A breast cancer grade 5 indicates a high suspicion of malignancy, but it cannot confirm whether the disease is in an advanced stage. Even if various examinations suggest a grade 5 breast cancer, although the likelihood of malignancy is high, this alone cannot serve as a definitive diagnosis or basis for staging. The patient must undergo a pathological biopsy via needle puncture to confirm whether it is indeed breast cancer. Additionally, clinical staging can be determined based on factors such as tumor size and whether there is evidence of spread.
