Early cancer detection is a topic that provokes much energy, excitement and discussion. Early detection may save lives as well as reduce costs to individuals, society and the economy for caregiving.

In order for screening tests to be effective, certain criteria must be fulfilled. At the core is having access to a proven and safe test.

Reduced Mortality Rates

Early stage cancer diagnoses tend to have better prognoses. This is especially true if detected before they have spread throughout the body.

Early cancer detection increases treatment effectiveness, so attending screenings regularly is of vital importance.

Screening can help reduce mortality rates, although its evidence remains uncertain. Many studies support the argument that screening saves lives; especially compelling are studies comparing those with early diagnoses to those without.

Unfortunately, such studies can be complex to conduct and suffer from numerous limitations that make their results inconclusive for convincing skeptics of the benefits of screening; uncontrolled epidemiological data and case series studies often do not convince individuals otherwise; additionally they don’t specify health outcomes prevented or money saved by forgoing treatments for advanced-stage cancers.

Increased Survival Rates

Early stage cancers that have not spread too widely tend to be easier to treat, often with minimally invasive surgical procedures or shorter drug regimens, and with fewer side effects and harmfulness to other parts of the body.

Cancer cases diagnosed early have an improved chance of survival. This applies across all cancer types; but is particularly apparent for those detected through screening programs or through symptoms presented to primary care.

Survival rates have improved substantially in recent years, yet the exact cause isn’t always apparent. While better treatments might contribute to an increase in survival rates, so could developing earlier detection methods increase them even more? Sensitivity and specificity must also play a part – for instance a blood test that detects cancer cells or circulating DNA must differentiate them from healthy samples while simultaneously being highly specific.

Fewer Side Effects

Early diagnosis and treatment for low-risk cancers such as prostate, breast, or colon adenocarcinomas that can be effectively addressed via surgery or chemotherapy is key in limiting potential side effects from treatment. This holds especially true in cases with cancer that has no chance of spreading, such as prostate carcinoma.

Research continues to advance methods of early cancer detection. New technologies are being created that can detect changes to DNA or other substances within the body before symptoms appear, providing potential solutions for cancers that do not yet have reliable screening tests available.

Other initiatives aimed at increasing early diagnosis include identifying barriers to symptomatic presentation (eg, anxiety over wasting a doctor’s time, fatalism and fear) as well as encouraging health-care professionals to investigate suspected cancer patients more aggressively. Behavioural science can assist in identifying key barriers and designing targeted interventions or campaigns to address them; this has proven successful at increasing screening participation rates and decreasing rates of symptomatic cancer detection.

More Effective Treatment

Early cancer detection offers many treatment options that are both cost-effective and have less adverse side effects, leading to improved results and fewer side effects. Surgery or lower dosage chemotherapy drugs may provide effective solutions, leading to quicker healing times with fewer side effects for improved results.

Current effective screening tests exist for only a select few cancer types; mammography, prostate specific antigen testing and colonoscopy are currently the three most widely utilized screening tools.

However, new blood-based biomarkers can detect cancer earlier than traditional screening methods can. One such biomarker is circulating tumor DNA (ctDNA) found in blood plasma; studies such as PanSeer have demonstrated it can detect cancer four years prior to conventional diagnosis.

Rapid diagnosis and treatment are key elements in increasing your odds of a positive cancer diagnosis outcome. Scheduling regular check-up appointments as well as developing healthy lifestyle habits such as not smoking and following a balanced diet are also vital in this respect.
