The occurrence of breast cancer creates psychosocial stress for both the patient and her family. Because of the threat to the patient's life and frequent disfigurement that results from breast cancer, interpersonal relationships, particularly the marital/sexual relationship and the mother/daughter relationship, are adversely affected. The related literature suggests that while many families may experience growth and greater closeness due to the disease, a significant number experience relational difficulties. Much of the literature stresses how crucial communication, acceptance, and support from family members are to the recovery and well-being of the patient. A study of 36 breast cancer patients between the ages of 35 and 82 who sought help from a social service agency supports the notion that many victims of the disease are not receiving the kind of support they need from family members. A number of women reported being unable to talk to their mates about the cancer and experiencing conflict with adult daughters, often ending in a severing of relations. Of those who were widowed or divorced, many relied on neighbors or church members for support. Evidence from the related literature and the study suggests that the needs of the family must be considered along with those of the patient. (Fifty-one references are included.) (JC)
