Scientists believe that Oolong tea extract has "great potential" in preventing bad cancer.
Laboratory tests have shown that Chinese tea, used for centuries for its supposed health benefits, stopped the growth of bad cancer cells
The researchers discovered that the extract hindered the DNA of cancer cells and inhibited the growth and progression of tumors.
Green tea has shown a similar promise, the scientists said. However, black tea and black tea have little effect on cells.
Scientists from St. Louis University, Missouri, also badyzed bad cancer rates and deaths from the disease in China.
Their badysis revealed that areas where oolong tea consumption was high generally had lower rates of illness.
The team now says that tea offers a nontoxic approach to bad cancer prevention that one in eight women will develop during her lifetime.
The researchers, led by Dr. Chunfa Huang, examined the effect of oolong tea extract on six bad cancer cell lines.
Cancer cell lines are used in research and are cancer cells that continue to divide and grow over time, under certain conditions, in the laboratory.
The team tested two positive and negative lines, one HER2-positive line and three triple-negative cell lines.
Green tea and oolong extracts banned the growth of bad cancer cells in all six bad cancer cell lines.
While cells treated with black and black tea extracts showed no effect or very low.
The team said, "Based on our findings, oolong tea, just like green tea, plays a role in inhibiting cancer cell growth, proliferation, and progression." bad.
"Oolong tea, like green tea, can induce lesions and cleavage of DNA, play an inhibitory role in the growth, proliferation and tumorigenesis of bad cancer cells, and [it has] chemopreventive potential against bad cancer ".
Green tea has shown anti-cancer benefits in previous studies, but oolong tea has been the subject of less research.
World production of tea represents only 2% of oolong tea, compared to about 78% of black tea and 20% of green tea, the authors said.
It is mainly produced in China, where people use it for supposed medicinal purposes since a historical period.
Therefore, scientists also reviewed the 2014 data from the annual cancer registry report of China and Fujian Province.
They found that the incidence of bad cancer in Fujian Province was 35% lower than the national average.
Those who drank the most oolong tea had a 25% lower incidence than the average Fujian and 50% lower than the national average.
They also appeared to have a lower mortality rate – the mortality rate of large consumers of oolong tea in Fiji was 68% lower than the national average, according to the findings of the journal Anticancer Research.
Although the results are significant, additional research is needed, said the authors.
"It is clear that additional studies are needed," said Dr. Huang. "The decline in incidence and mortality in regions with high consumption of oolong tea indicates that oolong tea has significant potential for its anticancer properties."
Breast cancer has been diagnosed in more than 250,000 women in the United States in 2018 and approximately 41,000 die each year.
Although survival rates have improved – doubling over the past 40 years in the UK – the treatment is grueling.
A bad cancer survey found that 26% of women found that the end of treatment was the most difficult part of bad cancer.
