Theories of Loss and Grief Experienced by the Patient, Family, and Healthcare Professional: a Personal Account of a Critical Event.

When a patient is diagnosed with cancer, a number of losses and grief processes occur. Theories and models of loss, grief, and mourning are explored for the patient, her family member, and the medical treatment team, through a personal reflection when treating a patient undergoing a course of radiation treatment in a large cancer center. Reflection on this event can be used to guide health care facilities to assess and develop support systems for patients, caregivers, and health care professionals to cope with loss and grief processes in a healthy and meaningful way.
