| Breast Lump (Malignant) |
Breast cancer is the most fre¬quently diagnosed cancer and the chief cause of cancer death among women worldwide, with an es¬timated 1.7 million cases.
Breast cancer alone accounts for 25% of all cancer cases and 15% of all cancer deaths among females .so, Its high incidence has led to research on new diagnostic imaging techniques for early diagnosis and to improve patient's mortality rate[1].
Application of imaging techniques together with other investigation would help clinical decision making. the most important factor in reducing mortality of certain cancers is an early diagnosis of cancer via screening based on imaging[2].
US is an accurate method for detection of breast masses ; however, US has a low accuracy in differentiating between benign from malignant breast masses . US could suggest a malignancy likelihood criteria of a breast mass, such as hypoechogenicity, irregular margins, microcalcifications, increased vascularity by Doppler and us elastography [3].
Ultrasound elastography provides a non-invasive evaluation of the "stiffness" of a lesion. Recent studies show that ultrasonographic elastogra¬phy (USE) provides higher diagnostic accuracy together with Doppler application compared with conventional B-mode ultrasonography during breast cancer diagnosis, which eventually helps to reduce false-positive results (ie, increased specificity) and therefore is useful in avoiding breast biopsy[4].
US elastography has been used to detect the nature of breast lesions , by measuring the tissue stiffness non invasively. It depends on tissue deformation strain that is caused by external compression. it is complementary to gray scale findings particularly in lesions with indeterminate US findings, also US elastography could be used to guide the follow up of leisons diagnosed as benign at ( FNA) fine needle aspiration.[5][6]

| Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
| Sexes Eligible for Study: | All |
| Accepts Healthy Volunteers: | No |
| Sampling Method: | Non-Probability Sample |
All patients will subjected to :
Full history taking, clinical examination by referring physician . Then the patient will be examined by Gray scale US , doppler and elastography at Radiology department.
On Gray scale:Echogenicity of the mass with respect to normal breast parenchyma, diameter A/T ,margins and calcifications.
While on Color Doppler, to describe the vascular patterns. Masses and axillary lymph nodes (if detected) will be identified as nonvascular or vascular (peripheral, central, or mix).
(A) Strain elastography Color coding is classified into 5 groups according to the Ueno classification, score one (softest component) and score five (hardest component) .
(B) Shear wave elastography A ROI rectangular box was adjusted on the observed target lesion including sufficient amount of surrounding healthy breast tissue.
Inclusion Criteria:
- patients with breast masses referred to our department of diagnostic radiology for radiological assessment.
Exclusion Criteria:
Patients with purely cystic lesions on conventional breast ultrasound. Breast implant. Superficial lesions (>5 mm deep to skin surface).
