Large Breast Implants (600cc+): What to Know Before Going Big: Considering 600cc, 800cc, or 1000cc+ breast implants? See what large implants look like, medical limits, long-term risks, and why staged augmentation may be safer.
Key Takeaways
- Most manufacturers define "large" implants as 600cc and above. The largest standard stock implants are typically 800–850cc.
- Custom implants above 850cc exist but require special ordering and carry significantly greater risk.
- Large implants place more stress on breast tissue, skin, and the musculoskeletal system — increasing long-term complication rates.
- Staged augmentation (two procedures over 6–12 months) is often recommended when going very large on a small frame.
- Board-certified plastic surgeons may decline to perform very large augmentations they deem unsafe for a patient's anatomy.
What Counts as a "Large" Breast Implant?
There is no universal cutoff, but most surgeons and manufacturers treat 600cc and above as the large-implant threshold. Here is a rough size framework:
Approximate breast implant size classification.
| Volume Range | Classification | Typical Use |
|---|---|---|
| Under 300cc | Small to moderate | Subtle enhancement, natural look |
| 300–450cc | Moderate to large | Most common augmentation range |
| 450–600cc | Large | Significant enhancement; requires adequate tissue |
| 600–800cc | Very large | Dramatic results; careful patient selection required |
| 800–850cc | Extra large (standard stock) | Upper limit for most manufacturers' catalogues |
| 850cc+ | Custom / ultra-large | Special order; substantially elevated risk profile |
What 600–800cc Actually Looks Like
Volume numbers are often misleading without anatomical context. A 700cc implant on a 5'4" 130 lb patient with a 12 cm breast base width looks dramatically different from 700cc on a 5'9" 175 lb patient with a 15 cm base.
At 600–800cc on an average frame, patients typically achieve a DD to G+ cup result, depending on starting size, profile, and placement. The look is full and projected — undeniably "augmented" rather than natural. At these sizes, implants are visible in profile even under clothing.

Beyond 800cc: Custom Orders & Tissue Expanders
Standard manufacturer catalogues (Allergan, Mentor, Sientra, Motiva) typically top out around 800–850cc for round silicone implants. Above this range, options are limited:
- Custom-ordered implants: Some manufacturers can produce implants above catalogue sizes on a custom basis. Lead times and costs are significantly higher.
- Tissue expanders: A staged approach where an expander is placed first and gradually inflated over weeks to stretch the skin envelope before the final large implant is placed.
- Multiple augmentation stages: Starting with a moderately large implant, then exchanging for a larger device after the tissue has accommodated — sometimes called "staged augmentation."
- Realistic ceiling: Even with custom implants, surgeons assess the chest anatomy for structural limits. Rib cage shape, skin thickness, and shoulder width all impose practical limits.
Medical Limits — Why Surgeons Refuse Certain Sizes
Board-certified plastic surgeons are ethically and medically permitted to decline performing augmentations they consider unsafe. This is not arbitrary — it is tissue-based planning in practice. Surgeons may refuse very large sizes because:
- Tissue coverage inadequacy: Thin patients with minimal breast tissue may have insufficient coverage over a very large implant, leading to visible edges, rippling, or implant show-through.
- Skin stretch limits: Skin that is stretched beyond its capacity to recoil will bottom out, develop striae (stretch marks), or allow the implant to migrate inferiorly.
- Structural load: Very large implants in petite patients can cause chronic neck, shoulder, and back pain.
- Long-term revision burden: Larger implants have statistically higher reoperation rates, earlier failure, and more complex revision scenarios.
If a board-certified plastic surgeon declines to perform a requested size, that is clinical judgment — not a second-best outcome. Seeking a less experienced provider willing to perform the procedure carries significantly elevated risk.
Long-Term Risks of Large Implants
All implants carry baseline risks, but large implants increase several of them:
- Tissue thinning: Large implants stretch and thin the overlying breast tissue over years, making future revision more difficult.
- Bottoming out: The implant migrates downward as the inferior pole skin stretches — more common with heavier devices.
- Back and postural strain: Extra weight on the chest alters posture and can cause chronic musculoskeletal issues.
- Higher revision likelihood: FDA post-approval studies show reoperation rates increase with implant size. Very large implants often require more complex and costly revisions.
- Implant palpability: Large implants in thin patients are often palpable and visible through skin.
- Capsular contracture: Some evidence suggests larger devices may have modestly higher capsular contracture rates, though this is confounded by patient selection.
Staged Augmentation
Staged augmentation is the process of reaching a very large final size in two operations rather than one. The first procedure places a moderately large implant (or tissue expander) to begin stretching the skin and tissue. After 6–12 months of healing, the second procedure exchanges for the desired larger device.
This approach reduces complication risk, improves final aesthetics, and gives the body time to adapt to increased implant weight. It adds cost but meaningfully improves safety for patients seeking very large results on smaller frames.
