The findings of a new study have now revealed that drinking just 2 cups of coffee a day could reduce the growth of breast cancer tumors, and also reduce recurrence in women who are already undergoing the treatment.
The researchers considered 1090 breast cancer patients for the study and combined the information about their lifestyle and clinical data.
“The study shows that among the over 500 women treated with (the drug) 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,” the researchers explained.
“The study also shows that those who drank at least two cups of coffee a day had smaller tumours and a lower proportion of hormone-dependent tumours. We saw that this was already the case at the time of diagnosis.”
For the study, they closely looked at the efficacy of two substances found in coffee- caffeine and caffeic acid.
“The breast cancer cells reacted to these substances, especially caffeine, with reduced cell division and increased cell death, especially in combination with tamoxifen,” the researchers added.
“This shows that these substances have an effect on the breast cancer cells and turn off signaling pathways that the cancer cells require to grow.”
Hopefully, these new findings may encourage more women to consider focusing on their diet as well as the recommended medications and treatment options for breast cancer to reduce recurrence risk and halt tumor growth.
The findings of the study are now published in the journal Clinical Cancer Research.
