MYTHS ABOUT CANCER IV

Myth: Microwaving plastic containers and wraps releases harmful, cancer-causing substances into food.

Fact: Microwave-safe plastic containers and wraps are safe to use in the microwave.

But plastic containers not intended for use in the microwave could melt and potentially leak chemicals into your food. So avoid microwaving containers that were never intended for the microwave, such as margarine tubs, take-out containers or whipped topping bowls. Check to see that any container you use in the microwave is labeled as microwave-safe.

 Myth: People with cancer shouldn't eat sugar, since it can cause cancer to grow faster.

Fact: Sugar doesn't make cancer grow faster.

All cells, including cancer cells, depend on blood sugar (glucose) for energy. But giving more sugar to cancer cells doesn't speed their growth.

Likewise, depriving cancer cells of sugar doesn't slow their growth.

This misconception may be based in part on a misunderstanding of positron emission tomography (PET) scans, which use a small amount of radioactive tracer — typically a form of glucose. All tissues in your body absorb some of this tracer, but tissues that are using more energy — including cancer cells — absorb greater amounts. For this reason, some people have concluded that cancer cells grow faster on sugar. But this isn't true.
