Nurse Navigator Program

A diagnosis of cancer is often devastating to a patient and their family. Our nurse navigator program pairs a certified oncology nurse with a patient to help coordinate care throughout diagnosis, treatment and recovery. After the doctor explains the treatment plan, the nurse navigator reviews it with the patient to be sure all questions are answered. Then she remains in regular contact with the patient. In fact, patients can call their nurse navigator with questions or concerns around-the-clock at any point during their cancer experience.

The Nurse Navigator

  • Is an R.N. who is certified in oncology, experienced in working with oncology patients and has compassion that runs deep
  • Helps patients understand the diagnosis and treatment plan
  • Watches closely for any problems that may arise over the course of treatment and recovery
  • Serves as a clinician, care coordinator, educator and counselor for patients and families
  • Improves patient outcomes through education, support and monitoring
  • Coordinates care with other healthcare providers, such as pharmacists, dieticians, social workers, case managers and counselors
  • Helps the patient and family connect with community resources
  • Remains in contact with the patient throughout the treatment process; the patient may call at any time with questions about medication, symptoms, lifestyle changes or other concerns

"As an oncology nurse navigator for breast cancer patients, I am available for my patients for any questions, concerns or problems that may arise during their journey. The diagnosis of cancer is a scary, confusing time, and the nurse navigators are here to hold the patients hand and walk with them and their family through this trying time. Patient care is coordinated at the multidisciplinary meeting with the surgeon, medical oncologist and radiation oncologist, along with discussion with the radiologist and pathologist. When the team goes to meet the patient and discuss their care, they go as a united front after having the team discussion. The nurse navigator then meets with the patient at the end to tie up any loose ends, provide education, and most importantly, to answer any questions the patient may have and let them know that we are available at any time. I am honored to be a nurse navigator and to have the privilege to help patients at a time when the system can become confusing."

In particular, I work with cancer control clinical trials, which deal with the side effects of cancer or its treatments, such as pain management, fatigue, and ways to improve comfort and quality of life during and after cancer treatment. I also work with clinical trials that aim to prevent cancer by involving people that do not have cancer but have known risk factors for cancer development, as well as cancer survivors to prevent a second cancer.  I enjoy working with patients to assure a positive experience while navigating them through our healthcare system and clinical trial. I am excited about the aims of these trials to improve the quality of life in people undergoing cancer treatments and survivors, as well as the potential to unveil strategies to prevent cancer."
