Excessive consumption of antibiotics would increase the risk of early-onset colorectal cancer, also known as colon cancer, by 49%, according to a study led by British researchers and presented at the World Congress on Gastrointestinal Cancer.
According to the research, which was based on a series of case-control analyzes using data from primary care in Scotland, antibiotics are a cause of the appearance of this type of cancer, in addition to the already known factors such as obesity, poor diet, hereditary role and excessive consumption of alcohol and tobacco.
Colon cancer develops in the large intestine, made up of the colon and rectum. In the region of the Americas alone, 240.000 new cases occur each year, of which some 96.000 patients die, according to data from the Pan American Health Organization (PAHO).
The researchers believe that the problem lies with the microbita, a set of bacteria that colonize parts of the body, including the digestive system. Antibiotics could unbalance and damage the digestive microecosystems through long term.
Last year, a group of researchers from the University of Umeå, Sweden, also determined that there is a link between colon cancer and excessive consumption of antibiotics, after studying 40.000 cancer cases.
The researchers believe that the impact of antibiotics on the gut microbiome is behind the increased risk of cancer.
Drug achieves remission of colon cancer
A trial of an experimental therapy in the United States achieved complete remission of colon cancer in all his patients, a fact classified as unheard of by researchers and doctors, according to an article published in June in the New England Journal of Medicine.
In the tests, a drug called Dostarlimab was applied every three weeks for six months to 12 patients, achieving remission of the cancer.
The drug exposes the cancer cells, allowing the immune system to identify and destroy them.
