What is Chemotherapy? (Definition and Meaning)
Chemotherapy, often shortened to ‘chemo’, is a medical treatment that uses cytotoxic drugs to destroy cancer cells or stop them from reproducing. It is one of the most widely used cancer treatments across a broad range of cancer types and stages. Kimo Treatment / Kimo Injection – Same as Chemotherapy In India, chemotherapy is commonly called ‘kimo’, ‘kimo treatment’, or ‘kimo injection’ – phonetic renderings of ‘chemo’. All terms refer to the same treatment: using cytotoxic drugs to kill cancer cells. Whether your doctor has referred to it as chemotherapy or kimo, it is the same procedure.How Does Chemotherapy Work?
Chemotherapy works by targeting cells that divide rapidly. Cancer cells typically divide much faster than normal cells, making them more vulnerable to cytotoxic drugs. Depending on the drug, chemotherapy can: damage the cancer cell’s DNA to prevent it from copying itself; disrupt the cell cycle at a specific point; or block nutrients a cancer cell needs to grow. The result is programmed cell death, called apoptosis. Some healthy cells that also divide rapidly – such as hair follicle cells, bone marrow cells, and the digestive tract lining – can be temporarily affected, which explains common side effects. Most of these effects are temporary and resolve after treatment ends.When is Chemotherapy Used? Goals and Clinical Indications
Chemotherapy is recommended when cancer cells need to be targeted throughout the body. The specific goal determines when and how it is given:- Curative chemotherapy: given with the intent to eliminate the cancer completely. Used for highly chemosensitive cancers such as leukaemia, lymphoma, and some solid tumours.
- Neoadjuvant chemotherapy: given before surgery or radiation to shrink the tumour and reduce the extent of the operation.
- Adjuvant chemotherapy: given after surgery or radiation to destroy residual cancer cells and reduce the risk of recurrence.
- Palliative chemotherapy: given when a cure is not the primary goal – slows disease spread, relieves symptoms, and improves quality of life.
- Concurrent chemoradiation: chemotherapy given alongside radiation to make cancer cells more sensitive. Used for head and neck, oesophageal, and cervical cancers.
Types of Chemotherapy: Classification and Drug Classes
Chemotherapy is classified by delivery route, timing relative to other treatments, and drug class.By Route of Delivery
- Systemic chemotherapy (IV or oral): drugs circulate through the bloodstream, reaching cancer cells throughout the body.
- Regional chemotherapy: drugs are delivered to a specific body cavity – e.g., intraperitoneal for abdominal cancers, or intrathecal for CNS cancers.
Common Chemotherapy Drug Classes
- Alkylating agents: damage DNA to prevent cell replication. Examples: cyclophosphamide, cisplatin, carboplatin.
- Antimetabolites: block DNA/RNA synthesis. Examples: methotrexate, 5-fluorouracil (5-FU), gemcitabine.
- Anthracyclines: intercalate into DNA. Examples: doxorubicin, epirubicin.
- Taxanes: prevent cell division by stabilising microtubules. Examples: paclitaxel, docetaxel.
- Topoisomerase inhibitors: block enzymes needed for DNA replication. Examples: irinotecan, etoposide.
What Happens During Chemotherapy: Step-by-Step
Chemotherapy is a carefully planned, multi-step process overseen by a medical oncologist and a chemotherapy nursing team.How to Prepare for Chemotherapy
Before starting, your oncologist will confirm blood counts, kidney and liver function, and heart function to ensure you are fit for the regimen. A dental check is important to address any potential infection sources. A PICC line or implanted port may be placed to simplify intravenous access throughout the treatment course.What to Expect During a Chemotherapy Session
Most standard chemotherapy at Onco-Life Cancer Centre is delivered as daycare admission – you come in for the infusion and return home the same day. IV infusions are given through a drip, catheter, or port; oral chemotherapy is taken as tablets at home. Sessions can last from 30 minutes to several hours depending on the regimen. During the session, your vital signs are monitored and a nurse is present throughout.Chemotherapy Cycles and Duration
Chemotherapy is given in cycles, with a treatment session followed by a rest period that allows healthy cells to recover. A typical cycle is 2 to 4 weeks. Most treatment courses involve 4 to 8 cycles over several months. Your oncologist will explain your specific schedule.Benefits of Chemotherapy
Chemotherapy’s main benefits are its ability to reach cancer cells anywhere in the body (systemic treatment), its applicability across many cancer types and stages, its ability to shrink tumours before surgery, and its role in reducing recurrence risk after surgery. For advanced cancers, chemotherapy can meaningfully extend life and relieve cancer-related symptoms.Chemotherapy Side Effects: What to Expect and How They are Managed
Chemotherapy side effects occur because some healthy cells that divide rapidly are temporarily affected. Common side effects include:- Fatigue: the most common general side effect; usually builds during treatment and improves over weeks after the course ends.
