The Anxiety of Cancer Treatment: What Feels Routine to Your Oncologist May Feel Life-Changing to You

The Anxiety of Cancer Treatment: What Feels Routine to Your Oncologist May Feel Life-Changing to You. After I relapsed, I began printing out questions to ask at my regular appointment with my oncologist. After one appointment that ran for almost an hour, a nurse stopped me on my way out to scold me for taking too much of the oncologist’s time. 

I realized that I was in a very different place, mentally, than my oncologist and nurses were.

When I was diagnosed with multiple myeloma, I quickly realized something. The oncology staff had seen everything before.

  • The nurses calmly inserted IVs.
  • The scheduler casually booked my bone marrow biopsy.
  • The physician ordered another PET scan matter-of-factly.
  • Everyone was professional, caring, and confident.

Meanwhile, I was wondering whether I was going to live long enough to watch my son grow up.

That disconnect isn’t anyone’s fault. Cancer professionals perform these procedures every day. Patients experience them only once—or hope they only experience them once.

Understanding that difference may not eliminate anxiety, but it reminds you that your fears are normal.

Here are many of the moments that commonly produce anxiety during cancer treatment.

Scroll down the page and post a question or a comment if there’s anything you’d like to know about breast cancer.

Good luck,

David Emerson



1. Waiting for Biopsy Results

Perhaps no waiting period feels longer.

Patients often replay every possible outcome in their minds while pathology reports are processed.

The uncertainty can be more stressful than receiving bad news itself.


2. The First Oncology Appointment

Many people remember this appointment forever.

Questions race through your mind:

  • Is this curable?
  • How long do I have?
  • Will I lose my hair?
  • Can I still work?
  • Will I die?

Meanwhile, the physician is gathering information and planning treatment.


3. Hearing “We Need More Tests”

Patients often interpret additional testing as bad news.

Frequently, physicians simply need more information before making recommendations.


4. Bone Marrow Biopsies

For blood cancer patients, few words create more anxiety.

The procedure itself.

The anticipation.

The waiting afterward.

The results.

Every step can be emotionally exhausting.


5. CT Scans, MRI Scans and PET Scans

These become so common that oncologists simply call them “surveillance.”

Patients call them something else:

Scanxiety.

Research has shown that anxiety often increases in the days before imaging, remains elevated while waiting for results, and frequently disrupts sleep.


6. Waiting for Scan Results

The scan may only take twenty minutes.

Waiting three or four days for the report can feel like an eternity.

Many survivors say this is one of the hardest parts of living with cancer.


7. Reading the Radiology Report Before the Doctor Calls

Electronic medical records have changed everything.

Patients often read:

  • “Suspicious lesion”
  • “Cannot exclude malignancy”
  • “Recommend correlation”

…before anyone explains what those phrases actually mean.


8. Watching Blood Counts Fall

Every CBC becomes an emotional event.

Will treatment continue?

Will chemotherapy be delayed?

Do I need a transfusion?


9. Being Told Chemotherapy Is Delayed

Patients often fear:

“The cancer is growing while we wait.”

In reality, treatment delays frequently protect patients from infection or dangerous side effects.


10. Hearing “Your Numbers Look Different”

Even small laboratory changes can create enormous worry.

Physicians may recognize normal biological variation.

Patients often fear recurrence.


11. Starting a New Chemotherapy Drug

Every medication comes with pages of possible side effects.

Most patients immediately wonder:

“Will all of these happen to me?”


12. Infusion Reactions

Many patients spend their first infusion watching every sensation:

Was that a rash?

Am I breathing normally?

Is this an allergic reaction?


13. Port Placement

To clinicians:

A routine outpatient procedure.

To patients:

Another reminder that life has changed dramatically.


14. Stem Cell Collection

For many myeloma and lymphoma patients, this represents crossing an emotional threshold.

Everything suddenly feels very serious.


15. Stem Cell Transplant

Even before admission, anxiety often centers on:

  • isolation
  • infection
  • nausea
  • survival
  • life afterward

16. Hospital Admissions

Every admission creates uncertainty.

Patients wonder:

“What complication happened now?”


17. Emergency Room Visits

A fever during chemotherapy often means immediate evaluation.

Patients frequently fear the worst.


18. Waiting for Insurance Approval

Treatment cannot begin.

Patients feel helpless.

Meanwhile, staff members spend hours navigating prior authorization requirements.


19. Financial Toxicity

Many patients quietly wonder:

Can I afford to survive?

Financial stress often becomes another form of cancer treatment.


20. Follow-up Visits After Treatment Ends

Ironically, anxiety often increases after treatment.

The frequent monitoring disappears.

Patients lose the reassuring routine of seeing their oncology team every week.


21. Every Follow-up Scan

Many survivors never completely lose their scanxiety.

Even decades later, surveillance imaging can trigger insomnia, racing thoughts, and worry about recurrence.


22. Hearing the Word “Recurrence”

Even when recurrence is only one possibility among many, hearing the word can instantly transport patients back to the day they were diagnosed.


23. Clinical Trial Discussions

Patients often wonder:

“Have we run out of options?”

Physicians may see a clinical trial as access to cutting-edge treatment rather than a last resort.


24. Every Unexpected Phone Call From the Cancer Center

Many survivors admit the same reaction.

When the phone rings unexpectedly:

“My cancer must be back.”

Usually, it isn’t.


25. Waiting

Perhaps the greatest anxiety of all.

  • Waiting for appointments.
  • Waiting for pathology.
  • Waiting for laboratory results.
  • Waiting for scans.
  • Waiting for treatment.
  • Waiting to see whether life returns to normal.

One qualitative study captured patients’ feelings in three simple words:

“Waiting sucks.”


What Helped Me

After years of living with multiple myeloma, I eventually realized something important.

My oncologist wasn’t calm because my cancer wasn’t serious.

He was calm because he had walked thousands of patients through similar moments.

That perspective didn’t erase my anxiety, but it reminded me that I wasn’t facing the unknown alone.

Over time, I learned to focus less on every laboratory value and every scan report and more on the aspects of my health I could control: exercise, nutrition, sleep, stress reduction, maintaining social connections, and evidence-based complementary therapies. Those habits gave me a sense of agency during a process that often felt out of my control.

If you’re newly diagnosed, know this:

Feeling anxious does not mean you’re weak.

It means you’re human.

Even the most experienced cancer survivor still feels a racing heart before an important scan.

The goal isn’t to eliminate anxiety completely.

It’s to recognize it, talk about it, and keep moving forward anyway.


PeopleBeatingCancer Evidence Rating

Intervention Evidence Why I Rate It This Way
Preparing questions before appointments High Improves communication and understanding. Supported by oncology communication guidelines.
Discussing anxiety openly with the oncology team High Recommended by ASCO and psycho-oncology experts.
Mindfulness, relaxation, CBT, supportive counseling High Strong evidence for reducing cancer-related anxiety.
Exercise during treatment (as tolerated) Moderate-High Improves mood, fatigue, and quality of life in many studies.
Peer support and survivor mentoring Moderate Consistently helpful in observational studies, though evidence is less robust than formal psychotherapy.
