Does chordoma run in families?
Does chordoma run in families?
About twice as many men are diagnosed with chordoma as women. While chordoma can run in families, this is very rare (see “Are there risk factors for chordoma?” section below).
What causes a chordoma?
The underlying causes of chordoma are unknown. Most cases arise spontaneously and are not due to an inherited genetic change. A prevailing theory is that acquired genetic abnormalities or mutations result in cancerous growth of notochordal remnants.
Are chordomas rare?
Chordomas are rare malignant (cancerous) tumors that are found in the spine and skull. These tumors affect about 1 person in 1 million people per year. One to four percent of all primary bone tumors are chordomas.
How do you know if you have chordoma?
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.
Can you feel a chordoma tumor?
Because chordomas grow very slowly, they may start with subtle symptoms, or it may take years for any noticeable symptoms to appear. Some people feel a lump along their spine or at the base of the skull, while others may feel pain or pressure in nearby parts of the body that are affected by the growing chordoma.
What is a clival chordoma?
A chordoma is a rare type of cancerous bone tumor that can occur at any part of the spine or in the skull. Most of these tumors are found in adults aged 40 to 70 years old. One example is a clival chordoma. Figure 1. Anterior, lateral and posterior views of the spine
Where does chordoma form on the skull?
It most often forms where the skull sits atop the spine (skull base) or at the bottom of the spine (sacrum). Chordoma begins in cells that once made up a collection of cells in the developing embryo that go on to become the disks of the spine. Most of these cells go away by the time you’re born or soon after.
What are the symptoms of chordoma?
When chordoma starts at the base of the skull you may have headaches or double vision. Chordoma near the tailbone can cause pain down your legs and trouble controlling your bladder or bowels. Imaging: When you have symptoms of chordoma, your doctor will take an image of your spine using an MRI to look at the size of the tumor and where it is.
What is the most common location for chordomas?
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.
