The Pacific Cancer Institute (PCI) provides state-of-the art radiation therapy treatments using the TrueBeam™ STx system. The technology is able to deliver standard external beam radiation treatments, intensity-modulated radiation therapy (IMRT) and stereotactic radiosurgery (SRS/SBRT) with onboard image guidance. Our system combined with our skilled team of professionals delivers precise and accurate radiation to a tumor target.

Typically radiation therapy treatments are delivered over a course of days with the intent to damage cancer cells by destroying the genetic material that controls how the cells grow and divide and spare normal tissue as much as possible. The specific number of treatments and amount of radiation is determined by the radiation oncologist using the latest research information available.

Your physician may refer you to PCI for a radiation therapy consultation as an option at different times during your cancer journey and for different reasons, including but not limited to the following:

  • A primary, nonsurgical treatment for cancer
  • To treat advanced stage tumors or lesions (metastatic)
  • To shrink the size of a tumor prior to surgery for a tumor
  • After surgery, to treat the area where a tumor was removed
  • In combination with other treatments such as chemotherapy, immunotherapy

A personalized consultation with our radiation oncologist for your specific diagnosis, including a review of all your treatment options with a detailed discussion on the risk and benefits of radiation therapy, is the first step in providing the best possible outcome for you. We strive to present you with the best information available so you can make the best decision for yourself and your specific circumstance. Our goal is to empower you so you assist driving your care.

Bone cancer

An abnormal growth of cells within a bone that may be cancerous or benign.

Brain tumor

An abnormal growth of tissue (tumor) in the brain that may be cancerous or non-cancerous.

Breast cancer

A disease in which malignant (cancer) cells form in the tissues of the breast.


A malignant type of bone cancer that primarily affects the cartilage cells of the femur (thighbone), arm, pelvis, knee, and spine. Although less frequent, other areas (such as the ribs) may be affected.

Metastatic brain cancer

An abnormal growth of tissue (tumor) in the brain that travels from another part of the body to the brain (metastasize).


A type of tumor that grows from the protective membranes, called meninges, which surround the brain and spinal cord, and is often benign and slow growing.

Non-Hodgkin’s lymphoma

A type of cancer of the lymphatic system which can begin in almost any part of the body, causing cells to abnormally reproduce and tumors to eventually grow.


A type of bone cancer, most often occurring in children, adolescents, and young adults, that develops in the osteoblast cells that form the outer covering of bone.

Pancreatic cancer

Cancers that begin in the pancreas.

Paranasal sinus cancer

A type of malignant cancer in the tissues of the paranasal sinuses or nasal cavity.

Prostate cancer

A type of cancer that occurs when cells grow abnormally in the prostate gland and form tumors.

Head and neck cancers

Benign and malignant tumors that originate in the head and neck region, including sarcomas and nerve or lymph node conditions.

Soft tissue sarcomas

A rare cancer in one of the soft tissues. There are many different kinds of soft tissue sarcoma. In general, soft tissue sarcomas are rare.

Spinal cord tumors, spine tumors

A tumor that forms on the spinal cord or in the area around it. Even if benign, the tumor may cause pain, weakness, numbness, or tingling from pushing on the spinal cord or nerves.
