Patient: It was discovered a year ago and I didn’t care about it at that time, so I didn’t have it checked. There are no symptoms of onset, I would like to consult the doctor, I am almost 5 months pregnant, if I go to the hospital for examination and the result is to be operated, can the baby still be either? I want to have this child. Yin Jian, Department of Breast Oncology, Tianjin Cancer Hospital: It is necessary to go to the hospital for physical examination and ultrasound to make a preliminary diagnosis. If it is considered a benign lesion, surgery can be performed after stopping breastfeeding after delivery. If it is malignant, it should be in the 7th month of pregnancy now, and according to the specific stage of the tumor, it is necessary to decide whether to terminate the pregnancy or to operate after a few days when the fetus is estimated to be viable after cesarean section.
