Until today, most diseases were treated with standardised therapy options that did not allow for individual variance. Customization of healthcare is now possible because of technological advancements in the field. Today, we'll look at how healthcare can be customised for cancer management. To manage a health issue, personalised medicine involves the use of specific medicines or drugs based on a patient's molecular analysis. The molecular foundation of any disease in an individual is defined by genomics. Precision medicine is a branch of medicine that focuses on disease treatment and prevention depending on a person's lifestyle, genetic composition, and environment. This treatment is founded on the notion that "every patient is unique." Precision medicine adds specifics to each, such as targeted therapy and which pharmaceuticals will work best with other drugs, and so on. Drugs in the trial phase for precision medicine are still being studied. Patients having a genetic mutation can participate in these clinical studies, and a medication treatment can be tested on them.
