Do tomato-based foods really help prevent prostate cancer?

It's National Prostate Cancer Awareness Month, a good time to clear up some confusion.

Maybe you've heard that eating tomato-based products, such as ketchup and red pasta sauce prevents prostate cancer.

Scientists at the Fred Hutchinson Cancer Research Center say that's a myth. The vast majority of studies show no association.

Researchers at Fred Hutch conducted the largest study ever to see if foods that contain lycopene - the nutrient that puts the red in tomatoes - actually protects against prostate cancer. They examined 3,500 men and found no association between lycopene levels in their blood and the disease.

Some men believe high testosterone levels increase the risk of prostate cancer. Again, this is a myth.

While there is a strong relationship between estrogen and breast cancer, there is no association between testosterone levels and prostate cancer risk.

And let's clear up one more misconception. Cancer experts say there is no evidence that fish oil decreases the risk f prostate cancer. But Omega-3 fatty acids are good for your heart.
