A 2014 clinical study found out high coffee intake can lower one’s chances of developing fatal and high-grade prostate cancer. The study established that as long you take 3 or more cups of coffee, your chances of fatal prostate cancer are below 11%. Another study on the BMJ Open also associated daily intake of one cup of coffee to reduce the risk of prostate cancer by 1%.
Today, prostate cancer is the second leading common type of cancer. The disease also ranks at number six in the biggest causes of death in men. According to BMJ Open, new cases have been on the rise in Asian countries such as China, Japan, and Singapore. However, developed nations have the highest number of registered cases – recording approximately 3 out of every 4 cases.
Support Studies and Research
Additionally, medical scientists have also linked coffee intake with a lower risk of breast, bowel, and liver cancers. However, scientists have not yet established conclusive evidence on the relationship between coffee and prostate cancer. Researchers however dug into research databases to find relevant cohort studies to further their understanding of the linkage. Most of the databases contained cohort studies that scientists had published in 2020. They trawled the data from 16:15 and made comparisons between high and low coffee intake and their effect on prostate cancer risks. The highest consumption level was 2-9 cups daily and the lowest was up to 2 cups.
The studies in the database included research conducted across North America(7), Japan (2), and Europe (7). Also, note the study cut across over 1 million men (1,081,586) – 57,732 of them developed prostate cancer. In comparison to the lowest coffee intake, the highest coffee intake reduced their risk by 9%. An additional daily cup of coffee reduced the risk by 1%.
Nonetheless, there might have been uncontrollable variables in the study. For example, the researchers might not have been able to classify the coffee. The method of brewing might have also varied per study. Therefore, the studies must not have been 100% accurate but provided an estimate to work within to establish the link between coffee and reduced risk of prostate cancer.
