While your healthcare team should be your first source of information, it's good to know there are other places you can turn for support. National cancer organizations offer information, resources, and other services for people with cancer and their caregivers.
Support groups may be especially helpful. Many patients coping with cancer find comfort and strength through support groups, which connect them with other patients dealing with cancer's day to day challenges.
