Why would a script for mammogram say malignant neoplasia other?

"Malignant neoplasia other" is a general term used in medical reporting to indicate the presence of cancerous cells in a tissue sample, without specifying the specific type of cancer. It is often used when the exact type of cancer cannot be determined with certainty, or when further testing is needed to confirm the diagnosis.

In the context of a mammogram, "malignant neoplasia other" would indicate that the radiologist has identified suspicious findings suggestive of cancer on the mammogram images, but further evaluation is necessary to determine the specific type of cancer. This could involve additional imaging studies, such as ultrasound or magnetic resonance imaging (MRI), and/or a biopsy to collect a tissue sample for examination under a microscope.

The term "other" is used to differentiate this general type of malignant neoplasia from more specific types of cancer, such as invasive ductal carcinoma or invasive lobular carcinoma, which are the most common types of breast cancer.

By using the term "malignant neoplasia other," the radiologist is conveying that there is evidence of cancerous cells, but the exact type of cancer and its extent cannot be determined based solely on the mammogram findings. Further evaluation is necessary to make a definitive diagnosis and determine the appropriate treatment plan.
