From my research, yes it can. I read a study that said patients who fast during chemotherapy treatments fare better too.
The mechanism seems to be that during periods of fasting, normal cells "hunker down" and restrict the consumption of nutrients and other materials. Cancer cells don't do this though and continue to consume the nutrients, which are actually chemotherapy drugs in the patients.
Fasting therfore increases the absorption of chemo by the cancer cells and reduces the consumption by normal cells keeping the patient healthier.
Fasting also enables the body to more completely rid itself of cancerous cells by consuming them in the absence of alternative sources of nutrition.

Lots of reasons why fasting is a good thing.
