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 simple version
This page is for anyone who wants to know what raises the chance of kidney cancer. 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.
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
- Does my personal or family history suggest genetic counseling could help?
- Should my close relatives know about my diagnosis, so they can think about their own risk?
- What, if anything, makes sense to change now, given my situation?
- What follow-up schedule fits my risk factors?

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.

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.
