Consuming two or more cups of coffee on daily basis could decrease the risk of breast cancer recurring in women taking the drug Tamoxifen, a study at Lund University in Sweden has suggested.
During the study, patients who took the drug, along with two or more cups of coffee daily, were found to have less than half the rate of cancer recurrence in comparision to those who did not drink coffee along with Tamoxifen.
The team observed over 600 patients suffering with breast cancer from the southern Sweden for an average of five years, out of which 300 took Tamoxifen. Tamoxifen is a common hormone therapy suggested after breast cancer surgery, which is known to reduce the risk of new tumours by blocking oestrogen receptors.
However, it is still ambiguous as how coffee interacts with the treatment.
"One theory we are working with is that coffee 'activates' Tamoxifen and makes it more efficient", said Maria Simonsson, doctoral student in Oncology at Lund University.
The Lund University researchers have earlier related coffee consumption to a decreased risk of developing certain types of breast cancer.
Caffeine, a constituent found in coffee has also been shown to probihit the growth of cancer cells. The latest observational study involving coffee's role in cancer prevention and treatment underlines the need for more research, the team noted.
