Ever since scientists sequenced the first DNA strand as part of the Human Genomic Project in the early part of the 21st century, our understanding of the role genes play in our health, and disease, has revolutionized the field of medicine. This is especially true of cancer care. In this episode of Focus on Cancer, the first in a two-part series, Pat Basu, MD, MBA, President & CEO of Cancer Treatment Centers of America® (CTCA), and his guest, Maurie Markman, MD, President of Medicine & Science at CTCA®, discuss pharmacogenomics, a burgeoning field that studies the role genetic variants play in how the body responds to medication.
