It is official! Your cup of coffee has the potential to cut risk of breast cancer recurrence, claims a new study led by Lund University.
While previous studies have shown that coffee helps to protect against breast cancer, a new study has confirmed that coffee inhibits the growth of tumors and reduces the risk of recurrence in women who have been diagnosed with breast cancer and treated with the drug tamoxifen.
Researchers Ann Rosendahl and Helena Jernstrom said that the study showed that among the over 500 women treated with tamoxifen, those who had drunk at least two cups of coffee a day had only half the risk of recurrence of those who drank less coffee or none at all.
It also showed that those who drank at least two cups of coffee a day had smaller tumors and a lower proportion of hormone-dependent tumors.
In the cell study, the researchers looked more closely at two substances that usually occur in the coffee drunk in Sweden - caffeine and caffeic acid.
They added that breast cancer cells reacted to these substances, especially caffeine, with reduced cell division and increased cell death, especially in combination with tamoxifen, and it showed that these substances had an effect on the breast cancer cells and turned off signaling pathways that the cancer cells required to grow.
The researchers have demonstrated both in breast cancer patients and at cell level that coffee appears to reinforce the effect of treatment with tamoxifen, but emphasize the importance of taking prescribed medication.
