👉 Calyceal is a term used in medicine to describe a type of cancer that occurs when cells grow out of control and divide uncontrollably. It's also known as "uncontrolled cell growth" or "emerging tumour." Calyceals are often seen in people who have never had any other kind of cancer before, or who have been diagnosed with cancer but have not yet shown symptoms. They can be either benign (meaning they don't grow out of control) or malignant
