What Causes Nausea and Vomiting in Cancer Patients?
Nausea and vomiting in cancer patients can be caused by various factors. One of the primary causes is the cancer treatment itself, particularly chemotherapy, which can trigger nausea and vomiting as a side effect. Radiation therapy, especially when directed at the brain or gastrointestinal area, can also lead to these symptoms. Additionally, the cancer itself, especially if it affects the brain, liver, or gastrointestinal tract, can cause nausea and vomiting. Other contributing factors include medications, infections, metabolic imbalances, and psychological factors such as anxiety.
