Tail of Spence: A Comprehensive Guide to Breast Anatomy and Health

The “tail of Spence” is a term that, while perhaps unfamiliar to many, refers to a crucial anatomical feature of the human breast. This article aims to provide a comprehensive understanding of the tail of Spence, its significance in breast health, and its relevance in the context of breast cancer detection and treatment. We’ll explore its anatomy, common issues that can arise, and the importance of regular self-exams and clinical screenings. This is your complete guide to understanding this important part of your body.

What is the Tail of Spence? A Deep Dive into Breast Anatomy

The tail of Spence, also known as the axillary tail, is an extension of the breast tissue that extends into the armpit (axilla). It’s essentially a bridge of breast tissue connecting the main body of the breast to the axillary lymph nodes. Understanding its structure is crucial for both self-examination and clinical breast exams.

Anatomical Structure and Composition

The tail of Spence is composed of the same tissues as the rest of the breast, including:

* **Glandular Tissue:** Lobules (milk-producing glands) and ducts (tubes that carry milk to the nipple).
* **Fibrous Tissue:** Provides support and structure to the breast.
* **Fatty Tissue:** Fills the spaces between the glandular and fibrous tissue and contributes to breast size and shape.
* **Blood Vessels and Nerves:** Supply the breast tissue with nutrients and sensation.

It’s important to note that the amount of fatty tissue varies greatly from person to person, influencing the size and prominence of the tail of Spence.

Location and Relationship to the Axilla

The tail of Spence originates from the upper outer quadrant of the breast and extends upwards and outwards towards the armpit. Its proximity to the axillary lymph nodes is particularly significant because these nodes are often the first site of metastasis (spread) for breast cancer. Therefore, any changes or abnormalities in the tail of Spence should be promptly evaluated by a healthcare professional.

Variations in Size and Prominence

The size and prominence of the tail of Spence can vary considerably among individuals. Some women may have a very noticeable tail of Spence, while others may have a less defined extension of breast tissue into the armpit. These variations are normal and are influenced by factors such as genetics, hormonal changes, and body weight. However, any sudden or significant changes in the size or shape of the tail of Spence should be investigated.

The Role of Mammography in Tail of Spence Imaging

Mammography is a crucial tool for detecting breast cancer, especially in the tail of Spence. Because this area extends into the armpit, it’s essential that mammograms capture this region effectively. The positioning during a mammogram is critical to ensure adequate visualization of the tail of Spence. The technologist will carefully position the breast to include as much tissue as possible, including the axillary tail. Sometimes, additional views may be necessary to fully evaluate this area.

Common Issues and Conditions Affecting the Tail of Spence

Several conditions can affect the tail of Spence, some benign and others malignant. It’s important to be aware of these potential issues and to seek medical attention if you notice any concerning changes.

Breast Pain (Mastalgia)

Breast pain is a common complaint, and it can sometimes be localized to the tail of Spence. Hormonal fluctuations, fibrocystic changes, and even muscle strain can contribute to breast pain. While most breast pain is benign, persistent or severe pain should be evaluated by a doctor.

Fibrocystic Changes

Fibrocystic changes are benign conditions that can cause lumpiness, thickening, and tenderness in the breast tissue, including the tail of Spence. These changes are often related to hormonal fluctuations and are more common in women of reproductive age. While fibrocystic changes are not cancerous, they can sometimes make it more difficult to detect cancerous lumps.

Lipomas

Lipomas are benign fatty tumors that can occur in any part of the body, including the breast. They are typically soft, mobile, and painless. Lipomas in the tail of Spence are usually harmless, but they should be evaluated to rule out other potential causes of a lump.

Breast Cancer

Breast cancer can develop in any part of the breast, including the tail of Spence. Because of its proximity to the axillary lymph nodes, cancer in this area can sometimes spread more quickly. Therefore, early detection and treatment are crucial. Any new lump, thickening, or change in the tail of Spence should be promptly evaluated by a healthcare professional.

Self-Examination of the Tail of Spence: A Step-by-Step Guide

Regular self-examination is an important part of breast health awareness. It allows you to become familiar with the normal texture and appearance of your breasts, making it easier to detect any changes that may warrant medical attention. The tail of Spence should be included in your self-examination routine.

When to Perform Self-Exams

The best time to perform a breast self-exam is a few days after your menstrual period, when your breasts are less likely to be tender or swollen. If you are no longer menstruating, choose a specific day of the month to perform your self-exam.

How to Perform a Self-Exam

1. **Visual Inspection:** Stand in front of a mirror and visually inspect your breasts for any changes in size, shape, or appearance. Look for any dimpling, puckering, or redness of the skin. Also, check your nipples for any discharge or inversion.
2. **Palpation While Standing:** Raise one arm above your head and use the pads of your fingers on your other hand to feel for any lumps or thickenings in your breast. Use a circular motion, covering the entire breast area, including the tail of Spence. Pay particular attention to the area near your armpit.
3. **Palpation While Lying Down:** Lie down with a pillow under your shoulder and repeat the palpation process. This position allows the breast tissue to spread out, making it easier to feel for any abnormalities.

What to Look For

* **New Lumps or Thickenings:** Any new lump or thickening in the breast, especially if it feels different from the surrounding tissue.
* **Changes in Size or Shape:** Any noticeable change in the size or shape of your breast.
* **Skin Changes:** Dimpling, puckering, redness, or scaling of the skin.
* **Nipple Changes:** Nipple inversion, discharge, or scaling.
* **Pain or Tenderness:** Persistent or severe breast pain that is not related to your menstrual cycle.

Clinical Breast Exams and the Tail of Spence

In addition to self-exams, regular clinical breast exams performed by a healthcare professional are an important part of breast cancer screening. During a clinical breast exam, your doctor will visually inspect and palpate your breasts, including the tail of Spence, to check for any abnormalities. They will also examine your lymph nodes in the armpit and neck.

Tail of Spence and Breast Cancer Detection

The tail of Spence is a common site for breast cancer development. Several factors contribute to this:

* **Tissue Density:** The tail of Spence often contains a higher concentration of glandular tissue, which is more susceptible to cancer development.
* **Proximity to Lymph Nodes:** The tail of Spence is located near the axillary lymph nodes, which are often the first site of metastasis for breast cancer.
* **Detection Challenges:** Lumps in the tail of Spence can sometimes be more difficult to detect during self-exams or clinical exams due to its location in the armpit.

Treatment Options for Breast Cancer in the Tail of Spence

The treatment for breast cancer in the tail of Spence is similar to the treatment for breast cancer in other parts of the breast. Treatment options may include:

* **Surgery:** Lumpectomy (removal of the tumor and surrounding tissue) or mastectomy (removal of the entire breast).
* **Radiation Therapy:** Uses high-energy rays to kill cancer cells.
* **Chemotherapy:** Uses drugs to kill cancer cells throughout the body.
* **Hormone Therapy:** Blocks the effects of hormones on cancer cells.
* **Targeted Therapy:** Uses drugs that target specific molecules involved in cancer cell growth and survival.

The specific treatment plan will depend on the stage and type of cancer, as well as the patient’s overall health and preferences.
