Cancer patients don't usually have just one symptom related to cancer treatment, often they have several that cluster together.
Examples of symptom clusters include:
- fatigue, pain, sleep disturbances, cognitive difficulties, depression
- nausea, vomiting, anorexia, fatigue
NCI supports research to understand and relieve symptom clusters.
