question: someone I know has just noticed blood in her urine, her symptoms are also diarrhoea, occasional vomiting, and pains in lower abdomen, she has a medical history of abnormal cells being removed twice in her cervix and she hasn t gone for a smear in 3 years. She s just recently had a urine test done and nothing has shown, she won t go back for more tests and I m worried. Is this serious?
