A 2025 National Cancer Institute study identified 14 types of cancer with rising rates among Americans under 50, while alarming new maps reveal where the disease is striking hardest. Roughly three out of four Americans diagnosed with colorectal cancer before age 50 already have advanced-stage disease, according to the American Cancer Society's 2026 statistics. Colorectal cancer rates among adults ages 20 to 49 have been climbing approximately 3% annually, while rates among Americans 65 and older have been falling.

The findings have left some of the nation's leading cancer researchers confronting an increasingly urgent question: What is driving this troubling rise in cancer among younger Americans?

Breast cancer rates are especially high among younger women in parts of the Northeast and East Coast, while colorectal cancer increases stretch from California and the Pacific Northwest to Florida.

Pancreatic cancer presents an even more troubling picture, with rates among Americans under 50 climbing nearly 3% annually and increases recorded across much of the South, Midwest and East Coast.
