Can Antibiotics Increase Caner Risk? Dr. David Samadi Explains

Researchers have concluded, prolonged use of antibiotics increases the risk of polyps in the intestine, and in some cases may evolve into a malignant form of colorectal cancer. In a published article last month, Dr. David Samadi discussed antibiotic use and the impact of good bacteria in our colon.

Researchers from Massachusetts General Hospital in Boston analyzed the data obtained from a group of 16,600 women. The researchers analyzed the association between the appearance of polyps (diagnosed in 1,195 women) and a prolonged use of antibiotics. Those who took antibiotics for more than 2 months, between 20 and 39 years, have a 36 percent greater risk of developing a colonectal benign glandular tumor, than those who did not make prolonged use in those same years. For those between 40 and 59 years, the risks increase to 69 percent.

Antibiotics offer a robust defense against the spread of bacteria, but according to Dr. David Samadi, sometimes they can cause quite a few side effects, such as diarrhea, alteration of intestinal bacterial flora, and damage to the liver.

Dr. Samadi points out, while this medicine is important, antibiotics also eliminate the healthy bacteria necessary for good digestive health. Studies have shown that probiotics Lactobacilli and Saccharomyces have been particularly effective in countering the side effects of antibiotics. In addition to improving intestinal health after taking antibiotics, some studies have concluded that fermented foods can also be useful during treatment with an antibiotic.

Protecting Gut Bacteria

Dietary fibers are mainly carbohydrates that can not be digested by the human body, but can instead be digested by intestinal bacteria, and in this way the fibers help to stimulate the growth and spread of beneficial microorganisms. As a result, dietary fiber helps restore proper bacterial flora after antibiotic treatment.

An advocate of healthy nutrition, Dr. Samadi suggests foods with a high fiber content, like whole grains, wholemeal bread, brown rice, nuts and other nuts, seeds, legumes, broccoli, fruit and vegetables. Research has shown that foods containing dietary fiber are not only able to stimulate the growth of healthy bacteria in the intestine, but can also reduce the growth of certain harmful bacteria.

With more than 58 peer-reviewed medical papers, consecutive awards for Best Doctor, Top Doctor, and Patient’s Choice, Dr. David Samadi has received international attention for his work in the treatment of urilogical diseases.

He was born in Iran, immigrated to the UK, and then to New York. Dr. Samadi earned his medical degree from Stony Brook University; completed his residency at Montifiore Hospital, and an oncology fellowship at Memorial Sloan Kettering Cancer Center.
