Cancer Screening
Cancer Screening
Methods employed to detect cancer or abnormal cells that may turn cancerous when people do not have symptoms are considered as screening methods.
The Power of Early Detection
It is easier to treat an early cancer (WITHOUT SYMPTOMS) when it has not spread than when it has become symptomatic (MAY HAVE SPREAD).
Benefits of Cancer Screening
Early Detection
Detect cancer or abnormal cells before symptoms appear
Better Treatment Outcomes
Easier to treat early cancer that hasn’t spread
Reduced Mortality
Help reduce the probability of death due to cancer
Understanding the Limitations
While screening is valuable, it’s important to understand potential drawbacks and limitations
False Positive Results
Test indicates cancer is present when it may not be present
Causes anxiety and leads to additional tests with potential harms
False Negative Results
Test indicates cancer is not present when it actually is
Gives false assurance and delays diagnosis when treatment could be curative
Over Diagnosis
Screening detects slow-growing, harmless cancers
Treatment may not alter lifespan but results in unnecessary procedures
