What happens during chemotherapy?

Medcasts editorial team

Chemotherapy is delivered in cycles — typically every 1–4 weeks. Each cycle includes: pre-treatment labs, IV access (peripheral or port), drug administration over 1–8 hours, pre-medications (antiemetics, steroids, sometimes antihistamines), post-treatment monitoring.

Side effects vary by regimen. Common: fatigue, nausea (well-controlled with modern antiemetics), hair loss with some agents, blood count drops 7–10 days after each cycle.

A full course typically runs 4–8 cycles, though some regimens are open-ended (continued until disease progression). Total treatment time often 4–6 months for adjuvant settings; longer for metastatic.

For international travel, plan around the cycle schedule, not vice versa. Most patients fly home between cycles 2 and 3, with subsequent cycles given by home oncologist.

Methodology and editorial standards

Answers are written by the Medcasts editorial team and updated when prices, guidelines or visa rules change.

  1. Hospital data. Hospital details are compiled from public sources and hospital websites. Accreditation (JCI, NABH and others) is shown where we hold a record of it. Always ask the hospital for its current certificate.
  2. Doctor credentials. Qualifications, specialty and bio come from the doctor's hospital profile. Licence is checked against the national medical-council register only where the profile shows a "Licence verified" badge with a date.
  3. Prices. Price ranges are indicative, compiled from hospital price lists and packages and shown with the date last updated. The hospital's written quote is what you pay against.
  4. Clinical text. Written by the Medcasts editorial team from published clinical sources. Unless a named reviewer is shown on the page, it has not been reviewed by a doctor.
  5. Independence. Hospitals cannot pay to change their position on our pages.
