Causes of GI cancer

The causes of gastrointestinal cancers include:

  • Smoking

Treatment of this type of cancer depends on many factors such as type of cancer, stage and other general health factors. The two major treatment options for GI cancers are chemotherapy and radiation therapy.

  • ​Radiation Therapy –To treat gastrointestinal cancers, IMRT (intensity modulated radiation therapy) is widely used            which enables high accuracy while ensuring minimal damage to other organs like liver, kidneys, and spinal cord.              Moreover, IMRT allows doctors to deliver radiation to hard-to-reach areas.
