In most cases the cancer cells form a tumor. Some cancers, like leukemia, rarely form tumors. Instead, these cancer cells involve the blood and blood-forming organs and circulate through other tissues where they grow. Cancer cells often travel to other parts of the body, where they begin to grow and form new tumors that replace normal tissue. This process is called metastasis. It happens when the cancer cells get into the bloodstream or lymph vessels of our body. | National Cancer Institute 100 90 80 70 60 50 40 30 20 10 T 0 10 20 30 40 50 60 0 10 20 30 40 0 10 20 30 40 50 70 80 90 100 50 60 z 70 80 90 100 60 70 80 90 100 2006 Fact Book .
