What should you know about stages of chemotherapy?

Before treatment, the oncology team confirms the purpose of chemotherapy, checks blood counts and organ function, and chooses medicines, doses and timing. A cycle may involve one or more treatment days, followed by time for the body to recover. The number of cycles depends on the cancer, the treatment goal and how your body responds.

Chemotherapy may be used before surgery to shrink a tumour, after surgery to treat cancer cells that may remain, or as the main treatment when surgery is not suitable. Scans, examinations and blood tests help the team decide whether to continue, adjust or complete the plan. The term stage of cancer describes spread; it is different from a chemotherapy cycle.

Keep a written record of treatment days, medicines and symptoms. Take only medicines approved by your oncology team, because some supplements and everyday drugs can alter treatment effects. Ask which symptoms need a same-day call and how to manage nausea, tiredness, mouth soreness or changes in bowel habits. Small meals, fluids as advised and gentle activity may help, but follow personalised instructions if your blood counts are low.

Contact your cancer team promptly for a fever, chills, new breathlessness, chest pain, confusion, uncontrolled vomiting, severe diarrhoea, unusual bleeding or an inability to drink. Do not wait for the next cycle review if symptoms are sudden or worsening. Emergency services are appropriate for severe breathing difficulty, collapse or chest pain.

Ask what each cycle is intended to achieve, how many cycles are planned, which tests will guide the next decision, and which symptoms require an urgent call. You can also ask whether treatment affects fertility, work, travel, vaccinations or other medicines.
