Cancer pain can stem from the cancer itself, such as a tumor pressing on nerves, or from its treatments, like chemotherapy or surgery. This pain can feel aching, throbbing, or burning, and its diagnosis often requires a detailed patient history, physical examination, and imaging tests. Treatment options range from conservative methods like over-the-counter pain relievers and complementary therapies to interventional procedures like nerve blocks, with the main goal of improving the patient’s comfort and quality of life.
