Thank you for asking your health related query at HCM. The MRI
suggests that there is a suspicious area in your left breast (BIRADS 4 - is indicative that it is suspicious for malignancy). The next logical step would be to carry out a biopsy
of this lesion to rule out cancer.
As the lesion is small, the biopsy would be done under ultrasound
You should consult a dedicated breast surgeon, who can carry out the biopsy and then proceed with the treatment.
