hello @tongxiaozhi - welcome to mayo connect. I'm sorry to learn of your mother's diagnosis. it sounds like you are being considerate of her by spacing out the news on her health. my parents also had cancer, so I can empathize with your position. from the perspective of the patient, whatever treatment her doctor will suggest will not be easy, so it's important that your mom is part of that decision making process. one thing you can ask about is what supportive care options are available for her during treatment (acupuncture helped my mother with nausea during chemotherapy). has your mom had a brain MRI yet?
