Cancer is one of the most challenging diagnoses a person can face. But for many patients, the side effects of chemotherapy and other treatments can be just as disabling as the disease itself. If cancer or its treatment has left you unable to work, you may qualify for Social Security Disability Insurance (SSDI).
Here’s how to pursue SSDI benefits based on debilitating treatment side effects—and what evidence you’ll need to support your claim.
Can You Qualify for SSDI Based on Treatment Side Effects?
Yes. While SSDI benefits are often associated with the underlying medical condition (like cancer), the Social Security Administration (SSA) also considers how treatments affect your ability to function. Chemotherapy, radiation, immunotherapy, and surgery can lead to serious, long-lasting side effects that interfere with daily life and employment.
Common Debilitating Side Effects
- Extreme fatigue and weakness
- Chronic nausea, vomiting, or loss of appetite
- Neuropathy (numbness or pain in hands and feet)
- Cognitive issues (“chemo brain”)
- Susceptibility to infection
- Organ damage (heart, lungs, kidneys)
If these effects are severe enough and expected to last 12 months or longer—or result in death—they can qualify you for SSDI.
When Cancer Automatically Qualifies
Some cancers are considered “Compassionate Allowances,” meaning SSA fast-tracks those applications because they are clearly disabling. Examples include:
- Pancreatic cancer
- Glioblastoma
- Small cell lung cancer
- Inflammatory breast cancer
But even if your cancer isn’t on this list, or is treatable/curable, you may still qualify based on the functional impact of treatment.
Building a Strong SSDI Application
Your goal is to show the SSA that your treatment side effects make it impossible to work consistently or reliably. Here’s how to build a compelling claim.
1. Document All Side Effects Thoroughly
Keep detailed records of:
- When side effects began and how long they’ve lasted
- How they interfere with basic tasks (walking, concentrating, standing, etc.)
- Medications taken to manage symptoms and their effects
- Days missed from work due to treatment or side effects
2. Get Strong Medical Support
Ask your oncologist or treating physician to:
- Submit medical records to SSA
- Write a detailed statement about how treatment limits your ability to work
- Complete a Residual Functional Capacity (RFC) assessment, if possible
Medical opinions that describe your symptoms in work-related terms (e.g., can’t lift more than 10 pounds, can’t sit/stand for long periods, needs frequent breaks) can be especially persuasive.
3. Include Mental and Emotional Impacts
Cancer and its treatment often take a toll on mental health. If you’re also struggling with depression, anxiety, PTSD, or cognitive issues, make sure these are documented and treated. SSA will consider all impairments when evaluating your case.
What If You’re Still Undergoing Treatment?
You don’t need to wait until treatment ends to apply. If your symptoms and side effects have already lasted—or are expected to last—12 months or longer, you can begin the application process now.
And if your condition worsens, you can submit updated medical evidence at any time during the review or appeals process.
