Radiology & Imaging in Cancer Diagnosis & Therapy

Radiation therapy uses great energy element or radiation or waves such as x-rays, gamma rays, electron beams, protons to abolish or shrink Cancer cell. When compared to normal cell, the Cancer cells grow and split faster, radiation works by making minor breaks in the DNA inside the cells. Cancer cells whose DNA is damaged by radiation stops dividing or die. The normal cell current nearby Cancer cells can also be affected by radiation, leading to side effects. Radiation therapy may be used alone or in combination with surgery Immunotherapy and Chemotherapy. The radiation can be given in 3 ways dependent upon the type of Cancer and position. Types of radiation are external radiation, internal radiation, systemic radiation and others.

Cancer Imaging is the term that covers many methods used in diagnoses and Research Cancer. It is initially used to diagnose and stage the disease and now it is also used to assist with surgery and Radiotherapy, to recognise patients who are responding to treatment and to look for early responses.
