One of the compounds in green tea may stay the advance of prostate cancer. Researchers examining Polyphenon E found that it could lower the concentrations of at least three biomarkers that indicate the onset of cancer. Patients took capsules of Polyphenon E equivalent to 12 cups of green tea for 34 days. Afterward, most patients showed significantly decreased levels of the cancer biomarkers—some as much as 30%, the BBC reports.
"We think that the use of tea polyphenols alone or in combination with other compounds currently used for cancer therapy should be explored as an approach to prevent cancer progression and recurrence," says the lead researcher.
