What should you know about chemo for prostate cancer?

These medicines move through the bloodstream and damage rapidly dividing cells. The aim may be to slow cancer growth, ease cancer-related symptoms, or strengthen overall disease control. Chemotherapy is not needed for every prostate cancer diagnosis; the decision depends on where the cancer is, how it has responded to other treatment, your general health, and your preferences.

An oncology team may consider chemotherapy when prostate cancer has reached other parts of the body or is progressing despite medicines that reduce or block testosterone. In some situations, it is offered together with hormone therapy earlier in the treatment plan. It is a whole-body treatment, unlike surgery or radiotherapy directed at a particular area.

Treatment is usually given in cycles, with medicine on scheduled days and recovery time between visits. Blood tests before treatment help the team check blood-cell counts and organ function. Side effects vary with the medicine and dose, but can include tiredness, nausea, mouth soreness, hair loss, increased infection risk, easy bruising, and tingling or numbness in the hands or feet. Supportive medicines and dose adjustments can help manage some effects.

Before the first cycle, give the oncology team a complete list of prescription medicines, over-the-counter products, vitamins, and herbal supplements because some can interact with treatment. Ask for the treatment schedule, the after-hours contact number, and the exact temperature threshold that should trigger a call. Arrange transport or practical help if fatigue is expected.

During treatment, take anti-nausea and other supportive medicines as directed, drink enough fluid unless you have been given a restriction, and report side effects early. Use gentle mouth care and avoid starting painkillers or fever-reducing medicine for a new fever until the cancer team advises you, because it can hide a sign of infection. Keep the treatment alert information with you when visiting another clinic or emergency department.

Contact the oncology team immediately if you develop a fever at or above the threshold they gave you, shaking chills, a sore throat, a new cough, burning when passing urine, diarrhoea, or sudden unexplained illness. Chemotherapy can lower infection-fighting white blood cells, so infection symptoms need prompt assessment even if they seem mild. Do not wait for the next appointment.

Call emergency services for severe trouble breathing, chest pain, confusion, collapse, coughing up blood, or bleeding that will not stop. Persistent vomiting, inability to keep fluids down, severe diarrhoea, or rapidly worsening weakness also warrants urgent advice from the cancer team.

Ask what chemotherapy is intended to achieve in your situation, which medicine is proposed, and how the team will judge whether it is helping. Other useful questions cover expected side effects, effects on existing medical conditions, fertility or sexual health concerns, work and driving, and who to call outside clinic hours. If other treatments are available, ask how their goals and side effects compare with chemotherapy.
