Final answer:
A cancer registry is an information system designed for the collection, management, and analysis of data on individuals with malignant diseases, aiding in medical research, patient care, and informing public health strategies.
Step-by-step explanation:
An information system designed for the collection, management, and analysis of data on a person with a malignant disease is known as a cancer registry. A cancer registry collects health records, stages of cancer, and other important data related to cancer patients. This data supports medical research, helps in understanding cancer trends, and improves cancer treatments. The role of cancer registries becomes crucial when determining the prognosis and appropriate treatment for patients, as well as in protecting patient privacy and balancing the cost of treatments.
In addition to informing policies and treatments, cancer registries are used to monitor and improve cancer care, facilitate epidemiological research, and manage public health strategies. The data collected aids in understanding the effectiveness of various treatment options, which can lead to better outcomes and improvements in patient quality of life.
People think carefully about whether to receive a diagnostic test such as a CT scan because the radiation from a CT scan is capable of creating cancerous cells. Therefore, the benefits of such diagnostic tools must be weighed against the potential risks, and this careful consideration is reflected in the policies of medical ethics and patient care.
