Karina,
I am personaly a believer that sugar is directly or indirectly helping cancer cell growth based on various research papers although most are not specifically devoted to prove the point.
But look at this extract from an article by a Mayo Clinic MD who may well know better:

Debunking cancer myths: An interview with a Mayo Clinic specialist
"People with cancer shouldn't eat sugar, since it can cause cancer to grow faster.

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. Doctors use PET scans to help determine the location of a tumor and see if it has spread.

During a PET scan, your doctor injects a small amount of radioactive tracer — typically a form of glucose — into your body. All tissues in your body absorb some of this tracer. But tissues that are using more energy — exhibiting increased metabolic activity — absorb greater amounts.

Tumors are often more metabolically active than healthy tissues. As a result, they may absorb greater amounts of the tracer. For this reason, some people have concluded that cancer cells grow faster on sugar. But this isn't true."

Here are a few of the articles that imply the opposite view:

Glucose metabolism could be used to selectively destroy cancer cells
