Cancer and diabetes linked by hidden mechanism, says study.

A new study has revealed that cancer patients have insulin resistance, which can cause cancer cells to multiply and lead to muscle loss. Insulin resistance can also be hard to identify in cancer patients as they already experience symptoms such as fatigue. The study suggests that oncologists should check patients' blood sugar levels and treat insulin resistance if found. The next step is to determine who is at high risk of developing insulin resistance and whether treatment has a positive effect on patients.
