SABCS 2026 runs December 8–11, 2026 in San Antonio, Texas.
This is a practical guide to the official poster and presentation rules for the San Antonio Breast Cancer Symposium (SABCS) 2026: the poster size and format, the e-poster requirement handled through AbstractsOnline, oral and spotlight slide expectations, where accepted abstracts are published in Clinical Cancer Research, the disclosure and AI-use policies you have to clear, and the breast-oncology figures that make a poster or slide worth stopping for. Several exact specifications — the poster board dimensions, the e-poster file format, whether the abstract itself may contain a figure, and the precise venue hall — are set in the official 2026 SABCS Abstract Guide, so confirm those there before you print or upload. Every date and specification below links to official SABCS materials.

1. SABCS 2026 at a Glance: Dates, Venue & Key Deadlines
SABCS 2026 runs December 8–11, 2026 in San Antonio, Texas (Central Time), and the regular abstract deadline of July 13, 2026 has already closed — acceptance notifications are sent in early September 2026. Late-breaking abstracts are accepted only for genuinely new data that became available after the regular deadline, and every accepted abstract must be presented in person by a co-author listed at the time of submission. Early registration opened July 16, 2026, so if you are a presenting author it is worth mapping the full SABCS 2026 timeline now. SABCS is billed as the largest breast cancer research symposium in the world; the exact host venue building is set on the official SABCS site and 2026 Abstract Guide, so confirm the specific convention-center hall there rather than assuming last year's location.
Here is the SABCS 2026 poster and presentation timeline that matters, drawn from the official SABCS 2026 home and SABCS abstract information. The session-by-session program is posted on the same official site as it is finalized.
| Date | Milestone |
|---|---|
| July 13, 2026 | Regular abstract submission closed (Central Time) |
| July 16, 2026 | Early registration opens |
| After the regular deadline | Late-breaking abstracts accepted for new data only |
| Early September 2026 | Regular abstract acceptance notifications sent |
| September–December 2026 | Poster, slide, and figure preparation window |
| December 8–11, 2026 | SABCS 2026, San Antonio, Texas |
A presentation note: acceptance carries an in-person obligation. Because accepted abstracts must be presented on site by a listed co-author, confirm who will travel and register early rather than after your figures are done.
2. SABCS 2026 Poster Size, Format & Template
The exact SABCS 2026 poster board size, orientation, and layout rules are published in the official 2026 SABCS Abstract Guide — confirm the dimensions there before you design or print, rather than assuming a size from a previous year. As of July 21, 2026 the specific board measurements and orientation are not restated on the public SABCS pages, so the Abstract Guide (and your AbstractsOnline account) is the authoritative source. What does not change year to year is the anatomy of a strong breast-oncology poster: a title header band, the author and affiliation row beneath it, one dominant "hero" figure, and supporting methods, results, and disclosure panels arranged so a delegate grasps the story in seconds.
Whatever the final SABCS 2026 poster size turns out to be, design to these principles from the start:
- Confirm the board dimensions first — pull the poster size and orientation straight from the official 2026 SABCS Abstract Guide and build your canvas to that spec.
- Show your abstract number — it identifies your poster on the boards and in the published record, so place it clearly.
- Lead with one hero figure — a breast-cancer mechanism or trial schema that carries the science, not a dense grid of small panels.
- Readable from a distance — high contrast and clear hierarchy get a poster read in a busy hall.
The breast-oncology figures on a SABCS poster — a drug mechanism of action, an endocrine or CDK4/6 pathway, a randomized trial schema — are the slowest part of that layout to produce. You can generate publication-grade versions online for free and drop them straight into your composition.

SABCS 2026 e-posters are handled through the AbstractsOnline platform, and the exact file format, size limits, and upload deadline are specified in the official 2026 SABCS Abstract Guide and inside your AbstractsOnline account. Because these specifications are set in the Abstract Guide rather than restated publicly, confirm them there before you export — do not assume a format from another meeting. An e-poster is viewed and downloaded on screens rather than read from a meter away, so crisp vector-style figures read far better than photographed or low-resolution images; a mechanism diagram exported cleanly stays legible when a delegate zooms in on a laptop.
The e-poster workflow runs on the official AbstractsOnline meeting platform, where SABCS posts the presenter tools and specifications for accepted abstracts. Treat the e-poster as a first-class deliverable, not an afterthought: the same figures that anchor your printed board should stay sharp on screen.
