Patients often ask about diet as it pertains to their cancer diagnosis. Many patients come in having heard that “sugar feeds cancer.”  This is a common myth/misperception and it is simply not true. Eating a lot of sugar can contribute to obesity. Obesity is a risk factor that is linked to several types of cancer (Breast, Colorectal, esophagus, pancreatic, endometrial, kidney, thyroid and gallbladder). In addition to being a risk factor for certain types of cancer, obesity has many other negative implications for your health.
