Cancer research is an area of biology where growth curve analysis plays an important role. In many types of cancer, the rate at which tumors shrink following chemotherapy is related to the rate of tumor growth before treatment. ...

WebCancer cells, particularly those arising from the bone marrow or lymphatic system, may have a short generation time, and there usually are a smaller percentage of cells in G0 (resting phase). Initial exponential tumor growth is followed by a plateau phase when cell death nearly equals the rate of formation of daughter cells. WebThis pattern generalizes for any constant fractional increase: if it takes 40 hours for 10 3 cells to grow into 10 4 cells (an increase by a factor of 10), it will take 40 hours for 10 7 cells to grow into 10 8 cells.
