Why would they do a lumpectomy without biopsy first?

Lumpectomies are typically performed after a biopsy has been done and a diagnosis of breast cancer has been made. In circumstances where a biopsy is inconclusive, a doctor may make a clinical judgement and choose to first perform a lumpectomy to obtain more tissue samples for further analysis. Other potential reasons for performing a lumpectomy without prior biopsy include:

* When a biopsy is not feasible: In cases where a biopsy cannot be safely or effectively performed due to factors such as the location or size of the breast lesion or the patient's health condition, a lumpectomy may be done first.

* When the biopsy results are inconclusive: If a biopsy does not provide a clear diagnosis, a lumpectomy may be necessary to obtain more tissue for a more accurate assessment.

* When there is a high risk of breast cancer: In situations where there is a strong clinical suspicion of breast cancer based on imaging findings or other factors, a lumpectomy may be performed to make a definitive diagnosis and allow for prompt treatment if necessary.

It's important to note that the decision to perform a lumpectomy without a prior biopsy is made by a qualified medical professional based on a thorough evaluation of the patient's individual situation.
