Nurse Navigator Program

Through the Nurse Navigator program, cancer patients at the MDC have a personal guide to lead them through diagnosis and treatment. A diagnosis of cancer is often devastating to the patient and family. Our Nurse Navigator program pairs a certified oncology nurse with a patient who has cancer 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 anytime day or night at anytime during their cancer experience.

The Nurse Navigator

  • Coordinates care with other healthcare providers such as pharmacists, dieticians, social workers, case manager and counselor
  • 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 day or night with questions about medication, symptoms, lifestyle changes or other concerns.

Oncology Nurse Navigators


Jo Maria Weathers RN, BSN, OCN, CBCN

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.  The patients’ 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, to do education and most important to answer any questions and let the patient know that you are available for any questions or concerns 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.

As an Oncology Clinical Research Nurse I work with physicians, patients, and the community to navigate people through clinical trials.  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 treatments.  I also work with clinical trials that aim to prevent cancer by involving people that do not have cancer but have known risk factors that put them at risk for cancer development and cancer survivors to prevent a second cancer after completion of cancer treatments for a previous 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.
