Digital Mammography and Diagnostics

Early detection through mammography can offer the best chances of survival. That’s why we offer a full range of state-of-the-art breast cancer diagnostic services including:

  • 3D Mammography Technology that increases accuracy and improves chances of early cancer detection. Available only at Dyson Breast Center at Vassar Brothers Medical Center.
  • Digital Mammography, with its exceptional clarity and accuracy, can detect breast tumors earlier, allowing for treatment to begin sooner.
  • Stereotactic Breast Biopsy is a procedure performed by radiology in the radiology suite using specially designed equipment that allows for examination of breast tissue. Small samples of tissue are extracted through a biopsy needle for pathology to review.
  • MRI and Ultrasound Imaging can scan any angle of the body to create clear, highly detailed images. To learn more about these services, see Women’s Imaging.
  • Genetic Screening for patients with cancer or a family history of breast or ovarian cancer to test for the BRCA1 and BRCA2 genes and assess risk. To learn more about these services, see Genetic Counseling.

Advanced Surgical Options

If surgery is deemed necessary, you can rest assured you are in great hands. The surgical team specializes in breast procedures including:

  • Sentinel Lymph Node Biopsy is the surgical removal of lymph node(s) for pathology to review. This type of biopsy is used to determine if cancer cells from the breast tumor have spread. This biopsy is usually done at the same time as the surgery to remove the tumor.
  • Partial Mastectomy involves removal of the tumor along with a rim of normal tissue known as the margins. This procedure is often performed in conjunction with a sentinel lymph node biopsy.
  • Total Mastectomy involves removal of the entire breast, including the nipple and areolar complex.
  • Modified Radical Mastectomy involves removal of the entire breast, including the nipple, areolar complex and most of the lymph nodes from the armpit.
  • Radical Mastectomy involves removal of the entire breast, including the nipple, areolar complex, lymph nodes and chest wall muscles.
  • Skin Sparing Mastectomy with Immediate Reconstruction removes the breast tissue, but leaves the outer skin. If the tumor does not involve the skin, plastic surgeons then perform breast reconstruction during the same operation.
  • Nipple Sparing Mastectomy with Immediate Reconstruction removes the breast tissue leaving the outer skin and nipple areola complex. A plastic surgeon* then immediately performs reconstruction. This can be done for cancer and prophylactic surgeries.

Breast Reconstruction

With great strides in breast reconstruction procedures, we are proud to help many patients recapture the body they had before cancer. The team carefully assesses each patient to ensure she is a good candidate for this type of surgery.

Breast reconstruction is frequently performed during the same operation that removes the tumor, but can also be scheduled for later. These are the main procedures used with plastic surgery:

  • Oncoplastic surgery occurs after a lumpectomy or partial mastectomy. It involves rotating native breast tissue to fill the cavity left behind after tumor excision. This yields a better cosmetic outcome.
  • Tissue Expanders/Implants occurs after skin or nipple sparing mastectomy. A tissue expander allows expansion of the skin envelope over time and eventual exchange for an implant during a later operation. Some patients may not require expansion and have a breast implant placed at the time of mastectomy.
  • TRAM (Transverse Rectus Abdominus Myocutaneous) flap technique uses muscle, fat and skin from the lower abdomen to create a new breast mound after a mastectomy. It requires a second surgery to create a new nipple and areola.
  • LATIS (Latissimus Dorsi) flap technique rotates the upper back muscle to the front of the chest to form a new breast mound. This flap is useful in patients who have had prior abdominal surgery or in patients requiring chest wall radiation.
  • DIEP (Deep Inferior Epigastric Perforators) flap technique uses skin and fat from the abdomen to reconstruct a natural-looking, natural-feeling breast without the use of implants or abdominal muscle. Since muscle is not removed, there is generally less pain and faster recovery compared to traditional reconstruction techniques.

Radiation Therapy

Using the most advanced equipment, our radiation oncologists can precisely target the cancerous area while minimizing impact on the surrounding healthy tissue. This increases the chances for success and can lead to a quicker recovery. Your radiation oncologist* will discuss the best course of treatment for your situation.

Three types of radiation therapy are commonly used to treat breast cancer:

  • Intraoperative therapy is used in the operating room during surgery, especially for breast cancer. In this therapy, a small machine provides low-energy radiation to a specific target exposed during surgery.
  • External beam radiation therapy directs a beam of radiation at the cancerous area to destroy the tumor and any nearby cancer cells. The team can control the size and shape of the beam, as well as how it is directed at the patient’s body. This treatment spares surrounding normal tissue.
  • Brachytherapy (or internal radiation therapy) involves placing a radioactive seed in or very close to the tumor, allowing the radiation oncologist to deliver a large dose of radiation directly to the cancerous cells with minimal impact on the surrounding tissue.


Chemotherapy is the use of medication to destroy cancer cells. Some medications are in liquid form and are given through a needle. Others are taken in pill form. Medical oncologists work closely with surgeons and radiation oncologists to optimize each patient’s therapy.

The two most common therapies used to treat breast cancer are adjuvant (after surgery) and neoadjuvant (before surgery):

  • Adjuvant Therapy is designed to increase the chance of long-term survival by treating cancer cells that may have spread outside the breast. Patients determined to be at significant risk of future cancer recurrence are often treated with this therapy.
  • Neoadjuvant Therapy is designed to shrink the tumor to improve the chances of breast conservation during surgery. A patient may also receive this treatment to shrink a tumor that is inoperable in its current state, so it can be surgically removed.

Fertility Preservation

Breast cancer patients often require adjuvant therapy following surgery, which commonly affects fertility and may cause premature ovarian failure.

For women interested in future pregnancy, Health Quest offers options to help preserve their fertility during cancer treatment. These include ovarian stimulation, embryo/oocyte cryopreservation and ovarian tissue cryopreservation. Please speak with your physician to determine if a consultation with a specialist is needed.

Rehabilitation and Nutrition

To help patients recover faster, our post-operative rehab program includes education about sensations, scar management, lymphedema risk reduction management and a customized exercise program. Our Lymphedema Remediation program is led by a certified lymphedema therapist who teaches manual lymph drainage, compression, bandaging, skin care and exercise. Our program also includes access to cosmetics, wigs and post-mastectomy items.

In the event that a patient develops lymphedema, certified lymphedema therapists are available at all of our Health Quest locations. Several lymphedema therapists have received the distinction of LANA (Lymphology Association of North America) certification.

Oncology-focused registered dietitians are available to help breast cancer patients maintain good nutrition to stay strong and energetic during treatment. Dietary changes may help.
