Cancer surgery delays in the US have steadily worsened over a decade

Cancer treatments have become more effective and survival rates have climbed over the past decade, yet one critical measure of care quality has deteriorated: how long patients must wait to get surgery. A major study reveals that delays for cancer operations have grown consistently across the US, despite advances in medical science.

The widening gap#

Researchers at UCLA analyzed data from more than 2.7 million patients diagnosed between 2012 and 2023 with early-stage cancers requiring surgery. They examined findings published in JAMA Surgery across six common cancer types—breast, colon, lung, pancreatic, gastric, and esophageal.

The trend is unmistakable. Average wait times for all six cancer types have stretched out over the past eleven years:

• Breast cancer: 34 days (2012–2015) → 45 days (2022–2023)
• Colon cancer: 20 days → 31 days
• Lung cancer: 41 days → 53 days
• Pancreatic cancer: 23 days → 32 days
• Gastric cancer: 35 days → 49 days
• Esophageal cancer: 38 days → 48 days

Why delays matter#

Prompt surgery is a hallmark of quality cancer care. Research has connected postponed operations to worse patient outcomes, including lower survival rates and elevated psychological burden. Each increment of delay can shift the odds for vulnerable patients who may face rapidly advancing disease.

The study also documented a troubling uptick in extreme delays, with more patients experiencing 60-day waits or longer, and growing shares enduring the 30-day threshold that often signals systemic strain.

What's driving the slowdown#

While the data lay bare the problem, the underlying causes—whether staffing shortages, operating room capacity constraints, or post-pandemic recovery pressures—remain an open question warranting deeper investigation into healthcare system resilience and resource allocation.
