Is numbness a common side effect of kidney cancer treatment?

Yes numbness or tingling (often called peripheral neuropathy) can happen with several cancer treatments used for kidney cancer, though it depends on the exact therapy you received. Some chemotherapy drugs, certain targeted agents, and immunotherapies can affect nerves in the hands and feet, leading to numbness, tingling, burning, or pain; symptoms may be short-lived or sometimes persist. ^{[1] [2] [3] [4]} Immunotherapy can also be associated with nerve-related side effects, and your care team may adjust treatment or prescribe medicines to relieve symptoms. ^{[5] [2]}

Why numbness happens

• Chemotherapy-induced nerve effects: Several chemotherapy classes can damage peripheral nerves in a dose-related, cumulative pattern, most often starting in fingers and toes and potentially spreading in a “glove-and-stocking” pattern. ^{[3] [4]} Symptoms may appear after weeks of treatment and can sometimes worsen for a period even after stopping therapy (“coasting”). ^[4]
• Immunotherapy-related neuropathy: Immune checkpoint inhibitors may, less commonly, trigger nerve inflammation that feels like numbness or tingling; clinicians monitor for these immune-related adverse events and manage them according to severity. ^{[2] [6]}
• Other agents: Some newer antibody–drug conjugates and targeted therapies have reported neuropathy risk, and incidence varies by drug and exposure. ^{[2] [7]}

What it feels like and when it starts

• Typical sensations include numbness, “pins and needles,” burning, or pain in toes and fingers; sometimes there’s weakness or balance trouble. ^{[8] [3]}
• Onset can be early or delayed, but it commonly develops after several weeks and relates to how long and how much treatment was given. ^[4]
• For some, symptoms ease after dose changes or stopping the drug; for others, they can last months or longer. ^{[1] [4]}

How to manage numbness safely

Talk to your oncology team early if symptoms start or worsen they can adjust dosing, pause treatment, or add supportive medicines to protect function. ^{[1] [4]}

Self-care and prevention tips

• Exercise regularly to support nerve health and balance. ^{[1] [5]}
• Avoid alcohol and stop smoking, which can worsen nerve damage. ^{[5] [1]}
• Keep hands and feet warm; wear gloves and warm socks in cold weather. ^{[5] [1]}
• Protect from burns: test water temperature with your elbow; use oven mitts and pot holders. ^[9]
• Fall prevention: keep rooms well lit and uncluttered; wear supportive, non-slip footwear. ^[9]
• Foot and skin care: check daily for blisters or injuries if sensation is reduced. ^[10]

Medical treatments your team may consider

• Dose modification or temporary treatment break for worsening neuropathy. ^{[1] [4]}
• Medications for neuropathic pain and tingling may be prescribed to ease discomfort. ^{[5] [8]}
• Physical therapy or occupational therapy to help with balance, strength, and daily tasks. ^[8]
• For suspected immune-related neuropathy, prompt evaluation and guideline-based management (which can include steroids or other immune-modulating strategies depending on severity). ^{[2] [6]}

When to call your care team urgently

• Rapidly worsening numbness, new weakness, trouble with balance or walking, severe pain, or loss of function (e.g., difficulty buttoning, holding objects). ^[10]
• New symptoms suggestive of immune-related nerve issues during immunotherapy (even if mild), as early treatment can prevent progression. ^[6]

Outlook

Many people experience improvement over time, especially with early recognition and dose adjustments, though recovery can vary and sometimes takes months. ^{[1] [4]} Building a routine around exercise, safety, and skin protection while working with your team on medications and therapy can meaningfully reduce symptoms and protect quality of life. ^{[5] [8]}

Quick reference: common causes and actions

Potential cause	How common/pattern	What helps
Chemotherapy-related neuropathy	Often dose-related and cumulative; starts in toes/fingers; may “coast” after stopping	Dose changes or pauses; exercise; avoid alcohol; symptom medicines; safety measures
Immunotherapy-related neuropathy	Less common; can cause numbness/tingling in hands/feet	Report early; medicines to ease symptoms; immune-related adverse event management if confirmed
Other anticancer agents (e.g., some ADCs)	Incidence varies; often sensory-predominant	Monitoring; dose adjustments; supportive care
