NCCN guidelines are comprehensive decision tools that provide details on cancer intervention, management and care. Oncologists and other professionals involved in cancer care use these guidelines to determine the best course of action for a cancer patient depending on her age, diagnosis and disease stage.
The NCCN guidelines are the recognized standard in cancer care, and they cover 97 percent of cancers that affect the United States. These guidelines are updated and revised regularly to reflect the new data and research that may alter or add to the current clinical practice standards. Experts develop these standards based on reviews of evidence such as clinical trials and recommendations from 48 individual panels.
There are currently 60 NCCN guidelines that cover cancer prevention, detection, risk reduction, diagnosis, treatment and supportive care issues, as of 2015.
