What is a Cancer Doctor Called? Oncolgist’s Explained!

We’re going to start with a little cancer 101. For those of you who are new to cancer, we are going to talk about what a cancer doctor is called. This post is geared toward those who are new to cancer or curious. 

I wanted to change up what I normally talk about for helping survivors. But I think helping new patients and people who are new to the cancer experience is also really important. 

So what do you call a cancer doctor?

Well, a cancer doctor is called an Oncologist, and they practice Oncology, which is the study of cancer. This is really a simple explanation. I’m going to go over six main types of oncology experts who handle different aspects of oncology. By the end of this post, you’ll have a better, clearer picture of what they do and why. 


A Medical Oncologist and Surgical Oncologist

OK,  a medical oncologist treats cancer using chemotherapy, targeted therapy, immunotherapy, and other medications. Also, they are the ones who prescribe the first bit of your treatment. They also work hand in hand with the second oncologist, a surgical oncologist. 

Now, surgical oncologists use surgery to remove tumors, and they help with performing biopsies. They are critical in helping diagnose and stage your cancer and figure out what kind of treatments you’re going to need as you move forward.

A Radiation Oncologist

Now the third one is a radiation oncologist, and a radiation oncologist treats cancer using radiation therapy. So if you have to have a tumor that needs radiation to be part of treatment, then you will see a radiation oncologist also. Now, these three can work hand in hand together with the type of therapy and treatment that you need moving forward. They work a lot more hand in hand than the rest of them. I call them the Big Three.

The next three are also really important, and they all can work together depending on what kind of cancer you have. 

A Gynecologic Oncologist

The fourth one is a Gynecologic Oncologist. Now they treat gynecologic cancers like uterine, ovarian, and cervical. It’s more of a female oncologist who helps with the feminine and reproductive areas of a woman’s body.

A Pediatric Oncologist

The fifth one is a pediatric oncologist. Now, pediatric oncologists deal with children and childhood cancers. They will also deal with adult cancer patients if the cancer is very similar to what certain children deal with. So it all kind of depends. But mostly pediatric oncologists deal with kids. A touchy subject because none of us ever wants to see a child go through cancer. Cause for those of us that have been through it and are survivors, and that’s a really tough pill to swallow. 

A Hematologist-Oncologist (Blood)

The sixth one is a Hematologist-Oncologist. Now they deal with diagnosis and treatments for blood cancers like leukemia, lymphoma, and Myeloma. And they are just specialty oncologists for those fields in themselves. Some medical oncologists also study Hematology(Blood) to broaden their education.

These are the six different types of oncologists. And they mostly do everything in the cancer world. This is how it is broken down from my understanding and experience from talking to different oncology departments. 

In my case, I have a hematologist. I also dealt with a medical oncologist and a surgical oncologist through my lymphoma. Having had lymph nodes removed, multiple biopsies, and different ports placed, you can see why you may deal with multiple oncology professionals throughout your experience. Their job is to really explain the diagnosis and staging of your cancer. 

So, what do they do?

They’re going to help give you a better understanding of what it is that you might be up against. 

They should also review all the different treatment options for you. Because there is more than one for each type of cancer you’re dealing with. There are a lot of different treatment options. And oncology is based on Western medicine treatment options.

Don’t forget the alternatives…

And then some treatments and options aren’t suggested. Some are through Eastern medicine. And some are based on people’s personal experience. As a new patient or potential patient, you should, by all means, start informing yourself about everything that is out there. Here is one example… Hoxsey Bio-Medical Center in Tijuana, Mexico. Hoxsey is my alternative to long-term chemotherapy.

Please remember, Oncology’s job is to help deal with symptoms and side effects management. If you’re dealing with a lot of pain or dealing with one of my side effects, they should be able to help you deal with those side effects that come along with chemotherapy and radiation. Even the surgical side of cancer. 

So those are the six different types of oncologists and what their job is to do.

Todd W Franzen


I am a two-time Hodgkin's lymphoma survivor with 17 years of documented cancer survivorship experience that spans multiple treatment eras. My journey began in November 2009 with a Stage 4B diagnosis at age 33, and continued through recurrence and treatment in 2019-2021. This rare longitudinal perspective—living through two complete treatment cycles a decade apart—gives me comparative insight into cancer care evolution that no single medical professional can replicate.

MY TREATMENT EXPERIENCE

First Treatment Cycle (2009-2010)
• 12 infusions of ABVD Chemotherapy over 6 months
• 2 infusions of ICE Chemotherapy (4-day infusions)
• 1 infusion of BEAM Chemotherapy
• 1 Autologous Stem-Cell Transplant
• 8 PET Scans
• 6 CT Scans

Second Treatment Cycle (2019-2021)
• 2 infusions of Brentuximab and Bendamustine
(Severe allergic reaction to Brentuximab — hives)
• 25 rounds of Radiation to Mediastinum (46RAD combined)
• 4 infusions of Keytruda Immunotherapy
• 2 infusions of IGEV Chemotherapy (5-day infusions)
• 1 Total Body Radiation (2RAD)
• 1 Sibling Allogeneic Stem-Cell Transplant
• 6 PET Scans
• 6 CT Scans

COMPARATIVE EXPERTISE

Surviving two stem-cell transplants—one autologous, one sibling allogeneic—across different decades of cancer treatment has given me firsthand experience with nearly every major modality in lymphoma care: combination chemotherapy, salvage chemotherapy, immunotherapy, radiation protocols, and both types of stem-cell transplantation. I've experienced treatment side effects from the "standard" ABVD era through the modern immunotherapy period.

This comparative expertise matters for survivors. Treatment protocols in 2009 looked very different from 2019, and the long-term survivorship implications are still emerging. Doctors treat; survivors live with the aftermath. I've done both—twice.

WHAT I WRITE ABOUT

Cancer survivorship doesn't end when treatment stops—it's when the real reconstruction begins. My blog covers:
• Practical survivorship (relationships, careers, identity)
• Treatment experience insights (what they don't tell you)
