Certified lymphedema therapy for breast cancer survivors at every stage — from early swelling to established lymphedema — at Thera Physical & Occupational Therapy in Midtown Manhattan.
Book a Free Consultation Learn About the RegionsWhat Is Breast Cancer–Related Lymphedema?
Breast cancer treatment — including surgical removal of axillary lymph nodes and radiation to regional lymph node fields — can compromise the lymphatic drainage network of the arm, breast, and trunk. When lymphatic vessels are disrupted or removed, fluid that would normally flow through those pathways can accumulate in the surrounding tissue, causing swelling, heaviness, and discomfort.
This is breast cancer–related lymphedema. Unlike acute post-surgical swelling, which resolves as healing progresses, lymphedema is a chronic condition rooted in structural changes to the lymphatic system. It can develop weeks, months, or even years after treatment, and its severity ranges from subtle changes in limb volume to significant, persistent swelling that affects daily function.
Lymphedema is not inevitable, and it is manageable. Certified lymphedema therapy — when started early and maintained over time — is the most effective approach available to reduce swelling, prevent progression, and preserve quality of life.
No referral required. New York State allows direct access to physical and occupational therapy for up to 10 visits or 30 days without a physician referral. You do not need to wait for a script to begin lymphedema care at Thera.
The Three Regions We Treat
Breast cancer–related lymphedema does not always present in the arm. Depending on the surgical approach, extent of lymph node removal, and radiation field, swelling can occur in distinct anatomical regions — each requiring an individualized treatment approach.
Arm & Hand Lymphedema
The most recognized presentation. Swelling develops in the arm, forearm, and hand on the side of surgery due to disrupted axillary drainage. May be accompanied by heaviness, aching, and reduced grip.
Breast & Chest Wall Lymphedema
Swelling in the remaining breast, chest wall, or reconstructed breast tissue following mastectomy or lumpectomy with radiation. Often presents as fullness, firmness, or visible asymmetry.
Truncal Lymphedema
Fluid accumulation in the lateral trunk, back, or axillary region. Often underrecognized, truncal lymphedema may present as soft, puffy tissue along the side of the body or under the arm.
Arm & Hand Lymphedema After Breast Cancer
Arm lymphedema is the most studied and widely recognized form. It most commonly follows axillary lymph node dissection (ALND), where a larger number of lymph nodes are removed, but can also occur after sentinel lymph node biopsy (SLNB) — particularly when combined with axillary radiation. The affected arm may feel heavy, tight, or numb. Rings or clothing sleeves may feel constricting. Early stages may involve only subtle, intermittent fullness; established lymphedema produces more persistent and visible changes.
Breast & Chest Wall Lymphedema
Following lumpectomy with whole breast radiation, or mastectomy with post-mastectomy radiation therapy (PMRT), the breast tissue, chest wall, or reconstruction site can develop localized lymphedema. This may appear as visible swelling or a firm, boggy texture in the breast — particularly in the outer quadrant near the axilla — or across the chest wall after mastectomy. Breast lymphedema is frequently underreported because it can be mistaken for normal post-surgical or post-radiation changes. A qualified therapist can differentiate between tissue types and assess whether lymphatic involvement is present.
Truncal Lymphedema
The lateral trunk — the tissue along the side of the torso, below the axilla and toward the back — is part of the same lymphatic drainage territory as the arm. When axillary lymph nodes are compromised, this region can accumulate fluid independently of, or alongside, arm swelling. Truncal lymphedema often goes undiagnosed because it does not produce visible limb swelling. Patients may describe a soft, pillowy area under the arm or along the side of the chest that does not resolve with time. Manual lymphatic drainage and targeted compression strategies can redirect fluid toward functioning lymph node basins.
Who Is at Risk, and When to Seek Care
Not every breast cancer survivor will develop lymphedema. Risk is shaped by the type and extent of surgery, radiation, individual anatomy, and other factors. Understanding your risk allows for proactive monitoring and earlier intervention when symptoms do appear.
- Axillary lymph node dissection (ALND) — the single strongest surgical risk factor, with an estimated 20% lifetime risk of arm lymphedema
- Sentinel lymph node biopsy (SLNB) — lower risk than ALND (~5–7%), but not negligible, particularly when combined with axillary radiation
- Radiation to axillary, supraclavicular, or internal mammary nodes — increases risk independently and compounds surgical risk
- Post-mastectomy radiation therapy (PMRT) — associated with both arm and chest wall / truncal lymphedema
- Infection (cellulitis) in the at-risk limb — can trigger or worsen lymphedema and should be treated promptly
- BMI and body composition changes — adipose tissue deposition can exacerbate lymphatic compromise
- Delayed or untreated acute post-surgical swelling — early swelling that persists is worth evaluating, not watching
Lymphedema can develop years after treatment. Many patients first notice symptoms 12–18 months post-surgery, or later. If you have a history of breast cancer surgery or radiation and are experiencing new swelling, heaviness, or changes in tissue texture, a lymphedema evaluation is appropriate regardless of how long ago your treatment concluded.
