Men who work day and night are more likely to develop prostate cancer

Lao Cui is 47 years old and works in a factory that produces large devices. The production workshop implements an assembly line operation mode. The workers work in three shifts, and the machines continue to work while people rest. Lao Cui's wife works in the same unit as him. She resigned a few years ago due to poor health and has been at home ever since. Their daughter is in the second year of high school. In order to save money for her daughter to go to college, Lao Cui always works overtime. Sometimes he works two shifts out of three in a day, and often reverses his day and night. His wife feels distressed when she sees this, but there is nothing she can do. All she can do is take care of the housework and make more nutritious meals for Lao Cui. In the past year, Lao Cui always felt that urination was not as comfortable as before, the urine flow became thinner, and he always felt that he could not urinate completely. Lao Cui did not care, thinking that it was caused by his old age and prostate hyperplasia. In the past two months, Lao Cui felt that urination was very difficult, and sometimes there was a noticeable feeling of holding back, but he could not urinate. Moreover, in the afternoon, obvious swelling would appear on his calves.

Lao Cui often works overtime, has a reversed day and night schedule, and leads an irregular life, which disrupts his biological clock and reduces the secretion of melatonin, which inhibits the proliferation of prostate cancer cells. This may explain why men with irregular working hours and reversed day and night schedules are more likely to develop prostate cancer.
