(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.
Testicular cancer is rare, accounting for about 1% of all male cancers. However, testicular cancer is the most common form of cancer in men ages 15-35. Every year, in the U.S., an estimated 8500 men are diagnosed with testicular cancer and 350 die from the disease. That averages to every hour of every day some man hears, âYou have testicular cancer.â. Testicular cancer is one of the most treatable cancers, especially if caught early. If caught at an early stage, before it has spread, the survival rate is almost 100% but if caught at a late stage the rate drops to 80%.
