Healthcare advocacy involves supporting and promoting the rights and needs of patients within the healthcare system. Advocates work to ensure that individuals receive appropriate care, understand their treatment options, and have access to necessary resources. This can include helping patients navigate insurance issues, providing information about medical conditions, and representing their interests in discussions with healthcare providers. Advocates can be professionals, such as social workers or nurses, or volunteers who are passionate about improving healthcare access. Organizations like the American Cancer Society and Patient Advocate Foundation play crucial roles in educating patients and influencing healthcare policies to create a more equitable system.
