Pre-Existing Diabetes and Cancer
People with pre-existing diabetes that are now being treated for cancer, may have difficulty controlling their blood sugar levels. Diabetes treatments often need to be adjusted to help get blood sugar levels under control. For those with type 2 diabetes, insulin is often used, and is usually started around the time that steroids are given. Other aspects of treatment include diabetes education and a referral to an endocrinologist for consult.
Although diabetes is not usually the primary concern for those dealing with cancer, the goal is to keep blood sugar levels within a reasonable range to prevent symptoms of high blood sugar levels, to prevent delays in cancer treatment and reduce risks of infection during treatment.
