We already know that early detection of cancer
- Reduces the time required for treatment
- Reduces the cost required for treatment
- Improves the outcome in terms of five-year survival rate
Cancer screening is invaluable.
Now a new study from the Cleveland Clinic shows that the time lapse between detection of cancer and the start of treatment also matters. Each week that passes between diagnosis and the start of treatment impacts the five-year survival rate.
Longer delays between diagnosis and initial treatment were associated with worsened overall survival for stages I and II breast, lung, renal and pancreas cancers, and stage II colorectal cancers, with increased risk of mortality of 1.2 percent to 3.2 percent per week of delay, adjusting for comorbidities and other variables.

In the example of stage I non-small cell lung cancer, the five-year survival rate is
- 56% if treatment starts within 6 weeks versus
- 43% if treatment starts later
The problem is that the length of time between diagnosis and treatment has been increasing since 2004.
What you need to consider:
- With cancer, once diagnosed, time is of the essence.
- Checkups and screening are essential.
- Cancer can strike at any age.
