Stress, Aluminium, Mobile Phone Radiation? The biggest cancer myths facts check
Cell phone radiation is carcinogenic, and aluminum Deodorants. Or is it not? Many common cancer myths are based on few and small studies and is not scientifically proven. FOCUS Online explains what scientists know currently really certain cancer risks.
Thesis 1: Aluminium in Deodorants causes breast cancer.
Deodorants with aluminum salts have got a few years ago, in disrepute, because they are intended to lead women to breast cancer. Many manufacturers renounced on aluminum and signed on its products for extra than "aluminiumfrei" from. However, the study location is clearly not enough to demonise aluminum as Cancer-causing agents. Although there are studies that show a connection, but as well what, can’t find a connection.
"Here the data is mixed and part of widersprüchlich", summarizes the Federal Institute for risk assessment. The German cancer information service stresses that The majority of scientists have, as yet, no evidence that aluminum increase the risk of cancer.
Thesis 2: cell phone cancer rays are causing.
That’s not true, probably. Of an average cell phone use no increased risk of Brain tumors. This is the result of the to date largest study on the use of mobile phones and associated cancer risks: the Interphone study, at least. It includes data from 13 countries, including some 2,700 people with brain tumors who were asked about their mobile phone use. For comparison, the researchers used data from nearly 7700 healthy people.
Nevertheless, the world health organization (WHO) classified radiation mobile phone as a "may krebserregend" a. The cancer information service, explains the decision by the WHO as follows: To refer to a few studies that have provided evidence that "A lot of callers, the very early and very long phone nutzten", there is an increased risk of cancer.
Also here, further studies are still necessary. So the experts point about that old investigation related in part to mobile phone users, which had already phoned in the early 80s, mobile with devices and in networks with much stronger radiation than is the case today.
Hypothesis 3: Stress leads to cancer.
Stress is clearly unhealthy. So stressed-out people suffer from chronic more likely to have a cardiovascular disease. However, Stress can also cause cancer? Here’s the science of ghosts. Some researchers suggest that certain stress hormones could contribute to the emergence of a tumor. Others believe that Stress could weaken the immune system and in this way, particularly in relation to cancer. Others see no connection.
The German cancer information service, explains the Dilemma: The relationship between immune system and cancer development are so complex, "that there is a clear relationship, despite many years of research until today ist" to prove;. Secured documents there is, therefore, so far, for any of the positions.
Hypothesis 4: women with large Breasts have an increased risk for breast cancer.
That’s not true. The size of the breast says according to the current state of the science, nothing about the risk of developing breast cancer. A disadvantage of women with a large bust, however: your Breasts are harder to examine. Especially small nodules are not so easy to locate. In addition, the tissue of large Breasts appears in a mammogram poet. Changes are discovered, sometimes only a little later, explains cancer expert Jens Siveke to FOCUS Online.
Hypothesis 5: milk products trigger cancer.
Milk has long been regarded as a healthy, now, more and more milk opponents and scientists. In terms of the risk of cancer of the milk is still safe, says the German cancer information service – provided you drink it in normal amounts. The German society for nutrition recommends approximately a quarter of a liter of low fat milk per day.
So far, there is too little data to provide a secure connection between milk and cancer, according to the experts. Therefore, the Association enjoy the some studies with caution: time study by the American cancer society came about a long to the conclusion that an increase in milk could protect consumption against colorectal cancer. Another study, by contrast, brings a high intake of milk or milk products with an increased risk for prostate cancer.
Thesis 6: the coffee is carcinogenic.
The International Agency for research on cancer was 2016 all-clear signal 23 to a working group of scientists involved had been able to discover any cancer-causing effect of coffee. Previously, several studies had suggested that coffee and tea drinkers have an increased risk for esophageal cancer. Meanwhile, researchers suspect, however, that the less had to do with the drink but with a much too high temperature.
The cancer information service, sums it up: "As long as you don’t drink is coffee boiling, it is not harmful and may even be a downright healthy beverage."
