Cross sectional study to evaluate estimate accuracy of portable ultrasound device in correctly differentiating the benign breast lesions from the malignant ones in the women referred with a positive Clinical breast examination (CBE) screening test.
More than two million new cases of breast cancer occur each year worldwide. Implementing mammography screening is complex and resource-intensive, making it impractical in resource-limited settings. Clinical breast examination (CBE) has been recommended as an alternative screening option for low- and middle-income countries. Several studies have shown a significant shift towards earlier stage tumours detected by CBE. However, the high false-positive rate and low positive predictive value of CBE expose women to unnecessary and costly further diagnostic procedures, as well as the negative psychological consequences. There is an urgent need for a more accurate, cost-effective and reliable triage technology that can be performed by any healthcare provider.

| Triage of clinical breast examination positive women using handheld ultrasound by non-radiologists. | Other | Women screened for breast cancer by clinical breast examination (CBE). Those with positive CBE will be triaged by portable ultrasound device by non-radiologists. All recruited women will receive a diagnostic mammography and, if necessary, an ultrasound performed by a radiologist. The radiologist will be blinded to the portable ultrasound device findings. Those with suspected lesions either on mammography or ultrasound will have fine needle aspiration cytology (FNAC) or core biopsy. The women with confirmed diagnosis of breast cancer will be staged and appropriately treated as per the policy of the hospital. |

| Accuracy of non-radiologist portable ultrasound device for triaging women with positive clinical breast examination | Sensitivity, specificity and positive and negative predictive values of portable ultrasound device to detect breast cancer and carcinoma in situ with repeat clinical breast examination, mammography/ultrasound and/or cytology/core biopsy as the gold standard test. | Through study completion, an average of 1 year |

This is a single-arm study in which women with a positive clinical breast examination will be triaged using a portable ultrasound device by non-radiologists. The gold standard is mammography, ultrasound and histology if needed.
