They discovered fat cells secrete a protein that accelerates the spread of the disease. The protein, known as CCL7, sends signals to cancer cells encouraging them to spread to nearby organs, the French study found. Though their experiments were conducted in mice, the researchers noted human fat cells also release CCL7. They hope their findings could lead to new therapies to combat the disease,
particularly in obese patients. Read more
