Glossary term · Treatment
Chemotherapy (also: Chemo): Chemotherapy is the use of drugs that kill or slow the growth of fast-dividing cancer cells, usually given in cycles of treatment and rest.
Chemotherapy is cancer treatment that uses drugs to kill cancer cells or slow their growth. The US National Cancer Institute says it targets fast-growing cells, which is why it can also affect healthy cells in the mouth, gut and hair. It is usually given in cycles of treatment and rest, often alongside surgery or radiotherapy.
How is chemotherapy given?
NCI lists several routes. The most common is intravenous, through a vein, often via a port or catheter. Others include tablets or liquids by mouth, injections into muscle or under the skin, and delivery into the spinal fluid, abdomen or an artery. It can be given during a hospital stay, as an outpatient or at home.
How is a chemotherapy plan chosen?
NCI says drug choice depends mainly on the type and stage of cancer, previous treatment and other health conditions such as diabetes or heart disease. Chemotherapy may be given before surgery to shrink a tumour (neoadjuvant) or after surgery to destroy remaining cells (adjuvant). It may also be used with other treatments or for cancer that has returned or spread.
What side effects are common?
NCI names fatigue as the most common side effect. Others include mouth sores, nausea and hair loss. Side effects often improve after treatment ends. They do not show whether chemotherapy is working. Doctors use blood tests and scans for that.
What should international patients agree in advance?
- Which parts of treatment will happen in India and which at home, and who supervises each.
- How blood counts will be checked between cycles.
- Which drugs will be used, and whether the same drugs are available in your home country.
- Who to contact urgently with fever or other warning signs after you return.
Many patients choose a cancer second opinion in India and then continue chemotherapy at home. The oncologist decides the treatment plan.
Questions people ask
Do I have to stay in India for every cycle?
Not always. Some patients receive all cycles in India and others start there and continue at home under a local oncologist. It depends on the regimen, your health and services at home. Agree a written plan before treatment starts.
Do side effects mean the treatment is working?
No. NCI says side effects do not indicate whether chemotherapy is working. Your oncologist uses blood tests and scans to assess response.
