Loss of mobility in cancer patients can be attributed to various factors. One significant cause is the direct impact of the tumor on the body's structures. Tumors may invade or compress nerves, bones, or muscles, leading to pain and functional impairment. Additionally, treatments such as chemotherapy, radiation therapy, and surgery can result in side effects that affect mobility. For instance, neuropathy from chemotherapy can cause numbness and weakness, while radiation may lead to fibrosis and joint stiffness.