- Nausea and vomiting: manageable with anti-nausea medications (antiemetics); most patients do not experience severe nausea with modern supportive care.
- Hair loss (alopecia): occurs with some but not all chemotherapy drugs; hair normally regrows after treatment ends.
- Increased infection risk (neutropenia): low white blood cell count makes infections more likely; fever above 38°C during chemotherapy requires prompt medical attention.
- Anaemia and fatigue from low red blood cells: managed with dietary support and, in some cases, growth factors or transfusions.
- Mouth sores (mucositis): oral hygiene and specific mouth rinses help prevent and manage this side effect.

Frequently Asked Questions
Chemotherapy: What It Is, How It Works and Types | Onco-Life Hospitals FAQs
What Is Chemotherapy And What Does It Do?
Chemotherapy is a cancer treatment that uses cytotoxic (cell-killing) drugs to destroy cancer cells or prevent them from reproducing. The drugs travel through the bloodstream, reaching cancer cells throughout the body. Chemotherapy can be used to cure cancer, reduce the risk of recurrence after surgery, shrink a tumour before surgery, or slow the spread of advanced cancer and relieve symptoms.
How Does Chemotherapy Work To Treat Cancer?
Chemotherapy targets cells that divide rapidly. Cancer cells divide much faster than most normal cells, making them more susceptible to cytotoxic drugs. The drugs work by damaging cancer cell DNA, disrupting the cell cycle, or blocking nutrients the cell needs to grow - ultimately causing the cancer cell to die. Because some healthy rapidly-dividing cells are also affected (for example, hair follicles and bone marrow), side effects occur during treatment.
What Are The Types Of Chemotherapy Drugs?
Chemotherapy drugs are classified into groups based on how they work: alkylating agents (e.g., cyclophosphamide, cisplatin), antimetabolites (e.g., 5-fluorouracil, methotrexate), anthracyclines (e.g., doxorubicin), taxanes (e.g., paclitaxel, docetaxel), and topoisomerase inhibitors (e.g., irinotecan). Your oncologist selects a regimen based on the cancer type and stage.
What Is Kimo Treatment? Is It The Same As Chemotherapy?
Yes. 'Kimo' or 'kimo treatment' is a phonetic rendering of 'chemo' used commonly in India. It refers to the same treatment: chemotherapy using cytotoxic drugs to kill cancer cells. Whether your doctor has said chemotherapy, chemo, or kimo - it is the same medical procedure.
Is Chemotherapy Available Under MJPJAY Or Ayushman Bharat?
Yes. Onco-Life Cancer Centre is empanelled with MJPJAY, PM-JAY (Ayushman Bharat), and CGHS. Eligible patients may access chemotherapy and related treatments on a cashless basis. Eligibility criteria apply; please contact the Onco-Life TPA desk to verify your eligibility before treatment begins.
How Long Does A Chemotherapy Session Take?
Each chemotherapy session typically lasts between 30 minutes and several hours depending on the drug regimen and delivery method. Most standard regimens at Onco-Life Cancer Centre are given as daycare (same-day) admissions. Oral chemotherapy is taken at home as tablets. Your oncologist will explain the specific schedule for your regimen.
What Are The Most Common Chemotherapy Side Effects?
Common side effects include fatigue, nausea and vomiting, hair loss (with some drugs), increased infection risk due to low white blood cell counts, anemia, and mouth sores. Most side effects are temporary and managed with supportive care medications and dietary advice. Fever above 38°C during chemotherapy should be reported to the oncology team promptly.
Can Chemotherapy Cure Cancer?
Chemotherapy can cure some cancers - particularly leukaemia, lymphoma, testicular cancer, and certain other cancers when detected at an early or intermediate stage. For other cancers, it may not cure the disease but can control its spread or relieve symptoms. Whether chemotherapy is used with curative intent depends on the cancer type, stage, and individual factors. Your oncologist can discuss the goals of your specific treatment.
