Breast Carcinoma
Breast carcinoma is a term that often arises in medical discussions, yet its distinction from general breast cancer is frequently misunderstood. Medicover hospitals aims to elucidate the complexities surrounding breast carcinoma, including its symptoms, causes, diagnosis, and treatment options.
What is Breast Carcinoma?
Breast carcinoma is a type of cancer that begins in the epithelial cells lining the ducts or lobules of the breast. Unlike benign tumors, carcinomas have the potential to invade surrounding tissues and metastasize to distant parts of the body. The term "carcinoma" specifically refers to cancers that originate in epithelial cells, distinguishing it from other types of breast cancer that might arise from different cell types.
Breast Carcinoma vs. Breast Cancer
While the terms "breast carcinoma" and "breast cancer" are often used interchangeably, it is important to note that "breast cancer" is a broader term that encompasses all malignant tumors in the breast. Carcinoma is the most common form of breast cancer, but other types exist, such as sarcomas and lymphomas, which originate from different tissues within the breast.

Understanding the etiology of breast carcinoma is crucial for both prevention and treatment. While the exact cause remains unknown, several factors have been identified as contributing to the risk of developing the disease.
Genetic Predispositions
Approximately 5-10% of breast carcinoma cases are attributed to hereditary factors. Mutations in the BRCA1 and BRCA2 genes significantly increase the risk of developing breast carcinoma. These genetic alterations can be inherited from either parent and are prevalent among certain populations.
Hormonal Influences
The role of hormones in breast carcinoma development is well-documented. Estrogen and progesterone, in particular, can promote the growth of breast cancer cells. Prolonged exposure to these hormones, such as through hormone replacement therapy or early menstruation combined with late menopause, can elevate risk levels.
Environmental and Lifestyle Factors
Factors such as diet, physical activity, and alcohol consumption also play a role in breast carcinoma risk. Obesity, especially post-menopause, has been linked to increased risk due to elevated estrogen levels produced by adipose tissue. Additionally, exposure to radiation and certain environmental pollutants can contribute to the development of breast carcinoma.
Symptoms of Breast Carcinoma
Early detection of breast carcinoma is pivotal for successful treatment outcomes. Therefore, awareness of its symptoms is essential.
Common Symptoms
- Lump or Mass: The presence of a new lump or mass in the breast is the most common symptom. These lumps are often hard, irregular in shape, and painless, but they can also be soft or tender.
- Swelling: Swelling of all or part of the breast, even without a distinct lump, can be indicative of carcinoma.
- Nipple Changes: Symptoms may include nipple retraction, discharge (other than breast milk), or thickening of the skin around the nipple area.
- Skin Irritation or Dimpling: The texture of the breast skin may change, resembling an orange peel.
Less Common Symptoms
- Pain: While most breast lumps are painless, some individuals experience pain or tenderness.
- Lymph Node Swelling: Swelling or lumps in the lymph nodes under the arm or around the collarbone can be a sign of breast carcinoma.
Diagnosing Breast Carcinoma
Timely and accurate diagnosis is crucial in the management of breast carcinoma. Several diagnostic methods are employed to confirm the presence of cancerous cells.
Imaging Tests
Mammography is the most common imaging test used for breast carcinoma screening. It can detect tumors that are too small to be felt. Other imaging modalities, such as ultrasound and magnetic resonance imaging (MRI), may be used to further evaluate suspicious areas.
Biopsy Procedures
A biopsy involves the removal of breast tissue for examination under a microscope. It is the definitive method for diagnosing breast carcinoma. There are various types of biopsies, including fine-needle aspiration, core needle biopsy, and surgical biopsy, each with its own indications and advantages.
Treatment Options for Breast Carcinoma
The treatment of breast carcinoma is multifaceted and depends on several factors, including the stage of cancer, its hormonal receptor status, and the patient's overall health.
Surgical Interventions
Surgery is often the first line of treatment for breast carcinoma. The primary types of surgical procedures include:
- Lumpectomy: Also known as breast-conserving surgery, this involves removing the tumor and a small margin of surrounding tissue while preserving most of the breast.
- Mastectomy: This entails the removal of the entire breast and is recommended in cases where lumpectomy is not feasible.
- Lymph Node Surgery: Sentinel lymph node biopsy or axillary lymph node dissection may be performed to assess the spread of cancer.

Following surgery, additional treatments may be administered to reduce the risk of recurrence:
- Radiation Therapy: This uses high-energy rays to destroy remaining cancer cells in the breast or surrounding tissues.
- Chemotherapy: Systemic treatment with drugs that target and kill cancer cells throughout the body.
- Hormonal Therapy: For hormone receptor-positive breast carcinoma, medications that block or lower estrogen levels can be effective.
- Targeted Therapy: Drugs that specifically target cancer cell mechanisms, such as HER2 inhibitors, may be used in certain subtypes of breast carcinoma.
