Can Manual Lymphatic Drainage Help Breast Swelling After Breast Cancer Treatment?

Breast cancer treatment does not always end when surgery or radiation is completed. Some survivors continue to experience swelling, heaviness, tenderness, tightness or discomfort in the treated breast.

A preliminary randomized clinical trial published in May 2026 examined whether adding manual lymphatic drainage, also called MLD, to a broader rehabilitation program could help people experiencing breast edema after breast-conserving surgery and radiation therapy.

The results were encouraging: participants who received MLD in addition to education, compression and exercise reported greater improvements in breast pain, edema-related symptoms and several areas of quality of life than participants who received the same program without MLD.

However, this was a small preliminary study. It does not prove that lymphatic drainage massage will produce the same results for every breast cancer survivor, nor does it show that MLD should replace medical evaluation, compression, exercise or other forms of rehabilitation.

Here is what the researchers studied, what they found and what the results may mean for people seeking manual lymphatic drainage in Austin after breast cancer treatment.

What Is Breast Edema?

Breast edema is swelling caused by an accumulation of fluid within the tissues of the breast. It may develop following breast-conserving surgery, commonly called a lumpectomy, particularly when surgery is followed by radiation therapy.

Unlike the arm swelling that many people associate with breast cancer-related lymphedema, breast edema occurs primarily within the treated breast.

Symptoms may include:

• A feeling of heaviness or fullness

• Breast tenderness or pain

• Visible swelling

• Skin tightness or thickening

• Changes in breast texture

• Bra discomfort

• A feeling that one breast is larger, firmer or heavier

• Discomfort with movement or daily activities

  
  

Not every change after surgery or radiation is caused by breast edema. New, worsening or unexplained swelling should first be discussed with the appropriate oncology provider. Redness, heat, fever, drainage, sudden enlargement or increasing pain may require prompt medical evaluation.

What Is Manual Lymphatic Drainage?

Manual lymphatic drainage is a specialized form of gentle, rhythmic hands-on therapy. It is designed to support the movement of fluid through appropriate lymphatic pathways.

MLD is different from traditional Swedish massage, deep-tissue massage and the faster, more pressure-based techniques sometimes marketed as Brazilian lymphatic massage. Proper manual lymph drainage uses light pressure because many lymphatic vessels are located close to the surface of the body.

The National Cancer Institute describes manual lymphatic drainage as a gentle massage technique used to help reduce swelling. It is currently being studied in the United States as supportive care for people receiving radiation after breast-conserving surgery.

When working with someone who has undergone breast cancer treatment, lymphatic techniques must be individualized. The therapist should consider the person’s surgery, lymph-node procedures, radiation field, healing status, current symptoms, medical restrictions and established drainage pathways.

What Did the 2026 Study Examine?

The study, conducted by researchers in Türkiye, included 25 women who had undergone breast-conserving surgery followed by radiation therapy and were experiencing clinically relevant breast edema.

Participants were divided into two groups:

The MLD group received:

• Education

• Compression

• Exercise therapy

• Manual lymphatic drainage

  
  

The comparison group received:

• Education

• Compression

• Exercise therapy

• No manual lymphatic drainage

  
  

Researchers evaluated the participants after radiation therapy and again three months later.

They examined several outcomes, including:

• Breast pain

• General body pain

• Breast edema symptoms

• Fatigue

• Anxiety and depression

• Breast and arm symptoms

• Overall quality of life

  
  

This study focused specifically on breast edema after breast-conserving surgery and radiation—not general wellness-related bloating, routine post-surgical swelling or every form of breast cancer-related lymphedema.

What Did the Researchers Find?

Both groups improved during the three-month study period.

Participants in both groups experienced improvements in areas such as breast edema, breast pain, fatigue, emotional well-being and certain quality-of-life measurements. This is important because both groups received active supportive care, and some natural recovery was also expected during the months following radiation.

However, the group that also received manual lymphatic drainage demonstrated greater improvements in several areas.

Compared with the group that did not receive MLD, the MLD group had additional improvements in:

• Breast pain

• Breast edema-related symptoms

• Clinical breast-related criteria

• Overall health status

• Fatigue

• Pain-related quality of life

• Breast symptoms

• Arm symptoms

• Certain treatment-related side effects

  
  

The researchers concluded that adding MLD to a comprehensive conservative program may provide additional benefits for breast edema following breast-conserving surgery and radiation.

Does This Mean MLD Alone Reduced the Swelling?

Not necessarily.

The participants who received manual lymphatic drainage also received education, compression and exercise. The study therefore evaluated MLD as one part of a larger rehabilitation program, rather than as a stand-alone treatment.

The study also did not include a group that received no care at all. Because both groups were receiving active support during a period when natural healing was expected, the researchers could not completely isolate how much improvement was caused by MLD itself.

This distinction matters when interpreting massage research.

