Global cancer cases in people under the age of 50 have seen a staggering 79 percent increase between 1990 and 2019, with colorectal cancer rates expected to double in the under-40 age group by 2030. Lifestyle factors such as highly processed diets and heavy alcohol use are being blamed for the rise in cancer cases among younger generations.
Researchers have identified the bacteria Fusobacterium nucleatum as a key player in various cancers, including breast, colorectal, and head and neck cancers. Additionally, factors like vaping, poor oral hygiene, high consumption of processed meat, and excessive alcohol intake are driving up cancer rates in the young.
Furthermore, the sexually transmitted human papillomavirus (HPV) has been linked to mouth cancer in individuals aged 40-49. Ultra-processed foods and certain bacteria have been found to contribute to the development and progression of cancer, particularly in the bowel.
Scientists are exploring the potential of using phage therapy and targeted vaccines as treatments for cancers driven by problematic bacteria. Additionally, emerging connections between microbes and early-onset cancers could lead to the development of new, more targeted treatments.
In the future, researchers believe that the microbial composition of a tumor could potentially be utilized to make more informed treatment decisions for aggressive cancers. This new understanding of the role of bacteria in cancer development could revolutionize the way cancers are treated and pave the way for more effective therapies.
