Advanced Breast Cancer Surgery & Multidisciplinary Care
Invasive Lobular Carcinoma (ILC) is the second most common form of invasive breast cancer, accounting for approximately 10–15% of all breast cancer cases worldwide. Although it shares certain features with other invasive breast cancers, ILC has distinct biological behavior, growth patterns, diagnostic challenges, and surgical considerations that make specialized evaluation and treatment essential.
Unlike Invasive Ductal Carcinoma, which often presents as a clearly defined lump, ILC tends to grow in a diffuse, single-file pattern of tumor cells that infiltrate surrounding breast tissue. Because of this subtle growth pattern, it may not always form a palpable mass or show clearly on routine mammography. This makes early detection more challenging and emphasizes the importance of experienced radiological assessment and surgical planning.
At Max Super Speciality Hospital Mohali, Dr. Lovedeep Singh Chauhan provides comprehensive, evidence-based surgical management for patients diagnosed with Invasive Lobular Carcinoma. His approach combines precise oncologic surgery with multidisciplinary coordination to ensure optimal outcomes.
Understanding Invasive Lobular Carcinoma
What is Cervical Cancer?
Invasive Lobular Carcinoma begins in the milk-producing lobules of the breast. Once cancer cells break through the lobular walls, they invade surrounding breast tissue and can potentially spread to lymph nodes or distant organs.
One of the hallmark features of ILC is the loss of a protein called E-cadherin. This protein helps cells stick together. When it is absent, cancer cells grow in a dispersed pattern rather than forming a solid mass. This biological difference influences:
- How the tumor appears on imaging
- How large it actually is compared to what imaging suggests
- Surgical planning strategies
- Patterns of metastasis
ILC is more commonly hormone receptor-positive (estrogen receptor and progesterone receptor positive) and less frequently HER2-positive. These characteristics play a significant role in determining systemic therapy options such as hormone therapy or chemotherapy.
Risk Factors for Invasive Lobular Carcinoma
While the exact cause of ILC is not always identifiable, several risk factors are associated with its development:
Age is one of the most significant factors. ILC is more frequently diagnosed in postmenopausal women. Hormonal influences play a strong role, particularly prolonged exposure to estrogen. Women who begin menstruation early, experience late menopause, or undergo long-term hormone replacement therapy may have increased risk.
A personal history of Lobular Carcinoma in Situ (LCIS) significantly increases the likelihood of developing invasive lobular carcinoma in either breast. Genetic mutations such as BRCA1 and BRCA2 also elevate risk, particularly in individuals with a strong family history of breast or ovarian cancer.
Diagnostic Evaluation and Staging
Accurate diagnosis is the cornerstone of effective treatment. Because ILC may not always appear clearly on standard mammography, advanced imaging is often necessary.
Clinical Examination
A thorough clinical breast examination is performed to assess asymmetry, skin changes, and palpable thickening.
Imaging Studies
Mammography remains the first-line screening tool, but it may underestimate tumor size in ILC. Ultrasound helps evaluate suspicious areas. However, breast MRI is particularly valuable in lobular carcinoma because it provides better visualization of diffuse tumor spread and can detect multifocal or bilateral disease.
Biopsy
A core needle biopsy confirms the diagnosis. The pathology report provides essential details including:
- Tumor grade
- Estrogen receptor (ER) status
- Progesterone receptor (PR) status
- HER2 status
- Ki-67 proliferation index
Staging Workup
Once diagnosed, staging determines whether the cancer has spread. This may include:
- CT scan of chest, abdomen, and pelvis
- PET-CT in selected cases
- Bone scan if symptoms suggest bone involvement
Staging follows the TNM system, evaluating tumor size, lymph node involvement, and distant metastasis.
Symptoms and Clinical Presentation
Invasive Lobular Carcinoma may not present with a distinct lump. Many patients describe a vague thickening or fullness in one area of the breast. Sometimes, the only sign is subtle asymmetry between the two breasts
Possible symptoms include:
- A thickened or hardened area in the breast
- Change in breast size or contour
- Skin dimpling
- Nipple retraction
- Unexplained breast discomfort
- Abnormal findings on screening imaging
Because the signs can be subtle, regular breast screening and timely evaluation of any unusual changes are crucial.
Treatment of Invasive Lobular Carcinoma
Treatment is individualized based on tumor stage, receptor status, patient age, comorbidities, and personal preferences.
Surgical Treatment
Surgery remains the primary treatment for localized ILC. Because of its diffuse growth pattern, careful preoperative planning is critical.
Breast-Conserving Surgery
Also known as lumpectomy, this procedure removes the tumor along with a margin of normal tissue. Due to the infiltrative nature of ILC, achieving clear margins is especially important to reduce the risk of reoperation.
Mastectomy
In cases of large tumors, multifocal disease, or patient preference, mastectomy may be recommended. Immediate or delayed reconstruction options are discussed depending on clinical suitability.
Sentinel Lymph Node Biopsy
This minimally invasive procedure evaluates whether cancer has spread to nearby lymph nodes. If positive, further axillary surgery may be required.
Systemic Therapy
Most ILC tumors are hormone receptor-positive. Hormone therapy plays a central role in treatment. Medications such as tamoxifen or aromatase inhibitors significantly reduce recurrence risk.
Chemotherapy is recommended based on tumor size, lymph node involvement, genomic profiling, and patient-specific factors. HER2-targeted therapy is indicated in HER2-positive cases.
In advanced or metastatic disease, CDK4/6 inhibitors combined with hormone therapy have shown improved outcomes.
Radiation Therapy
Radiation therapy is typically recommended after breast-conserving surgery and in selected post-mastectomy cases. It reduces local recurrence risk and improves long-term disease control.
Unique Characteristics of Invasive Lobular Carcinoma
ILC differs from other breast cancers not only in growth pattern but also in metastatic behavior. It has a tendency to spread to unusual sites such as:
Peritoneum
Gastrointestinal tract
Ovaries
Bone
Additionally, ILC may recur later than ductal cancers. This highlights the importance of long-term follow-up and survivorship planning
Multidisciplinary Breast Cancer Care
Optimal outcomes in ILC require coordinated care among surgical oncology, medical oncology, radiation oncology, radiology, and pathology teams. Treatment decisions are best made through tumor board discussions to ensure personalized and evidence-based planning.

Recovery and Post-Treatment Care
Recovery after breast cancer surgery depends on the procedure performed. Most patients undergoing breast-conserving surgery return home within 24–48 hours. Mastectomy may require slightly longer hospitalization.
Postoperative care includes wound management, drain care (if applicable), physiotherapy guidance to prevent shoulder stiffness, and lymphedema prevention strategies.
Hormone therapy or chemotherapy is coordinated with medical oncology specialists. Regular follow-up visits ensure early detection of recurrence and management of therapy-related side effects.
Prognosis of Invasive Lobular Carcinoma
When detected early, ILC has excellent long-term survival rates. Hormone receptor positivity often allows effective endocrine therapy, significantly reducing recurrence risk.
Prognosis depends on:
- Tumor size
- Lymph node involvement
- Tumor grade
- Receptor status
- Response to therapy
Long-term follow-up is essential due to the possibility of late recurrence.
