In short
Kidney cancer forms in the lining of tiny tubes inside the kidneys, which are fist-sized organs on either side of the backbone that filter and clean blood, taking out waste products and making urine. Kidney cancer becomes more likely as people age, and risk factors include smoking, having certain genetic conditions, and misusing pain medicines for a long time. Symptoms may be absent at first but can appear as the cancer grows, including blood in the urine, a lump in the abdomen, weight loss for no reason, pain in the side that does not go away, and loss of appetite. Treatment depends on age, overall health, and how advanced the cancer is, and it might include surgery, chemotherapy, radiation, biologic, or targeted therapies.

Description
You have two kidneys. They are fist-sized organs on either side of your backbone above your waist. The tubes inside filter and clean your blood, taking out waste products and making urine. Kidney cancer forms in the lining of tiny tubes inside your kidneys.
Kidney cancer becomes more likely as you age. Risk factors include smoking, having certain genetic conditions, and misusing pain medicines for a long time.
You may have no symptoms at first. They may appear as the cancer grows. See your health care provider if you notice:
- Blood in your urine
- A lump in your abdomen
- Weight loss for no reason
- Pain in your side that does not go away
- Loss of appetite
Tests to diagnose kidney cancer include blood, urine, and imaging tests. You may also have a biopsy.
Treatment depends on your age, your overall health and how advanced the cancer is. It might include surgery, chemotherapy, or radiation, biologic, or targeted therapies. Biologic therapy boosts your body's own ability to fight cancer. Targeted therapy uses drugs or other substances that attack specific cancer cells with less harm to normal cells.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.
Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
