After finding a breast lump, i had a blood test that came back with normal blood count, is it still a possibility to have breast cancer?

Blood tests don't he: No blood tests would help to diagnose breast cancer. The only way to diagnose cancer is biopsy of the lump once it is confirmed to be real on an x-ray(mammogram). So you are advised to find a doctor who knows how to investigate a lump in breast , which most dcotors do. But a physical exam is the first step in order to decide if an x-ray or ultrasound is needed. Any palpable lump requires biopsy.
