[Partnership and family aspects of cancer].

Cancer is not only a challenge for the patient, but can also be associated with psychosocial distress for relatives, especially partners and minor children. Although studies on the long-term effects of cancer on partners, the partnership, and child development are still rare, there are indications that the psychological distress on relatives may become chronic, and that parental illness is a risk factor for a child to develop mental disorders. In addition, a deterioration in partnership satisfaction also increases the risk of separation.Psycho-oncology care should therefore not only consider the patient's psychosocial burden but also that of the partner, as well as its effect on the partnership. Appropriate offers, for example to increase partnership and sexual satisfaction, communication, or dyadic coping, should be made. Children should also be treated as relatives in care. Focusing on both the child's distress and on improving the parent-child relationships and parenting behavior can help children to cope with parental illness in the long term. Thus, cancer should be viewed on the individual, dyadic, and family level, and psychosocial care services should be provided at all levels.
