What you need to know about Invasive ductal carcinoma (IDC)

Invasive ductal carcinoma (IDC) is the most common type of breast cancer, accounting for about 80% of all breast cancer diagnoses. It begins in the milk ducts and invades the surrounding breast tissue.

Invasive ductal carcinoma (IDC) is the most common type of breast cancer, accounting for about 80% of all breast cancer diagnoses. It begins in the milk ducts and invades the surrounding breast tissue.

The term “invasive” indicates that the cancer has spread beyond the ducts into nearby breast tissue, and potentially to other parts of the body.

Invasive Ductal Carcinoma (IDC) can be classified into several subtypes based on certain histological and molecular characteristics

  1. Classic Invasive Ductal Carcinoma (No Special Type)

    • Description: Most common form, standard abnormal ductal cells invading breast tissue.

  2. Tubular Carcinoma

    • Description: Forms tube-shaped structures.
    • Prognosis: Good, usually hormone receptor-positive.

  3. Mucinous (Colloid) Carcinoma

    • Description: Cells produce mucus around them.
    • Prognosis: Favorable, often hormone receptor-positive.

  4. Medullary Carcinoma

    • Description: Large, high-grade cells with clear tumor boundaries.
    • Prognosis: Good despite aggressive appearance, often triple-negative.

  5. Papillary Carcinoma

    • Description: Forms finger-like projections.
    • Prognosis: Good, often hormone receptor-positive.

  6. Cribriform Carcinoma

    • Description: Nest-like structures with holes.
    • Prognosis: Favorable, often hormone receptor-positive.

  7. Metaplastic Carcinoma

    • Description: Contains non-glandular tissue elements like bone or cartilage.
    • Prognosis: More aggressive, often triple-negative.

  8. Micropapillary Carcinoma

    • Description: Small, tight clusters of cells.
    • Prognosis: Higher lymph node involvement, variable hormone receptor status.

  9. Adenoid Cystic Carcinoma

    • Description: Contains both glandular and cystic features.
    • Prognosis: Good, rare subtype.

These subtypes help determine the treatment approach and prognosis. Diagnosis involves imaging, biopsy, and histological examination.

  • Genetic Factors:
    • Family history of breast cancer, genetic mutations such as BRCA1 and BRCA2.
  • Hormonal Factors:
    • Prolonged exposure to estrogen, such as early menstruation, late menopause, or hormone replacement therapy.
  • Lifestyle Factors:
    • Obesity, alcohol consumption, and lack of physical activity.
  • Age:
    • Risk increases with age, particularly after age 50.
  • Reproductive History:
    • Never having been pregnant or having the first pregnancy after age 30.
  • Lump in the Breast:
    • A hard or irregularly shaped lump that can be felt in the breast or underarm.
  • Changes in Breast Shape or Size:
    • Unexplained changes in the size, shape, or appearance of the breast.
  • Nipple Changes:
    • Inversion, discharge (possibly bloody), or changes in the appearance of the nipple.
  • Skin Changes:
    • Dimpling, puckering, redness, or thickening of the skin on the breast.
  • Pain:
    • Persistent pain in the breast or nipple, although not common, can occur.
  • Physical Examination:
    • Doctor performs a breast exam to check for lumps or other changes.
  • Imaging Tests:
    • Mammogram: X-ray of the breast to detect abnormalities.
    • Ultrasound: Uses sound waves to produce images of structures within the breast.
    • MRI: Provides detailed images using magnetic fields and radio waves.
  • Biopsy:
    • Fine-Needle Aspiration (FNA): Removes a small sample of tissue with a thin needle.
    • Core Needle Biopsy: Uses a larger needle to remove a core of tissue.
    • Surgical Biopsy: Removes a larger section or lump for examination.
  • Pathology Report:
    • Analysis of biopsy samples to determine cancer type, grade, and hormone receptor status (ER, PR, HER2).
  • Surgery:
    • Lumpectomy: Removal of the tumor and a small margin of surrounding tissue.
    • Mastectomy: Removal of the entire breast, sometimes including nearby lymph nodes.
  • Radiation Therapy:
    • High-energy rays to destroy remaining cancer cells post-surgery.
  • Chemotherapy:
    • Drugs to kill cancer cells, often used before surgery (neoadjuvant) or after surgery (adjuvant).
  • Hormone Therapy:
    • For hormone receptor-positive cancers, drugs like tamoxifen or aromatase inhibitors to block estrogen.
  • Targeted Therapy:
    • Drugs targeting specific proteins on cancer cells, such as HER2 inhibitors (trastuzumab).
  • Immunotherapy:
    • Boosts the body’s immune system to fight cancer cells.
