Study Shows Good Outcome for Delayed Prostate Surgery


Men with early prostate cancer who put off surgery is almost the same as men who had prompt surgery. On average, their tumors were no likely to develop into a more aggressive form than men who had surgery immediately after diagnosis. Additionally, after eight years, .9 percent of men who delayed surgery had died compared to .7 percent of men who had prompt surgery.

“Our findings show that if a man is diagnosed with a localized low-risk prostate cancer, there is no rush to decide which treatment choice (is) best,” said lead researcher Dr. Benny Holmstrom, of Gavle Hospital in Sweden.

The results add to data that some patients can safely opt for “active surveillance” — where the prostate cancer is monitored with regular PSA blood tests, digital rectal exams and possibly prostate biopsies and costly, painful surgical procedures are avoided.

A study published last year in the Journal of the National Cancer Institute estimated that since 1986, around 1 million U.S. men received unnecessary treatment for prostate tumors that were not life threatening.

As experts and health providers are increasingly calling for expanded use of active surveillance in monitoring prostate cancer, this study is particularly significant. However, Holmstrom warned that further, long-term studies are still needed to insure that active surveillance is truly the best option for prostate cancer patients.

Beta-Sitosterol and Your Prostate Health


For men who are suffering from prostate related symptoms and are seeking for safe alternative therapies, beta-sitosterol may be the answer.

Beta-sitosterol is a plant sterol found in several everyday foods and has effectively been shown to -
* Inhibit growth of prostate cancer cells and can even destroy the cells through protein phosphatase.
* Decrease inflammation by binding to the prostate.
* Improve urinary flow and help with urinary incontinence and urgency.
* Prevent difficult urination.

To incorporate beta-sitosterol in your diet, use vegetable oil as this is its best food source. Canola, corn and soybean oil, vegetable shortening, margarine made from corn or soybean oil, and tofu or soybean mayonnaise all contain high amounts of beta sitosterol.

Other significant sources of beta sitosterol are avocados, grape leaves, fava beans, saw palmetto, pumpkin seed, cashew fruit, rice bran, wheat germ, pistachio nuts, almonds, hazel nuts, walnuts, macadamia and pecans.

Another pleasant source of beta sitosterol is unsweetened baking chocolate. Now brownies will be a good source of beta sitosterol by using ingredients with high beta sitosterol – vegetable oil or margarine, unsweetened baking chocolate with chopped nuts of your choice.

Beta sitosterol is safe when taken in normal amounts such as amounts found in food. Clinical studies though have shown it may cause side effects, most of which are not usually dangerous.

An added benefit of beta-sitosterol is it has been found to lower cholesterol, by inhibiting the amount of cholesterol that is permitted to enter the body.

Coffee and Prostate Health: Is it Bad for You?


Is coffee good or bad for men’s health? A recent study suggests that coffee and caffeine may be safe (for now) in regards to prostate cancer, but components within coffee can negatively affect men who have benign prostatic hyperplasia (BPH).

For men who have BPH, drinking coffee can be detrimental because caffeine can stimulate an already overactive bladder, which means it can increase urinary frequency and urgency and may even result in urge incontinence. Caffeine acts on the bladder in several ways. First, it increases how fast the bladder fills up by increasing the rate of urine production. Second, caffeine enhances the sensation and contractility of the bladder, thus making the organ feel a potentially erroneous urge to empty.

Caffeine can also irritate the bladder because it is a theoxanthine, which is a family of drugs that includes theobromine (found in chocolate) and theophylline (found in tea). Theophylline also stimulates and irritates the bladder; however, tea contains half as much caffeine as coffee does, and green tea specifically contains even less.

The impacts of coffee on prostate cancer have piqued the interests of researchers worldwide. According to recent research conducted by Dr. Chang-Hae Park from the National Cancer Center in South Korea, there is no association between prostate cancer and drinking coffee, but there is still some controversy. Park and his team evaluated the results of 12 studies that compared coffee intake and prostate cancer risk. Eight of the studies were case-control studies and four were cohort studies.

The controversial part is that although the investigators found a significant harmful association between coffee consumption and prostate cancer risk in seven of the eight case-control studies, they also explained that the studies had severe limitations that affected the outcomes. None of the cohort studies showed any significant association between coffee consumption and prostate cancer. Therefore, while Park and his team reported there is no evidence that coffee consumption has an effect on prostate cancer, further prospective cohort studies are needed.

