The short answer
Small surface penile cancers can be treated with Mohs surgery, fluorouracil or imiquimod cream, laser or cryosurgery. The hard part is the groin nodes, where NCI says hidden spread is common but whether preventive dissection improves survival is not known.
For cancer that has not grown deep, NCI says treatment advice rests largely on case reports and small series rather than trials.
The surface options NCI lists are Mohs surgery, fluorouracil cream, imiquimod 5 percent cream, Nd:YAG or carbon dioxide laser, and cryosurgery, several with good cosmetic results.
For cancer limited to the foreskin, wide local excision with circumcision may be enough. For tumors growing into the head of the penis, NCI treats amputation, radiation including brachytherapy, and microscopically controlled surgery as equivalent.
Groin node surgery carries infection, skin death, wound breakdown, long-term swelling and a low but real risk of death, and NCI says whether preventive dissection improves survival is not known.

The full explanation.
Small surface cancers have gentle options
Penile cancer is uncommon. The American Cancer Society's 2026 projection is 2,260 new cases and 450 deaths in the United States. NCI's PDQ summary still carries the 2025 figures, 2,190 new cases and 510 deaths, so the two do not match.
For cancer that has not grown deep, NCI says treatment advice rests largely on case reports and small series rather than trials. It is worth knowing that before you weigh the options.
The options it lists are real, though. Mohs surgery, which removes thin layers and checks each one under the microscope. Fluorouracil cream, effective in the surface conditions called erythroplasia of Queyrat and Bowen disease. Imiquimod 5 percent cream, which NCI says has worked with good appearance and function. Laser treatment with Nd:YAG or carbon dioxide, with excellent cosmetic results. Cryosurgery, also with good cosmetic results.
Ask which of these fits your tumor, and what the chance of it returning is for each.
Taking less, and keeping more
For cancer limited to the foreskin, NCI says wide local excision with circumcision may be enough.
For tumors growing into the head of the penis, the choice is set by size, depth and how much normal tissue is destroyed. NCI treats three options as equivalent: amputation, radiation including brachytherapy, and microscopically controlled surgery.
Laser treatment with Nd:YAG is listed here too, with control and cure while preserving appearance and sexual function. NCI marks it as under study.
Ask which of these your surgeon does often. Ask how much length you would keep.
The groin nodes are the hard part
Cancer here spreads to lymph nodes in the groin, often before anything can be felt. NCI says this hidden spread is common enough that groin dissection is often done alongside amputation for poorly differentiated tumors.
Then it is honest about the cost. Lymph node surgery carries infection, skin death, wound breakdown, long-term swelling, and a low but real risk of death.
It adds a hard sentence. Whether preventive node dissection improves survival is not known, and opinions on its use differ.
A smaller way to check the nodes
Sentinel node biopsy samples the first node or two rather than clearing the whole groin. NCI describes it being used in T2 disease where the nodes feel normal.
It also reports a single-centre study of 22 people with a false negative rate of 11 percent. Ask how your centre handles that risk.
Questions before surgery is booked
- Is my cancer limited to the foreskin?
- Could cream, laser or Mohs surgery be enough?
- What is the chance of it coming back after each option?
- How much length would each operation leave?
- Do my groin nodes need checking even though they feel normal?
- Would that be a sentinel biopsy or a full dissection?
- What are the wound and swelling risks for me?

Common questions
Could I avoid surgery for a shallow tumor?
Possibly. NCI lists creams, laser, Mohs surgery and cryosurgery for cancer that has not grown deep. Ask which fits your tumor, and what the chance of it returning is for each.
Do my groin nodes need checking if they feel normal?
Often yes. This cancer reaches groin nodes before anything can be felt, which is why NCI says dissection is often done alongside amputation for poorly differentiated tumors. Ask whether a sentinel biopsy could answer the question first.
How much length would I keep?
That depends on the tumor size, its depth and how much normal tissue it has destroyed. Ask each surgeon what margin they need and how much length the operation would leave.

How this page was created
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. We do not employ clinicians and do not intend to — our work 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 checked line by line against the sources listed on it. That confirms the sources support what the page says. 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.
