(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.
When testicular cancer is diagnosed in early stages, meaning the cancer is confined to the testis, the 5-year survival rate is 99%. When the cancer has spread to regional lymph nodes the 5-year survival rate drops to 96%.If the cancer has metastasized (spread) to distant areas the 5-year survival rate is 71%.There are currently more than 195,000 men in the U.S. that are testicular cancer survivors. Testicular cancer accounts for approximately 1% of all cancers in men.f the cancer has metastasized (spread) to distant areas the 5-year survival rate is 71%.
