How to choose a cancer center
Make sure any cancer center you choose has been accredited by the joint commission on accreditation of healthcare organizations (jcaho).
From the jcaho website, you can check if a specific facility has met accreditation standards. The website also allows you to peruse performance evaluations.
Determine if the facility is approved by the national cancer institute (nci). You can search the nci's database on its website.