4. SABCS 2026 Oral & Spotlight Presentations: Slides & Time Limits
If your abstract is selected for a SABCS 2026 oral or spotlight presentation, the exact time limit and slide format arrive with your acceptance materials and are set in the official Abstract Guide — confirm them there rather than assuming a standard 16:9 template. As of July 21, 2026 SABCS has not restated a required slide aspect ratio or template on its public pages, so those specifications come from your acceptance notification and the Abstract Guide. What does not change is the visual demand of a short breast-oncology talk: a spotlight slot gives you time for only a handful of slides, so nearly every SABCS presentation slide needs one clear figure — a mechanism schematic, an endocrine pathway, a trial design — doing the explaining rather than a wall of text.
For a SABCS oral or spotlight presentation, plan your slide figures the same way you plan the poster hero: one idea per slide, one clean figure carrying it. A single well-built mechanism or trial-schema figure reused across your poster, e-poster, and slides keeps the study story consistent and saves hours of duplicated design work.
5. What Figures Do You Need? Poster · Slides · Abstract
Across your poster, your slides, and — where the official Abstract Guide permits it — the abstract itself, a SABCS breast-oncology audience expects the same few figure types, and the most time-consuming ones can be generated online for free in minutes. The exact mix depends on your track (HR-positive endocrine therapy, HER2-directed antibody–drug conjugates, triple-negative breast cancer, CDK4/6 inhibition, and so on), but a handful of jobs recur across the meeting.
On your poster and e-poster, the recurring breast-cancer figure types are:
- Drug mechanism of action (MOA) — for example an antibody–drug conjugate (ADC) binding its target, internalizing, and releasing a cytotoxic payload. The figure that decides whether your poster gets read.
- Endocrine or CDK4/6 pathway — the estrogen-receptor signaling or CDK4/6–cyclin D–Rb axis your study intervenes on, drawn with publication-grade clarity. CDK4/6 inhibitors are well established in HR-positive disease (NCI, cancer.gov · Accessed July 21, 2026).
- Randomized trial schema — a CONSORT-style flow from enrollment and randomization through treatment arms, follow-up, and endpoints, which is central at a practice-changing, RCT-heavy meeting.
- Receptor-status or subtype panel — a clean depiction of HR, HER2, and TNBC status that a reviewer will scrutinize first.
On your slides, an oral or spotlight presenter needs one clean figure per slide — usually the single mechanism or trial-design figure that carries the talk.
In your abstract itself, whether SABCS 2026 permits a figure, table, or image is set in the official 2026 SABCS Abstract Guide — confirm the current rule and any size or resolution limits there before you rely on it. If figures are allowed, a clean mechanism schematic or trial schema in the abstract is a genuine, often overlooked place to make your science legible before a reader ever reaches your poster, because accepted abstracts become part of the citable Clinical Cancer Research record.
Each of these historically takes hours in a vector editor. You can generate them from a text prompt or turn your accepted abstract PDF into a starter figure instead, then refine and export.

A winning SABCS poster passes two tests: a delegate grasps it in three seconds walking past, and it is scientifically exact enough to survive scrutiny from a breast oncologist standing in front of it. The best layouts are built around one dominant hero figure — usually the ADC mechanism or a trial schema with the key result nearby — with everything else arranged to support it. One strong figure beats a dense grid of small panels every time.
The second test is where scientific figures live or die — and where general-purpose AI image generators fall short. A tool like Nano Banana Pro or GPT Image can produce something that looks about 99% right, but on a scientific figure 99% right is effectively 0% right: a single reversed pathway arrow, a mislabeled receptor, or a garbled trial arm turns a compelling poster into one that misleads a reviewer. And a flat, raster AI image gives you no way to fix that last one percent.
This is the core difference with SciFig. Every figure is a fully editable SVG whose elements — arrows, labels, receptors, cells, trial arms — you can correct individually, so you (the author who actually knows the biology) close the gap to 100% and sign off on the science. That author-in-the-loop, element-level editing is also what lets you meet the AACR Journals expectation of author responsibility and disclosure for AI-assisted figures. The breast-oncology figures that reward this care are exactly the ones reviewers scrutinize:
- HER2 / HR / TNBC subtype — keep receptor status straight; confusing HR-positive, HER2-positive, and triple-negative disease, or mislabeling HER2 IHC scoring, is the error a breast oncologist notices first (ASCO guidelines · Accessed July 21, 2026).
- ADC mechanism — get the antibody → linker → payload → internalization → bystander-effect sequence right; a broken linker or payload step misrepresents how the drug works (NCI drugs approved for breast cancer · Accessed July 21, 2026).