Our Approach to Lymphedema Care
Our certified lymphedema therapists use Complete Decongestive Therapy (CDT) — the internationally recognized, multi-component standard of care — individualized to your presentation, region(s) of involvement, and overall treatment goals.
Comprehensive Lymphedema Evaluation
We begin with a full assessment: limb and trunk volume measurements, skin and tissue assessment, palpation of the affected region(s), range of motion testing, and a detailed review of your surgical, radiation, and medical history. We stage your lymphedema using the International Society of Lymphology (ISL) classification and establish an individualized baseline for monitoring.
Manual Lymphatic Drainage (MLD)
MLD is a specialized, gentle technique that uses light, rhythmic strokes mapped to the superficial lymphatic pathways to redirect fluid away from congested areas toward functioning lymph nodes. For breast and truncal lymphedema, drainage is re-routed through alternate pathways — an approach that requires detailed anatomical knowledge and CLT-level training. MLD is performed only by our certified therapists; it is not the same as standard massage.
Compression Therapy
Compression is a cornerstone of lymphedema management, but the approach differs by region. For the arm and hand, this typically involves compression sleeves and gauntlets, with multi-layer bandaging during intensive treatment phases. For breast and truncal lymphedema, specialized foam padding, chip bags, and custom garments are used. We take precise measurements, recommend appropriate products, and provide clear instruction on wear schedules and care.
Therapeutic Exercise
Targeted movement supports lymphatic flow and is safe — and beneficial — for breast cancer survivors with lymphedema. We guide you through our Strength After Breast Cancer (ABC) Program, a supervised rehabilitative protocol that incorporates progressive resistance training shown in research to support lymphatic function and overall recovery without increasing lymphedema risk.
Skin Care & Infection Prevention
Lymphedematous tissue is significantly more vulnerable to infection. Cellulitis in an affected arm or breast region can be serious and can worsen lymphedema. We provide individualized education on skin hygiene, moisturization, wound care, and the early signs of cellulitis that warrant prompt medical attention.
Self-Management Education & Home Program
Long-term lymphedema control depends substantially on what you do outside of clinic appointments. We teach self-bandaging techniques (where appropriate), home drainage exercises, garment care, and strategies for managing flare-ups. We also provide up-to-date guidance on activity precautions — many older restrictions have been revised based on current evidence — and clarify which recommendations apply to your specific clinical picture.
Our certified lymphedema therapists are here to create a personalized care plan for your region(s) of involvement, your surgical history, and your goals.

Lymphedema After Breast Cancer — FAQ
I had a sentinel node biopsy, not a full dissection. Can I still develop lymphedema?
Yes. Sentinel lymph node biopsy carries an estimated 5–7% risk of arm lymphedema compared to approximately 20% with axillary lymph node dissection. If you also received radiation to the axillary region, your risk may be somewhat higher. A consultation with a certified lymphedema therapist can establish your baseline and clarify a monitoring plan appropriate to your surgery.
My arm swelling started two years after my mastectomy. Is it too late for therapy?
No. Lymphedema can develop at any point after treatment and benefit from therapy at any stage. Earlier intervention is generally associated with better long-term outcomes, but established lymphedema — even years in — can be meaningfully improved with appropriate CDT. We see many patients who are years out from treatment and are experiencing new or worsening symptoms.
What is truncal lymphedema and how is it different from arm swelling?
Truncal lymphedema refers to fluid accumulation in the lateral trunk — the soft tissue along the side of the torso, under the axilla, and toward the back — rather than in the arm itself. It occurs in the same drainage territory as arm lymphedema but does not always co-occur with arm swelling. It can present as soft, puffy tissue along the side of the body that does not resolve with time. A specialized assessment is needed to identify it, and treatment involves adapted MLD pathways and truncal compression strategies.
Is lymphedema curable?
Lymphedema is a chronic condition and is not currently curable, as it reflects structural changes to the lymphatic system. However, it is very manageable. Many patients achieve significant, long-term control of symptoms through consistent therapy, appropriate compression, exercise, and self-care. The goal of treatment is to reduce swelling to its lowest stable level and maintain that over time.
Does insurance cover lymphedema treatment?
Many insurance plans, including Medicare, cover lymphedema therapy when medically necessary. Coverage for compression garments varies by plan. New York State has legislation supporting some garment coverage. We recommend contacting your insurer directly; our team can provide documentation to support your claim.
Can I exercise if I have lymphedema in my arm or breast?
Yes. Current research strongly supports exercise — including progressive resistance training — for people with breast cancer–related lymphedema. Exercise does not increase lymphedema risk when performed appropriately. We guide every patient through a structured, individualized exercise program as part of their lymphedema care plan.
