It can be confusing when two people with “breast cancer” receive different treatments. The reason is that breast cancer is not a single uniform disease, and treatment decisions are based on much more than the name of the organ involved.
Pathology helps define the tumour
After a biopsy or surgery, the pathology report can describe the cancer type and other features. Hormone receptors such as ER and PR, HER2 status and additional tumour characteristics can influence treatment choices.
Stage changes the treatment goal and sequence
Early breast cancer may involve a combination of surgery, radiation and systemic treatment. In selected situations, medical treatment is given before surgery. Advanced or metastatic breast cancer usually requires a different strategy focused on controlling disease over time and maintaining quality of life.
Systemic treatment can take several forms
Depending on the tumour, treatment may include hormone therapy, chemotherapy, targeted therapy, immunotherapy or combinations. Not every patient needs every type of treatment.
Personal factors also matter
Age alone does not decide treatment. General health, other medical conditions, previous treatments, fertility considerations, patient preferences and treatment goals can all be relevant.
