Colon cancer often does not have obvious symptoms in its early stages, and of course, the specific situation needs to be analyzed on a case-by-case basis, as it varies from person to person. As the disease progresses, some clinical symptoms may appear. The first one is changes in bowel habits and stool characteristics; there might be blood in the stool, changes such as an increased frequency of defecation, urgency followed by a feeling of incomplete evacuation, and a sensation of rectal fullness, along with possible changes in the shape or thinning of the stool. The second possible symptom is abdominal pain, which may also be accompanied by a feeling of bloating or abdominal discomfort. The third possibility is the symptoms of intestinal obstruction, which include cessation of bowel movements and passing gas. The fourth is that a mass may be felt in the abdomen. The fifth point is that some individuals, especially those in poor health, may experience symptoms of nutritional depletion from the tumor, such as anemia, weight loss, and fatigue. If there is early metastasis, symptoms corresponding to the metastasis may also appear.

How long can one live after colon cancer surgery?

If colon cancer can be treated surgically, generally, the outcomes might be quite good. It often applies to cancer in relatively early stages, with potentials to survive for over three years, five years, or even longer. Of course, there are cases of colon cancer that are discovered in later stages, where complete surgical removal is not possible, and only palliative stoma surgery can be performed. In such situations, the survival time might be within three to five years, but the exact life expectancy cannot be fully determined. Each individual's condition is different, and treatment must be adapted accordingly. Typically after surgery, treatments like chemotherapy, radiation therapy, and targeted therapy might be used in combination to prolong survival.

What should not be eaten with transverse colon cancer?

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 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.

Can baby's stool with blood be colon cancer?

Blood in the stool of babies is different from that in adults. In infants and young children, due to weaker gastrointestinal digestive functions, inappropriate feeding, changes in diet structure, or abnormal gastrointestinal functions can all lead to the presence of blood in the stool, which is usually not due to colon cancer. Therefore, if a child has persistent blood in their stool accompanied by either no weight gain or weight loss, or other abnormal symptoms, and if there is a suspicion of cancer-related factors, parents should promptly take the child to a hospital for a thorough examination. In most cases, blood in a baby's stool is commonly due to poor digestion of the gastrointestinal tract or from gastroenteritis caused by viruses or bacteria due to an increase in the frequency of bowel movements, or it could be due to severe constipation in the baby, where factors like anal fissures might also lead to blood in the stool.

Is colon cancer invading the submucosa early stage?

The lesion of colon cancer has invaded the submucosa, which could be either early stage or advanced stage, as the staging of colon cancer is determined by three factors. First is the primary lesion of the colon cancer itself, second is the regional lymph node metastasis, and third is distant metastasis. The invasion of the submucosa in colon cancer is just indicative of the status of the primary lesion; we also need to consider the regional lymph nodes and distant metastasis to determine the stage. If the lesion has invaded the submucosa without regional lymph node metastasis and no distant metastasis, then its clinical stage is early. If the lesion of colon cancer has not only invaded the submucosa but also has regional lymph node metastasis or has metastasized to distant organs, then the condition would be considered as advanced stage.
