 Frequently Asked Questions About Cancer Care

We know that many people have questions about the different types of cancer treatments we provide. Below you will find a few brief descriptions of many of our services.

What is Radiation Therapy?
Radiation therapy, including IMRT, stops cancer cells from dividing and growing, thus slowing tumor growth. In many cases, radiation therapy is capable of killing cancer cells, thus shrinking or eliminating tumors.

What is External Beam Radiation Therapy (EBRT)?
External beam therapy (EBT) is a method for delivering a beam of high-energy x-rays to the location of the patient's tumor. The beam is generated outside the patient (usually by a linear accelerator, see below) and is targeted at the tumor site. These x-rays can destroy the cancer cells and careful treatment planning allows the surrounding normal tissues to be spared. No radioactive sources are placed inside the patient's body.

What is Intensity-Modulated Radation Therapy (IMRT)?
Intensity-modulated radiation therapy (IMRT) is an advanced mode of high-precision radiotherapy that utilizes computer-controlled x-ray accelerators to deliver precise radiation doses to a malignant tumor or specific areas within the tumor. The radiation dose is designed to conform to the three-dimensional (3-D) shape of the tumor by modulating—or controlling—the intensity of the radiation beam to focus a higher radiation dose to the tumor while minimizing radiation exposure to surrounding normal tissues.

What is Brachytherapy?
Brachytherapy is a one time treatment option for men with localized (confined to the organ) prostate cancer. The procedure might also be considered for men whose age or medical conditions make other treatment options a risk.

What is High Dose Rate Brachytherapy?
High-dose-rate (HDR) brachytherapy delivers high-intensity radiation directly into tumors through fine needles that are deployed from computer-controlled afterloaders that move the radiation source on a wire within the needle according to a prescribed treatment plan. The total dose is delivered in a series of fractions, or treatment sessions.

What is PET/CT?
Positron Emission Tomography (PET) and Computerized Tomography (CT) are both standard imaging tools that allow physicians to pinpoint the location of cancer within the body before making treatment recommendations.

The highly sensitive PET scan detects the metabolic signal of actively growing cancer cells in the body and the CT scan provides a detailed picture of the internal anatomy that reveals the location, size and shape of abnormal cancerous growths. Alone, each imaging test has particular benefits and limitations but when the results of PET and CT scans are "fused" together, the combined image provides complete information on cancer location and metabolism.

What is chemotherapy?
Chemotherapy is the use of medicines (or drugs) to treat disease. Sometimes this type of treatment is called just "chemo." Although surgery and radiation therapy remove, destroy, or damage cancer cells in a specific area, chemotherapy works throughout the body. Chemotherapy can destroy cancer cells that have metastasized, or spread to parts of the body far away from the primary (original) tumor.

Does CCNT have access to the latest research protocols?
CCNT has access to national and international research in cancer prevention, detection, and treatment.

What is Mammosite?
The MammoSite® RTS is a new minimally invasive method of delivering internal radiation therapy following a lumpectomy for breast cancer. Therapy is given on an outpatient basis-there is no need to stay in the hospital-and can be completed in 5 days. The MammoSite® RTS is a single small balloon catheter that fits inside the tumor resection cavity-the space that is left after the surgeon removes the tumor. A tiny radioactive seed, connected to a machine called an afterloader, is inserted into the balloon and delivers the radiation therapy.

What is SAVI?
SAVI uses a bundle of tubes (catheters) to deliver radiation from inside the breast. The catheters expand to fit the size and shape of the cavity, and a tiny radioactive seed is placed in each catheter.This allows every catherer to deliver an individual dose of radiation, so your physician can customize treatment just for you, regardless of the size, shape or location of your lumpectomy cavity. Treatment is delivered twice a day for 5 days.