- CDK4/6 and endocrine pathways — draw the CDK4/6–cyclin D–Rb axis and ER signaling with arrows pointing the correct way; a reversed pathway arrow inverts the biology.
- Trial schema — get enrollment, randomization, arms, and endpoints in the right order; a mislabeled arm undermines the whole result.
Whether your SABCS 2026 poster earns its attention comes down to whether these figures are accurate, clear, and legible — which is exactly where an editable AI figure workflow compresses days of design work into hours without giving up scientific control.
7. Create Your SABCS 2026 Figures with AI: The SciFig Workflow
You already have two things most colleagues do not: your accepted abstract and a clear understanding of your study's mechanism — use both to generate your figures online for free, then edit them to exactly right. Here is the SciFig workflow for a SABCS presenter:
Path 1 — Upload your accepted abstract PDF. Drop it into PDF-to-Figure. It parses your Background, Methods, and Results and returns a starter mechanism diagram or trial schema in one click — you begin refining from a 70%-there draft, not a blank canvas.
Path 2 — Copy a structured prompt. For a mechanism or pathway figure, Text-to-Figure gives more control. Copy and adjust to your study:
Schematic of an antibody-drug conjugate mechanism in HER2-positive breast
cancer: the antibody binds HER2 on the tumor cell, the complex is
internalized, the linker is cleaved to release the cytotoxic payload,
inducing tumor-cell death and a bystander effect on neighboring cells.
Path 3 — Sketch and scan. If you sketched your hero figure on paper, photograph it and drop it into Sketch-to-Figure to get a publication-style version that preserves your topology. If you are starting from an existing low-resolution figure, Figure Enhancer rebuilds it as a clean editable version.
From any path, you edit individual elements in the vector canvas — adjust labels, colors, receptor placement, trial arms — and export to editable PPTX or layered SVG for final composition, at high resolution for print without artifacting. A new SciFig account starts with 150 starter credits plus 50 refill credits every day, which covers a full set of poster figures for most authors. For the companion guides in this conference series, see the SITC 2026 poster guide, the AHA Scientific Sessions 2026 poster guide, and the ESMO 2026 poster guide.
Optional — disclose your AI use. AACR's editorial policy expects authors to disclose AI assistance and remain responsible for accuracy. If you build and review a figure in SciFig, you can note it in the caption — for example: Figure created by the authors using SciFig and reviewed for scientific accuracy (scifig.ai).

Use the path that matches what you already have, then edit every element until the breast-cancer science is exact.
Try Free8. SABCS 2026 Presenter Policies: Disclosure, Embargo & AI Use
Every SABCS 2026 presenter must complete a conflict-of-interest (COI) disclosure and confirm the prior-publication status of the work, and AI use in abstracts and manuscripts follows the AACR Journals editorial policy — author responsibility plus disclosure, not a prohibition. Handle these steps early, because disclosure belongs on the poster and slides themselves, and confirming that your data are not previously published is part of the submission record. There is no official SABCS poster or slide logo rule, so the space other meetings spend on branding is better spent making your figures accurate and legible.
On AI specifically, the AACR editorial approach is that authors remain responsible for the accuracy and integrity of anything AI-assisted and must disclose its use — which is exactly why an editable, author-reviewed figure workflow matters. Because SciFig figures are editable SVGs you verify element by element, you can honestly attest that a human author checked the science, and you can state the tool used. For the current, authoritative wording, confirm the disclosure and AI policies on the official SABCS abstract information and the Clinical Cancer Research / AACR journal pages before you submit.
Tip
The single highest-leverage decision in your preparation window is which figure becomes the hero. Pick the one your delegates need to remember 24 hours later — usually the ADC mechanism or a trial schema with the key result nearby — and design the rest of the poster around it.
9. Where SABCS 2026 Abstracts Are Published (Clinical Cancer Research)
Accepted SABCS 2026 abstracts are published in the online Proceedings and as an online-only supplement in Clinical Cancer Research — an American Association for Cancer Research (AACR) journal — alongside the SABCS Sessions and Poster Resources posted online. This makes your abstract, and any figure the Abstract Guide allows in it, part of a permanent, citable record. Searches for "SABCS 2026 abstracts" or the SABCS abstract supplement almost always mean this Clinical Cancer Research supplement.
Because your abstract becomes part of this citable AACR record, it is worth making sure the figure in your abstract, on your poster, and on your slides all tell the same study story. Once the supplement is live, use it to confirm the citable version of your SABCS abstract, then keep every figure consistent across formats. You can see the format in a prior-year example of the Clinical Cancer Research SABCS supplement.
