The internal radiation therapy is also known as brachytherapy. The procedure is carried out when radioactive elements are situated in the cancer or its nearby tissues. Some of these radioactive implants are temporary while others are permanent.

Safety Measures for Radiation Therapy

Even though radiation therapy has been a common cancer treatment practice for over a century, doctors are particular about the therapy.

  • Pregnant women or minors are not recommended to visit radiation therapy patients for some time
