Treatment for Paget disease of the breast is planned around two things at once: the changes in the nipple itself, and the breast cancer that is very often found in the breast tissue beneath it. Surgery is usually the centerpiece, with radiation and medicine treatments added according to what the underlying cancer turns out to be. This guide explains, in general terms, how doctors build that plan.
Key Takeaways
- Paget disease of the breast is a change in the skin of the nipple caused by cancer cells in the nipple’s skin layer — and in most cases there is also a cancer in the breast tissue underneath, either in situ or invasive.
- Because of that, planning always involves examining and imaging the whole breast, not just treating the nipple as a skin problem.
- Surgery is usually the central treatment. Depending on the extent of disease, that can mean removing the nipple and areola along with the tissue beneath, or a mastectomy.
- Radiation is commonly added after breast-conserving surgery. Medicine treatments — chemotherapy, hormone therapy, targeted therapy — are decided by the features of the underlying cancer, as they are for other breast cancers.
- Every plan is individual. Your team will explain what they found in your case and which parts of treatment they recommend, and why.
What Paget Disease Is, and Why It Shapes the Plan
Paget disease of the breast begins with changes in the skin of the nipple — redness, flaking, crusting, or soreness that does not settle the way ordinary eczema does. The cause is the presence of cancer cells within the skin of the nipple, and in most cases those cells are connected to a cancer in the ducts or tissue of the same breast. Our explainer on Paget disease of the breast covers the signs and how it is diagnosed, and our comparison of Paget disease and nipple eczema explains how doctors tell it apart from a harmless skin condition.
This double nature is why treatment planning looks beyond the nipple. A plan that addressed only the skin would risk leaving the underlying cancer untreated, so the team’s first task is always to establish the full picture: whether an underlying cancer is present, whether it is in situ or invasive, and how much of the breast it involves. The framework they work within is the same one described in our pillar guide on how breast cancer treatment plans are made.
The Information Doctors Use
Before recommending a plan, your team pulls together a standard set of facts:
| Factor | Why it matters |
|---|---|
| Biopsy of the nipple skin | Confirms Paget disease by showing the characteristic cancer cells in the skin layer. |
| Imaging of the whole breast | Mammogram and sometimes other imaging look for the underlying cancer and show how much of the breast is involved. |
| Whether the underlying cancer is in situ or invasive | In situ disease is confined to the ducts; invasive disease has grown beyond them. This changes the scale of the plan. |
| Extent and position of disease | Whether changes are limited to the nipple area or extend widely through the breast influences the surgery that is possible. |
| Receptor and HER2 results | Testing on the cancer tissue shows whether hormone therapy or HER2-targeted medicines could form part of the plan. |
| Lymph nodes | If the underlying cancer is invasive, the nodes under the arm are usually checked to see whether cancer has reached them. |
| Your health and preferences | Other medical conditions and what matters to you — including your feelings about breast conservation and reconstruction — shape the final plan. |
Surgery: The Centerpiece
Surgery is the main treatment for Paget disease, and it has two broad forms. The first is breast-conserving surgery adapted to this condition: the nipple and areola are removed, together with a cone of the tissue beneath them containing the underlying cancer, while the rest of the breast is kept. This is considered when the disease appears limited in extent, and imaging and tissue sampling support that picture. The second form is mastectomy — removal of the whole breast — which is recommended when the underlying cancer is widespread through the breast, appears in more than one area, or cannot be cleared with acceptable margins by a smaller operation.
Which form fits is a judgement your surgical team makes from the imaging, the biopsy results, and what is found as treatment proceeds; it is not decided by the words “Paget disease” alone. If the underlying cancer is invasive, the lymph nodes under the arm are usually sampled during the operation — often by sentinel node biopsy, which checks the first nodes the breast drains to. If mastectomy is chosen, reconstruction can be discussed with the surgical team, either at the same operation or later. Ask your surgeon to explain what your operation would involve and what the breast and nipple area would look like afterwards; that conversation is a normal part of planning, not an afterthought.
