The short answer
Open surgery uses one larger cut. Minimally invasive surgery uses a few small cuts and a thin tube with a tiny camera. NCI says recovery is faster with minimally invasive surgery. Your surgeon will tell you which approach is right for your cancer.
Open surgery uses one larger incision; minimally invasive surgery uses small cuts and a camera.
NCI says minimally invasive surgery takes less time to recover from than open surgery, because the cuts are smaller.
Not every cancer or situation suits both approaches, so ask your surgeon which one is right for you.
The best approach depends on the cancer, its location, your health, and your surgeon's advice.

The short version
This page is for anyone facing cancer surgery who wants to understand the two main approaches.
Open surgery uses one larger incision (cut). Minimally invasive surgery uses a few small cuts instead of one large one. NCI says that because the cuts are smaller, recovery takes less time than after open surgery. Which approach is right depends on your cancer, where it is, and your health, and your surgeon is the person to ask.
How open surgery works
In open surgery, the surgeon makes one larger cut to reach the area being treated.
How minimally invasive surgery works
In minimally invasive surgery, the surgeon makes a few small cuts. NCI says the surgeon inserts a long, thin tube with a tiny camera, called a laparoscope, into one of the small cuts. Other tools go through the other cuts.
Not every cancer suits both approaches
Smaller cuts are appealing, but a faster recovery is not the only thing to weigh. Whether minimally invasive surgery is an option depends on the type and location of your cancer. Ask your surgeon why they recommend one approach over the other, and whether the operation might need to change to open surgery partway through.
Choosing with your surgeon
The best way to decide is a clear conversation. Questions to ask your surgeon:
- Which approach do you recommend for my cancer, and why?
- What would recovery look like each way?
- How much experience do you have with this approach?
- Is there a chance the surgery would need to become open?
Your surgeon can match the method to your case.
Common questions
What is the difference between open and minimally invasive surgery?
Open surgery uses one larger incision so the surgeon can see and reach the area directly. Minimally invasive surgery uses several small cuts, a camera, and long thin instruments. The choice depends on the cancer, its location, and your overall situation.
Is minimally invasive surgery always better?
Not always. NCI says recovery is faster with minimally invasive surgery, but whether it is a good choice depends on your cancer and your health. Your surgeon can tell you whether it is an option for you.
Does minimally invasive surgery remove cancer as well as open surgery?
That depends on the type of cancer and where it is, and we did not find a federal source that gives one answer for all cancers. Ask your surgeon whether minimally invasive surgery is an appropriate option for your cancer and how it compares with open surgery for you.

Review details and limits
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes, and this is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and then compared with the sources listed on it, looking for statements those sources do not back up. That check is not a sentence-by-sentence record and can miss errors. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
