LCIS is often __ and __ on initial diagnosis. - ANSWERS-Often
bilateral and multicentric
Microcalcifications are ___ with LCIS. - ANSWERS-Uncommon
LCIS is best diagnosed by ___. - ANSWERS-- Neither
mammography no sonography.

Name 6 types of invasive carcinomas of the breast. - ANSWERS--
Invasive ductal carcinoma
- Invasive lobular carcinoma
- Medullary carcinoma
- Colloid (mucinous) carcinoma
- Tubular carcinoma
- Papillary carcinoma
,What is the most common form of breast cancer overall? -
ANSWERS-- Invasive ductal carcinoma (IDC) is the most common
from of breast cancer
- It makes up approximately 75% of all breast cancers.
- IDC arises from the epithelium of the duct and invades through the
basement membrane into the surrounding tissues.
Name several classical clinical features of invasive ductal carcinoma
(IDC) - ANSWERS-- Palpable mass
- Hard, gritty texture
- Tumor is fixed (immovable)
- Skin dimpling, skin retraction, or nipple retraction
How does invasive ductal carcinoma (IDC) appear on sonography? -
ANSWERS-- IDC has all of the common features of malignancy.
- Solid mass
- Irregular shape with angular or spiculated margins
- Taller than wide
- Markedly hypoechoic
- Heterogeneous internal appearance
- Partial or complete shadowing
- Duct extension or branch pattern
- Retracted cooper's ligaments
- Fascia plane disruption
,What is the most frequently missed breast cancer? - ANSWERS-
Invasive lobular carcinoma (ILC)
What characteristics make it difficult to detect invasive lobular
carcinoma (ILC)? - ANSWERS-ILC is usually :
- non-palpable
- does not have microcalcifications
- tumors are highly infiltrative and aggressive
- it may produce an area of architectural distortion without a mass
- It is easily missed by mammography and sonography.
How often does invasive lobular carcinoma (ILC) occur? -
ANSWERS-- ILC is the second most common type of invasive breast
cancer.
- It accounts for 8-15% of cases.
What type of breast cancer is most frequently mistaken for a benign
fibroadenoma? - ANSWERS-Medullary carcinoma
What characteristics of medullary carcinoma make it difficult to
distinguish? - ANSWERS-- Presents as a well- circumscribed, soft
tumor.
- It is non-tender, compressible, and slightly movable.
- It is not associated with microcalcifications and has a homogeneous,
hypoechoic appearance with no shadowing on sonography.
, What type of breast cancer is relatively common in young women? -
ANSWERS-- Medullary carcinoma
- Represents 11% of breast cancers found in women under 35.
- It makes up approximately 5% of invasive cancers in women of all
ages.
- More common among Asian and African-American women.
Name the type of breast cancer that contains a gelatin or syrup like
interior. - ANSWERS-- Colliod carcinoma
- Tumor containing mucous-producing cancer cells that creates a
gelatin like interior.
- It is a slow growing tumor that typically affects elderly women.
How does colloid carcinoma appear on sonography? - ANSWERS--
Hypoechoic or isoechoic
- Well-circumscribed
- Homogeneous internally
- Shadowing is uncommon
- May appear similar to a complicated and/or complex cyst
Papillary carcinoma represents the malignant version of an intraductal
papilloma. What age group is generally affected by papillary
carcinoma? - ANSWERS-Primarily postmenopausal women
LCIS is cancer confined to __. - ANSWERS-Lobule
LCIS ___ present as a palpable mass. - ANSWERS-Does not