The study supports the possibility that manual lymphatic drainage offers additional benefits when appropriately incorporated into a broader care plan. It does not support claims that MLD can independently cure breast edema or replace compression, therapeutic exercise, physical therapy, medical treatment or lymphedema management.

Important Limitations of the Study

Although this was a randomized controlled trial, the authors described it as preliminary.

Several limitations should be considered:

The study was small

Only 25 participants completed the study: 12 in the MLD group and 13 in the comparison group. Findings from such a small group may not reflect what will happen in a larger or more diverse population.

Some participants did not complete the study

The researchers initially enrolled more participants, but the final sample decreased to 25. The reported attrition rate was approximately 30%.

Many outcomes were self-reported

Participants completed questionnaires about pain, swelling symptoms, fatigue and quality of life. These experiences are meaningful, but future research would be stronger if it also included more objective measurements of tissue fluid and breast volume.

Participants and therapists were not blinded

Participants knew whether they were receiving hands-on treatment, and the clinicians providing MLD also knew which intervention they were performing. This can influence reported outcomes.

MLD was not tested by itself

Because MLD was combined with education, exercise and compression, the exact independent effect of manual lymphatic drainage remains uncertain.

The authors called for larger, well-designed randomized studies using objective measurements and stronger blinding procedures.

Why This Research Still Matters

Breast edema receives less public attention than arm lymphedema, even though breast swelling and pain can meaningfully affect comfort, clothing choices, sleep, body image and daily life after treatment.

This study is valuable because it focused specifically on swelling within the breast following breast-conserving surgery and radiation. It also evaluated more than physical measurements. Researchers considered pain, fatigue, arm and breast symptoms, treatment side effects and quality of life.

The findings suggest that the potential value of MLD may extend beyond a visible change in swelling. For some people, meaningful improvement may involve:

• Less heaviness or tightness

• Reduced breast discomfort

• Greater ease with movement

• Improved comfort in clothing or a bra

• Better tolerance of the affected area

• Improved daily quality of life

  
  

These outcomes still require additional research, but they reflect concerns frequently experienced by people recovering from cancer treatment.

Interest in this subject is continuing in the United States. The National Cancer Institute currently lists an active phase II trial at the USC Norris Comprehensive Cancer Center evaluating breast MLD during and after radiation therapy. Researchers plan to examine feasibility, tolerability, breast edema, pain, function, quality of life, body image and radiation-induced fibrosis. This trial is ongoing, so it should not yet be interpreted as evidence of effectiveness.

Is Lymphatic Drainage Massage Appropriate After Breast Cancer?

Manual lymphatic drainage may be appropriate for some breast cancer survivors, but it is not automatically appropriate for everyone.

Before scheduling lymphatic massage after breast cancer treatment, it is important to consider:

• Whether surgery sites are fully healed

• Whether radiation reactions are still active

• Whether there is an infection or suspected infection

• Whether unexplained swelling has been medically evaluated

• Whether lymph nodes were removed or irradiated

• Whether the person has a history of blood clots

• Whether there are cardiac, kidney or vascular concerns

• Whether the oncology team has issued precautions

• Whether the massage therapist has relevant lymphatic and oncology training

  
  

MLD should not be used to delay evaluation of a new symptom. A massage therapist also should not diagnose breast edema, lymphedema, infection, seroma, fibrosis or cancer recurrence.

Manual Lymphatic Drainage in South Austin

At Evolved Massage & Lymphatics, manual lymphatic drainage sessions are gentle, individualized and adapted to each client’s health history, surgical history and current stage of recovery.

Our South Austin practice works with clients seeking supportive lymphatic care following a variety of medical experiences, including appropriate clients recovering from cancer-related procedures. We do not perform incisional drainage, diagnose medical conditions or replace care from an oncologist, surgeon, physical therapist or certified lymphedema therapist.

For clients with a cancer history, coordination with the medical team may be recommended before beginning massage. The goal is to provide thoughtful, appropriately paced support while respecting the person’s established treatment plan and medical precautions.

The Bottom Line

This 2026 preliminary randomized trial found that people receiving manual lymphatic drainage as part of a broader program experienced greater improvement in breast pain, breast edema-related symptoms and several quality-of-life measures than those receiving the same program without MLD.

The study does not prove that MLD works for everyone or that massage should be used alone. Its small sample size, reliance on subjective measurements and lack of a no-treatment group mean the findings should be interpreted cautiously.

Still, the research adds to growing interest in manual lymphatic drainage as a potential component of supportive rehabilitation following breast-conserving surgery and radiation.

For breast cancer survivors, the most appropriate approach is individualized, medically informed and collaborative. New or worsening swelling should be evaluated first. When manual lymphatic drainage is appropriate, it may be incorporated alongside—not instead of—medical care, exercise, compression and other rehabilitation strategies.
