Chemotherapy

Drug treatment that reaches cancer wherever it is in the body. Modern chemotherapy is more precise, better supported and far more tolerable than the stories most families carry into the first consultation.

What chemotherapy actually does

Chemotherapy drugs attack cells that divide rapidly — which cancer cells do more than almost anything else in the body. It travels in the bloodstream, which is its unique power: it can reach cells that have broken away from the main tumour, which no operation can.

That is why it is used in three distinct ways: before surgery to shrink a tumour into operability, after surgery to destroy invisible leftover cells and cut the chance of the cancer returning, and as the main treatment where surgery is not the right tool.

What a course looks like

  • 01Cycles, not a continuous dripA treatment day, then two to three weeks of recovery at home — repeated, commonly for four to eight cycles
  • 02Mostly daycareMost cycles need a few hours in the day-care unit, not admission
  • 03Blood tests before each cycleCounts are checked so each dose is given only when the body is ready
  • 04Support medicines as standardModern anti-nausea drugs are given with every cycle, not on request
  • 05A named team watchingFever or any warning sign between cycles gets a phone line, not a waiting room

Side effects — the honest version

Expect fatigue for a few days after each cycle, and often taste change and reduced appetite. Nausea is now largely preventable with modern medication — vomiting through chemotherapy is a treatment failure we act on, not something to endure. Hair loss depends entirely on which drugs are used: some regimens cause it, many do not, and where it happens it is temporary. The one symptom that is never "normal" is fever — a temperature during chemotherapy is an emergency phone call, day or night.

Living during chemotherapy

Most patients continue much of normal life between cycles — many keep working with adjusted schedules. Eat what appeals, in small frequent meals; home food is fine and better than forced supplements. Avoid crowds in the low-count days your team identifies, and keep every follow-up blood test. Our patient guide on eating during chemotherapy covers the practical kitchen questions families actually ask.

Common questions

Is chemotherapy painful?
The infusion itself is not — it is a drip, and most people read, talk or sleep through it. Discomfort, where it comes, arrives in the following days as fatigue or taste change, and is managed cycle by cycle.
Will I definitely lose my hair?
No — it depends on the specific drugs. Some regimens spare hair entirely. You will be told before the first cycle what your particular combination usually does, and where hair falls it regrows after treatment.
Can an elderly patient tolerate chemotherapy?
Age alone is not the deciding factor — fitness is. Doses and drug choices are adjusted for older patients, and sometimes the honest recommendation is a gentler regimen or none at all. That assessment is individual, never assumed.
Is chemotherapy free under Ayushman Bharat?
For eligible families, yes — chemotherapy cycles, day-care administration and admission where needed are covered under PM-JAY packages, confirmed before the first cycle.
What is the difference between chemotherapy and targeted therapy?
Chemotherapy attacks all fast-dividing cells; targeted therapy blocks a specific mutation the tumour depends on, found by testing the biopsy. Many patients receive both at different stages — they are complementary tools, not competitors.
