Busting prostate cancer myths

There’s a lot of confusion about prostate cancer. To help you learn more, here are three common myths and their scientifically-based rebuttals, courtesy of Science Daily and the US-based Fred Hutchinson Cancer Research Center.

Myth 1: high testosterone levels increase the risk of prostate cancer
Kristal says that although there’s a strong association between oestrogen levels and breast cancer, the same is not true of testosterone levels and prostate cancer.

Myth 2: fish oil (omega-3 fatty acids) decrease prostate cancer risk
Omega-3 fatty acids (including DHA, commonly found in fish) are often said to have an anti-inflammatory effect—but when it comes to prostate cancer, this effect seems to be reversed.

Two large studies, including one that Kristal led in 2011, have demonstrated that high blood levels of omega-3 fatty acids increase the chances of developing aggressive prostate cancer.

Myth 3: dietary supplements can prevent prostate cancer
Not so. According to Kristal, one study found that neither selenium nor Vitamin E prevent prostate cancer. A follow-up study found that Vitamin E increased the risk of developing the disease.
