Alcohol, shampoo, and even car exhaust can cause malignant tumors, since all of these substances contain dangerous substances..

Alcohol abuse can lead to tumors, as science has long known. However, until recently, scientists did not know which component of alcoholic beverages increases the risk of cancer.. This question was answered by researchers from the University of Cambridge, and their results also explain why car exhaust, cigarette smoke, furniture and even shampoo lead to cancer..

It's all about the chemicals called aldehydes that are found in all these substances.. The human body itself produces aldehydes in small quantities.. However, they are very abundant in the environment, especially in car exhaust, tobacco, furniture and cosmetics..

In addition, the body also breaks down alcohol that enters the stomach into acetaldehyde, which is also a dangerous component.. Researchers have shown that aldehydes disrupt the way human DNA vulnerabilities are repaired. Humans have two copies of the BRCA2 gene, which produce a protein that helps repair DNA.. This damage, which develops during cell division, can cause tumors if it is not corrected in time..

A new study shows that aldehydes cause a drop in the level of the BRCA2 protein in cells, which impairs their ability to heal.. Approximately one in 100 people have a genetic vulnerability in the BRCA2 gene, which makes it produce less of the right protein. This already places him at particular risk for ovarian, prostate and pancreatic cancers.. Acetaldehyde is normally broken down in the body, but the 500 million people with a vulnerable gene called ALDH2 simply don't.. They accumulate aldehyde, which increases the risk of cancer, regardless of whether they have inherited a defective copy of BRCA2 or not..
