Cryoablation vs Lumpectomy in T1 Breast Cancers

This study compares two treatments for small breast cancers: cryoablation (freezing the tumor to destroy it without surgery) versus lumpectomy (traditional surgical removal). The goal is to see if freezing the tumor is just as effective as cutting it out. **You may be eligible if...** - You are at least 50 years old - You have been diagnosed with a small invasive ductal breast cancer (2 cm or smaller, ER-negative and HER2-negative, grade 1 or 2) - Your cancer has not spread to lymph nodes or other organs (T1N0M0) - Any pre-cancerous component (DCIS) makes up less than 25% of the tumor - You are willing to have either cryoablation or lumpectomy **You may NOT be eligible if...** - Your tumor is larger than 2 cm - Your cancer has spread to lymph nodes - Your tumor has a large pre-cancerous component (more than 25%) - You have inflammatory or multi-focal breast cancer - You have a pacemaker or implanted device that would prevent MRI Talk to your doctor to see if this trial is right for you.
