I would be careful to believe everything Mercola believes. He is known by many in the medical field to be a fear mongering scam artist.

That is pretty much the opinion I have of Mecola lately.  I used to have more respect for him, but seems lately he is just going with whichever way the wind chooses to blow rather than to rely on real research and common sense.

Plenty of articles on the other side of the fence.

The first link simply states the same exact words as the second link.  And the only study I saw them refer to only looked at one type of cancer and was conductred from a participant questioneer, not a direct study on cancer cells.

There are other sources showing that sugar does in fact increase cancer cell growth.  Here is one article discussing a study reported in the journal Cancer Research:

Here is a link to the research abstract:

And another general article on the subject:

Here is another study discussing glucose reduction diets or glucose use inhibition reducing cancer growth:

"Malignant cells are known to have accelerated metabolism, high glucose requirements, and increased glucose uptake."

"Here, we report that fructose provides an alternative substrate to induce pancreatic cancer cell proliferation. Importantly, fructose and glucose metabolism are quite different; in comparison with glucose, fructose induces thiamine-dependent transketolase flux and is preferentially metabolized via the nonoxidative pentose phosphate pathway to synthesize nucleic acids and increase uric acid production. These findings show that cancer cells can readily metabolize fructose to increase proliferation. They have major significance for cancer patients given dietary refined fructose consumption, and indicate that efforts to reduce refined fructose intake or inhibit fructose-mediated actions may disrupt cancer growth.
