A study reveals that the rate of new cases in those over 55, who still make up the majority, remains stable, but diagnoses are increasing at younger ages
I hate to spoil it for those who actually read the article, but since you asked:
In wealthy countries, where there has been “success in detection, diagnosis, and treatment,” the authors say, the incidence remains stable and mortality rates are declining (five-year survival rates are between 85% and 90%). In contrast, lower-income regions are experiencing an explosion of new diagnoses, and due to deficiencies in their healthcare systems and limited (or nonexistent) access to top-tier diagnostic and therapeutic resources, mortality rates are also skyrocketing (one study in Africa placed the three-year survival rate at 50%).
Increase in detection due to more awareness and testing?
