The short answer
Smoking, excess body weight, high blood pressure, and certain genetic conditions raise the risk of kidney cancer. Having a risk factor does not mean kidney cancer is certain, and many people with kidney cancer have no known risk factors.
Smoking is one of the strongest known risk factors for kidney cancer.
Excess body weight and high blood pressure are both linked to higher risk.
Certain inherited conditions, such as von Hippel-Lindau disease, raise risk.
Long-term use of some over-the-counter pain medicines is linked to higher risk.

The full explanation.
The simple version
Kidney cancer, most often a type called renal cell cancer, has several known risk factors. A risk factor is something linked to a higher chance of developing a disease — it does not mean the disease will happen. Some risk factors can be changed. Others, like genetics, cannot.
Having one or more of these risk factors does not mean you will get kidney cancer. Many people with these risk factors never develop it, and some people with none of them do.
Factors linked to daily habits
Smoking tobacco. This is one of the clearest and strongest risk factors for kidney cancer. The longer and more heavily someone has smoked, the higher the risk tends to be. Quitting lowers risk over time, though the benefit may take years to show.
Long-term, heavy use of some pain medicines. Regular, long-term use of certain over-the-counter pain medicines has been linked to higher risk. This is about sustained overuse, not the occasional dose for a headache or sore muscle.
Excess body weight. Carrying excess weight is linked to a higher chance of developing kidney cancer. Researchers are still working out exactly why, but weight is one of the more consistent risk factors identified.
High blood pressure. Having high blood pressure raises risk, separate from any effect of the medicines used to treat it.
Factors you cannot change
Age. Risk rises as people get older.
Family history. Having a close relative with kidney cancer raises your own risk.
Genetic conditions. Certain inherited conditions raise risk substantially. Von Hippel-Lindau disease is one example; it affects several organs and carries a high lifetime risk of kidney tumors. Hereditary papillary renal cancer is another. If kidney cancer runs in your family, or if it was diagnosed at a young age, ask your doctor whether genetic counseling makes sense.
Having risk factors is not your fault
Kidney cancer, like other cancers, comes from a mix of factors that no one fully controls, including genetics and biology working together over many years. If you smoked, carried extra weight, or had high blood pressure, that does not mean you caused your cancer. Plenty of people with these same factors never develop kidney cancer. Some people with none of them do. Blame is not a useful lens here; understanding your own risk factors is.
Why this matters for you
Knowing your risk factors can shape a few practical conversations. If you have a strong family history, ask about genetic counseling and whether testing could affect screening for you or your relatives. If you smoke, ask about resources to help you quit — this helps beyond kidney cancer risk. If high blood pressure or weight are part of the picture, managing them supports your overall health even though no single change guarantees prevention.
What to ask your team
Ask whether your personal or family history suggests genetic counseling could help. Ask whether your close relatives should know about your diagnosis, so they can consider their own risk. Ask what, if anything, makes sense to change now, given your specific situation. Ask what follow-up schedule fits your risk factors going forward.

Common questions
Is smoking really linked to kidney cancer?
Yes. Smoking tobacco is one of the clearest risk factors for kidney cancer. Quitting lowers risk over time, though it may take years for that benefit to show.
Can pain medicine really raise kidney cancer risk?
Long-term, heavy use of some over-the-counter pain medicines has been linked to a higher risk. Occasional use for normal aches and pains is not the concern; it is long-term overuse.
Did my weight or blood pressure cause my kidney cancer?
No single factor causes cancer on its own. Excess weight and high blood pressure are linked to higher risk, but kidney cancer results from a combination of factors, many of which are outside anyone's control.
What are the genetic risk factors?
Some inherited conditions, including von Hippel-Lindau disease and hereditary papillary renal cancer, raise the risk of kidney cancer. A family history of kidney cancer also raises risk.

How this page was created
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. We do not employ clinicians and do not intend to — our work 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 checked line by line against the sources listed on it. That confirms the sources support what the page says. 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.
