This observational study aims to understand how the immune system responds to breast cancer in young women. Researchers will look at how much the immune system is suppressed in different types of breast cancer, including those related to pregnancy (Pregnancy Associated Breast Cancer or PABC). They will use blood, urine, and tissue samples to compare PABC with non-PABC cases, and also compare different types of breast cancer. This research will help scientists better understand how breast cancer works and could lead to new treatments in the future. You may be able to join if you are a woman over 18 with a confirmed breast cancer diagnosis and have tissue samples available. The main goal is to see how long people live without their cancer getting worse (Progression Free Survival) throughout the study.
