Summary
Breast cancer is the most common cancer in the UK, accounting for 15% of all new cancer cases. There are around 56 800 new breast cancer cases in the UK every year; of these, 9% occur in women at or under 44 years of age. Survival rates have improved significantly in recent decades. In women diagnosed under the age of 39 years, 85% are alive more than 5 years after their diagnosis leading many women to now consider pregnancy as an option after cancer. A new breast cancer diagnosis complicates about 1 in 3000 pregnancies. With advancing maternal age at pregnancy it is likely that the incidence of breast cancer during pregnancy will increase.
The purpose of this guideline is to describe the diagnosis, management and treatment of breast cancer during and immediately after pregnancy. It also provides multidisciplinary clinical guidance on how to care for women of reproductive age with a diagnosis or history of breast cancer and future fertility considerations following a breast cancer diagnosis
