Abstract: Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive neuromodulation technique that has shown therapeutic potential in treating depression, anxiety, and pain. However, there is a lack of relevant evidence for patients with cancer, thus, whether rTMS is effective and safe for this population remains unclear. By summarizing and analyzing existing studies on the application of rTMS in cancer patients, this review aims to provide new perspective for its use in the comprehensive treatment of cancer and to improve patient’s social function rehabilitation as well as quality of life.
