Hallucinations
What causes hallucinations in patients with cancer?

Some of the possible causes of hallucinations in cancer patients are:

  • medications, especially strong painkillers, such as morphine or Dilaudid;
  • chemical imbalances in the blood, such as high levels of calcium caused by a tumor;
  • infections;
  • tumor that has spread to the brain.

It is important that a patient experiencing hallucinations be seen by a health care provider, so that the cause can be determined.
