95 ($25.30) and SR200, depending on the size and variety of pastries included.
One downside is accessibility. The brand appears to have only one branch located in Dhahrat Al-Laban, meaning you may need to make a dedicated trip if you want to try it. It is also available via delivery apps.
While the pastries themselves are truly impressive, flavorful, light and beautifully presented, service consistency could improve. On one occasion, an order for creme brulee was substituted with pistachio because the original item was unavailable, which was disappointing.
Despite this, Crozy delivers a memorable dessert experience. The flavors are creative, the pastries are deliciously light, and the coffee pairing makes it a place dessert lovers will likely find themselves returning to.
