Frequently Asked Questions — Dr. Yair Gortzak Answers

1. Does every bone lesion mean cancer?

No.

I wish answering that question were as straightforward as many people think.

A report may describe a lesion, a mass, or an abnormal area in a bone. That still doesn’t tell us what we’re dealing with.

I’ve learned over the years not to make assumptions too early. Sometimes the explanation turns out to be much less alarming than the patient expected after reading the report for the first time.

That’s one reason I prefer looking at the images myself before discussing conclusions.

2. How is treating children different from treating adults?

Quite a bit, actually.

When I operate on an adult, I’m focused on solving the problem that’s in front of me today.

With children, I have to think further ahead. How will the limb grow? What will happen in a few years? Will today’s decision affect mobility later on?

Those questions are part of almost every treatment discussion in pediatric orthopedic oncology.

3. Is a second opinion worth seeking?

I don’t see anything unusual about it.

In fact, many families come specifically because they want another set of experienced eyes looking at the situation.

Sometimes I completely agree with the original recommendation. Sometimes I suggest a different way of approaching the problem.

Either way, people usually leave with a clearer understanding of what they’re facing and why a particular treatment strategy is being proposed.

4. Why do surgeons use 3D planning technologies?

Most of the work happens long before the operation itself.

Patients usually see the day of surgery. What they don’t see is the preparation behind it.

For certain tumors, we can build a detailed three-dimensional model, study the anatomy from different angles, and even prepare a custom implant before entering the operating room.

From my perspective, that level of preparation can make a very real difference during complex procedures.

5. Does sarcoma treatment always begin with surgery?

Not always.

This is one of those questions that sounds simple but rarely has a simple answer.

There are situations where surgery comes first. There are others where medication or radiation therapy may be part of the plan before an operation is even discussed.

That’s why I usually avoid giving a general answer until I understand exactly what type of sarcoma we’re talking about.

6. Does a diagnosis of sarcoma always lead to amputation?

No.

This is probably one of the biggest fears people bring to a consultation.

The reality today is very different from what many imagine. Whenever it can be done safely, the goal is usually to remove the tumor while preserving the limb and maintaining function.

That isn’t possible in every situation, but it is often the first option we explore rather than the last.

7. What happens when cancer spreads to the bones?

The first thing I want to understand is how the affected bone is behaving.

Sometimes the main issue is pain. In other cases, the concern is that the bone has become weak and may fracture.

Only after reviewing the scans and the overall medical picture can we decide what role surgery should play and whether other treatments need to be part of the plan as well.
