Applying for SSDI After a Cancer Diagnosis
November 1, 2026
According to a 2024 American Cancer Society study, nearly 60% of working-age cancer survivors experience some form of financial hardship. Cancer treatment can disrupt employment and leave patients struggling to cover everyday expenses alongside mounting medical bills.
“I lost my job, lost my insurance, I had nothing,” says Stephanie Walker, a metastatic breast cancer survivor, interviewed by Susan G. Komen. “I went from having a wonderful life, money, insurance, everything, and overnight to having nothing.”
People like Walker who can’t keep working because of their illness may be eligible for Social Security Disability Insurance (SSDI). These monthly benefits can help pay for medical care and basic living expenses.
Here’s everything you need to know about applying for SSDI.
Who is Eligible?
SSDI eligibility is based on your work history and medical condition. Cancer may qualify based on the type of cancer or because of the effects of cancer and your treatments. You must also have worked and paid Social Security taxes long enough to qualify, usually about 5 of the last 10 years, depending on your age.
Gathering Documents
Review the SSA’s checklist to start gathering everything you’ll need for your application. You will need identification documents, including your birth certificate or proof of citizenship and Social Security number.
Collect all of your medical records that show when your condition began and how it has affected your ability to work, including:
- The dates of and records from all of your examinations and treatments
- All of your medical test results and the ordering doctors
- The medications you take, including who prescribed them and why
Gather proof of all your previous employment and work history for up to the last 15 years, including before you became unable to work. You can access your annual SSA statement online, which outlines your wages and benefits for the years you’ve worked.
Filing Your SSDI
You may apply for SSDI online through the SSA website or by calling 1-800-772-1213 to make an appointment at your local Social Security office. If you have difficulty traveling during cancer treatment, you can request a telephone appointment. Apply as soon as you become unable to work because of your condition. You do not need to have every medical document ready before submitting your application.
Expedited Compassionate Allowance
People diagnosed with certain aggressive or advanced cancers may qualify for faster disability claim processing through the SSA’s Compassionate Allowances program, which flags and approves applicants within days.
Qualifying conditions include pancreatic cancer, small cell lung cancer, acute leukemia, and certain metastatic or inoperable cancers. The SSA automatically identifies eligible applications and prioritizes them for review, sometimes issuing decisions within days rather than months.
Compassionate Allowances does not guarantee approval or eliminate the standard five-month waiting period for SSDI payments. Applicants must still meet Social Security’s eligibility requirements.
Estimating Your Benefits
If your application is approved, your SSDI benefit amount is based on your lifetime average earnings as recognized by Social Security. You can estimate your monthly benefits by creating an account and looking at your Social Security statement at SSA.gov, or by using the online benefits calculator. As of June 2026, Social Security reported an average monthly benefit of $1,635 for disabled workers. Individual payments can be higher or lower.
When Does SSDI Begin?
Once your application is approved, you’ll begin to receive your benefits in the sixth month after the date your disability began. For example, if you applied for disability benefits on January 1, 2026, and the SSA determined your disability began on December 1, 2025, you’d receive your first disability payment in May 2026. Plus, after a 24-month waiting period, anyone eligible for SSDI will also be eligible for Medicare.
What if You are Denied?
According to the SSA, only 32.5 percent of applicants for disability benefits were approved in 2024, the last year for which complete figures are available. If the SSA denies your SSDI application, you may reapply. If your application is denied, you have 60 days to request an appeal, so don’t miss your deadline. Process your appeal online through your SSA.gov account.
“Looking for financial assistance can take up a lot of time and energy,” says Marya Shegog, PhD who works with the Lazarex Cancer Foundation. “That’s a challenge when you are already in a compromised state. Plus, many patients are still working during cancer treatment and they don’t have hours to research all the types of help that might be available.”
Many cases are approved after the appeal process, but you may want to work with a Social Security lawyer who knows the appeals process well.
If you still don’t qualify for SSDI, look into Supplemental Security Income (SSI). This program is based on your income and level of need. It can help people who haven’t worked recently enough or didn’t pay enough into Social Security before their disability to qualify for SSDI.
