An Open Label, Multi-center, Phase 3 Study With Corresponding Blinded Image Reading to Determine the Efficacy and Safety of a Single Intravenous Injection of 0.1 mmol/kg Body Weight of Gadobutrol 1.0 Molar (Gadovist®) in Patients With Newly Diagnosed Breast Cancer Referred for Contrast-enhanced Breast MRI

Inclusion Criteria:

- Recent histologically proven diagnosis of breast cancer after having obtained X-Ray
Mammography (XRM) of both breasts (according to American College of Radiology [ACR]
and performed no longer than 6 weeks prior to enrollment into the study) and has been
referred for a contrast-enhanced Magnetic Resonance Mammography (MRM) prior to
surgery of the breast.

- if female, a digital XRM is required if any of the following criteria is met:

- a. patient is younger than 50 years;

- b. patient has heterogeneously or extremely dense breasts;

- c. is not post-menopausal (post-menopause defined as at least 12 months prior to
inclusion without menstruation).

- if female of childbearing potential, MRM should be performed on the 7-14th day of the
menstrual cycle.

- has an estimated glomerular filtration rate (eGFR) value >/= 60 mL/min/1.73m2 derived
from a serum creatinine result within 2 weeks prior to study enrollment.

Exclusion Criteria:

- is a female patient who is pregnant or lactating

- has any contraindication to the MRM examination (e.g. metal implants, phobia) or the
use of gadolinium-containing contrast agents.

- has received any contrast agent within 24 hours prior to the study MRM, or is
scheduled to receive any contrast agent within 24 hours after the study MRM.

- has severe cardiovascular disease (e.g., known long QT syndrome, acute myocardial
infarction [< 14 days], unstable angina, congestive heart failure New York Heart
Association class IV) or acute stroke (< 48 hours)).

- has acute renal insufficiency of any severity due to hepato-renal syndrome or in the
peri-operative liver transplantation period or who has acute or chronic moderate or
severe renal insufficiency (glomerular filtration rate < 60 mL/min/1.73m2).

- has received chemotherapy or hormonal therapy for breast cancer within 6 months.

- has received hormone replacement therapy within 4 weeks prior to study drug
administration.

- is scheduled or likely to require a surgery and/or biopsy in the time period up to 24
hours following study drug application

- has prior excisional biopsy or breast surgery less than 6 months before enrollment
and between XRM and study MRM