The journal Molecular Nutrition and Food Research published a study in 2009 in which researchers evaluated the impact of coffee and tea on prostate health. The investigators’ results showed that no apparent relationship with prostate cancer existed; however, the evidence from animal and in vitro studies suggested that tea, especially green tea, is a healthier choice than coffee for prostate health.

A study at Umea University in Sweden analyzed the effects of both filtered and boiled coffee on the incident of cancer. From a study population of more than 64,000, there were 3,034 cases of cancer, with up to 15 years of follow-up. The investigators did not find an association between consumption of filtered or boiled coffee and all types of cancer combined, or for prostate or colorectal cancer in particular.

Another large study conducted by Harvard evaluated 50,000 men. Researchers used data from the Health professionals’ follow-up study to determine if there was an association between the consumption of regular and decaffeinated coffee and prostate cancer. The investigators found that over two decades, 4,975 cases of prostate cancer were diagnosed. According to Kathryn Wilson, Ph.D., from Harvard Medical School and the Harvard School of Public Health, she and her team “specifically looked at different types of prostate cancer, such as advanced vs. localized cancers or high-grade vs. low-grade cancer.” They found that men who had the highest intake of coffee had a 60 percent lower risk of advanced prostate cancer. Wilson noted: “Our results do suggest there is no reason to stop drinking coffee out of any concern about prostate cancer.”

Coffee and caffeine have an impact on other aspects of your health outside of prostate health. Some studies suggest that consuming coffee and caffeine is associated with a reduced risk of certain diseases. One study published in Cancer Causes & Control in January 2011 found that drinking three or more cups of coffee daily was associated with a 44 percent reduced risk of developing liver cancer in a group of older Chinese adults.

In addition, the Journal of Alzheimer’s Disease reported the results of a recent review study that explored a relationship between coffee and dementia. The investigators concluded that coffee drinking may be associated with a reduced risk of dementia and Alzheimer’s disease.

But despite these positive studies, a combination of coffee, caffeine, and stress can be very unhealthy. Here are some reasons why these three don’t always mix well.

1. Coffee raises stress hormone levels. Elevated levels of stress hormones, including norepinephrine and especially cortisol, are responsible for raising heart rate and blood pressure. When you combine coffee/caffeine with stress, you place your stress hormones on high alert, which in turn puts your heart rate and blood pressure in unhealthy states as well. Elevated stress hormones also weaken your immune system. If you reduce your coffee/caffeine consumption, you will lower your stress hormone levels, blood pressure, and heart rate, and help preserve your immune system health.

2. Coffee contributes to weight gain. The higher cortisol levels associated with coffee consumption are also linked to insulin resistance, increased appetite, and cravings for fatty foods. High cortisol levels can also contribute to fat deposits in the abdomen, which is a risk factor for heart disease.

3. Coffee plus stress may equal heart attack. Coffee consumption can increase stress, which is a known risk factor for heart attack, heart palpitations, and elevated homocysteine, another risk factor for heart disease. If you are stressed, coffee is not a health beverage for your heart.

4. Stress and coffee affect the brain. Stress has a detrimental effect on the parts of the brain responsible for planning, decision making, and reasoning. When you add caffeine, your mental abilities, mood, and memory can suffer, because caffeine interferes with blood flow to the brain. To keep mentally sharp, reduce your use of coffee and caffeine.

5. Stress and coffee disrupt sleep. Stress and worry can keep you awake, and the stimulating effects of caffeine can disrupt your ability to sleep. If you eliminate coffee, you may regain the ability to sleep.

6. Stress and coffee irritate your GI tract. Coffee and caffeine are highly acidic, which can increase the risk of heartburn, ulcers, and irritable bowel syndrome. Reduce your coffee intake, and reduce your risk of these gastrointestinal problems.

An occasional cup of coffee will not likely have a negative effect on prostate health or your overall health. But if you have BPH, coffee consumption should be limited. If you want to enhance prostate health and general well-being, however, the better choice is green tea.

Eat Your Way to a Healthy Prostate


It is possible to treat yourself with nutrition. It is important, however, to first have that check-up with the doctor.

Prostate nutrition and health have a relationship. One may be able to avoid prostate irregularities by overcompensating with proper prostate nutrition.

