The science of Cancer Biology focuses on the study of the different mechanisms and fundamental process of cell growth, the transformation of normal to cancer cells, and the metastasis or spread of these cancer cells to other parts of the body.
As such, it includes the study of how tumor cells develop and grow. It also includes studying how the immune system responds to cancer cells, thus including macrophages and their response to the presence of pathogens and cancer cells. Underlying all these is the inclusion of a study on protein synthesis as it is the process where biological cells build and create new specific proteins in the body.
