Acupuncture on the arm after lymph node removalYou can have acupuncture after lymph node removal; the open question is whether needles go in that arm. The advice differs, the trial data is small and calm.
Axillary web syndrome (cording) after breast surgeryCording is a tight cord under the arm that appears 2 to 8 weeks after breast or node surgery. It is common, not a clot or recurrence; therapy helps.
Baseline arm measurements before breast cancer surgeryBoth arms measured before surgery makes early lymphedema detectable: a 3% change means nothing without a baseline. Why, how often after, and who does it.
Blood pressure and needles on the affected armThe NLN now says a cuff, injection or blood draw on an at-risk arm has not been linked to swelling and may be done, your choice. A swollen arm is different.
Body weight and lymphedema risk after breast cancerA BMI of 30 or more before surgery, and swings of about 10 lb a month afterwards, raise lymphedema risk. What studies found, what they did not.
Cellulitis risk with lymphedema after cancerRed, hot, painful skin on an at-risk or swollen limb is a same-day medical problem: cellulitis damages lymphatics and is the best-known lymphedema trigger.
Compression sleeve to prevent lymphedema after breast cancerA preventive sleeve after axillary dissection reduced and delayed arm swelling in a 307-woman trial: 42% vs 52% at one year. Who it is for.
Does chemotherapy raise lymphedema risk?Pre-surgery chemotherapy is a risk factor in several cohorts and taxanes cause fluid retention, but a matched study of 1,494 women found no taxane effect.
Does massage spread cancer?No research has shown that massage spreads cancer, and it does not treat cancer either. Why trained therapists still adapt pressure and site, and when to ask.
Early signs of arm lymphedema after breast cancerA tight ring or watch, a heavy or full arm and a sense it is bigger come before measurable swelling and predict lymphedema. What counts, and who to tell.
Flying after lymph node removalProspective studies have not linked flying to lymphedema after node removal, and the NLN no longer routinely advises a sleeve for flights. Who still should.
Head and neck lymphedema after cancer treatmentThree in four people have some lymphedema after head and neck cancer treatment, and most of it is inside the throat. Why swallowing and voice changes matter.
Immediate lymphatic reconstruction and lymphedema riskImmediate lymphatic reconstruction (LYMPHA) cut lymphedema after node dissection from about 21% to 8% in pooled studies. Why screening continues.
Leg lymphedema after gynecologic cancer treatmentLeg lymphedema follows cervical, endometrial, ovarian and vulvar cancer treatment in up to half of cases. The drivers, the early peak, and how CDT works.
Lymphedema after an axillary lymph node dissectionAfter an axillary dissection about one in four women develops arm lymphedema within five years, one in three with radiation. Sleeve and measuring evidence.
Lymphedema after groin dissection for melanomaGroin dissection carries the highest lymphedema risk of any melanoma node surgery: 24% in the MSLT-II trial vs 6% with observation. Signs, care, red flags.
Lymphedema after prostate cancer treatmentLeg or genital lymphedema after prostate cancer is uncommon after surgery alone and far more likely when pelvic radiation follows a node dissection.
Lymphedema risk after a sentinel node biopsyA sentinel node biopsy carries a small lymphedema risk, about 5.6% pooled and 5 to 17% in ACS figures, versus 20 to 30% after dissection.
Lymphedema risk after regional node radiationRegional node radiation is an independent lymphedema risk factor that stacks with dissection (31.2% at five years) and pushes onset later, to 18 to 48 months.
Lymphedema screening: bioimpedance vs tape measureA tape measure tracks limb volume (5 to 10% thresholds); bioimpedance reads extracellular fluid (L-Dex). What the PREVENT trial found.
Massage during chemotherapy: what changesMassage during chemotherapy is possible with your team's agreement. When to book in the cycle, and how counts, ports and skin change a session.
Massage during radiation therapy: skin and timingMassage can continue during radiotherapy if treated skin is left alone: no pressure, oil, heat or friction over the field, shorter sessions led by fatigue.
Massage for chemotherapy-induced neuropathyNo drug prevents chemotherapy neuropathy and only duloxetine has guideline support for the pain. Small massage trials show relief; here is what they found.
Massage for chemotherapy-related fatigueMassage is a recognized option for cancer-related fatigue: one trial showed relief, a Cochrane review calls the evidence weak. What a session looks like.
Oncology massage: pressure, positioning and safetyOncology massage is an approach, not a technique: an intake, then adjustments to pressure, site, position, duration and heat. What each one changes, and why.
Radiation fibrosis after cancer treatmentRadiation fibrosis is slow scarring in treated tissue that can appear months or years later. Not reversible, but stiffness and pain are manageable.
Reducing lymphedema risk after breast cancerAbout one in five women develops arm lymphedema after breast cancer. The 2026 NLN evidence ranks screening, skin care, weight, exercise and a sleeve first.
Scar care after cancer surgeryScars from cancer surgery keep changing for up to two years, so there is time. When to start massage, how irradiated skin and drains change the rules.
Weight lifting and lymphedema: what the PAL trial foundIn the PAL trial, slow, supervised weight lifting in a compression garment did not increase arm swelling and halved flare-ups. The design that made it safe.
When does lymphedema start after cancer treatment?Most lymphedema starts within two to three years of treatment, earlier after a dissection and later after node radiation. Why the risk never fully closes.
