Swedish and British scientists have released a study showing that drinking at least two cups of coffee a day may reduce the risk of breast cancer recurrence. The related paper is published in Clinical Cancer Research (Clinical Cancer Research).

The researchers tracked the treatment, lifestyle and daily coffee consumption of 1090 breast cancer patients in Sweden and found that among the 1090 breast cancer patients treated with Tamoxifen, those who drank two to five cups of coffee a day had a half lower risk of recurrence than those who did not drink coffee or drank less than two cups of coffee a day.

The researchers believe that the reason why coffee can play this role is that caffeine and caffeic acid in coffee can inhibit cell division and accelerate cancer cell death, which will become more obvious when combined with tamoxifen. However, the researchers also pointed out that drinking at least two cups of coffee a day can enhance the effectiveness of the treatment, but only if the treatment is maintained.

In fact, several previous studies have shown that drinking coffee can help reduce the risk of cancer. Drinking a moderate amount of coffee may reduce the risk of cancer such as oral cancer, bladder cancer, colon cancer, esophageal cancer and endometrial cancer.

Breast cancer is one of the most common cancers for women today. According to data released by the World Health Organization, there were 1.7 million new cases of breast cancer worldwide in 2012 alone, accounting for nearly 12% of all new cancer cases that year.
