Ductal Carcinoma Insitu is a type of noninvasive breast condition in which twenty percent may become an invasive cancer. DCIS presents itself within the milk ducts and can extend in a variety of directions.

Dr. Ansanelli’s laser surgery serves as a tremendous benefit to a DCIS patient as it greatly reduces the chance of cancer cell spread. Scientifically, while the fine beam of light is dissecting and removing the tissue for pathology, it vaporizes and sterilizes the surrounding area. More importantly the laser creates a cellular reaction creating a barrier, reducing the level of cancer cell spread. The knife/scalpel cuts spreading the potential cancer cells and the cautery burns tissue complicating the recovery process. This method creates pain and increases chance of infections.

Understanding the unpredictability of DCIS and the range it can extend, it is very important that the microscopic cellular involvement is tested pathologically. Insitu ablation does not have this capability as it is ablating the cells within the body and using needle biopsy as the means of tissue diagnosis. The Ansanelli laser technique removes the DCIS enabling pathological analysis while sealing the area reducing cancer cell spread while providing confirmation of clear margins.

Core needle biopsy is the most common method of diagnosing DCIS. This puts the patient at tremendous risk of cancer cell spread. The multiple insertions of large core needles into the breast, in efforts to obtain sufficient sampling of the suspicious region, enables the cells to escape through the blood stream. Core needle biopsies also have its list of complications such as pain, and hematomas. Dr. Ansanelli’s laser technique greatly reduces the chance of cancer cell spread as the laser is sealing the smaller blood vessels, and lymphatics during removal. The laser’s finite incisions are painless, without post-operative complications all while not jeopardizing the safety of the patient.


Dr. Ansanelli is best known for his pioneering work in minimally invasive breast cancer surgery, including an improved method of cosmetic laser surgery, is a board certified surgical oncologist. Knowledge leads to innovation. Dr. Ansanelli’s approach to breast cancer includes a rare combination of abilities in open breast surgery utilizing lasers to improve standard surgical techniques. His prospective randomized published studies on the advantages of laser surgery over scalpel surgery led to benefiting thousands of breast surgical patients. In mastectomies these advantages included a more cosmetic result, a finer incision, no sutures to be removed, less drainage, no general anesthesia, no post-operative medications. His patients most times have an improved cleavage when possible instead of depressed cavities. The advancements also include the ability of the patient to leave his facility within 30-45 minutes without pain. His patients are able to resume some activities on the surgical day. The Ansanelli technique is the only breast surgical procedure to sterilize the surgical bed. This sterilization contributes to curtailing future recurrences on the chest wall. Dr. Ansanelli personally performs each procedure with the same team. His facility offers a sterile atmosphere without endangering the clean cases of breast cancer with the exposure to contaminated bacterial & viral cases in a general hospital. He is very proud of his staff & team. Dr. Ansanelli states “We are all after the same thing outstanding outcomes for our patients.”


This procedure as in every level of laser surgery, eliminates the need for any general anesthesia or hospitalization. The laser does more than purely remove the lump. It seals the surrounding blood vessels and lymphatics thereby decreasing the blood loss and potential tumor cell spread. Many of my patients have opted for laser surgery over core biopsies and knife surgery for these reasons. Lasers also provide the added benefit with small cosmetic incisions in the majority of cases. The lump is sent to the laboratory for pathological analysis.

Core Biopsy for Micro and Tumor

In the process of core biopsies, there is a potential risk in the spread of cancer cells. It has been my experience for treating breast cancer for thirty years that sealing lymphatic, blood vessels and surrounding tissue while moving the area in question, helps eliminate the potential spread of cancer.
