sometimes occurs during prostate cancer chemotherapy.
Some chemotherapy drugs, such as doxorubicin,
should not get out of the vein into which it is being
injected. If the drug does seep out, the patient experiences
extravasion injury, meaning the drug has invaded cells
outside of the vein. Prostate cancer patients with extravasion
injury may notice swelling, redness, or itching at the
site of extravasion injury.
