Breast cancer is a prevalent malignant neoplasm, and the selection of treatment strategies often necessitates consideration of multiple factors, including the tumor's pathological classification, molecular marker expression, and the patient's physical health. Notably, PD-L1 (Programmed Death-Ligand 1), an immune checkpoint protein, may be expressed on certain breast cancer cells and is potentially linked to the tumor's mechanisms of immune evasion. Consequently, assessing PD-L1 expression levels in breast cancer cells is crucial for informing clinical treatment decisions.

Typically, elevated PD-L1 expression in breast cancer cells could indicate a stronger capacity for immune evasion, potentially conferring resistance to conventional chemotherapy or radiotherapy. In such instances, clinicians might consider immunotherapies, such as PD-1/PD-L1 inhibitors, to enhance the patient's immune system's ability to recognize and target cancer cells. However, it is important to recognize that not all PD-L1-positive breast cancer patients will benefit from immunotherapy, as the tumor's immune microenvironment, genetic mutation status, and expression of other molecular markers can also influence treatment outcomes.

For patients with breast cancer, particularly those with PD-L1-positive tumors, maintaining healthy lifestyle habits is essential. This includes a balanced diet, regular physical activity, abstaining from smoking, and limiting alcohol consumption to boost immune function and better manage the challenges encountered during treatment. Additionally, patients should vigilantly monitor their condition, undergo regular follow-ups and testing to facilitate timely adjustments to their treatment plan. Prior to using any medication, it is imperative to adhere to the physician's recommendations and avoid self-medicating to prevent unnecessary health risks.
