Transverse colon cancer is a type of colon cancer. Generally speaking, in terms of diet, one should not eat spicy, stimulating, or hard-to-digest foods, such as overly spicy food, hot pot, smoked, grilled, or pickled foods. It is best to avoid these, as well as alcohol and tobacco. Because transverse colon cancer can lead to intestinal blockage as the tumor grows, consuming spicy, stimulating, or indigestible foods, or overeating and causing indigestion, can lead to intestinal obstruction. This is a relatively high risk, and typically, once transverse colon cancer is diagnosed, consideration should begin for primarily curative surgery.

Is upper gastrointestinal bleeding colon cancer?

Upper gastrointestinal bleeding cannot be caused by colon cancer, as the colon is part of the lower gastrointestinal tract. Therefore, upper gastrointestinal bleeding cannot result from colon cancer. There are several diseases that can cause upper gastrointestinal bleeding: The first common cause is peptic ulcer, including both gastric ulcers and duodenal ulcers, which can lead to bleeding in the upper gastrointestinal tract. The second cause is bleeding due to esophageal or gastric varices rupture associated with liver cirrhosis. This type of bleeding can be substantial and sometimes life-threatening. The third cause is acute gastric mucosal injury, such as that caused by heavy alcohol consumption or the use of nonsteroidal anti-inflammatory drugs (NSAIDs). The fourth cause is gastric cancer, which can lead to upper gastrointestinal tract bleeding. While colon cancer can cause rectal bleeding, it is not a cause of upper gastrointestinal tract bleeding.

Is colon cancer surgery a major surgery?

Colon cancer surgery is considered a relatively major procedure, ranking as a class three or four surgery in general surgery. Generally, it involves the resection of the entire transverse colon or tumors located in other areas such as the ascending or descending colon, accompanied by the removal of surrounding lymph nodes, followed by intestinal anastomosis and digestive tract reconstruction. Post-surgery, comprehensive anti-tumor treatment is usually required. After colon cancer surgery, the main focus is on preventing intestinal leakage, which is a serious complication. Dietary intake needs to be gradually restored after surgery. Initially, the patient may only be able to consume liquid and easily digestible foods, gradually transitioning to semi-liquid and regular diets, while also paying attention to eating smaller, more frequent meals.

Colon cancer surgical methods

The surgical approach for colon cancer should be tailored based on the specific circumstances of the patient, involving a rational, comprehensive treatment strategy. The surgical principle is that early-stage cancers should undergo curative resection, while more advanced cancers should be treated with radical surgery or extended radical surgery. Once the treatment plan is determined, the choice of surgical methods should be made comprehensively based on the patient's specific conditions. For example, in the surgery of rectal cancer in the middle and lower segments, it should be considered whether to preserve the anus or perform abdominoperineal resection based on the tumor's biological characteristics, patient's age, overall health, and any concurrent diseases. It is not that there is one fixed type of surgery; the approach should be specifically tailored based on the detailed analysis of the issues at hand.

Colorectal Cancer CT Manifestations and Differential Diagnosis

Early-stage colon cancer is difficult to clearly detect on a CT scan. In the moderate to late stages, colon cancer has more typical manifestations on CT, mainly characterized by thickening of the colon wall, irregular narrowing of the intestinal lumen, and stiffness of the intestinal wall. After enhancement, significant enhancement can be observed. The pericolonic fat space may appear blurred, and in the late stages, small lymph nodes can be seen, and even distant metastasis, most commonly to the liver, can be detected. It is necessary to differentiate colon cancer from colonic inflammation. Inflammatory lesions are usually more widespread and have typical clinical features such as fever and abdominal pain. It is also necessary to differentiate from lymphoma, as lymphomas also cause narrowing of the intestinal lumen but the narrowing is not eccentric and the intestinal wall remains soft, generally not leading to obstruction, whereas in late-stage colon cancer, colonic obstruction can be observed.

Is lower right abdominal pain colon cancer?

Pain in the lower right abdomen does not necessarily indicate colon cancer, as there are many possible causes of this pain. Common conditions include acute or chronic appendicitis, gynecological diseases such as pelvic inflammatory disease, torsion of a right ovarian cyst, ectopic pregnancy, and others. Additionally, urological issues like a stone in the lower part of the right ureter can cause severe pain in the lower right abdomen, which are again not indicative of colon cancer. Gastrointestinal diseases like Crohn's disease often lead to pain in the lower right abdomen. Of course, tumors in the ileocecal area or ascending colon can also cause such pain. Hence, while lower right abdominal pain is not necessarily due to colon cancer, in rare cases, it could be.
