PubMed Health : ⁶³ Colorectal cancer: Colorectal (bowel) cancer is one of the more common forms of cancer in many countries, including Germany. The name "colorectal cancer" is used to describe bowel cancer that starts in the colon (the large intestine) or the rectum. Cancer of the small intestine is very rare. Colorectal cancer almost always develops from growths called colorectal polyps that form in the lining of the colon. But by no means do all polyps become cancerous – and if a polyp does become cancerous, it takes many years. One way to prevent colorectal cancer is to have a colonoscopy, which also allows doctors to remove polyps. Having colorectal cancer can be a life-changing experience. What happens after the diagnosis has been made will depend on various factors, including the stage of the cancer. In early-stage colorectal cancer, the tumor just needs to be surgically removed. In advanced stages, additional treatments may be considered, such as chemotherapy or radiation therapy. In Germany, high-quality medical care is available for people who have cancer. There are also a number of sources of support, for instance to help cope with the disease emotionally and make it easier to go back to work.

MalaCards based summary: Colorectal Cancer, also known as colon cancer, is related to lynch syndrome and colonic benign neoplasm, and has symptoms including nausea and vomiting, constipation and abdominal pain. An important gene associated with Colorectal Cancer is CTNNB1 (Catenin Beta 1), and among its related pathways/superpathways are Disease and ERK Signaling. The drugs Ketamine and Tramadol have been mentioned in the context of this disorder. Affiliated tissues include colon, rectum and liver, and related phenotypes are renal cell carcinoma and neoplasm of the stomach

MedlinePlus: ⁴¹ The colon and rectum are part of the large intestine. Colorectal cancer occurs when tumors form in the lining of the large intestine. It is common in both men and women. The risk of developing colorectal cancer rises after age 50. You're also more likely to get it if you have colorectal polyps, a family history of colorectal cancer, ulcerative colitis or Crohn's disease, eat a diet high in fat, or smoke. Symptoms of colorectal cancer include: Diarrhea or constipation A feeling that your bowel does not empty completely Blood (either bright red or very dark) in your stool Stools that are narrower than usual Frequent gas pains or cramps, or feeling full or bloated Weight loss with no known reason Fatigue Nausea or vomiting Because you may not have symptoms at first, it's important to have screening tests. Everyone over 45 should get screened. Tests include colonoscopy and tests for blood in the stool. Treatments for colorectal cancer include surgery, chemotherapy, radiation, or a combination. Surgery can usually cure it when it is found early. NIH: National Cancer Institute

CDC: ² Colorectal cancer is cancer that occurs in the colon or rectum. Sometimes it is called colon cancer, for short. As the drawing shows, the colon is the large intestine or large bowel. The rectum is the passageway that connects the colon to the anus. Sometimes abnormal growths, called polyps, form in the colon or rectum. Over time, some polyps may turn into cancer. Screening tests can find polyps so they can be removed before turning into cancer. Screening also helps find colorectal cancer at an early stage, when treatment works best.

OMIM®: ⁵⁷ Colorectal cancer is a heterogeneous disease that is common in both men and women. In addition to lifestyle and environmental risk factors, gene defects can contribute to an inherited predisposition to CRC. CRC is caused by changes in different molecular pathogenic pathways, such as chromosomal instability, CpG island methylator phenotype, and microsatellite instability. Chromosome instability is the most common alteration and is present in almost 85% of all cases (review by Schweiger et al., 2013). (114500) (Updated 08-Dec-2022)

UniProtKB/Swiss-Prot: ⁷³ A complex disease characterized by malignant lesions arising from the inner wall of the large intestine (the colon) and the rectum. Genetic alterations are often associated with progression from premalignant lesion (adenoma) to invasive adenocarcinoma. Risk factors for cancer of the colon and rectum include colon polyps, long-standing ulcerative colitis, and genetic family history.
