As long as the condition of breast cancer patients allows, they can get married and have children. Marriage and childbirth, happy and harmonious family life will not only not aggravate the progress of the disease, but also enhance the immunity of the body, which is beneficial to the recovery of the disease. However, due to the rapid progress of the disease in young unmarried female patients under 35 years old with axillary lymph node metastasis, it is generally not advisable to have children after marriage for the time being. It is recommended that 3 to 5 years after surgery, no obvious tumor recurrence or metastasis is found and the disease is stable before considering marriage and childbirth, and a comprehensive physical examination should be carefully conducted before marriage to make adequate physiological and psychological preparations, and at the same time, there should be pregnancy health guidance from specialist doctors.
