It has been reported that some patients have been misdiagnosed with Phyllodes Tumor, when in fact the correct diagnosis in their specific case was Breast Cancer.
Breast cancer while incredibly common is very curable if caught early on. However around 13% of breast cancer cases are diagnoses are missed by medical professionals. Cancerous breast masses can be mistaken for blocked milk ducts, or cysts. The main issue with misdiagnosis of breast cancer is that if not treated early on cancer of the breast tissue can easily travel to the lymph nodes and from there infiltrate other tissues and organs. Metastasised cancer is incredibly difficult to treat and almost guarantees death for the patient.
