There are many rumors circulating online about the connection between microwaves and cancer risk. What is the truth behind this? Let’s take a look at what reputable health organizations around the world have to say.
Microwaves have been an essential household appliance for decades, allowing you to cook and reheat food very quickly. However, while preparing food, many people may wonder if any radiation could escape from the microwave and potentially cause harm.
As a result, numerous rumors about microwaves and health risks have emerged online, with the most notable being the claim that “Standing too close to a running microwave may increase the risk of developing cancer.”
So, what is the reality of this rumor?
Microwaves help you cook or reheat food in just a few minutes.
Microwaves heat food by using microwave radiation. According to the U.S. Food and Drug Administration (FDA), microwave radiation is a type of electromagnetic radiation (energy waves that travel through space). Electromagnetic radiation comes in various forms, including radio waves, visible light, X-rays, and gamma rays.
The FDA states that microwave and radio waves are classified as “non-ionizing radiation,” meaning they do not have enough energy to knock electrons out of atoms. Therefore, microwaves do not damage the DNA inside cells, according to the American Cancer Society.
In contrast, X-rays and gamma rays are classified as “ionizing radiation,” which have enough energy to remove electrons from atoms and can damage cells and DNA.
Harvard T.H. Chan School of Public Health, part of Harvard University, explains similarly. According to the school’s official website, the rumor that “standing near a running microwave causes cancer” is completely false.
“Microwaves are designed so that microwave radiation is contained within the appliance. The microwave only generates waves when the door is closed and the unit is turned on,” Harvard School of Public Health explains.
When a microwave is in good condition and used according to guidelines, there is no evidence to suggest that they pose any danger to human health.
“People should ensure that their microwaves are in good working order. You should replace your microwave whenever it is damaged to prevent any risks,” the Harvard School of Public Health further advises.
In summary, the Harvard School of Public Health confirms that using a microwave poses no risks as long as the appliance is in good condition.
