Coffee and tea possess antioxidant, anticancer, and anti-inflammatory properties. However, the association between coffee or tea consumption and the risk of head and neck cancer (HNC) remains uncertain. A study has investigated this association by analyzing 14 studies involving 9,548 HNC cases and 15,738 controls. The study found that consuming over four cups of caffeinated coffee daily was linked to a lower risk of HNC, including oral cavity and oropharyngeal cancers while drinking three to four cups reduced hypopharyngeal cancer risk.
Similarly, drinking zero to one cup of decaffeinated coffee was associated with reduced oral cavity cancer risk. On the other hand, tea consumption showed a protective effect against hypopharyngeal cancer, with consuming over zero to one cup daily lowering HNC risk. However, drinking more than one cup of tea daily was associated with an increased risk of…
