Overview
Breast ultrasound may be helpful in the diagnosis of breast cancer.
Findings on ultrasound
- Breast ultrasound is not as sensitive as mammography in diagnosing breast cancer.
- It may be used to:[1]
- Examine a breast lump or abnormality found during a clinical breast examination or mammogram
- Determine if a breast lump is a solid tumor or a fluid-filled cyst (sac in the body that is usually filled with fluid or semi-solid material)
- Find an abnormal area for a biopsy
- The addition of ultrasound decreases the false negative rate of diagnostic mammography, but we should keep in mind that a negative ultrasound and/or mammography does do not exclude the presence of breast cancer.
- Color Doppler ultrasound:
- May aid in the assessment of breast masses
- The absence of flow on Doppler study does not exclude the possibility of malignancy.
Liver Ultrasound
If the blood chemistry tests show increased levels of liver enzymes, a liver ultrasound may be done to check if cancer has spread to the liver (liver metastases). [1]
Herceptin (trastuzumab) induced heart failure
- Trastuzumab is a HER2 receptor blocker, which is used to treat HER2 positive breast cancer.
- It has been shown that heart failure is prevalent in women being treated with this novel treatment.
- According to a small study 58% of women treated with Herceptin for three months, showed pieces of evidence of loss of heart function. (Ref)
- As a potentially serious side effect of this novel treatment serial Echocardiography is recommended in all patients treated with trastuzumab.
