After treatment, watch for reactions at the treatment site (such as pain, swelling, or skin changes) and follow up with your care team as scheduled. Most discomfort improves over time, but you should contact your care team promptly if anything seems abnormal.
What are common general reactions after treatment?
According to the American Cancer Society (ACS), most side effects do not last long, but actual reactions vary by hyperthermia type:
- Local hyperthermia: the treatment site may show pain, swelling, burning sensation, or blistering
- Whole-body or regional hyperthermia: nausea, vomiting, or diarrhea may occur
See Common Side Effects for details.
When should you contact your care team promptly?
- Unusual redness, discharge, or worsening pain at the treatment site
- Fever or other signs of infection
- Symptoms that differ significantly from what your care team described as expected
The above is general guidance only and cannot replace individualized education from your care team. Actual care priorities should follow the treatment type, site, and your care team’s instructions.
How long until you can resume daily activities after treatment?
Recovery time varies by hyperthermia type, treatment site, and individual condition; some local treatments allow faster recovery, while whole-body or regional treatments may require a longer observation period. Actual recovery time should follow your care team's individual assessment.
