NYP Treats Cancer With Pinpoint Precision

In 1895, German physicist Wilhelm Conrad Roentgen first produced x-rays, ushering in an era of radiation science. More than a century later, a wide array of radiation therapy approaches have been developed to shrink and destroy cancerous tumors.

Since radiation was first harnessed to treat cancer, radiation oncologists -- the doctors who oversee patients' radiation therapy -- have grappled with its side effects. Because x-ray radiation scatters, healthy tissue near a tumor can be damaged, resulting in irritation and other side effects during treatment and beyond.

The good news is that doctors currently have access to the most precise radiation therapy ever developed, from shaping radiation beams to the contours of tumors to focusing higher doses of radiation into tumor tissue.

Advances in therapy include:

  • Intensity-modulated radiation therapy: IMRT enables doctors to direct radiation of different intensities to different parts of the tumor. The goal is to increase the radiation dose to selected areas and reduce exposure to sensitive areas of surrounding normal tissue.
  • Image-guided radiation therapy: During IGRT, imaging scans are analyzed as the patient progresses through treatment to identify changes in tumor size and adjust the radiation dose accordingly. Repeated maging scans can increase the accuracy of each radiation treatment and reduce the total radiation dose.
  • Stereotactic radiosurgery and radiotherapy: A very high, precise dose of radiation is used to quickly treat small tumors with well-defined edges. This technique is used to treat brain and spine tumors as well as cancers of the lung, liver and pancreas.
  • Prone radiation therapy for breast cancer: During treatment, a woman lies on her stomach with the breasts exposed to radiation through an opening in the table, sparing the lungs and heart from radiation exposure.
  • Brachytherapy: Radioactive implants, such as tiny seeds, are surgically placed internally to deliver radiation directly to a tumor site.
