Late Stage Breast Cancer (Stage III and IV)
First-trimester radiation therapy should be avoided. Chemotherapy may be given after the first trimester as discussed in the section on Early Stage Breast Cancer. Because the mother may have a limited life span (most studies show a 5-year survival rate of 10% in pregnant patients with stage III and IV disease), and there is a risk of fetal damage with treatment during the first trimester,[1,2] issues regarding continuation of the pregnancy should be discussed with the patient and her family. Therapeutic abortion does not improve prognosis.[1-5]
