Invasive Ductal Carcinoma (IDC)

At Tucson Breast Health Specialists, we understand that a diagnosis of Invasive Ductal Carcinoma (IDC) can be overwhelming. Our compassionate team, led by Dr. Michele Ley, MD, FACS, is here to guide you through understanding IDC, the treatment options available, and the care plan that best fits your needs and lifestyle.

What is Invasive Ductal Carcinoma?

Invasive Ductal Carcinoma (IDC) is the most common type of breast cancer, accounting for approximately 70–80% of all breast cancer diagnoses. IDC begins in the milk ducts of the breast and then “invades” nearby breast tissue. This is different from ductal carcinoma in situ (DCIS), which remains confined to the ducts and is considered non-invasive.

Risk factors include a family history of breast cancer, certain genetic mutations, prior breast conditions, and lifestyle factors.

Diagnosing IDC

A diagnosis of IDC usually begins with routine screening mammography or a breast exam. If a suspicious area is identified, a biopsy is performed to confirm the presence of invasive cancer. Additional imaging, such as ultrasound or MRI, may be recommended to assess the extent of the disease.

Once confirmed, your care team will evaluate the tumor size, location, lymph node involvement, and hormone receptor status to guide personalized treatment planning. At Tucson Breast Health Specialists, we emphasize shared decision-making, ensuring patients understand their diagnosis and the treatment options available.

Treatment Approaches for IDC

Treatment for IDC is highly individualized, depending on the type and stage of cancer, as well as the patient’s overall health and personal preferences. Dr. Ley and our team focus on minimally invasive techniques and oncoplastic surgery to optimize outcomes while preserving breast appearance whenever possible.

Surgical Options

• Lumpectomy or Partial mastectomy– Also called breast-conserving surgery, removes the cancerous tumor and a margin of surrounding tissue while preserving most of the breast. 
• Mastectomy – Removes the entire breast, sometimes recommended for larger tumors or when multiple areas of the breast are affected.

Adjunct Therapies

• Radiation Therapy – Usually recommended after a lumpectomy to reduce the risk of recurrence. 
• Medical Therapy – This may include chemotherapy, hormone therapy, or targeted therapy, depending on the tumor’s characteristics. 

Our holistic approach ensures that treatment is tailored to each patient’s needs, balancing the effectiveness of cancer control with quality-of-life considerations.
