Alternative medicine
By Mayo Clinic staffNo complementary or alternative bladder cancer treatments have been found to cure bladder cancer. But doctors are studying ways to prevent bladder cancer, including some complementary and alternative approaches. If you're worried about your risk of bladder cancer or that your cancer could recur, you may be interested in trying complementary and alternative treatments. Talk to your doctor about your options.
Vitamins
Fruits and vegetables are the safest way to get your vitamins. Some research suggests larger doses of certain vitamins, such as vitamin E, in pill form may help reduce the risk of bladder cancer. But other studies haven't found this.
More study is needed to understand what dose is safest and most effective. Until then, focus on eating a wide variety of fruits and vegetables that are rich in vitamins. If you're interested in vitamin supplements, ask your doctor about what doses may be reasonable.
Green tea
Drinking green tea has been linked to many health benefits. But whether it can reduce the risk of bladder cancer isn't clear. Animal studies have shown promise, but studies in humans have been mixed. For example, one study showed that people who drink the most green tea have a reduced risk of bladder cancer, while another study found that drinking green tea over many years increased the risk of bladder cancer. More study is needed to understand whether green tea is helpful or harmful when it comes to preventing bladder cancer.
