Hello and welcome to HCM,
Triple negative breast cancers are associated with poor prognosis.
You have mentioned that your daughter has developed sores and bumps on the skin.
These lesions can be recurrence of breast cancer.
A prompt aspiration and/or
biopsy of these bumps is required.
Aspiration cytology will identify if malignant cells are present or not..
If malignant cells are present, a biopsy can be done and
immunohistochemistry can be performed to know the immune profile of the lesion.
On the basis of these investigations, further management can be performed.
Chemotherapy and radiotherapy can be planned according to the results of the investigations.
Triple negative tumors have poor prognosis and there are chances of distant metastasis is also present.
Thanks and take care
Dr Shailja P Wahal
