Neuropathy During Cancer Treatment

Neuropathy means nerve irritation or damage. It can cause numbness, tingling, burning pain, or weakness. It can also cause balance problems and changes in fine motor tasks. Some cancer treatments are more likely to cause it than others.

This page is a planning aid. It cannot diagnose the cause of a symptom. It cannot replace the instructions from your oncology team.

Nerve symptoms can affect safety, walking, and sleep. They can affect buttoning clothes, writing, falls, and treatment dosing. Reporting early helps the team match symptoms to the treatment plan. It also helps them rule out other causes.

Many treatment side effects are easier to handle when the team hears about them early. If your team already gave you an urgent call plan, use that plan first.

• Where symptoms are: fingers, toes, feet, hands, face, or another area.
• Numbness, tingling, burning, electric pain, weakness, cramps, or balance changes.
• New trouble walking, falls, buttoning, texting, writing, or holding objects.
• Treatment name, dose changes, diabetes history, vitamin issues, alcohol use, or prior nerve problems.
• Whether symptoms are stable, improving, or spreading.

• What is the most likely cause in my situation, and what else needs to be ruled out?
• Which symptoms or changes mean same-day contact for my exact treatment?
• What information should I track before I call or come in?
• Could this affect treatment timing, dose, or supportive medicines?
• Who should I contact after hours, and what should I say first?

The plan may include symptom management and fall-prevention steps. It may include physical or occupational therapy, a medicine review, or dose changes. It may also mean checking for other causes. Ask which symptoms could become long-lasting.

Ask what result or symptom pattern would change the plan. Ask what can be watched, and what should not wait until the next routine visit.

• Do not assume a symptom is "just treatment" without checking the plan your team gave you.
• Do not assume the same symptom means the same thing for every cancer treatment.
• Do not start a new over-the-counter medicine, supplement, or major diet change without asking the care team when symptoms are active.

Most nerve symptoms are reported at the next visit. A few should not wait, because they point to something other than slow chemotherapy nerve damage.

• Call 911 or go to an emergency department if you have trouble breathing or trouble swallowing. NCI lists both as signs that motor nerves are affected.
• Call 911 or go to an emergency department if weakness or numbness comes on suddenly, or affects one side of the face or body.
• Call your care team the same day if you have back pain along with new leg weakness, numbness across both legs, or a change in bladder or bowel control. That pattern can mean pressure on the spinal cord, which is treated urgently.
• Call your care team the same day if you faint, or feel dizzy every time you stand up. Autonomic nerve damage can drop blood pressure.
• Call your care team the same day if numbness or weakness is spreading quickly, or you have burned or cut a numb hand or foot without feeling it.
• Call your care team within a day or two if tingling, numbness, or burning pain is new, or is clearly worse than at the last cycle. NCI says getting these problems diagnosed and treated early is the best way to control them, prevent further damage, and reduce pain and other complications.
• Call your care team within a day or two if you are dropping things, struggling with buttons or a pen, tripping, or losing your balance.
