Personalized cancer medicine is based on research into human genes and cancer genes. These investigations have aided in the development of more effective treatments. They’ve also used genetic data to build cancer diagnostics and prevention methods. Every year, cancer takes the lives of millions of people. Standard treatments, such as chemotherapy or radiation, are only effective in a small percentage of patients because of disease heterogeneity. Tumors can have a variety of genetic origins and may express various proteins in different patients. Other methods of cancer treatment may have more side effects than personalized cancer medicine. This is due to the fact that it is intended to be more particular. A tailored treatment may have fewer side effects on healthy cells and more on cancer cells.
