Bank Statement in English

Hello I have a question, I need a bank statement from the last 3 months for my ED Muaythai Visa, but the problem is that my bank is portuguese and I have to translate my all my bank statement by a certified place/person, do I have to translate all the pages ? Because there is a lot of publicity in my bank statements and no relevant informations, and if so I would have to pay a lot just to translate ( my bank is Santander Totta)
