Welcome to Season 4 of Tumor Minutes, where we shift our focus to the most complex organ in the human body: the brain.

After a short break due to technical difficulties, we’re back and diving into a brand-new theme: brain diseases. This season will explore conditions that affect memory, movement, cognition, and identity, including Alzheimer’s disease, Parkinson’s disease, epilepsy, strokes, and more.

In this first episode, we focus on Alzheimer’s disease, the most common cause of dementia worldwide. We break down what Alzheimer’s actually is, how it differs from dementia, and what is happening inside the brain as the disease progresses. From the breakdown of memory formation in the hippocampus to the buildup of amyloid plaques and tau tangles, we explore how this condition slowly changes the brain over time.

We also discuss current treatments, ongoing research, and why understanding Alzheimer’s is crucial for the future of neuroscience and medicine.

This is the beginning of a new season, and a deeper look into how the brain shapes who we are.

Lobotomies. The medical procedure that somehow went from “this might help” to “why did we ever think this was okay?”

In this episode of Tumor Minutes, we break down one of the most controversial treatments in medical history. From Nobel Prize-winning beginnings with Egas Moniz to the cross-country “lobotomobile” era of Walter Freeman, this episode covers how lobotomies became popular and why they ultimately failed.

We also talk about real patient outcomes, including the tragic case of Rosemary Kennedy, and explore the ethical questions this chapter of medicine raises.

It is part history lesson, part reality check, and a reminder that “doing something” is not always better than doing nothing.

What happens when there is no time to wait?

In this episode of Tumor Minutes, we dive into the fast-paced, high-stakes world of emergency surgery. From the moment a patient enters the emergency room, medical teams must make rapid decisions under pressure, often with incomplete information. This episode explains how doctors assess urgency, stabilize patients, and determine whether immediate surgery is necessary.

We also explore what happens inside the operating room, why emergency surgeries are often more complex and unpredictable than planned procedures, and how recovery can vary depending on the situation. Since this is Tumor Minutes, we also highlight how tumors can lead to sudden complications that require urgent surgical intervention.

With a mix of clear explanations and a touch of humor, this episode helps you understand not just the “what,” but the “why” behind emergency surgery—and why paying attention to your body’s warning signs matters more than you think.
