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.
The tumor is malignant (cancer) if the cells can grow into (invade) surrounding tissues or spread (metastasize) to distant areas of the body. Breast cancer occurs almost entirely in women, but men can get breast cancer, too. Cells in nearly any part of the body can become cancer and can spread to other areas. To learn more about cancer and how all cancers start and spread, see Cancer Basics. Where breast cancer starts. Breast cancers can start from different parts of the breast.
