Active and Passive Cancer There are two types of surveillance for diseases of interest, which are active and passive. Cancer is the disease you need to research for this project. Answer the following questions:
1. Does the disease I selected have active or passive surveillance systems in place and why? (300 minimum words for passive surveillance) and (300 minimum words for active surveillance) APA
Cancer Surveillance: Active vs Passive
Cancer is a complex and multifaceted disease that can affect different parts of the body. Cancer surveillance is crucial for monitoring the incidence, prevalence, and mortality rates of cancer, identifying risk factors, and guiding prevention and treatment strategies.
Passive surveillance is a system in which disease cases are reported by healthcare providers, laboratories, or other sources to public health agencies on a voluntary basis. Passive surveillance for cancer is commonly used in many countries, including the United States, Canada, and Australia. Cancer is a reportable disease, which means that healthcare providers are required by law to report all……..
Active surveillance is a system in which dedicated personnel actively seek out and identify cases of the disease of interest. Active surveillance for cancer is less commonly used than passive surveillance, but it can provide more complete and accurate data, especially for rare cancers or populations with……………
2. What are the limitations of these surveillance systems? (give at least 2 types of surveillance systems 300 words minimum each)
There are two types of cancer surveillance systems: passive and active. Both systems have limitations that can affect the accuracy and completeness of cancer data.
Limitations of passive surveillance:
- Underreporting: Not all cancer cases are reported to cancer registries due to various reasons, such as incomplete reporting from healthcare providers or lack of awareness among patients.
- Data quality: Passive surveillance relies on the accuracy and completeness of data provided by
Limitations of active surveillance:
- Selection bias: Active surveillance methods, such as cancer screening programs, may not reach all eligible individuals, resulting in a biased sample that may not be representative of the population.
- Resource-intensive: Active surveillance requires dedicated personnel, specialized equipment, and
3. What is the case definition for this disease? How might changing the case definition impact surveillance?
The case definition for cancer varies depending on the type and location of the cancer. Generally, cancer is defined as the abnormal growth and spread of cells in the body. The diagnosis of cancer is based on various criteria, such as histology, morphology, stage, and behavior.
Changing the case definition for cancer can impact cancer surveillance in several ways. For example, changing the criteria for cancer diagnosis may result in changes in the number and types of
