Genetics and Esophageal Cancer
Esophageal cancer can be influenced by certain genetic mutations. Two examples of these mutations are Bloom’s syndrome, which is caused by a mutation in the BLM gene, and Howel-Evan’s syndrome, which is caused by mutations in the RHBDF2 gene. Furthermore, lifestyle choices such as tobacco or alcohol use can also lead to changes in a person’s genetic code, increasing their susceptibility to esophageal cancer.
The Significance of the Microbiome in Health
The collection of microorganisms residing in the mouth is commonly referred to as the oral microbiota. Within these microorganisms lies the microbiome, which encompasses the genes contained within these microbes. Recent scientific studies have revealed a potential connection between imbalances in the oral microbiome, specifically related to periodontal disease, and the development of certain types of cancer. For instance, a study conducted on esophageal cancer patients found that the presence of the bacteria responsible for periodontal disease was associated with a lower survival rate among these individuals. Additionally, other research has indicated that analyzing the human microbiome could potentially serve as a means of identifying individuals at a higher risk of developing cancer.
