Whether cervical cancer radiotherapy is tolerated by the elderly needs to be judged comprehensively by their physical fitness and sensitivity to radiation. Radiotherapy for cervical cancer may lead to bone marrow suppression, gastrointestinal adverse reaction, damage of skin and mucous membrane in the radiation area and so on. If there is bone marrow suppression, it is easy to lead to low white blood cells, easy to have low immunity, and trigger infections and so on. At the same time, if there is a decrease in platelets, it may also lead to bleeding of mucous membranes. Gastrointestinal toxicity side effects may be manifested as vomiting, diarrhea and so on. Therefore, if the elderly are already in poor physical condition, as well as more sensitive to radiation, then it is easy to lead to not be able to withstand the reaction brought about by radiotherapy. Specific cases need to be treated according to the doctor’s assessment and medical advice.
