(Be ready to show students the 19-slide How Does an Ultrasonic Sensor Work? Presentation, a Microsoft Â® PowerPoint Â® file, to teach the lesson. In advance, make copies of the Ultrasonic Sensor Pre-Quiz and Ultrasonic Sensor Post-Quiz, one each per student, provided as attachments and slides.
Progression. Testicular cancer (specifically, germ cell tumors) is an aggressive cancer, doubling in size every 10 to 30 days. If not treated, testicular cancer can spread via the lymphatic pathways.The lymph glands around the aorta and the vena cava at the level of the kidneys are the first to be involved.n advanced cases it can spread to the lungs, liver, brain, bone, kidney, adrenal gland, and spleen. Without treatment, a testicular cancer patient will die on average 2-3 years from time of diagnosis.
Stage is a term used in cancer treatment to describe the extent of the cancer 's spread. The stages of pancreatic cancer are used to guide treatment and to classify patients for clinical trials. The stages of pancreatic cancer are: 1  Stage 0: No spread.2  Pancreatic cancer is limited to a single layer of cells in the pancreas. 3  The pancreatic cancer is not visible on imaging tests or even to the naked eye. 4  Stage I: Local growth. Stage II: Local spread. 2  Pancreatic cancer has grown outside the pancreas, or has spread to nearby lymph nodes. 3  Stage III: Wider spread. 4  The tumor has expanded into nearby major blood vessels or nerves but has not metastasized. 5  Stage IV: Confirmed spread. 6  Pancreatic cancer has spread to distant organs.
