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.
With testicular cancer, abnormal cells in the testicles divide uncontrollably and form a cancerous tumor. If the cancer isn't treated, those cells can break off and spread to other parts of the body. Testicular cancer is not particularly common. There are about 8,300 new cases a year. And about 350 men die each year from this cancer. But while some men are more likely to get it than others, it's possible for any young man to get the disease.
