Tomatoes are particularly rich in the antioxidant lycopene. Lycopene may have particular power to stop healthy prostate cells from turning malignant. A study funded by the National Cancer Institute showed that prostate cancer was linked to diets high in this type of fat. Some studies suggest that regular physical activity may lower the risks of all types of cancer, including the kind that develops in the prostate. In early stages, prostate cancer generally has no symptoms, so most cases are detected by screening tests.
Some men do notice that they have to urinate more often or that their stream of urine is weaker.
But those changes can also arise from a less serious condition like an enlarged prostate. If you have any of these symptoms, see your doctor. He or she will use two basic screening tests. The tests may also detect slow-growing tumors that will never get large enough to harm you. But both tests can help doctors identify cancer early enough to save your life.
