The FPL plays a significant role in the lives of cancer patients, influencing their access to medical care, treatment options, and support services. Patients below a certain percentage of the FPL may qualify for Medicaid, the Children's Health Insurance Program (CHIP), and subsidies for insurance plans through the Affordable Care Act (ACA) marketplaces. These programs are critical for ensuring low-income cancer patients receive necessary treatments without the added burden of financial stress.
