Prostate cancer (PCa) patients who drink at least one cup of coffee per day may experience a significantly decreased risk of PCa recurrence or progression after treatment. This also applies to men who have a diagnosis of prostate cancer and opt to “watch and wait” and not receive any treatment.
In a study of 630 men aged 35-74 diagnosed with PCa from 2002 to 2005, drinking one cup of coffee per day was associated with a 56% decreased risk of recurrence or progression compared with drinking one cup or fewer per week. Drinking four or more cups per day and two to three cups per day was associated with a greater decrease than men who consumed only two cups a day.
For men who do not drink coffee, it is not possible to recommend that they start drinking coffee based on results from our observational study. Of course, men who might have conditions that may be aggravated by coffee should consult with their physicians as to whether it would be okay for them to drink a cup of coffee a day.
Bottom Line: This is a preliminary study that suggests that coffee may be beneficial for the treatment of prostate cancer. As my wonderful Jewish mother would say, “It may not help, but it probably voidn’t hoit!”
