Nausea and Vomiting

What Causes Nausea and Vomiting?

Nausea or vomiting may be caused by radiation or chemotherapy treatments for cancer. About 80% of patients treated for cancer experience nausea and vomiting. Although not life-threatening , nausea and vomiting are worrisome side effects that can cause dehydration and choking. It is important to address these side effects quickly to avoid interruption of cancer treatment or a loss of the ability to care for oneself.
