The chemotherapy can reduce the production of white blood cells by the bone marrow, making you more likely to get an infection. This effect can begin seven days after treatment has been given and your resistance to infection usually reaches its lowest point 10–14 days after chemotherapy. Your blood cells will then increase steadily and will usually have returned to normal before your next course of chemotherapy is due.
Contact your doctor or the hospital straightaway if:

• Your temperature goes above 38ºC (100.5ºF)
• You suddenly feel unwell (even with a normal temperature).

You will have a blood test before having more chemotherapy, to make sure that your cells have recovered. Occasionally it may be necessary to delay your treatment if your blood count is still low.
