Gut Microbiome Plays Crucial Role in Cancer Risk, Experts Warn

According to medical experts, the gut microbiome, the trillions of bacteria living in the human gut, plays a crucial role in shaping cancer risk. As of November 10th, 2025, research has shown that a healthy, diverse gut microbiome can help the immune system mount a stronger response against cancer cells, while an imbalanced gut microbiome, known as dysbiosis, has been linked to the development of various diseases, including cancer.

The experts explain that a high-fiber diet, Mediterranean diet, and plant-based diet can promote the growth of beneficial gut bacteria and reduce the risk of cancer. Conversely, a high-fat diet, processed foods, and obesity can lead to inflammation in the gut, creating a tumor-promoting environment. Additionally, inadequate sleep and physical activity have also been associated with an increased cancer risk.

Ongoing research is exploring the use of probiotics and fecal transplants to enhance the effectiveness of cancer treatments, such as immunotherapy. Experts emphasize that cancer is a lifestyle disease, and adopting healthy habits, including a balanced diet, regular exercise, and proper sleep, can significantly reduce the risk of developing cancer.