Carotenoid
There are two common types of carotenoid – lycopene and beta carotene. Lycopene is a pigment which gives certain fruits (watermelon, red guava, red grapefruits, papaya) and vegetables (tomatoes) their red color. Beta carotene is an orange pigment that is commonly found in carrots and sweet potatoes. Carotenoid is a powerful antioxidant that is linked in some studies to decrease risk of prostate cancer. Antioxidants are molecules that prevent, or at least slow oxidation. Oxidation can create free radicals, which may cause different types of cancer. Enjoy the benefits of carotenoid by eating more tomatoes, processed tomato products, carrots and sweet potatoes.

Cruciferous Vegetables
Eat more broccoli, cauliflower, kale, cabbage, brussel sprouts and bok choy. A recent study found that men who ate cruciferous vegetables more than once a week were 40% less likely to be diagnosed with prostate cancer than men who rarely ate them. Phytochemicals found in cruciferous vegetables – sulforaphane – can stimulate enzymes in the body that detoxify carcinogens before they damage cells. Through different mechanisms, two other compounds found in cruciferous vegetables — indole 3-carbinol and crambene — are also suspected of activating detoxification enzymes. Another way cruciferous vegetables may help to protect against cancer is by reducing oxidative stress. Oxidative stress is the overload of harmful molecules called oxygen-free radicals, which are generated by the body. Reducing these free radicals may reduce the risk of prostate cancer.

Fiber
Fiber is found in fruits, vegetables and whole grains, the more natural and unprocessed the food, the higher the fiber. It keeps the digestive system clean and healthy which keeps the food moving through the digestive tract moving the cancer-causing compounds out before they can create harm. Fiber can also eliminate excess testosterone in the body; thus, a high-fiber diet can aid in the regulation of your body’s hormone levels and may help reduce the risk for prostate cancer.

Omega 3 Fatty Acids
Eat oily fish such as wild salmon, mackerel, sardine and herring for their beneficial EPA/DHA fatty acids which help reduce production of arachidonic acid in the body. In connection, reduce intake of saturated fats and omega 6 fats. Saturated fats and omega 6 fats are not good for the body. Once consumed, they are converted by our body into arachidonic acid which the body needs to get rid of by producing a bad enzyme called 5-lipoxygenase (5-LOX). This 5 LOX enzyme directly stimulates prostate cancer cell proliferation. Further, 5-LOX is metabolized by the body to 5-HETE, which is a metabolite that prevents prostate cancer destruction.

Soybeans
Eating soy products (such as soy milk, tofu, soybean oil, soybean flour) causes a build up of isoflavones in the prostate. Isoflavones, an active ingredient in soy products appears to promote a process where cells initiate their own death (apoptosis). By encouraging apoptosis, soy isoflavones may be preventing cancerous cells from growing and spreading. Isoflavones may also inhibit the growth of new blood vessels, which is necessary for tumor survival. As cancers grow, they need nutrients that are carried to them via blood vessels. If new blood vessels cannot be grown as the cancer develops, the tumor growth will be slowed or stopped. Also, the phytoestrogens-nonsteroidal plant compounds in soy beans help to regulate imbalanced hormone levels (elevated levels of testosterone may increase risk of developing prostate cancer).

Zinc
Although there is mix result in studies on zinc and prostate health, zinc has long been a target of prostate cancer research because it is found in high concentrations in the prostate. Cancerous prostates have much less zinc than normal prostates. Zinc deficiency in normal prostate epithelial cells not only induces DNA damage itself, but also may impair the cell’s ability to respond to DNA damage, increasing the risk of prostate cancer development. Adequate zinc levels are essential for maintaining healthy prostate cells, but zinc supplementation may not prevent already cancerous prostate cells from growing. Also, studies show increased cancer risk with very high dose or long-term zinc supplement use. As with most therapeutics, higher doses do not always equate with an increase in efficacy. Increase zinc containing foods in your diet such as seafood (especially oysters), pumpkin seeds, eggs and brewer’s yeast. Lean meat also contains zinc. Eat organically grown food if possible, as pesticides can reduce zinc uptake.

Green Tea
Drinking 4-6 cups of green tea daily may help prevent prostate cancer. The polyphenols found in green tea attack the growth factors and protein, interrupting the growth process of tumors. Earlier studies also show that the same natural plant substances may also help prevent the start of prostate cancer itself. The phytochemicals in green tea seem to increase the number of enzymes that help convert carcinogens in the body to a harmless form. Green tea can have side effects including increased stomach acidity and it’s still unclear whether high doses cause liver damage.

Limit dairy consumption
Diets high in dairy products and calcium may be associated with small increases in prostate cancer risk. Moderate your dairy consumption, and don’t overdo calcium¬ supplements or foods fortified with extra calcium.
