One Day Breast Diag

A personalized pathway to make a very rapid diagnosis in the event of a clinical anomaly or abnormal imaging result

The American Hospital of Paris helps women reduce the anxiety-inducing wait time for diagnosis and results.

When a self-exam or mammogram reveals an anomaly or suspected breast cancer, waiting for the next exams can be a long and stressful period.

Our complete breast diagnosis, which only takes a half-day, is designed for:

  • „Patients with a symptom affecting the breast, such as a lump, discharge or inflammation, detected through a self-exam or by a doctor
  • „Patients with an anomaly detected through imaging or a clinical exam
  • „Patients who would like a second diagnostic opinion

With a very quick appointment, the One Day Breast Diag program makes it possible to have a diagnosis in half a day, in most situations, to determine the nature of the abnormality observed. If the patient wishes and if it proves necessary, a course of treatment can be organized in a very short time.

The One-Day Breast Diagnosis, which can be scheduled with little to no delay, allows most patients to receive a diagnosis revealing the exact nature of their anomaly in just one half-day. When necessary, treatment can be organized very rapidly, if desired by the patient.
Results are provided to the patient the same day.

A personalized extremely rapid diagnosis to quickly eliminate any uncertainty

The One-Day Breast Diagnosis is designed to facilitate the care pathway for women and bring reassurance when they are faced with a suspicious anomaly. It eliminates the waiting periods for appointments and exam results, which cause anxiety and may delay the beginning of treatment.

All throughout the half-day visit, the patient is supported by a coordinating nurse and a volunteer. She may also be accompanied by the person of her choice, except during the exams, when that person will be asked to remain in the waiting room.

This approach to patient support is core to the American Hospital of Paris’s caregiving philosophy.

Full diagnosis in one half-day

  • 1- in a single, dedicated location

    The entire procedure takes place in a single, dedicated location guaranteeing privacy and confidentiality.

  • 2 - During a consultation with an oncologist specialized in breast pathologies,

    information is collected about the patient’s current breast problem as well as her personal, gynecological and family medical history, treatments such as hormone replacement therapy and contraception, and other individual risk factors. All previous medical documents and exam results are reviewed.

    The oncologist performs a clinical exam with special focus on the breasts and lymph nodes (axillary and supraclavicular). At this stage, he or she will decide which additional tests should be performed that day to complete the diagnosis and may also explain the various diagnostic hypotheses.

  • 3 - Radiological workup and analysis

    any previously performed imaging exams are reviewed. A mammogram and breast ultrasound are performed if they were not previously done or if additional information is needed.

    If indicated, fine-needle aspiration and/ or biopsy is performed in the presence of an anatomical pathologist. The sampling technique enables a rapid interpretation of the result.
    A breast MRI and other additional tests may be scheduled if necessary.

  • 4 - Specimens are analyzed

    by the anatomical pathologist. Rapid interpretation revealing whether or not tumor cells are present is only possible for fine-needle aspiration. If a biopsy is performed, results are delivered during a second appointment, 24 to 48 hours later.

  • 5 - A multidisciplinary team meeting

    Before the results are announced, a multidisciplinary team meeting takes place between the radiologist, the anatomical pathologist and the oncologist in order to reach a diagnostic consensus and ensure all test results are concordant.

  • 6- Once the results are announced,

    the different treatment options are explained and, if the patient wishes, organized.

    If surgery is being considered, the patient sees a specialist surgeon the same day and surgery can be scheduled within a very short timeframe.

    If the result is benign, recommendations for surveillance and subsequent monitoring are given, and the necessary appointments can be scheduled immediately.

    Lastly, a detailed report is provided to the patient and to the various physicians in charge of her care.
