Colon and rectal cancer incidence was negligible before 1900. The incidence of colorectal cancer has been rising dramatically following economic development and industrialization.
Picture of the colon with colon cancer and colon polyps Tumors of the colon and rectum are growths (masses) arising from the wall of the large intestine. Benign tumors of the large intestine usually are called polyps because of their shape. Malignant tumors of the large intestine are cancers...

Rectal cancer is one of the most common cancers and the leading causes of death around the world1,2. Perineural invasion (PNI), malignant invasion of nervous structures and nerve sheaths that could be a source of metastatic spread beyond the extend of any local invasion, indicating an increased...
Neoadjuvant therapy for rectal cancer is used to down-stage tumors, reduce local recurrences, and improve survival. Pathologic response after nCRT has been shown to reduce recurrence and improve survival in patients [4,12]. Inflammatory response plays a significant role in tumor development, progress...
We retrospectively reviewed magnetic resonance (MR) images of 96 patients with diagnosis of rectal cancer to evaluate tumour stage (T stage), involvement of mesorectal fascia (MRF), and nodal metastasis (N stage). Our gold standard was histopathology. Al
Patients with rectal cancer who exercised while undergoing a form of tumor-shrinking radiation therapy in advance of surgery were more likely to have their tumors disappear, according to a University of Alberta study that begins to paint exercise as more than just a supportive care intervention. ...
However, in the present case, the initial tumors were not malignant but benign hamartomatous polyps, which were completely resected. Therefore, it is possible that the cancer in this case arose independently of the initial Peutz-Jeghers polyposis. On the other hand, given the high risk of ...

Total mesorectal excision for rectal cancer is a major operation associated with morbidity and mortality. For older or inoperable patients, alternatives are necessary. This prospective study evaluated the oncological and functional outcome and quality of
