Invasive lobular Cancer (ILC) is diagnosed by the 'Triple Test Score'. This includes :
(b) Imaging of the breast through mammography or ultrasound and/or MRI
(c) Non-excisional biopsy of the suspicious area - this includes both fine needle aspiration cytology and core biopsy.
The triple test is considered positive if any one of the three component is indeterminate, suspicious or malignant. This will then merit further investigations.
For ILC to be ruled out, all three parts of the triple test must be definitely benign.
Diagnosis of Invasive Lobular Cancer
The Breast Cancer Risk Assessment Tool (BCRAT) can be used by health personnel to assess a women's risk of getting invasive breast cancer over a 5-year period of time and up to age 90 (lifetime risk).
A detailed history of any thickening of the breast or pain or lump - how long it has been present, whether painful, any changes since first noted, relation to the menstrual cycle, presence of lumps elsewhere specially in the armpit or neck - should be noted down.
Mammography and ultrasound are often used in a complementary capacity to give more detailed information in the evaluation of normal breast anatomy as well as breast abnormalities.
A breast MRI is mainly used in women who have been already been diagnosed with breast cancer, to help measure the size of the cancer, look for other tumors in the breast and to check for tumors in the opposite breast.
For certain women at high risk for breast cancer, a screening MRI is recommended along with a yearly mammogram.
MRI is not recommended as a screening test for women at average risk of breast cancer since it is known to give some false positive results.
