(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.
Today, for localized tumors that have not spread (Stage 1), 90 percent of patients will live another five years, and half will live more than 10 years. In about six percent to 10 percent of all breast cancer patients, the cancer has already spread to a second location by the time it is diagnosed (Stage 2). Frightening Diagnosis. Stage 4 cancer is a condition in which cancer has spread (metastasized) from its original location to other organs in the body. Metastatic cancer is what claimed the life of Elizabeth Edwards nearly four years after it was first diagnosed.
