Flaxseed may stall prostate cancer growth Jun 4, 2007
The men were randomized into four arms: a control group that maintained their regular diets, men who took flaxseed (30 grams per day), men who restricted their dietary intakes of fat (to less than 20 percent of their total calories) and men who took flaxseed and also restricted their intake of dietary fat ... These scores indicated that cancer cells in the two flaxseed groups grew at a significantly slower rate (roughly 30 to 40 percent slower) than the placebo or dietary fat groups. (Xinhuanet, China)
Ginseng, Flaxseed May Help Cancer Patients Jun 3, 2007

Men who were taking flaxseed, in either the low-fat or normal diet group, had the slowest rate of tumor growth, reported researchers at Duke University. (Forbes)
High-Fat Diet May Increase Ecstasy Danger May 31, 2007
On the other hand, the researcher added, body-temperature regulation is a complex process that involves many factors other than dietary fat. It's not clear, Sprague noted, whether having a pre-ecstasy burger and fries might boost the odds of hyperthermia, since the animal study looked at long-term fat intake. (MEDLINEplus)

Statin use linked with decreased prostate cancer mortality rates; lower PSA levels May 21, 2007
In recent years, research has indicated a possible link between dietary fat intake and prostate cancer. Research presented today at the 102nd Annual Scientific Meeting of the American Urological Association explores the effect statin medications (which work to reduce low-density lipoprotein, or LDL, levels) may have on prostate-specific antigen, the incidence of prostate cancer, and mortality due to prostate cancer.

High insulin levels impair intestinal metabolic function Apr 25, 2007
Chylomicrons transport dietary fat from the intestine to the rest of the body. The researchers note that excessive insulin appears to alter the mechanics of blood vessel walls, allowing chylomicrons and cholesterol to build up in them, which, over time, creates blockages in the blood stream, leading to heart problems.
