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.

The science that includes the study of tumor cells, macrophages and protein synthesis is cell biology.This is because all the three thing given in the question denotes towards the study of cells.

Study of structure and function of cell. Knowing all about the diseases associated with the cell function. Any complication during protein synthesis can led to production of any non functional protein.

Any defect in the cell structure can cause disease and this can be known only when the study of cell structure and function is done.
