According to projections from the American Cancer Society. Based on comparisons between 2022 cancer data from the Centers for Disease Control and Prevention and 2026 estimates, several states are projected to experience notable increases in new diagnoses.

Delaware is expected to record the highest percentage growth in cancer cases, followed by Massachusetts, Indiana, and Idaho. Meanwhile, more populous states such as Florida and Texas are projected to experience the largest increases in total case numbers due to their population size.

Overall, twelve states are forecast to see cancer diagnoses rise by at least 20% this year, highlighting a growing healthcare challenge and the need for expanded prevention, early detection, and treatment strategies across the country.
