Secondary prevention

Secondary prevention aims to detect and treat disease early, before it has a chance to cause serious harm. This can be done through a variety of means, including:

* Screening tests: Screening tests can help to detect diseases early, when they are often more easily treated. Examples of screening tests include mammograms for breast cancer, Pap tests for cervical cancer, and colonoscopies for colon cancer.

* Early diagnosis: If you have symptoms of a disease, it is important to see a doctor right away so that it can be diagnosed and treated as early as possible.

* Palliative care: Palliative care focuses on providing comfort and support to people who are living with a serious illness.

* End-of-life care: End-of-life care focuses on providing comfort and support to people who are dying.