Radiation After Surgery
When breast-conserving surgery is used, radiation to the remaining breast tissue is commonly recommended afterwards, to lower the chance of the cancer returning in that breast. This follows the same principle as radiation after a lumpectomy for other breast cancers. After mastectomy, radiation is not always needed; whether it is advised depends on features such as the size and extent of the underlying cancer and whether lymph nodes were involved.
Your team will explain whether radiation fits your situation, what a course of it involves day to day, and how it is sequenced with any other treatments. If radiation is not recommended in your case, that too is a considered decision your team can explain.
Medicine Treatments for the Underlying Cancer
Medicine treatments — treatments that work through the whole body rather than on one area — are not prescribed for the nipple change itself. They are decided by the underlying cancer, using the same reasoning as for any breast cancer found in the same situation. Chemotherapy may be recommended when the underlying cancer is invasive and its features suggest it would add benefit. Hormone therapy is considered when the cancer carries hormone receptors, and HER2-targeted medicines when it is HER2-positive. Our article on how doctors approach DCIS treatment is relevant reading when the underlying cancer turns out to be in situ, because the principles overlap.
Where the underlying cancer is in situ only, medicine treatment is often limited or not needed at all, and the plan may centre on surgery, with or without radiation. Where it is invasive, the plan is usually broader. Your oncologist will set out which medicines, if any, they recommend for you and the reasoning behind it — the answer depends on your pathology results, not on the Paget disease label by itself.
The Order of Treatment
For most people, the sequence begins with the investigations described above, then surgery, then any radiation or medicine treatments that follow from what surgery and pathology show. Occasionally, when an underlying invasive cancer is larger, medicine treatment is given before surgery to shrink it — your team would explain if they think that approach fits your case. Follow-up afterwards includes regular checks of the breast and ongoing screening of the other breast, as with other breast cancers.
It is worth knowing that plans sometimes evolve: what is found at surgery can add detail to the picture, and later recommendations are adjusted to match. That is a normal feature of breast cancer care rather than a sign that anything went wrong, and your team should keep you informed at each step.
Questions to Ask Your Doctor
- Has an underlying cancer been found in my breast, and is it in situ or invasive?
- How much of the breast is involved, according to the imaging?
- Which operation do you recommend for me — breast-conserving surgery or mastectomy — and why?
- Will my lymph nodes be checked, and how?
- Will I need radiation after surgery?
- Do I need any medicine treatments, and what do my receptor and HER2 results mean for that?
- If I have a mastectomy, what are my reconstruction options?
- What follow-up and screening will I have afterwards?
Frequently Asked Questions
Can Paget disease be treated with creams instead of surgery?
The skin changes of Paget disease are caused by cancer cells in the nipple, usually connected to a cancer in the breast beneath — so creams that treat the surface cannot address the cause. Surgery is the main treatment. If a nipple rash has been treated as eczema and is not settling, that is a reason to ask for it to be looked at again and biopsied.
Does Paget disease always mean a mastectomy?
No. Mastectomy is recommended when the underlying disease is widespread or cannot be cleared by a smaller operation, but when the disease is limited, breast-conserving surgery that removes the nipple, areola, and the tissue beneath — usually followed by radiation — can be an option. Your surgical team will explain which applies to you and why.
What if no underlying cancer is found?
Occasionally, careful imaging and sampling find Paget disease without a separate underlying cancer that can be detected. The nipple changes themselves still need treatment, which usually means surgery to remove the affected area, and your team will plan follow-up so the breast continues to be checked. They will explain how your follow-up is arranged.
Will I need chemotherapy for Paget disease?
Chemotherapy is not given for Paget disease as such. It is considered when the underlying cancer is invasive and its features suggest chemotherapy would add benefit — the same decision framework used for other invasive breast cancers. Whether it applies to you depends on your pathology results, which your oncologist will go through with you.
What happens to the nipple in breast-conserving surgery for Paget disease?
Because the disease is in the nipple itself, breast-conserving surgery for this condition removes the nipple and areola along with the tissue beneath them, while keeping the rest of the breast. It is natural to want to know what to expect in appearance and feeling afterwards, and your surgical team can talk that through in detail before you decide anything.
