DNA Microarrays Technology
hybridization between two DNA
strands, the property of
complementary nucleic acid
sequences to specifically pair with
each other by forming hydrogen
bonds between complementary
nucleotide base pairs.
Staging and grading
Investigations
Mammogram
MRI
Screening high-risk women
Gathering more information about an area of suspicion
Monitoring treatment
Ultrasound
Usually after mammogram
Detect abnormality type
Before mammogram to
evaluate lump
Biopsy

Core needle biopsy
Vacuum-assisted breast biopsy (guided)
Surgical Biopsy
Blood tests
