Sumary of Breast cancer: Popular drug known to disrupt microbiome could be increasing your risk:
- Breast cancer is the most common type of cancer to be diagnosed in the UK, but it’s not always easy to know if you’re at risk.
- A possible link between antibiotic use and an increased rate of breast cancer growth has been identified by scientists.
- Researchers from Quadram Institute in Norwich and the University of East Anglia studies a total of five different antibiotics including the common cefalexin and investigated how it may impact breast cancer cells.
- It was noted how the antibiotics disrupted the healthy balance of bacteria in the gut which impacted tumours.
- Researchers discovered that treating mice with broad-spectrum antibiotics made their breast cancer tumours grow more quickly.
- An increase in the size of secondary tumours that grew in other organs when the cancer spread was also noted.
- Dr Simon Vincent, of Breast Cancer Now said: “While the link between antibiotics and breast cancer growth may sound alarming, we want to remind everyone affected that this is early-stage research that has currently only been tested in mice.
- ‘“Excitingly, this has already highlighted that by targeting mast cells we could potentially halt antibiotic-induced breast cancer growth.
