Risk factors for Increased Risk of Bladder Cancer
History of bladder cancer
(High) coffee consumption
Studies linking coffee consumption with cancer are conflicting and inconclusive at this point, but there is a suggestion of a higher incidence of cancers of the pancreas, ovaries, bladder, and kidneys in coffee drinkers.
Increased Risk of Bladder Cancer can lead to
Recommendations for Increased Risk of Bladder Cancer
Green / Oolong / BlackTea (Camellia sinensis)
Regular and substantial consumption of green tea may provide protective effect against this type of cancer.
Caffeine/Coffee Avoidance
Studies linking coffee consumption with cancer are conflicting and inconclusive at this point, but there is a suggestion of a higher incidence of cancers of the pancreas, ovaries, bladder, and kidneys in coffee drinkers.
Soy Isoflavones (genistein, daidzein)
A higher dietary soy intake was associated with an increased risk of bladder cancer in a study of adults in Singapore
who were followed for three years or longer. [Cancer Epidemiol Biomarkers Prev 2002;11(12): pp.1674-7]
Vitamin E
Ten years of regular supplemental vitamin E intake, but not regular use of shorter duration was associated with a reduced risk of bladder cancer mortality in a study of 991,522 adults in the United States. [Am J Epidemiol 2002;156(11): pp.1002-10]
Vitamin C (Ascorbic Acid)
In a very large study, the regular supplementation with vitamin C was not associated with the risk of bladder cancer mortality.
