Amongst the more common issues that patients and caregivers call PAF for help with include the inability to afford transportation expenses, inability to afford rent/mortgage, inability to afford their co-pay for medications, and inability to afford utilities and resulting shut-off notices. PAF serves patients with numerous health conditions, the majority of which have some form of cancer. Non-cancer diagnoses included rare diseases, chronic and debilitating conditions, nervous system conditions, cardiovascular conditions and vascular disease, autoimmune diseases, and diabetes. PAF solicits and receives donations to its programs from a multitude of sources including government agencies, non-profit organizations and for-profit organizations in the healthcare sector, including pharmaceutical manufacturers and healthcare providers.
