Breast Cancer Surgery

Breast cancer surgery is a medical procedure performed to remove cancerous tissue from the breast, typically through lumpectomy (removal of the tumor and surrounding tissue) or mastectomy (removal of the entire breast), aiming to prevent cancer from spreading or recurring.

Mastectomy Surgery

Mastectomy surgery is a procedure in which the entire breast, including the tumor and surrounding tissue, is removed in order to treat or prevent breast cancer, often followed by reconstructive surgery to restore the breast's appearance.

Lumpectomy Surgery

Lumpectomy surgery is a breast-conserving procedure that involves removing a cancerous tumor and a small margin of surrounding healthy tissue, aiming to preserve the majority of the breast while effectively treating breast cancer.

Specializing in Breast Cancer Treatments, helping thousands of breast cancer patients fight and eliminate their breast cancer for good.

You don’t fight breast cancer alone, Dr. Bertoni is here for you to help with you fight against cancer.

Danielle Bertoni, MD, MPH, is a breast surgeon at BASS Cancer Center who specializes in breast surgical oncology.

She has a reputation for using breast conservation techniques, performing nipple-sparing mastectomies and a wide range (and type) of breast biopsies and surgery for benign conditions, such as fibroadenomas and atypia, with successful cosmetic results. She also has expertise in management of the axilla and is passionate about reducing long term complications and focusing on survivorship.

Dr. Bertoni’s mother, grandmother, aunt and cousins have all had breast cancer, and that helped inspire her to become a breast surgeon. “I wanted to be in a field where I could help women get through this difficult time in their lives with as much comfort, reassurance and ease as possible. I wanted to be there to ‘hold their hand’ through the process,” she says.

Dr. Bertoni believes in making the patient the central focus of a team of doctors, nurses, social workers and other providers. Highly personalized care is important, she says, adding that she takes into account not only the patient’s diagnosis, but also their personal values and beliefs while guiding them through the process. “I take ownership of my patients,” she says. “This is a long-term relationship.”

Dr. Bertoni is passionate about providing the highest quality, most up to date and timely care to all of her patients. She supports participation in clinical trials if patients desire and will help patients with this. She is passionate about continuing to improve care and outcomes for patients with breast cancer. She is also an expert in caring for high risk patients with family history of breast and ovarian cancer and high risk breast lesions. She encourages all women to be proactive in talking with their doctor about any breast health questions or concerns.

Annual mammograms are key, as are ultrasounds if the doctor recommends them, she says.

Any woman who has multiple family members with breast or ovarian cancer should bring that history to their doctor’s attention, and ask how it might impact their personal risk or eligibility for genetic testing or special screening, she adds.

What Dr. Bertoni's Breast Cancer patients are saying...

"Dr. Danielle Bertoni was the Surgeon for my mom. Dr. Bertoni is the full package when it comes to being a doctor. She's very knowledgeable, personable and professional. She's a good listener and she made sure that we understood the process for surgery and after surgery. When we had questions she made sure that she called us back. This entire experience has been excellent from the front desk to the visit with Dr. Bertoni. My mom and I value and appreciate Dr. Bertoni."

"She was very warm and understanding, she never downplayed what I felt or what I was going through. She was very thorough and explained everything with intricate details. She was very compassionate and very optimistic with the perfect pinch of a realist as well. Overall I felt like Dr. Bertoni treated me with the utmost compassion and respect."

"Dr. Bertoni could be the best, most caring, nicest doctor we've ever worked with. We were presented with a very scary life/death stage 3 cancer diagnoses. Dr Bertoni worked with us day and night keeping us informed and updated as to what we should be expecting. She set our expectations and got us through the toughest experience in our lives. We will never forget her for the rest of our lives. We HIGHLY recommend her."

Cancer care
is essential care

Bass Cancer Center

It took a year before I had the mammogram that I needed. Things could have turned out much different had I kept waiting.

My doctor educated me on everything I needed to know and explained every possible scenario. She was kind and knowledgeable and I could tell that she cared. We hypothesized that the armpit lump was a swollen lymph node, which is usually not a good sign, then I underwent...
