Cancer treatments are designed to kill or inhibit the growth of cancer cells. However, they can also affect healthy cells, including neurons. Chemotherapy-induced neurotoxicity is common and can manifest as peripheral neuropathy, affecting the extremities like hands and feet, or central neurotoxicity, impacting the brain and spinal cord. Radiation therapy, especially when directed at the head or neck, can also lead to neurotoxic effects by damaging nerve tissues directly.
