Tumor Biology

Tumors grow in a series of steps and cancer cells behave as independent cells, growing without control to form tumors. Hyperplasia meaning that there are too many cells resulting from uncontrolled cell division. These cells appear normal, but often changes have occurred that result in some loss of control of growth. The discovery of tumor stem cells in a range of cancers has created opportunities for researchers to identify these rare cells in both solid tumors and hematologic cancers, as well as to investigate the role of these cells at different stages of disease. The recognition that the cancer cell is in a symbiotic relationship with the tumor microenvironment has created opportunities to study the interactions of cancer cells within the tumor or the host microenvironment
