The presacral space is the area between the rectum and lowest part of your spine (sacrum). A tumor is a growth in this area. It is rare but can be malignant (cancer).

A presacral tumor may be caused by:

  • Congenital factors (present from birth)
  • Hereditary disorders (eg, Currarino syndrome)
  • Other forms of cancer that have spread

Risk Factors

These factors increase your chance of a presacral tumor:

  • Gender: female
  • Age: 40-60 years


If you have any of these, do not assume it is due to a presacral tumor. These symptoms may be caused by other conditions. Talk to your doctor if you have:

  • Pain in the lower back or rectal/pelvic area
  • A feeling of heaviness
  • Constipation]]>
  • Overflow incontinence
  • Weight loss
In some cases, there are no symptoms.



Your doctor will ask about your symptoms and medical history. A physical exam will also be done with a digital rectal exam. Other tests may include:

  • X-ray]]>—uses radiation to take a picture of structures inside the body to locate the site and size of the tumor
  • ]]>CT scan]]>—a type of x-ray that uses a computer to make pictures of structures inside the body
  • ]]>MRI scan]]>—a test that uses magnetic waves to make pictures of structures inside the body



Talk with your doctor about the best plan for you. This will depend on the type of tumor you have. Treatment options include:

  • Surgery to remove the tumor
  • Chemotherapy]]>—If the tumor is cancerous, chemotherapy may be used. This involves using drugs to kill cancer cells.
  • Radiation therapy—This may be used along with chemotherapy. Radiation therapy involves using radiation to kill cancer cells and to shrink tumors.


There are no steps to prevent this condition.
