I started having low back pain when I was 14 also. I'd recommend going to your family doctor. He'll be able to refer you to an orthopaedic doctor who will probably send you for x-ray's or an MRI. I really wouldn't worry that it's cancer. I had trouble bending & sitting; it was a mechanical problem. Feel better!

could it be also a kidney cancer?
