A mastectomy is a surgical procedure involving the removal of breast tissue, typically performed as a treatment or preventative measure for breast cancer. Removing this tissue requires an incision, which naturally results in a scar as the body heals. Understanding the physical appearance of these scars is important, as their look is influenced by the surgical technique and the body’s individual healing characteristics. The final appearance of a mastectomy scar can vary significantly in shape, length, color, and texture.
The Core Visuals: Appearance and Location
The most recognizable mastectomy scar, associated with a traditional or simple mastectomy, appears as a linear mark across the chest. This scar is usually positioned horizontally or slightly diagonally across the area where the breast mound was located. Initially, the scar appears raised, firm, and often a bright red or purple color due to increased blood flow.
Over time, this color fades as the inflammatory response subsides and the scar matures. The texture also changes, gradually becoming flatter and more supple. The resulting long-term scar is typically a pale white or silver line, though it may be slightly wider than the original incision. If lymph nodes were removed during the surgery, a separate scar may be present in the armpit area.
Scar Variations Based on Surgical Technique
The precise shape and length of the scar are determined by the specific type of mastectomy performed. A total or simple mastectomy, which removes the entire breast, nipple, and areola, generally leaves the longest, most prominent scar. This incision is often elliptical, spanning the width of the chest wall.
A skin-sparing mastectomy (SSM) preserves most of the breast skin envelope for immediate reconstruction. The surgeon removes the tissue through a smaller incision, often placed around the areola or in an existing crease. This approach results in a less extensive, medium-sized scar compared to the total mastectomy.
The nipple-sparing mastectomy (NSM) aims to preserve the nipple and areola, minimizing the visible mark. The incision is strategically placed in an inconspicuous area, such as the inframammary fold or along the edge of the areola. This technique results in a minimal, easily hidden scar, maintaining a more natural contour after reconstruction.
Factors Influencing Scar Healing and Final Look
While the surgeon’s technique dictates the scar’s geometry, several biological factors influence how the scar ultimately matures. Genetics play a significant role in scar formation, with some individuals being predisposed to forming hypertrophic scars or keloids. These appear as scars that are thicker, raised, and more extensive than the original wound site. Skin tone can also affect the final appearance of the scar, particularly concerning pigmentation changes. People with darker skin tones have a greater risk of developing hyperpigmentation, where the scar tissue becomes darker than the surrounding skin. Conversely, people with lighter skin may develop scars that are permanently red or pink. Post-operative complications, such as an infection at the surgical site, can delay healing and lead to a more noticeable, irregular scar. Radiation therapy can also impact the tissue quality, potentially causing the skin to become firmer, thicker, or changing the color of the scar tissue.
Scar Maturation and Long-Term Changes
A mastectomy scar is not static; it undergoes a predictable process of maturation that can take a significant amount of time. The initial phase is inflammatory, lasting several weeks, where the scar is red, swollen, and tender as the body begins to close the wound. The proliferative phase follows, where the body rapidly produces collagen to reinforce the healing area, causing the scar to thicken and darken. The final and longest stage is the remodeling phase, during which the collagen fibers reorganize and strengthen. This process can continue for 12 to 18 months, or sometimes longer, as the scar gradually softens, flattens, and fades to its final color. The scar will become less prominent and easier to manage over time.
