An experimental personalized mRNA vaccine in combination with the immunotherapy Keytruda reduced the risk of recurrence or death from melanoma cancer in patients who had already had surgery, Moderna and Merck said Dec. 13, 2022.  This is a big breakthrough for mRNA being used for cancer!

Precision medicine has already created over 100 targeted therapies for cancer and other illness such as sickle cell, hemophilia and thalassemia. Also, precision medicine is helping to create unique therapies for minority populations who historically were underrepresented in clinical trials of traditional drugs, making such drugs less effective. Cancer death rates for some cancers can be over 2 times higher in minorities vs. whites due to ineffective prevention, diagnosis, and treatments.

Precision medicine is the revolutionary approach to medicine seeking  to understand, diagnose, and treat each unique person's illness. It seeks to understand how a person's genetic code interacts with diseases, nutrition, and environment.  Precision medicine follows the era of blockbuster one-size-fits-all drugs working in only 50-70% of patients, typically.

In the future, researchers predict that cancer treatments will be specifically tailored to a patient's unique genetic code. This will target specific cancers instead of the one-size-fits-all treatments of today's chemotherapy. Artificial intelligence (AI) may identify circulating tumor cells during the onset of cancer and be used to create personalized cancer therapy to stimulates the immune system to fight off cancer.

Targeted molecular treatment is a type of precision medicine ("PM"), transforming cancer treatments in particular. Patients with the same disease should not be treated the same. PM can predict how effective or what side effects a patient will have to a drug. E.g. PM drugs for Myelogenous Leukemia have turned this formerly deadly cancer into just a chronic illness where patients can live normal lifespans.
