RATIONALE: Cryosurgery kills cancer cells by freezing them. Cryosurgery followed by lumpectomy or mastectomy may be an effective treatment for breast lesions. PURPOSE: Phase I trial to study the effectiveness of cryosurgery in treating women who have breast lesions.

Study summary:

OBJECTIVES: - Determine the feasibility of temperature-monitored, ultrasound-guided cryosurgery in women with highly suspicious breast lesions. - Determine the safety of this procedure in these patients. OUTLINE: This is a multicenter study. Patients undergo cryoablation of up to two breast lesions. Within 3-21 days, patients undergo lumpectomy or mastectomy. Patients are followed at 1, 4, 8, and 12 weeks after lumpectomy or mastectomy. PROJECTED ACCRUAL: A maximum of 25 patients will be accrued for this study.


DISEASE CHARACTERISTICS: - Highly suspicious breast lesion on prior mammogram and/or ultrasound with confirmation of malignancy on ultrasound-guided core biopsy - Tumor no greater than 2.0 cm in diameter - Eligible for lumpectomy or mastectomy - No superficial breast lesions - No prior open surgical biopsy - Hormone receptor status: - Not specified PATIENT CHARACTERISTICS: Age: - Any age Sex: - Female Menopausal status: - Not specified Performance status: - Not specified Life expectancy: - Not specified Hematopoietic: - Not specified Hepatic: - Not specified Renal: - Not specified Other: - No other illness that would preclude study participation PRIOR CONCURRENT THERAPY: Biologic therapy: - Not specified Chemotherapy: - Not specified Endocrine therapy: - Not specified Radiotherapy: - Not specified Surgery: - See Disease Characteristics - No other surgery that would preclude study participation Other: - No other medical treatment that would preclude study participation
