Breast cancer can be pregnant after chemotherapy, but regular checkups are needed to prevent tumor recurrence, and recurrence requires strict compliance with the doctor’s instructions to receive treatment. During the period of chemotherapy, it is not recommended to get pregnant due to the side effects of chemotherapy drugs, which may cause teratogenic effects on the fetus. Meanwhile, pregnancy is also not recommended during the period after chemotherapy as the chemotherapy drugs still remain in the body for a certain period of time. Breast cancer patients can get pregnant after stopping chemotherapy for more than half a year, but due to the fluctuation of hormone level in the body during pregnancy, it is easy for the tumor to recur, so it is recommended to have regular checkups and follow the doctor’s instructions strictly to prepare for pregnancy, and actively cooperate with the doctor to accept the follow-up treatment in the event of recurrence.
