Updated 04/08/2025
If you have cancer and are unable to work due to your condition, you may be eligible for Social Security Disability Insurance (SSDI) benefits. Applying for SSDI can be a lengthy and complex process, but understanding the steps involved and knowing how cancer fits into the Social Security Administration’s (SSA) criteria can help you navigate the application more smoothly. Here’s a detailed guide on how to apply for SSDI benefits if you have cancer.
Find out if you qualify for SSDI benefits. Pre-qualify in 60 seconds for up to $4,018 per month and 12 months back pay.
Please answer a few questions to help us determine your eligibility.
Understand SSDI Eligibility for Cancer
Before you apply for SSDI, it’s important to know if you meet the SSA’s eligibility criteria. The SSA will evaluate your ability to work based on the severity of your condition, how long you’ve worked, and whether your cancer qualifies as a disability under their rules.
To be eligible for SSDI, you must meet the following criteria:
- Work History: You must have worked a certain number of years and paid into the Social Security system through payroll taxes.
- Disability Definition: Your cancer must prevent you from engaging in substantial gainful activity (SGA) for at least 12 months or result in death. The SSA must determine that your cancer significantly limits your ability to perform daily work tasks.
Determine if Your Cancer is Listed in the SSA’s Blue Book
The SSA’s Blue Book is a guide that lists medical conditions that qualify for SSDI benefits. Cancer is specifically listed in the Blue Book under Malignant Neoplastic Diseases. This means that if you have cancer, you may qualify for SSDI benefits, depending on the type, stage, and how it affects your ability to work.
The SSA uses the following criteria to determine if your cancer qualifies:
- Cancer type: Certain types of cancer, such as lung cancer, breast cancer, colon cancer, or leukemia, may qualify more quickly if they are in an advanced stage.
- Cancer stage: The SSA will consider whether your cancer is in a metastatic stage (spread to other parts of the body) or if it is causing functional limitations.
- Treatment side effects: The side effects of cancer treatment (e.g., chemotherapy, radiation) may also be factored into your eligibility. If these treatments prevent you from working or cause severe symptoms, they could support your SSDI application.
Gather Necessary Medical Documentation
When applying for SSDI with cancer, the most critical part of your application is your medical evidence. The SSA will need strong, detailed medical documentation to assess your condition and its impact on your ability to work. Here’s what you should gather:
- Cancer Diagnosis: Medical records that confirm your diagnosis, including biopsy reports and imaging results (e.g., CT scans, MRIs).
- Treatment Records: Detailed records of your cancer treatments, including chemotherapy, radiation therapy, surgeries, and medications.
- Doctor’s Opinions: Letters or statements from your oncologist or other specialists explaining how your cancer affects your ability to work.
- Functional Limitations: Documentation on how your cancer and its treatments limit your physical or mental abilities (e.g., fatigue, pain, difficulty concentrating, mobility issues).
Complete the SSDI Application
Once you’ve gathered all necessary documentation, you can begin the application process. There are two ways to apply for SSDI benefits:
- Online Application: The easiest and quickest way is through the SSA’s website at www.ssa.gov. Follow the online prompts and be sure to answer all questions accurately and completely.
- In-Person or Phone Application: If you prefer, you can apply in person at your local SSA office or by calling 1-800-772-1213 to schedule an appointment.
Be Detailed and Accurate in Your Application
When filling out your application, it’s important to be thorough and honest. Provide the SSA with complete information about your cancer diagnosis, treatment history, and how your condition impacts your ability to work.
Some tips for a successful application:
- Describe how your cancer affects your ability to work: Be specific about how your cancer and treatments make it difficult to perform job tasks. For example, if you experience fatigue, pain, or weakness, explain how these symptoms limit your ability to work full-time.
- Include all medical records: Submit comprehensive medical documentation to support your claim. Missing or incomplete records can delay the process or result in a denial.
- Provide work history information: Make sure to include detailed information about your past work, including job titles, duties, and the dates you worked.
Understand the SSDI Approval Process
After you submit your application, the SSA will review it and determine whether you meet the qualifications for SSDI benefits. The process typically takes 3 to 5 months, but it can take longer, especially if additional information or documentation is needed.
If your initial application is denied (which is common), you can appeal the decision. The appeals process involves several stages, including reconsideration, a hearing before an Administrative Law Judge (ALJ), and further appeals if necessary.
Be Prepared for a Possible Denial
While cancer is a serious condition that can qualify you for SSDI benefits, many applicants are initially denied. The denial is not necessarily because your cancer isn’t severe enough, but because the SSA didn’t have enough medical evidence or didn’t see how it affects your ability to work.

If you are denied, you can appeal the decision. It’s important to consult with a
Social Security Disability attorney to help you navigate the appeals process and improve your chances of a successful outcome.
