Breast cancer is a health issue that receives a considerable amount of attention nowadays, and there’s a good reason for that. The National Cancer Institute estimates that, just in the United States, more than 190,000 women were afflicted with breast cancer in 2009. More than 40,000 of those women were expected to die from the disease.
While it’s never a good idea to overstate the potential health benefits of a food or beverage, there are several studies that show that tea can have some useful effects when it comes to breast cancer. A study by researchers at the University of Mississippi found that epigallocatechin-3-gallate (EGCG) “significantly inhibits breast tumor growth in female mice.” EGCG is an antioxidant that exists in high concentrations in green tea.
Another study, results of which appeared in the Journal of Cancer Biology and Therapy, came to a similar conclusion. Researchers found that green tea had an antitumor effect on breast cancer cells. They also mentioned several other studies that discovered that the risk of breast cancer was reduced in Asian countries where green tea consumption is typically higher.
Additional research supports the notion that tea drinking among Asians tends to result in a lower risk for breast cancer. In 2004 and 2005 Chinese and Australian researchers tested female subjects, aged 20-87, in southeast China. They found that “that regular consumption of green tea can protect against breast cancer.” For more info about a similar study, look here.
“A meta-analysis of epidemiological studies” by researchers in the United States also found that green tea consumption might lower the risk of breast cancer. They found, however, “a modest increase in risk associated with black tea intake.” A study conducted by researchers at the Harvard School of Public Health found no link between coffee and tea consumption and the risk of breast cancer.
