Can i find out if a breast cyst / tumor is malignant through a breast ultrasound and mammogram?

Suspicious only: Imaging techniques other than an MRI may be an indication of the level of suspicion for malignancy in the context of several other findings on history and physical examination. However, a diagnosis ultimately requires a biopsy.

Sometimes.: There are lesions that can be determined with a high level of assurance to be benign and lesions that can be determined to be malignant.. There are also many lesions that cannot be determined with a high degree of certainty with these sstudies alone.

No, : a biopsy is necessary to definitively diagnose malignancy. Mammo/US evaluation will give you the probability of malignancy based on the BIRADS code: BIRADS 2 is benign, 3 is probably benign(less than 1% chance of cancer), 4 is suspicious(about 30% chance), 5 is highly suspicious(at least 75%).
