#radiation therapy, #anticancer therapy, #cancer treatment, #lack of energy, #lethargy, #persistent fatigue, #dry cough, #frequent mild cough, #persistent cough, #loose stool, #watery diarrhea, #frequent bowel movements

Radiation therapy is a treatment that uses high-energy radiation to damage the DNA of cancer cells, which stops their growth and ultimately destroys them. Some normal cells are also damaged, but they usually recover more quickly than cancer cells and may return to normal function after treatment ends.
