Copper toxicity typically occurs with chronic intake above 1015mg daily over months, presenting as gastrointestinal distress, hepatic dysfunction, or zinc depletion
By reducing the activity of macrophages and impeding the infiltration of inflammatory elements into the brain parenchyma, bevacizumab contributes to a neuroprotective milieu (Genovese and Impellizzeri 2022)
