Cancer is a family event Cancer is a family event, and over the past few decades, people have come to realize that cancer, as a life-threatening disease, is a negative life event, not only in terms of the psychological stress it causes to the individual, but also in terms of its impact on a family. Cancer affects the entire family emotionally, cognitively, and behaviorally, often altering the life, plans, and feelings of the entire family, resulting in economic and social losses, or even bringing down a family, causing it to break up and causing great psychological and life stress to family members. How the family, as a system, an organization, and an ethnic group, faces the blow of cancer is an important factor in whether cancer patients can obtain sufficient family support. And it directly affects the survival environment of cancer patients, psychology and the impact brought by the family, so the family itself is often deeply affected by this disease more, no matter in the stage of cancer treatment, or in the process of long-term adaptation to the disease, the family shoulders a double layer of responsibility for caring for and taking care of the patient, and the family members will be involved in the cancer patient’s emotions, sadness, depression, and acceptance of the fact that the experience and feelings, and at the same time, also to control their own emotions, manage their own internal emotions, take care of the patient and other pressures. Therefore the roles, needs and demands of all the people in the family will change at different stages of cancer, becoming a sense of uncertainty, ambiguity, and loss of control of the disease and other feelings, and for the disease progression or advanced stage, not only increase the fear of death of the cancer patient, the sense of threat of death irreversible death to the family and the patient has caused a great deal of pain, and a significant sense of physical and mental fatigue. In short, when a family member is diagnosed with cancer, the whole family changes with it. Under the influence of traditional family concepts, Chinese families are more deeply affected by the changes brought about by cancer. Concern for the cancer patient should be accompanied by greater attention to the psychological situation of family members. Only when the whole family copes well with cancer and faces it correctly can the patient receive good support and a favorable environment for treatment and recovery.
