What is a core practice in secondary disease prevention?

The core practice in secondary disease prevention focuses on identifying and addressing health issues at an early stage to prevent their progression. Confirming diagnosis in early stages is essential as it allows for timely intervention and management of diseases before they become more severe or difficult to treat. This practice aims to reduce the impact of the disease on the individual's health and overall quality of life.

Promoting healthy lifestyle choices is fundamental for primary prevention, which seeks to prevent diseases before they occur. While it is important, it does not fit within the framework of secondary prevention, which is more concerned with detection and early treatment.

Completely eliminating the disease does not fall under secondary prevention, as it is often not feasible to eradicate certain diseases, especially those that are chronic or genetic in nature. This focus aligns more closely with primary prevention strategies or public health initiatives.

Providing rehabilitation for chronic diseases is more relevant to tertiary prevention, which focuses on managing long-term health effects and improving the quality of life for those with established diseases. This aspect does not address the need for early detection and intervention that is central to secondary disease prevention practices.

Thus, confirming diagnosis in early stages stands out as the correct answer, as it directly reflects the objectives of secondary prevention strategies in health education and practice.
