Endometrial cell breakdown during menstrual cycle.  - Elimination of potentially harmful self-reactive lymphocytes. - Death of host cell that have served a useful purposes . Eg. Neutrophils in an acute inflammatory process, Lymphocytes at the end of an immune response . B.

Bladder Cancer Bladder cancer begins when healthy cells in the bladder lining—most commonly urothelial cells—change and grow out of control, forming a mass called a tumor. Urothelial cells also line the renal pelvis and ureters. Cancer that develops in the renal pelvis and ureters is also considered a type of urothelial cancer and is often called upper tract urothelial cancer. In most cases, it is treated in much the same way as bladder cancer and is described in this guide. A tumor can be cancerous or benign. A cancerous tumor is malignant, meaning it can grow and spread to other parts of the body. A benign tumor means the tumor can grow but will not spread. Benign bladder tumors are very rare.         Signs and symptoms Blood or blood clots in the urine Pain or burning sensation during urination Frequent urination Feeling the need to urinate...
