In many human cancers, the cell cycle is dysregulated, leading to uncontrolled proliferation [1.3.2, 1.4.1]. G1 inhibitors, a class of targeted therapy, address this by blocking specific enzymes. Understanding the query, 'How do G1 inhibitors work?' reveals their crucial role in modern oncology, particularly for HR-positive, HER2-negative breast cancer [1.5.4].

In a recent FAERS database analysis, neutropenia was the most frequent adverse event signal for letrozole, though the risk is significantly higher when combined with CDK4/6 inhibitors. This distinction is crucial for understanding whether does letrozole cause low neutrophils in a patient's specific treatment plan.
