Does advanced stomach cancer hurt every day?

Due to the invasion of nerves and side effects of treatment, patients with advanced stage of gastric cancer may have daily pain, which can be treated symptomatically by taking painkillers.
Gastric cancer is a common malignant tumor of the upper digestive system, and it can be accompanied by distant metastasis when the disease develops to the late stage. At this time, due to the invasion of nerves by cancer tissues, side effects of radiotherapy and other treatments, and mental stress, patients with advanced stage of gastric cancer may suffer from daily pain.
At this time, in addition to active surgery, radiotherapy and other treatments for primary and metastatic foci, patients are often given symptomatic treatments of painkillers, such as ibuprofen, fentanyl, morphine, etc. Note that they should be applied under the guidance of doctors, and do not use drugs without authorization.
