Researchers have found that the daily consumption of coffee after breast cancer diagnosis may reduce the risk of developing it again.

The study was conducted at Lund University in Sweden and saw that there was a large decrease in the risk of breast cancer relapse, by almost half, in patients who took an anti-cancer drug and drank two cups or more of coffee a day. 

They believe that coffee enhances Tamoxifen's ability to prevent estrogen-fed cancer from growing.

In the study, they followed over 600 breast cancer patients from southern Sweden for five years. Three hundred of those patients took Tamoxifen.

The majority of breast cancer tumors, about 75 percent, rely on estrogen to grow.

If a cancer has receptors for estrogen, it is called ER+, or estrogen-receptor-positive. This means that they are similar to breast cells in that they respond to estrogen signals. Anti-hormonal treatment, like Tamoxifen, disables cancer's ability to code by deactivating the receptor sites.

Caffeine, researchers believe, helps the drug be more effective.

Along with helping prevent a breast cancer relapse, coffee has also been found to lower the risk of cardiovascular disease by 38 percent in men and 22 percent in women.

A study from University of Eastern Finland's School of Medicine found that short-term stimulating effects on the central nervous system from caffeine contributed to the inhibition of cognitive decline. They discovered that drinking three to five cups a day decreased participants' risk for developing Alzheimer's.

It also has been found to reduce risks for type-2 diabetes and prostate cancer.
