My sister in law has two clusters of microcalcifications in one duct. There is a great amount of cancer in the family including her mother who had breast cancer. She is obviously concerned about the results of her mamogram which found her cluster to be a BIRAD 4. She found a doctor in ny that uses laser for surgical treatment of breast cancer, DCIS, microcalcifications etc. He uses laser for procedures such as lumpectomy, mastectomy, etc. She is considering using this doctor but she is concerned about why more doctors don't use laser. Does anyone have information on why laser is not more commonly used?
