Red flags useful to screen for suspect cancer in patients with low back pain: a scoping review protocol

Low back pain (LBP) is defined as pain and discomfort occurring under the costal arch and above the inferior gluteal folds, with or without leg pain. The most common type of low back pain is “non-specific low back pain”. It is defined as such because there is no specific pathology that can be the cause. Instead, “specific low back pain” is caused by diseases such as infections, tumors, osteoporosis, ankylosing spondylitis, fractures, inflammatory processes, radicular syndromes, cauda equina syndrome, etc. It is the most common musculoskeletal disorder in the world and the most cause of disability.
