Colorectal cancer affects the lower portion of the gastrointestinal system and kills approximately 50,000 Americans each year according to theNational Cancer Institute. Treatment depends on the exact location of the tumor, whether metastasis has occurred, and the overall condition of the patient. Inoperable tumors are those that cannot be safely removed due to proximity to other structures, extent of spread, and surgical risks outweighing the benefit of tumor removal in the case of advanced cancers. Not being able to remove the tumor can allow it to obstruct the gastrointestinal outflow, causing blockage of the colon and/or rectum.
