Gestational breast cancer (GBC) or pregnancyassociated
breast cancer was defined as breast cancer
diagnosed during pregnancy and within 1 year of
delivery. Breast cancer is the second commonest cancer
after cervical seen in pregnancy and lactation.
Nevertheless, the incidence is low and accounts for
approximately 1 in 3000 of pregnancies. A delay in
diagnosis is common and 70% to 89% of patients with
operable primary lesions already have positive axillary
lymph nodes. Breast cancer identified during pregnancy
can be extremely distressing for the mother despite it
has similar course of disease and prognosis seen in nonpregnant
women of the same age and stage of disease.
Diagnostic and treatment options should be carefully
decided to prevent further harm to the mother or any
potential risk to the developing fetus.
