The short answer
The National Cancer Institute names autoimmune disease — giving rheumatoid arthritis, psoriasis and Sjögren syndrome as examples — among the risk factors for adult non-Hodgkin lymphoma. This is a link with one family of cancers, not a general rule about every cancer.
NCI's adult non-Hodgkin lymphoma summary lists autoimmune disease as a risk factor, naming rheumatoid arthritis, psoriasis and Sjögren syndrome as examples.
NCI's same risk-factor list includes taking immunosuppressant drugs after an organ transplant.

The whole article, with every detail and caution.
This page is for people living with an autoimmune condition who have heard it can raise cancer risk. It explains what NCI says about the link with lymphoma and what to ask your care team.
Where the connection actually shows up
Maybe you live with lupus, rheumatoid arthritis, psoriasis or Sjögren syndrome. Then you have probably met the claim that autoimmune conditions are tied to cancer. It is not internet folklore. But it is much narrower than the way people repeat it.
The National Cancer Institute's summary on adult non-Hodgkin lymphoma lists autoimmune disease as a risk factor. Its examples are rheumatoid arthritis, psoriasis and Sjögren syndrome. That is a link with lymphoma, which means cancers of the white blood cells. It is not a blanket statement about cancer in general.
What the source does not say
Some websites describe patterns by immune-cell type, or give large risk multiples for single conditions. This page does not repeat those figures. We could not confirm them in the NCI page we opened, so they are left out.
Being on a risk-factor list means the odds differ from average. It does not mean the outcome is decided. If you have a swollen gland that does not go away, tell your rheumatologist or other doctor.
What about the medicines
This part worries people most. It feels like a choice they are making.
NCI's risk-factor list for adult non-Hodgkin lymphoma does include taking immunosuppressant drugs after an organ transplant. These are drugs that damp down the immune system. NCI's discussion of post-transplant lymphoproliferative disorder mentions heart, lung, liver, kidney or pancreas transplants.
Stretching that finding to cover every immune-affecting medicine given for arthritis or psoriasis goes further than this source does. This page will not take that step. Each drug carries its own labeling and its own evidence. Your prescriber can tell you what is on the label of the one you take.
What is reasonable to do
Know the exact name of your condition. "Autoimmune" covers dozens of very different illnesses with very different profiles. The specifics matter far more than the umbrella word.
Keep seeing your specialist. Ongoing rheumatology or dermatology follow-up is exactly where an odd symptom that will not go away gets noticed. That is worth more than any general reading you do.
Ask your care team before changing any treatment out of fear. Trading certain harm for vague comfort is a bad deal.
Bring the question to the person who prescribes for you. Ask straight out whether the benefits of your treatment still outweigh its risks, in your case, this year. That is a normal thing to ask, and a good doctor will welcome it.
Common questions
Does having an autoimmune disease mean I will get lymphoma?
No. Being on a risk-factor list means the odds may differ from average, not that the outcome is decided. Ask your own doctor what it means for you.
Which autoimmune conditions does NCI actually name?
Its adult non-Hodgkin lymphoma page gives rheumatoid arthritis, psoriasis and Sjögren syndrome as examples of autoimmune disease in the risk-factor list.
Is it the disease or the medicine?
NCI's list includes both the autoimmune condition itself and, separately, immunosuppressant drugs taken after an organ transplant. Untangling the two in any individual is not something a general page can do.

Review details and limits
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes, and this is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and then compared with the sources listed on it, looking for statements those sources do not back up. That check is not a sentence-by-sentence record and can miss errors. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
