Among the many reasons I chose the specialty of medical oncology is that cancer can present anywhere in the body, manifest any symptom, affect anyone, and its clinical course often presents conundrums for our inner Sherlock Holmes or Dr. House. “The Weekly Check-Up” radio show launched the year I retired from my clinical practice. I didn't realize how important a role it would play in my continued sanity as I navigated the next phase of my professional career. Like my cancer practice, “The Weekly Check-Up” callers cover the entirety of human anatomy and physiology, and there is always a puzzle to solve. This episode features a diverse set of topics that keep the radio show and these podcasts both entertaining and informative. - Dr. Bruce Feinberg, host of “The Weekly Check-Up Podcast.”

Medical historians endlessly debate the greatest medical advancements. Among them are vaccination credited to Jenner in 1796; anesthesia credited to Crawford-Long in 1842; antibiotics with Fleming’s discovery of penicillin in 1928; and X-rays credited to the Curies and Roentgen in 1895. Then you have organ transplantation, public health improvements, insulin, the microscope, germ theory, and the discovery of DNA by Watson and Crick. “The Weekly Check-Up Podcast’s” list concludes with computerized tomography, the fiber optic endoscope, and percutaneous coronary intervention or PCI. Together these discoveries resulted in a quantum leap in disease prevention, diagnosis, and treatment, as we'll hear on this episode.

The use of sound or acoustic energy in medicine has evolved from the ancient diagnostic method used by ⁠Hippocrates by placing his ear to the chest. However, we had to wait 2,000 years for the invention of the ⁠stethoscope⁠. Today, acoustic energy is used in diagnostic imaging called ultrasound that has revolutionized obstetrics and cardiology, while therapeutic applications of sound have resulted in shockwave lithotripsy to break up kidney stones, destroy tumors. This episode explores new uses of sound energy.
