Triple negative breast cancer

Discussion:

Triple negative breast cancer (TNBC) is type of malignant breast lesions, commonly occurring in young women. Its name comes from the fact that the cells lack the receptors of estrogen, progesterone and HER2 protein 1.

Small lesions (< 2 cm) can be tricky on ultrasound and mammography mimicking benign lesions like fibroadenoma. TNBC tumors tend to show more suspicious ultrasound features and greater tumor roundness than fibroadenomas 1

MRI will show the rim enhancement which is an MRI feature of malignant breast lesions 2.
