My mum had a biopsy on Wednesday for her bladder. She had/has tumors and she had to have treatment over 6 weeks to get rid of them. This entailed putting Tb dye into her system, which has hopefully done the trick. Awaiting the results.

My question is, she has started having bad chest pains. She thinks it's a chest infection from the procedure. Is this likely or could it be something more serious relating to the tumor? She says it feels like someone is stabbing her in the back.
