New Study Examines Antioxidant Impact on Prostate Cancer

by Tatya H.P.

Prostate cancer as one of the most common types of cancer in men according to the American Cancer Society. Fortunately if caught early, the prognosis is good. Even better than treating it, is of course, avoiding it altogether. The search for the cause of prostate cancer is ongoing and a recent study was recently completed.

An eight year study of 29,361 men has just been completed. The study examined the impact of antioxidant supplements on the rate of prostate cancer. "There has been definite interest in their use, based on a few earlier studies that have been done" said lead researcher Richard B. Hayes, senior investigator in the division of cancer epidemiology and genetics at the U.S. National Cancer Institute.

Reporting in the Feb. 15 issue of the Journal of the National Cancer Institute, Hayes' team calculated the risk of prostate cancer for 29,361 men aged 55 to 74, all of whom were participants in the Prostate, Lung, Colorectal and Ovarian (PLCO) Screening Trial.

Some of the data that was analyzed included the amount of common antioxidant supplements including vitamin C, beta carotene, and vitamin E. Some of the men had been taking these supplements for many years prior to the study.

Over the total eight year study period, 1,338 men developed prostate cancer. The results indicate that the use of antioxidant supplements had no positive impact on the risk for prostate cancer for most nonsmokers. Beta carotene supplements did have a positive impact among men that had low dietary intake of beta carotene.

Vitamin E did have a positive impact for smokers according to the research. This was consistent with previous trials.
Although the three supplements studied in this trial showed little help in preventing prostate cancer, previous trials that examined other supplements did show very encouraging results.

Fish oils, which contain EPA and DHA, were found to reduce prostate cancer by 11% in men that consumed about 470 mg./day. Selenium has been found to cut prostate cancer in half. Over five clinical trials have supported this. It is recommended that men take a 200 micrograms of selenium daily.

Knowing Your Cancer Risk

Prostate cancer is the most common cancer among American men after skin cancer, according to the National Cancer Institute.

Based on this statistic, most people might assume that the majority of American men are well educated about how best to fight prostate cancer, where to turn for more information and what support group an uncle or golf buddy relied on during their respective battles with the disease.

Unfortunately, this is not the case. While women regularly host breast cancer awareness and fund-raising walks across the country, men have been less proactive on matters related to their health, including essential measures such as soliciting second opinions and researching treatment options. The result of this passive approach is that the average man does not always make good, informed decisions about his own health care.

A new program is encouraging men to alter their approach to health care, at least when it comes to battling prostate cancer. Us TOO International Prostate Cancer Education and Support Network, along with Y-ME National Breast Cancer Organization, have founded the "Partner's Program" to help men with prostate cancer and their partners face the diagnosis together, encourage them to seek information regarding treatment options, and ultimately, make more well-informed treatment decisions.

This program clearly responds to an unmet need. Recently, an Us TOO- and Y-ME-commissioned survey found that, although the majority of men with prostate cancer have heard of both surgery and radiation as treatment options, up to 38 percent don't know that other treatments, such as hormonal therapy, even exist. Even more alarming, less than 50 percent of men with prostate cancer take the time to get a second opinion on their diagnosis or proposed treatment. These facts are sure to concern anyone who loves a man at risk of developing prostate cancer.

The good news for wives and partners is the survey found that men don't want to face prostate cancer treatment choices alone, making a resource like the "Partner's Program" attractive for both men and women. While men are not typically as open as women on subjects such as prostate cancer, the survey found that almost 70 percent of men age 50 and older indicated that they would like their partner to play an active role in the process of choosing an appropriate course of therapy.

Now, with the help of the "Partner's Program," the average American man may become more proactive about his health.

How to Fight Prostate Cancer

by Tatya H.P.

Over the past few years Prostate Cancer has been targeted by health authorities as the largest hidden killer of men over 45 years of age. Although there have been advances in education and general public awareness, men are still demonstrating reluctance to acknowledge the need for vigilance in their everyday lives.

There are a number of ways that men can reassure themselves however.

Here is a list of facts and suggestions collated from a number of sources that you should know about.

