Years after breast cancer surgery, the fingers feel like tingling for a while, and the index finger can not be gripped, which may be caused by postoperative sequelae, metastasis of cancer cells after surgery, proliferation of cancer cells and other factors. 1. Postoperative sequelae: Breast cancer surgery is relatively traumatic, and improper operation may injure the nerves and lead to nerve damage. Symptoms may involve arms, fingers and so on. 2. Post-operative metastasis of cancer cells: the condition may recur again after breast cancer surgery, and the cancer cells may metastasize through the distal end, including joints and bones, etc., thus causing pain like pinprick in the fingers, which makes it impossible to move normally. 3. Proliferation of cancer cells: after breast cancer surgery, cancer cells are proliferating, which may involve several organs, including bones and joints, and easily cause pain, mainly like pinprick, cut, dull pain, etc. Meanwhile, factors other than breast cancer, such as the pain in the fingers, may cause pain in the fingers, which is like pinprick and cannot move normally. Meanwhile, factors other than breast cancer, such as cervical spondylosis, nerve injury, craniocerebral disorders, can cause such symptoms, which need to be carefully identified. After breast cancer surgery for many years like pins and needles, it is recommended to consult a doctor in time, after a clear diagnosis and standardized treatment under the guidance of the doctor.
