From Michael Greger, MD

The difference between a benign tumor and a malignant tumor is the ability to spread. No matter how big most tumors get, as long as they don't spread to other parts of the body, you're usually pretty safe.

Your body knows this, and so attempts to wall off any tumors by wrapping them in scar tissue. A benign tumor turns malignant when it learns how to break free by secreting enzymes (called metalloproteinases) that can dissolve the scar tissue cage your body encased it in. There are components of our diet, though, that can inhibit this jailbreak enzyme and keep the tumor in its place.

We know there are special phytonutrients in blue-green algae, green tea and in the spice turmeric that inhibit this tumor enzyme and thus may help keep tumors at bay. For the first time, though, a new study shows that berries also seem to contain substances that powerfully inhibit these tumor enzymes. The researchers conclude: "The raspberry extracts, blackberry extracts, and muscadine [grape] extracts, or the fruits themselves could potentially play a role in cancer prevention by blocking metastasis."

Cranberries are one of the cheapest (and healthiest) berries, but tend to only be available this time of the year, so make sure to buy extra and freeze them. Frozen in an airtight container they should keep for nearly a year.