One in every 6 men will suffer from prostate problems in their lives. So there is no need to feel isolated or a victim. Just take action and get to a doctor quickly at the first sign.
It is almost certain that quick action will lead to successful recovery. The sooner you visit your doctor and get referred to a Urologist the better your chances of successful treatment.

There is hope for the future. In 2002, scientists at Liverpool University in the UK isolated the gene that promotes the spread of prostate cancer. This information is still being explored to hopefully produce new drugs which will assist treatment of Prostate cancer outside of the normal Chemotherapy regimes currently in use.

Dietary habits are the common thread in most of the literature about prostate cancer.

• Dairy products should be eliminated and replaced by soya. Just a couple of glasses of soy milk a day can have dramatic effects.
• Lyocopene contained in tomatoes is another factor showing up in studies as an effective preventative element of a prostate cancer fighting diet. Eating one moderately sized tomato a day also provides approximately 4 mg of lycopene. Other tomato products, such as an 8-ounce portion of tomato juice or tomato paste may provide up to 25 mg of lycopene. See www.naturalhealthlive.com/Lycopene.html
• Other fruits and vegetables are also recommended, such as avocadoes, pumpkins, beans and carrots and green leafy vegetables like spinach.
• Garlic, which seems to pop up in every preventative healthy diet plan is also recommended as it contains allicin, which decreases the proliferation of cancer cells.
• Selenium which is found in garlic, tomatoes, and broccoli has also been shown to be effective.

Cut back on salt and seasonings as these have been linked to cancer.

Finally, green tea is a popular choice as a beverage so drink at least 6 cups a day.

All in all there are plenty of reasons to be positive about controlling the risk of contracting prostate Cancer. A healthy diet as outlined above, coupled with most others advocated by Dietician everywhere, will dramatically reduce your concerns and help you lead a normal healthy long life.

Could Pomegranates Be The New Prostate Cancer Natural Cure?

by Tatya H.P.

Pomegranates have long been used in traditional folk remedies to treat sore throats, inflammation, and rheumatism. And recent scientific research has suggested they are also potentially effective in both preventing and treating prostate cancer.

One study, conducted on human prostate cancer cells in lab dishes, at the University of Wisconsin, found that there were dose dependant improvements. Another study at the same facility injected mice with human prostate cancer cells. These mice developed malignancies. Some mice were fed plain water, whilst two other groups of mice were given water mixed with different concentrations of pomegranate extract.

Those mice that had water only had tumors that grew much faster than the pomegranate and water groups. The quantities given to the mice were comparable to that which people might get if they drank pomegranate juice on a daily basis. And whilst pomegranate juice hasn't been tested on humans with prostate cancer yet, the results are very good.

The study did not indicate what aspects of pomegranate juice were responsible for slowing down prostate tumour growth. But the scientists involved did mention the antioxidant polyphenolic compounds, which are more effective than green tea and red wine.

Pomegranate extract not only inhibited the growth of cancer cells, it also worked by another means - apoptosis.

Apoptosis refers to a way that cells can die. Cancer growths are characterized by an uncontrolled growth of cells that do not follow the normal processes of cellular differentiation of regular, healthy cells. Cellular differentiation means that the characteristics of a cell change and get the functions that a mature, healthy cell would. For example, liver cells have specialized liver functions, as do prostate, breast, kidney, and all other types of cells. This is normal and healthy.

In tumour growths, although some cells fully differentiate, many only differentiate partially, and some not at all. And the tumors which have more undifferentiated cells grow faster. So, inducing cellular differentiation is one approach to cancer treatment. The other two ways that doctors and researchers try to treat cancer is by causing the death of cancerous cells. They do this through apoptosis, mentioned above, and necrosis.

In apoptosis, cell death is programmed into the cell when it is 'born'. So the cell dies in a more natural way that is less destructive on its environment. By this I mean it doesn't cause inflammation and the damage associated with it to neighboring cells that may be healthy. Cells die either when they reach cellular old age or when their death benefits the body as a whole. Necrosis, on the other hand, does cause inflammation.

Generally, prostate cancer grows very slowly, although it is unpredictable and can grow quickly and spread.
