Healthcare Access

Advanced cancer diagnostics and treatments exist that consistently improve outcomes. Hereditary genetic testing, tumor profiling, precision oncology, targeted therapies, and clinical trial participation are all supported by strong clinical evidence. The challenge is often not whether these tools work, but whether patients can realistically access them when they need them most.

Barriers, including cost, insurance limitations, geography, physician awareness, provider shortages, and systemic inequities, continue to prevent many individuals from receiving the level of care modern medicine can now provide. In many cases, access depends heavily on where a person lives, what type of insurance they have, or whether they are treated within major academic medical systems. Millions of patients who may benefit from genetic testing, molecular profiling, specialized oncology support, or clinical trials never receive those opportunities.

Healthcare access also extends beyond diagnostics and treatment itself. Delays in referrals, lack of awareness about testing eligibility, unequal access to specialists, and limited support navigating the healthcare system can all influence outcomes in meaningful ways. For some patients, these delays reduce the ability to intervene earlier, personalize treatment decisions, or explore additional options before the disease progresses.

The articles in this section examine the gaps that exist across cancer prevention, diagnosis, treatment, and survivorship care. They explore the systemic barriers that create disparities in access, along with the programs, technologies, and patient-centered approaches working to close those gaps.

Explore the articles below to better understand how healthcare access shapes cancer outcomes, why these disparities persist, and what is being done to improve access to precision medicine and modern cancer care for more people.
