Invasive Lobular Carcinoma (ILC)
Invasive Lobular Carcinoma (ILC)
What is Invasive Lobular Carcinoma (ILC)?
Invasive Lobular Carcinoma (ILC) is a type of breast cancer that forms from the lobules, the glands that produce milk, and spreads to the surrounding tissues. It is the second most common type of invasive breast cancer.

What are the symptoms of ILC?
Most cases of ILC don't present obvious symptoms, but ILC may present with:
- Unusual Breast Thickening: ILC can cause an area of thickening in the breast, rather than a distinct lump.
- Changes in Breast Appearance: Changes in the size, shape, or appearance of the breast.
- Nipple Inversion: The nipple may become inverted or change in appearance.
- Skin Changes: Redness, dimpling, or other changes to the skin over the breast.
Risk Factors
A risk factor is something that increases the chance of developing a disease. The following are potential risk factors for breast cancer:
- Age: Higher risk as age increases.
- Family History: A family history of breast cancer, especially ILC.
- Genetic Mutations: Mutations in genes such as CDH1 or other breast cancer genes like BRCA1 and BRCA2.
- Hormonal Factors: Long-term use of hormone replacement therapy (HRT) during menopause.
How is ILC diagnosed?
The following are ways ILC can by diagnosed:
- Physical Exam: ILC may presents as a thickening or hardening in the breast rather than a distinct lump, which can make it more challenging to detect through physical exam alone.
- Mammogram and Ultrasound: These imaging techniques are used to identify abnormal areas in the breast tissue. However, ILC can sometimes be more difficult to detect via mammogram compared to other types of breast cancer because it tends to grow in a more dispersed pattern.
- MRI: Magnetic Resonance Imaging (MRI) may be useful in detecting and assessing the extent of ILC.
- Biopsy: A definitive diagnosis is made through a biopsy, where tissue samples from the breast are examined under a microscope.
How is ILC treated?
Treatment for ILC often involves a combination of methods:
Surgery
- Lumpectomy: Removal of the tumor and a small margin of surrounding tissue.
- Mastectomy: Removal of the breast, especially if the ILC is widespread.
Radiation Therapy
Often recommended after lumpectomy to reduce the risk of recurrence. Radiation is sometimes also recommended after mastectomy in select situations. Learn more about radiation therapy and breast cancer.
Chemotherapy
May be recommended depending on the stage and specific characteristics of the cancer. Learn more about systemic therapies and breast cancer.
Hormonal Therapy
Since many ILCs are hormone receptor-positive, treatments like tamoxifen or aromatase inhibitors may be used to block the cancer's access to estrogen.
Targeted Therapy
Depending on specific molecular characteristics of the cancer, drugs targeting those pathways may be used.
Prognosis
The prognosis for ILC depends on various factors, including the cancer's stage at diagnosis, the tumor size, the cancer's hormone receptor status, the patient's overall health, and response to treatment. Generally, early-stage ILC has a favorable prognosis with appropriate treatment.
Follow-Up Care
Regular follow-up care, including physical exams, imaging tests, are crucial to monitor for any signs of recurrence and manage any long-term side effects of treatment.
Resources and Support
The psychosocial impacts of breast cancer are profound and multifaceted, necessitating a comprehensive approach to care that addresses emotional, psychological, and social needs. At the Weiser Family Center for Breast Cancer, we understand by leveraging a range of support services and resources, breast cancer patients can better cope with their diagnosis, treatment, and post-treatment phases, enhancing their overall quality of life.
