Finding Your Balance After Breast Cancer Surgery: Understanding and Embracing Breast Asymmetry

Breast asymmetry is something many women live with, but after breast cancer surgery, it can become an especially sensitive part of the healing journey. Whether you've had a lumpectomy, mastectomy, or reconstruction, your relationship with your body may feel very different post-treatment. And while surgical outcomes can be transformative, they aren't always symmetrical—and that’s completely normal.
Types of Breast Cancer Surgeries and Their Impact on Breast Asymmetry
Every breast cancer journey is deeply personal, and so are the treatments and surgeries that come with it. Some women undergo:
Lumpectomy (Breast-Conserving Surgery): Where only the tumour and a small area of tissue are removed. This can leave one breast smaller or differently shaped than the other.
Therapeutic Mammoplasty: A breast-conserving surgery technique used to remove breast cancer while simultaneously reshaping the breast, which often results in a smaller and more uplifted breast
Mastectomy: The removal of one or both breasts. For those who choose not to have reconstruction, this can result in more visible asymmetry.
Reconstruction Surgery: Using implants, fat transfer, DIEP flap, or tissue from another part of the body to recreate the breast. While reconstruction aims for balance, it isn’t always perfect.
How Radiation, Hormones, and Weight Fluctuations Can Cause Breast Imbalance Over Time
Even if your initial surgery or reconstruction left your breasts looking symmetrical, changes can still occur over time. Radiation therapy can cause tissue to shrink or harden, making one breast appear smaller or higher. Hormonal changes, weight fluctuations, and ageing can also lead to noticeable shifts, especially if your cancer treatment was pre-menopause. Each breast might respond differently to these changes, particularly if only one side received radiation. As a result, asymmetry might not show up immediately but can develop months or even years later.
This can be an emotional challenge—especially after everything you've already overcome. The trauma that can come with breast cancer treatment is profound, and by the time you've healed physically, you might wish for a solution that doesn't remind you of hospitals, appointments, or cancer itself. Choosing a non-surgical, non-medical solution can be a powerful way to restore balance to your bra and move forward, free from the clinical trappings of your treatment journey.
From Lightweight Foam to Lasting Balance: Choosing the Right Breast Form
During the early stages of recovery, it's common to start with a lightweight foam breast form (sometimes called a comfie or softie). These are ideal while your scars and skin are still healing, offering comfort without pressure. However, because they lack the weight to stay in place and balance chest weight effectively, many women find that moving to a silicone insert which offers a more secure, natural-feeling solution once your doctor confirms it's safe to do so.
Non-Surgical Solutions for Uneven Breasts After Cancer Treatment
At Evenly, we believe restoring your sense of balance shouldn't come with clinical fittings or post-surgical bras. Our products are designed for women who want practical, stylish solutions to uneven breasts—whether you're post-surgery or simply have natural asymmetry.
Bra Balancers: Silicone Inserts for Breast Asymmetry
Our Bra Balancers are perfect if your asymmetry is more pronounced (either 1-2 cup sizes difference, or to 2-3 cup sizes). They're soft, silicone inserts that blend invisibly into your everyday bras, giving a natural, balanced look without needing a nurse’s appointment or specialised bra. If you're using a Bra Balancer post-mastectomy on a flat chest wall, it provides a realistic B or C cup projection. The concave back allows water to flow through, making it an excellent choice as a swim form too.

Subtle Shapers: Smoothing Inserts for Breast Imbalance
For smaller differences (up to 1 cup size), our Subtle Shapers offer gentle, lightweight correction. They slip into your bra to smooth over scar tissue or indentations (especially common after lumpectomy) and to balance a slight difference in fullness - ideal for everyday wear when you want to feel just right.
These aren’t medical devices—they’re wearable confidence. They’re for every woman, every day. And they come with no stigma, no extra appointments, and no high price tag.
