Changes in Cancer Staging: What You Should Know
When you learn you have cancer, you want to know what to expect: How will doctors treat your illness? How effective is treatment likely to be?
Much depends on the way doctors first classify, or “stage,” your cancer, using the official staging manual from the American Joint Committee on Cancer.
Staging guidelines continue to evolve as knowledge about individual tumor growth and innovative technologies come into play.
An ever-evolving system
“Historically, we staged cancers according to tumor size, lymph node involvement and the presence of metastases,” says oncologist Dale Shepard, MD, PhD.
“The latest staging manual incorporates new findings on the importance of changes in molecular DNA and tumor genomic profiling. This will affect many patients going forward.”
Among those most impacted by changes in staging are people newly diagnosed with breast cancer; head and neck cancer caused by human papillomavirus (HPV); or sarcoma.
