A patient has a mammogram with a probable malignant impression. What is the date of initial diagnosis for breast cancer?

The initial diagnosis date for breast cancer is typically marked by the first significant clinical evidence indicating a diagnosis. In this context, if a patient has a mammogram showing a probable malignant impression, the date of that mammogram would be the date of initial diagnosis, assuming that it is within a reasonable time frame and clinical follow-up doesn’t delay the diagnosis further.

If we consider the date 4/1/2024 as the date of the mammogram, this aligns as the point where the assessment begins to indicate malignancy, leading to subsequent steps for confirmation, such as a biopsy. The dates following that in April or August would indicate later stages in the diagnostic process, such as the receipt of biopsy results or the beginning of treatment, which do not define the initial finding of breast cancer.

Therefore, 4/1/2024 is the proper date for initial diagnosis when the mammogram suggests malignancy, leading to further evaluation.
