Diagnosing invasive lobular carcinoma
Tests and procedures used to diagnose invasive lobular carcinoma include:
- Mammogram. A mammogram creates an X-ray image of your breast. Invasive lobular carcinoma is less likely to be detected on a mammogram than other types of breast cancer are. Still, a mammogram is a useful diagnostic test.
- Ultrasound. Ultrasound uses sound waves to create pictures of your breast. Invasive lobular carcinoma may be more difficult to detect with ultrasound than may other types of breast cancer.
- Magnetic resonance imaging (MRI). MRI uses a strong magnetic field to create a picture of your breast. A breast MRI may help in evaluating an area of concern when mammogram and ultrasound are inconclusive. It can also help determine the extent of the cancer within your breast.
Removing a sample of tissue for testing. If an abnormality is detected, your doctor may recommend a biopsy procedure to remove a sample of suspicious breast tissue for laboratory testing.
A breast biopsy can be done using a needle to draw out fluid or tissue from the breast, or breast tissue can be removed surgically.
Determining the extent of invasive lobular carcinoma
Once it's determined that you have invasive lobular carcinoma, your doctor will determine if additional tests are needed to learn the extent, or stage, of your cancer. Most women do not require additional tests other than breast imaging, physical exam and blood tests.
Depending on your situation, your doctor may recommend imaging tests to stage your breast cancer, such as magnetic resonance imaging (MRI), among others.
Using this information, your doctor assigns your cancer a Roman numeral that indicates its stage. Breast cancer stages range from 0 to IV, with 0 indicating cancer that is very small and noninvasive. Stage IV breast cancer, also called metastatic breast cancer, indicates cancer that has spread to other areas of the body.
