Some research calls into question the effectiveness of frequent prostate cancer screenings. Apparently there’s not much difference between two- and four-year tests. Robert Preidt of HealthDay News explains:

The researchers looked at more than 17,000 men who had prostate specific antigen (PSA) testing every two years or every four years. Among 4,202 Swedish men screened every two years, the overall incidence of prostate cancer diagnosis over 10 years was 13.14 percent, compared to 8.41 percent among the 13,301 Dutch men who were screened every four years, said the researchers from Erasmus Medical Centre in Rotterdam, The Netherlands.


The total number of interval cancers -- those diagnosed based on symptoms during the years between screening tests -- was 31 (0.74 percent) among the Swedish men and 57 (0.43 percent) among the Dutch men.

The differences in the interval cancer rates and aggressive interval cancer rates between the two groups were not statistically significant, the study authors said. This indicates that two-year screenings don't reduce the number of interval cancers, as might be expected.

Wait! A money-making medical test might not actually be as good as they say it is—no! You’re joshing me. Dr. Fuhrman is hardly awed by PSA screenings. He shares his thoughts in a previous post:

Incredible as it may seem, the PSA test does not accurately detect cancer. If you are over 60 years old, the chance of having a prostate biopsy positive for cancer is high, and the likelihood you have prostate cancer is the same whether or not you have an elevated PSA. More and more studies in recent years have demonstrated that prostate cancer is found at the same high rate in those with lower, so-called “normal” PSAs as those with elevated PSAs.1 An interesting study from Stanford University in California showed that the ability of PSA to detect cancer from 1998 to 2003 was only 2 percent. The elevations in PSA (between 2 and 10) were related to benign enlargement of the prostate, not cancer.


Remember, the pharmaceutical/medical industry is big business. Too often, treatments are promoted from a financially-biased perspective, leading to overly invasive and aggressive care without documented benefits.

The Cancer Blog knows flaxseed is one heck of a super food. Take a look:

Flax, also known as Common Flax or Linseed, is an annual plant that grows to 120 cm tall, with slender stems. Native to the region extending from the eastern Mediterranean to India, its leaves are green, its flowers blue, its fruit round and containing glossy brown seeds. Grown for both its seeds and its fibers, parts of this plant are used to make fabric, dye, paper, medicines, fishing nets, and soap. The seeds, like what sit in my refrigerator, come in two forms -- brown and yellow or golden. The yellow, golden variety is the one most often consumed.


Consumption of flax seed is good for several reasons, thanks to lignans that power it with nutrition. It contains beneficial levels of omega-3 fatty acids, promotes heart health, lessons the severity of diabetes, and has anti-cancer properties. A series of research studies at the University of Toronto have shown that flaxseed can reduce tumor growth in mice, particularly the tumors found in human post-menopausal breast cancer.

Dr. Fuhrman’s down with flax too. From Disease-Proof Your Child:

Flax seeds are rich in lignans and omega-3 fatty acids, and scientific studies have confirmed that flax seeds have a positive influence on everything from cholesterol levels and constipation to cancer and heart disease. Use ground flax seed in oatmeal, or add them to whipped frozen bananas, stewed apples, and cinnamon and nut balls. Keep in mind that the scientifically documented benefits from flax seeds come from raw, ground flax seed, not flax seed oil.
