Breast cancer is the most common tumor in women and was diagnosed in more than 184,000 U. S. patients in 2008, according to estimates from the National Cancer Institute.

Recent study revealed that daily intake of mushroom can help in fighting cancer. Intake of green tea along with mushroom can increase the protection against breast cancer.

Research team at the University of Western Australia in Perth analyzed data collected from 2,000 Chinese women. Approximately half of the study subjects had suffered breast cancer.

Data analysis revealed that intake of at least a third of an ounce of fresh mushrooms every day lowered the risk of tumors by 64 per cent. Intake of dried mushrooms reduced the risk by half. Intake of mushroom and green tea can reduced the risk by 90 percent.

Some studies have shown that mushrooms act in a similar way to breast cancer drugs called aromatose inhibitors, which blocks the body's production of the hormone oestrogen, which can encourage the development of cancer.
