Ductal Carcinoma In Situ is a Non Invasive Stage 0 Breast Cancer -
Twenty Percent May Become An Invasive Cancer

Ductal Carcinoma In Situ presents itself within the milk ducts and can extend in a variety of directions.

The unpredictable nature of Ductal Carcinoma In Situ both microscopically, and in the range where this potential pre-cancer can extend through the ducts, needs to be surgically optimized with an advanced level of technological capability. This factor alone makes The Ansanelli Co2 Laser Technique a highly beneficial option to the DCIS patient. The Ansanelli Co2 Laser Technique uniquely achieves this with its beam of light immediately sealing and sterilizing the smaller blood vessels and lymphatics during dissection. This preventative process dramatically reduces the level of cell spread and seeding of cells that is typically presented with knife and cautery methods- hyperlink to knife cautery page. There is no residual tissue damage remaining (cautery/knife methods) or dead cells for the body to reabsorb (ablation methods). With the elimination of these typical factors, there is a painless, immediate tissue recovery for the patient. The Ansanelli Co2 Laser Technique dramatically reduces the risk of infection and complication.

Additionally, this clean and finite process of removal provides Dr. Ansanelli with the capability of targeting the DCIS region more specifically. This is especially beneficial for patients having breast conservation surgery (lumpectomy- hyperlink to lumpectomy page or partial mastectomy. Upon removal of the specified DCIS region, Dr. Ansanelli provides his patients with another extra step during surgery by sealing and sterilizing the tissues with the laser without dissecting any further. This process eliminates any remaining pre-cancerous cells in the surgical field and provides an extra benefit addressing the unpredictable nature of DCIS. Dr. Ansanelli does not utilize any needles or other modalities (like with laser ablation) to sample tissue for analysis. The entire region is removed in a complete excision with these sealing and sterilization features. Animal studies have demonstrated 80% less local recurrence- hyperlink to animal study with the Co2 laser. Understanding the cell activity associated with DCIS this feature is extremely beneficial to the surgical patient in keeping the area contained. Many of Dr. Ansanelli’s patients have been cancer-free longer than the national average.

The tissue is then immediately sent to a state accredited laboratory for pathological analysis to confirm cancer free margins. Dr. Ansanelli then provides a plastic repair with the laser, utilizing the remaining healthy breast tissue to reshape the breast. Overall, The Ansanelli Co2 laser technique provides the highest level of technology, and surgical application to protect the patient in surgery and in preventative care.

Core needle biopsy is the most common method of diagnosing DCIS. This puts the patient at tremendous risk of 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 cell spread as the laser is sterilizing and sealing the smaller blood vessels and lymphatics during removal. Animal studies have demonstrated 80% less local recurrence. The laser’s finite incisions are painless, without post-operative complications all while not jeopardizing the safety of the patient.
