Lymphoma survivors who were treated with prior radiation therapy have been shown to have an increased risk of cancers of the gastrointestinal system. This increased cancer risk may be due to damage to cells in your gastrointestinal system that is caused at the time of radiation. This research is being conducted to evaluate the use of enhanced gastrointestinal cancer screening in lymphoma survivors who have been treated with prior radiation therapy. We want to determine if enhanced gastrointestinal cancer screening can detect precancerous lesions and cancers in this population of patients.

You may be eligible for this study if you meet the following criteria:

• Conditions: Gastrointestinal Cancer, lymphoma
• Age: 99 years or below
• Gender: All
