Doctors don't know what causes Paget's disease of the breast. The most widely accepted theory is that the disease results from an underlying ductal breast cancer. The cancer cells from the original tumor then travel through milk ducts to the nipple and its surrounding skin.
Glucose in the bloodstream provides the primary fuel for all body tissues. Blood glucose levels are highest during the digestive period after a meal. Your blood sugar is lowest when the stomach and intestines are empty. Under normal circumstances, the body tightly controls the amount of insulin in your blood. An organ called the pancreas, which is tucked behind the stomach releases the hormones insulin and glucagon to regulate blood sugar levels.
When the blood glucose level goes up. 1  Blood sugar (glucose) rises; 2  The pancreas detects the rise; 3  The pancreas pumps out insulin into the blood; 4  Insulin helps the uptake of glucose into muscles and other cells; 5  This causes the blood glucose level to fall to its normal set point; and. 6  The pancreas detects the fall and switches off insulin production. When the blood glucose level goes down. Blood sugar (glucose) drops; The pancreas detects the drop in blood sugar; The pancreas switches on the output of glucagon into the blood; Glucagon signals the liver to break down glycogen into glucose;
