A person’s occupation, or what kind of work they do, can bring a person money, satisfaction and even fame. But occupations can also be dangerous and make people sick. Some dangerous jobs are easy to recognize, like being a firefighter or a soldier. However, there are occupations that are dangerous because over time they can give you diseases like cancer.
You might think working on an airplane would be dangerous because of airplane crashes, but the real danger is something we can’t see. Flight crews are exposed to high amounts of radiation because they are so high up in the atmosphere. A new study of 5,366 flight attendants from the US has found that they have higher rates of breast and skin cancer than people who work on the ground.
Something that gives you cancer is called a carcinogen. Something in your workplace that can give you cancer is called an occupational carcinogen. There are many types of carcinogens, such as viruses, chemicals, alcohol and even radiation from the sun. If there are many people who smoke in your workplace, or if you spend a lot of time outside, you are exposed to more of those carcinogens.
致癌物質英文稱作carcinogen，職場裡的致癌物質就叫occupational carcinogen。致癌物質有許多種，例如病毒、化學物質、酒精、太陽輻射等。職場上，如果常吸二手菸， 或在戶外長時間在陽光下曝晒，這些都表示你已曝露在大量的致癌物質中。
In order to avoid getting cancer, we must try to keep our exposure to carcinogens down. There are three main ways that we get exposed to carcinogens: we could touch them, breathe them in, or swallow them. We may not touch the sun, but solar radiation touches our skin. We might breathe in smoke, dust or other gases. Last, we might swallow contaminated food or drink.
Sometimes something as simple as not getting a good night’s sleep can up your chances of getting sick. Jobs that require people to work strange hours, like flight crews or night shift workers, are hard on the body. Our bodies have a rhythm that follows sunlight called the circadian rhythm. Over time, disrupting this rhythm increases your chances of getting a disease, like cardiovascular disease or cancer.
