The short answer
For oropharyngeal cancer, surgery or radiation first is the central decision, and NCI treats it as open. In pooled data on base of tongue cancer, survival was close either way, while severe complications were 32 percent with surgery and 3.8 percent with radiation.
This page draws on NCI's adult oropharyngeal cancer summary; other head and neck sites are staged and treated differently.
In historical, nonrandomized data on 6,400 people with base of tongue cancer, 5-year survival was 49 percent with surgery and 52 percent with radiation, a difference that was not significant.
Severe complications in that analysis were 32 percent with surgery and 3.8 percent with radiation, and fatal ones 3.5 percent against 0.4 percent.
For tumors of the oropharynx the p16 stain shows whether HPV is involved, and NCI lists trials that use it to lower the radiation dose.

The full explanation.
What this page covers, and what it does not
"Head and neck cancer" is a family, not one disease. Oral cavity, larynx, hypopharynx, nasopharynx, salivary gland, sinonasal and oropharyngeal tumors differ in how they are staged, whether HPV matters, and which operations and drug treatments apply. The evidence quoted below is drawn from NCI's PDQ summary on adult oropharyngeal squamous-cell cancer. Use it as a model for the kind of question to ask; check the answers against the summary for your own primary site before treating any figure here as yours. If nobody has told you the exact site and cell type yet, that is the first question.
Surgery first, or radiation first
For oropharyngeal tumors this is the central decision, and NCI treats it as genuinely open. For early stage disease it says one treatment alone is preferred, and that radiation alone was historically the usual choice.
Transoral surgery, including robotic surgery, is being used more. NCI says comparisons that were not randomized suggest better quality of life with these smaller operations than with the older, bigger ones.
The numbers behind that choice
NCI pools 6,400 people with cancer at the base of the tongue, treated between 1970 and 2000. This is historical, nonrandomized data: people were not assigned to surgery or radiation by chance, so sicker or healthier patients may have been steered to one arm. Five-year survival was 49 percent with surgery and 52 percent with radiation, a difference that was not significant.
The difference was in harm. Severe complications occurred in 32 percent of the surgery group and 3.8 percent of the radiation group. Fatal complications occurred in 3.5 percent and 0.4 percent.
For tonsil cancers in the same analysis, severe complications were 23 percent with surgery and 6 percent with radiation. Survival again looked similar.
Those figures come from an older era of surgery, and the comparison was never randomized. That is exactly why it is fair to ask how your own surgeon's results compare today.
HPV status and lower-dose trials
For tumors of the oropharynx, the p16 stain tells you whether HPV is involved. NCI lists two kinds of trial that use that result: lowering the radiation dose, and using transoral surgery followed by a lower radiation dose.
Both are marked as under study. Ask whether one is open to you, and what joining would mean.
Radiation that spares the salivary glands
NCI reports on a trial of intensity-modulated radiation. Moderate or worse dry mouth affected 55 percent at six months, 25 percent at one year and 16 percent at two years.
Ask whether your plan spares the parotid glands, and whether it keeps dose off the muscles you swallow with.
Dental work before radiation starts
Radiation to this area affects the jawbone. In that same trial, jawbone breakdown occurred in 6 percent of people.
Ask for a dental assessment before treatment begins, and ask how much healing time is needed before the first session.
The neck, and whether it needs an operation
NCI describes a trial of 564 people with advanced neck nodes. One group had a planned neck dissection. The other was watched with PET-CT scans and operated on only if needed.
Far fewer operations were done in the scan group, 54 against 221. Two-year survival was 84.9 percent with scan-guided watching and 81.5 percent with planned neck dissection. The trial met its bar for noninferiority, and the death rate slightly favoured the scan-guided group.
Ask whether that approach applies to you.
Questions for the visit
- Is surgery or radiation the better first step for my tumor?
- What are your own complication rates for this operation?
- Is my tumor p16 positive?
- Is there a lower-dose trial I could join?
- Will my radiation spare my salivary glands?
- Can my dental work be done before radiation starts?
- Do I need a neck dissection, or can scans guide that?

Common questions
Is surgery or radiation the better first step?
NCI treats this as genuinely open and prefers one treatment alone for early stage disease. Survival looked similar in the pooled analysis; the complication rates did not. Ask your surgeon for their own figures.
Why does my p16 result matter?
It shows whether HPV is involved in an oropharyngeal tumor. NCI lists two kinds of trial that use it: lowering the radiation dose, and transoral surgery followed by a lower dose. Both are marked as under study.
Do I need dental work before radiation starts?
Ask for a dental assessment before treatment begins. Radiation to this area affects the jawbone, and breakdown occurred in 6 percent in the trial NCI reports. Ask how much healing time is needed first.
Can I avoid an operation on my neck?
Sometimes. In the trial NCI describes, scan-guided watching led to far fewer operations and met the bar for noninferiority. Ask whether that approach applies to you.

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.
