Symptoms of Chordoma
Chordomas are tumors that can occur anywhere within the spine or the base of the skull. The two most common locations for chordomas are the lower back (sacral area - approximately one-third to one-half of chordomas) and the base of the skull (approximately one-third of chordomas). Chordomas form from remnants of the notochord - embryonic tissue that eventually forms the center of spinal disks.

What are the symptoms of chordoma?
Chordomas can press on the spine, brain and nerves as they grow, causing pain and nerve problems specific to the part of the brain or spinal cord where they are located. These symptoms can include tingling, numbness, weakness, lack of bladder or bowel control, sexual dysfunction, vision problems, endocrine problems and swallowing difficulties. If the chordoma has grown very large, you may be able to feel a lump.
