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.
How the disease spread. The way which Myxomatosis spread is a amazing story. It was first discovered in 1896, in lab rabbits from Spain.Many believe the illness come from Brazil, but I can assure you that this is wrong.o prevent a rabbit from contracting Mixi is fairly simple. The most affective way is to have the rabbit vaccinated every 6 or 12 months, depending on the risk in the area. Vaccination is not a guarantee; the rabbit is still at risk but is far less likely to contract the illness and will be more likely to recover.
