They say prevention is better than cure. So here are some preventive measure that you can use:
Vitamins and medication
Studies reveals that eating and taking the following vitamins and food type help reduce and prevent prostate cancer:
- Dietary selenium, Vitamin E, lypocene, Vitamin D and soy foods - supports protective roles in reducing prostate cancer
- Estrogens from fermented soybeans and other plant sources (called phytoestrogens) - may also help prevent prostate cancer. The selective estrogen receptor modulator drug toremifene has shown promise in early trials.
- Two medications which block the conversion of testosterone to dihydrotestosterone, finasteride and dutasteride - have also shown some promise. The use of these medications for primary prevention is still in the testing phase, and they are not widely used for this purpose. The initial problem with these medications is that they may preferentially block the development of lower-grade prostate tumors, leading to a relatively greater chance of higher grade cancers, and negating any overall survival improvement.
- Eat healthy, well balanced diet rich in fiber, and to reduce intake of meat.
- Eating cauliflower, broccoli, or one of the other cruciferous vegetables, more than once a week were 40% less likely to develop prostate cancer than men who rarely ate those vegetables - A 2007 study published in the Journal of the National Cancer Institute found. The phytochemicals indole-3-carbinol and diindolylmethane, found in cruciferous vegetables, has antiandrogenic and immune modulating properties.
More frequent ejaculation also may decrease a man's risk of prostate cancer. One study showed that men who ejaculated five times a week in their 20s had a decreased rate of prostate cancer, though other studies have shown no benefit.
The results contradict those of previous studies, which have suggested that having had many sexual partners, or a high frequency of sexual activity, increases the risk of prostate cancer by up to 40 percent. The key difference is that these earlier studies defined sexual activity as sexual intercourse, whereas this study focused on the number of ejaculations, whether or not intercourse was involved.
Another study completed in 2004 reported that "Most categories of ejaculation frequency were unrelated to risk of prostate cancer. However, high ejaculation frequency was related to decreased risk of total prostate cancer." The report abstract concluded, "Our results suggest that ejaculation frequency is not related to increased risk of prostate cancer."
A 2008 study showed that frequent masturbation, of about two to seven times a week, at the ages of 20s and 30s, increases the risk of having prostate cancer. While frequent masturbation, once a week, at the age of 50s decreases the disease risk.
