How long can a person with brain cancer live by taking morphine

Once cancer pain occurs, patients and their families hope to do everything they can to relieve the pain. So, will the use of morphine to relieve pain during treatment lead to dependence? Anesthesiologists point out that medical use only leads to physical dependence, not mental dependence, so it cannot be considered addiction. So how long can patients with brain cancer survive by taking morphine?

The pain caused by brain cancer is called cancer pain. The pain is particularly severe in patients with bone metastasis and advanced stages. It hurts when sleeping, talking, and moving, and the patient is completely unable to sleep and move normally. Morphine is a common drug used clinically to relieve cancer pain.
Morphine is the main alkaloid in opium and was first isolated from opium in 1806. He used the isolated white powder to experiment on dogs and himself. The dogs fell asleep soon after eating it and could not be awakened by strong stimulation. He himself also fell into a deep sleep after swallowing the powder. Based on this, he named these substances "morphine" after Morpheus, the god of sleep in Greek mythology.
Anti-drug propaganda has been deeply rooted in people's minds. When we see "morphine", the first thing we think of is drugs. We must not touch it, otherwise we will become addicts. Many family members of cancer patients shook their heads when they heard that they had to use morphine to relieve cancer pain: What if they become addicted to morphine? It is a misunderstanding that using morphine to treat brain cancer will make people addicted. Following the doctor's advice and using the drug in a standardized manner will not make people become "addicts."
