Oolong tea extract has 'great potential' to prevent breast cancer

U.S. scientists believe that oolong tea extract has "great potential" in preventing breast cancer.
chinese tea, which has been considered healthy for centuries, has stopped breast cancer cells from growing, according to laboratory tests.
researchers found that the extract blocked the DNA of cancer cells and inhibited the growth and progression of tumors.
say green tea has a similar effect.
, however, black tea and black tea have little effect on cells.
University in St. Louis, Missouri, also analyzed breast cancer and breast cancer mortality rates in China.
their analysis found that in areas where oolong tea consumption is high, the risk of disease is usually low.
the 2014 annual report of the Cancer Registry of China and Fujian Province, it was found that the incidence of breast cancer in Fujian Province was 35% lower than the national average. Among the people who drank the most oolong tea, the incidence of breast cancer was 25% lower than the Fujian average and 50% lower than the national average.
the team said oolong tea could be a non-toxic way to prevent breast cancer.
the study, published in the journal Cancer Research, people who regularly drank oolong tea also appeared to have lower mortality rates, and those who drank oolong tea regularly in Fujian also appeared to have a 68 percent lower mortality rate than the national average.
, led by Dr. Chunfa Huang of st. Louis University School of Medicine, tested the effects of oolong tea extract on six breast cancer cell lineages.
results, oolong tea, like green tea, plays an important role in inhibiting breast cancer cell growth, proliferation and tumor progression.
all of them can induce DNA damage and division, inhibit the growth, proliferation and tumor occurrence of breast cancer cells, and are a promising anti-breast cancer drug.
processed with black tea and black tea extract in the same time, had little or no effect.
