Top Surgery vs. Mastectomy: Understanding the Difference

By Dr. Tina Jenq | Oregon Cosmetic and Reconstructive Clinic | Serving Portland & Happy Valley

As a plastic surgeon at Oregon Cosmetic and Reconstructive Clinic in Happy Valley, I often meet patients who want clear, honest information about gender-affirming top surgery—especially how it compares to a mastectomy performed for cancer treatment or prevention.

Although these procedures may sound similar, they have very different goals, techniques, and outcomes. Let me walk you through this in a simple, supportive way.

At our clinic in Happy Valley, we are proud to serve patients seeking top surgery from Portland, Clackamas, and throughout the Pacific Northwest.

Top Surgery vs. Mastectomy: What’s the Difference?

Cancer-Related Mastectomy

Goal: Remove as much breast tissue as possible

When surgeons perform a mastectomy for cancer treatment or prevention, the priority is medical safety. The goal is to remove as much breast tissue as possible to reduce cancer risk or treat disease.

Because of that focus:

• The chest is often flat

• Contour shaping is not the main priority

• Aesthetic sculpting is secondary to cancer control

---

Gender-Affirming Top Surgery

Goal: Create a natural, affirming chest contour

Top surgery has a very different purpose. My focus is to create a chest shape that aligns with your gender identity while maintaining harmony with your natural anatomy.

Instead of removing every bit of tissue, I often leave a carefully controlled amount of tissue in specific areas to:

• Create a natural slope

• Add pectoral definition

• Avoid hollowing or irregularities

• Support smooth skin redraping

This is where surgical precision and artistry truly matter.

How I Tailor Tissue Contouring

Every chest is unique. I customize surgery based on several important factors:

Rib Cage Shape

A rounder rib cage may need slightly more tissue to maintain smooth contour.
A flatter chest wall often allows more direct sculpting.

Desired Aesthetic

Some patients prefer:

• A more defined pectoral look

• A softer, flat appearance

Your goals guide how I thin and shape the remaining tissue.

Skin Quality & Elasticity

Skin plays a major role in choosing the safest and most effective technique. I carefully assess:

• How much extra skin is present

• Whether skin can shrink and re-drape smoothly

• Natural fold lines

• Whether the nipple-areola complex can stay in place or needs repositioning

These details help me select the approach that produces the most predictable, balanced result.

Surgical Techniques I Use

Double Incision Technique

This is the most common approach for patients with more tissue or excess skin.

It allows me to:

• Remove excess skin

• Resize or reposition the nipple-areola complex

• Sculpt the chest with precision

This method creates strong, reliable contouring and typically reduces the need for later revision.

---

Lower Elliptical Incision Technique

For patients with moderate tissue and good skin elasticity, this technique allows me to:

• Maintain a higher natural areolar position

• Create a clean, flat contour

• Use a shorter scar pattern

It works beautifully when the skin can re-drape smoothly.

---

Keyhole Technique

This approach works best for patients with:

• Small breast volume

• Tight, elastic skin

• Minimal excess tissue

Through a small incision—often around the areola—I remove tissue and shape the chest while preserving nipple position and avoiding large scars.

Frequently Asked Questions

Is top surgery a mastectomy?

Technically, yes—because breast tissue is removed. However, top surgery is a reconstructive, gender-affirming procedure focused on contour and alignment. A cancer mastectomy focuses on total tissue removal for medical reasons.

Does top surgery prevent breast cancer?

Top surgery removes most tissue, but it is not a total mastectomy. A small amount of tissue often remains to create a natural chest slope. During consultation, we discuss your individual cancer risk and screening plan.

How is top surgery different from a double mastectomy?

A double mastectomy usually refers to cancer-related removal of both breasts. Top surgery uses specialized contouring techniques—such as Double Incision, Lower Elliptical, or Keyhole—to create a natural-looking masculine or nonbinary chest.

Why This Surgery Feels So Meaningful

I feel deeply honored to perform gender-affirming top surgery.

Many patients tell me that surgery removes the daily mental load of binding, hiding their chest, or feeling uncomfortable in public. Afterward, they often describe a sense of:

• Freedom

• Comfort

• Alignment between identity and appearance

Helping someone move through the world with more ease—and less emotional weight—is one of the most gratifying parts of my practice.
