Intermediate Markers and Molecular Genetics of Lung Carcinogenesis.

: BACKGROUND: Various options are available for the local control of cancer in the breast - mastectomy, conservation therapy, and mastectomy with reconstruction. METHODS: To evaluate the benefits and drawbacks of the available management options, the authors combine their extensive experience with a review of the literature on outcomes from these approaches. RESULTS: Conservation therapy provides survival outcomes similar to those from mastectomy. Differences in local recurrence rates can be minimized by close adherence to guidelines for patient selection, operative approach, and radiation technique. CONCLUSIONS: The role of the physician in selecting a local therapy for breast cancer has changed from one of informing the patient of the treatment to assessing the presence of medical contraindications to any of the treatments, educating the patients on each treatment approach, providing access to multidisciplinary consultation, and allowing the patient to choose an appropriate treatment approach.
