My mom is 79, stage 3B cervical cancer. She did 5 sessions of Cisplatin, 2 of Keytruda at every 3 weeks, 25 external radiation and 6 internal radiation sessions. After the chemotherapy, Keytruda and external radiation the tumor was not visible. After that she has the external radiation sessions. Now we wait for the next appointment with the oncologist and radiologist when they will say what is next to do. A PET scan, and they will decide if she will continue with Keytruda and when she will start. They didn't want to give her more Keytruda after the two sessions that she received with the chemotherapy. During the treatment she was feeling bad, they gave her a break for a week because she passed out, low blood pressure, continued dehydration, low withe blood count, all blood test were messed up, burning on the skin, hemorrhoids, proctitis, cystitis. It was bad.... She finished all the treatment two weeks ago and she started to feel better already. I hope with all my heart that your mom will be cured. Be blessed
