[The adequate operation, an essential element of interdisciplinary cancer therapy]

Operative treatment plays a dominant role in our effort for cancer control. The results, e.g. in breast cancer, cancer of the stomach and colon, malignant melanoma, malignant teratoma of the testicle, mixed tumours of the salivary glands, and sarcomas of soft tissues demonstrate that local tumour relapses and/or local metastases may be avoided by adequate, sufficiently radical operative techniques.
