WHY JUST ONE TYPE OF CANCER?
ANCHOR LEAD: WHY DOES DIET HELP IN COLORECTAL CANCER BUT NOT IN OTHER TYPES OF CANCER? ELIZABETH TRACEY REPORTS
Consuming lots of fruits and vegetables doesn’t help women with breast cancer reduce their risk of the disease returning. Ditto for prostate cancer and other common forms of the disease, but a recent study found that in colorectal cancer, a diet that relied more on these foods, plus whole grains, fish, and chicken, did reduce recurrence. Michael Choti, a colon cancer expert at Johns Hopkins, offers his opinion.
CHOTI: First of all I think even in colorectal cancer it’s difficult to get a clear association or correlation, because diet is multifactorial and it also depends on the individual genetics and so forth, but colorectal cancer we don’t know. There may be some reasons that because it’s indeed an intestinal source of the cancer it may be affected to a greater extent by dietary factors than situations like breast cancer, just as lung cancer is more correlated with inhalation exposures such as smoking. :31
