During chemotherapy, the reason for high white blood cell count is generally due to inflammation. Treatment can be based on the cause of inflammation, and antibiotics can be used. However, if it is an infection, such as an abscess, it may require incision and drainage. Sometimes, white blood cell counts may fluctuate slightly. If there is an increase, it indicates an infection. Generally, there may be a slight increase after chemotherapy, and attention should be paid to it. Here are some reasons for the increase in white blood cell count during chemotherapy:

1. Reasons for increased white blood cell count during chemotherapy

There are many reasons for the increase in white blood cell count during chemotherapy. For example, some chemotherapy drugs, such as taxanes and gemcitabine, require the use of hormones before chemotherapy to prevent allergies. Hormones are also used to reduce gastrointestinal side effects such as severe vomiting and decreased appetite. Hormones can stressfully cause an increase in white blood cell count.

2. Rare occurrence of increased white blood cell count after chemotherapy

Generally, there is a very low chance of an increase in white blood cell count after chemotherapy. If there is an increase, the following reasons may apply: Chemotherapy drugs have little effect on the blood system and do not cause significant changes in white blood cell count. The use of glucocorticoids during chemotherapy can lead to an increase in white blood cell count. Preventive use of drugs that increase white blood cell count, such as recombinant human granulocyte colony-stimulating factor, can also cause an increase in white blood cell count.
