Experts have said that coffee consumption may reduce the risk of colorectal cancer recurrence and all-cause mortality.
In a study published in the International Journal of Cancer, researchers said that consumption of more than four cups of coffee per day appeared to be associated with a 32% reduced risk for colorectal cancer recurrence compared with consumption of less than two cups per day.
In addition, consuming three to five cups of coffee per day seems sufficient to reduce the risk of dying among patients with colorectal cancer.
Abisola M. Oyelere, the study’s first author from Wageningen University & Research in the Netherlands, said in a comment that the study had assessed the association of coffee consumption with cancer recurrence and all-cause mortality [among patients with colorectal cancer] in the Netherlands.
According to her, evidence from the literature suggests that coffee consumption may help to reduce the risk for colorectal cancer and that coffee may be protective against colon cancer because of its heterogeneous mixture of compounds that possess antioxidant, anti-inflammatory, and anti-tumorigenic properties.”
She added that coffee consumption has been shown to improve liver function, and the liver is one of the common sites of metastasis. Coffee consumption is also hypothesised to improve bowel motility.
The researcher, however, declared that it is important for clinicians to understand the mechanism that underlies the association between coffee consumption and colorectal cancer prognosis before recommending coffee consumption to patients with colorectal cancer.
She further stated that it is important to answer the question of how coffee consumption may help to reduce the risk of cancer recurrence or all-cause mortality among patients with colorectal cancer, and as such, the Prof. Ellen Kampman-led research team will be focusing on this question using several approaches, including metabolomics.
