The most comprehensive Hospital in the Caribbean.

Auxilio Radiation Oncology Center 

The Auxilio Mutuo Radiation Oncology Center is one of the largest of its kind in the Caribbean, with very sophisticated and advanced technology. Our highly trained staff will assist our patients with all their needs in radiation and oncology treatments.

Patients feel comfortable and guided by the professional staff at the Center, comprised of a first class medical staff.

Dr. Vanessa Marcial, Board Certified, completed her Medicine degree at the University of Puerto Rico School of Medicine. She continued her studies in Radiology Oncology at the Hospital of the University of Pennsylvania, and she has been chosen for eight consecutive year for the Buena Vida Doctor's Choice Awards.

Dr. Robert Santiago, Board Certified, studied Medicine at the University of Puerto Rico School of Medicine. He continued his studies in Radiology Oncology at the Hospital of the University of Pennsylvania and has been recognized by the Buena Vida Doctor's Choice Award.

Our services include:

  • TrueBeam - one of the most advanced systems for radiation therapy and radiosurgery. With this technology, Physicians can design the treatment for each patient's specific medical needs. For more information, you can visit
  • Calypso Systems, GPS for the Body - is the only one of its kind in Puerto Rico and the Caribbean for prostate cancer treatment. For more information, you can visit and
  • Three-Dimensional Conformal Radiation Therapy (3D-CRT) - uses computers and special imaging techniques such as CT, MR or PET scans to show the size, shape and location of the tumor as well as the surrounding organs. The radiation beams are very precisely directed, normal tissues nearby receive less radiation and it is able to heal more quickly.
  • Intensity Modulated Radiation Therapy (IMRT) - specialized form of 3D-CRT that allows radiation to be more of an exact shape to fit the tumor. With IMRT, the radiation can be broken up into many "beamlets" and the intensity of each beamlet can be adjusted individually.
  • Image Guided Radiation Therapy (IGRT) - involves conformal radiation treatment guided such as a CT, ultrasound or X-rays, taken in the treatment room just before the patient is given the radiation on a daily basis. These images are compared to the first images of the CT scan taken as part of the planning process.
  • Stereotactic Radiation Therapy - This is a specialized technique that allows radiation oncologists to use extremely focused beams of radiation to destroy certain types of tumors using higher doses than with the daily radiation treatments. The beam is so precise that they will be able to spare more healthy tissue. This therapy is often used for the lung, spine or liver. It may allow radiation to be given in a way that is safer and more effective than any other radiation technique.
  • Brachytherapy - is the placement of radioactive sources in or right next to the tumor. High-dose rate (HDR) brachytherapy involves the remote placement of the powerful radiation source, accurately directed by your radiation oncologist and team, into the tumor for several minutes through a tube called a catheter.
  • Calypso - delivers precision and accuracy, continuously and in real time during each treatment. It detects even the slightest movement of the prostate using radiofrequency waves with three electromagnetic transponders permanently implanted into the prostate.
