Accordingly, brushing and flossing regularly can help reduce the risk of head and neck cancer by up to 50%, including cancers of the oral cavity, nose, pharynx, larynx, salivary glands and thyroid, according to the medical website Medical Express.
Good oral care can reduce the risk of head and neck cancer by up to 50%
Scientists at New York University Langone School of Medicine (USA) and the school's Perlmutter Cancer Center analyzed the diet, lifestyle and medical history of 159,840 participants.
To determine the correlation between cancer risk and certain types of bacteria in the mouth, the authors tested the bacteria in saliva samples from participants. They then followed the participants for about 10 to 15 years.
After 15 years, 236 people developed head and neck cancer.
Researchers compared the oral bacteria of cancer patients with those of 458 people without cancer.
The results found that there are 13 species of bacteria in the mouth that increase the risk of cancer.
Head and neck cancers include cancers of the oral cavity, nose, pharynx, larynx, salivary glands, and thyroid gland.
These bacteria are linked to a 30% higher risk of developing head and neck cancer. When combined with five bacteria commonly associated with gum disease, the total risk increases to 50%, according to Medical Express.
The researchers claim to have identified the main types of bacteria that can cause cancer, and will next plan to explore their mechanisms of action and how best to intervene.
In terms of intervention, brushing and flossing are the best defenses against harmful bacteria.
The study’s author, Professor Richard Hayes, of New York University, said: “The results of the study provide another reason to practice good oral hygiene. Brushing and flossing not only help prevent periodontal disease but also protect against head and neck cancers.
