What to expect from immunotherapy for triple-negative breast cancer

Triple-negative breast cancer does not use the usual hormone or HER2 pathways for treatment decisions. Immunotherapy works through the immune system and may be included with chemotherapy or another part of a treatment plan when your cancer features, stage, and overall health make it appropriate. Your team will explain whether the aim is to treat cancer before surgery, after surgery, or when it has spread.

An infusion visit can involve a symptom check, examination, blood tests, medicine through a vein, and observation. Possible effects include tiredness, nausea, rash, diarrhoea, cough, joint aches, or changes in appetite. Immune inflammation can also affect the thyroid, adrenal glands, liver, lungs, bowel, kidneys, or nerves, sometimes after a delay.

Before each infusion, mention changes in your breast or surgical area, fever, bowel habits, breathing, skin, energy, mood, or menstrual and other hormone-related symptoms. Bring a complete medicine list and tell the team about autoimmune conditions, pregnancy plans, or breastfeeding.

Plan rest and practical help around visits, especially if treatment is combined with chemotherapy or surgery. Keep blood tests, scans, and follow-up appointments. Write down symptoms with their start date and severity; this helps the team distinguish treatment effects from infection, surgery recovery, or other causes.

Contact your oncology team promptly for persistent diarrhoea, repeated vomiting, yellowing of the eyes, dark urine, a spreading rash, new cough, breathlessness, severe headache, confusion, dizziness, unusual thirst, or a substantial change in urination. Report fever or signs of infection around a wound as well.

Seek emergency care for severe breathing difficulty, fainting, sudden confusion, swelling of the face or throat, or new one-sided weakness. A symptom does not need to be severe before you mention it to the cancer team.

Ask why immunotherapy is recommended in your situation, how it fits with chemotherapy and surgery, which tests guide treatment, and how side effects could affect the schedule. Ask about fertility, contraception, breastfeeding, and who to contact outside clinic hours.
