The recent U.S study has shown that focused radiation can control the spread of cancer.

Researchers claim that the targeted radiation therapy can free patients from traces of cancer.
Researchers analyzed the data collected from ongoing clinical trails. Patients with stage- IV cancer with one to five distant metastases were included in the trails. The study included 29 patients with 56 cancerous lesions. Researchers found that targeted radiation therapy cured all signs of cancer in 21% patients.
