Colon cancer
Can advanced colorectal cancer be cured?
Complete cure is often difficult to achieve in the middle and late stages of colorectal cancer. Of course, it is possible to control the progression of the lesion and then prolong survival. For middle and late-stage colorectal cancer, if the treatment is reasonable or effective, it is possible to survive for more than three years, five years, or even longer. Clinically, surviving more than five years without recurrence is considered a clinical cure. Of course, there is still a possibility of recurrence after five years, but the probability of recurrence will be much lower. If one can survive more than ten years, or even 20 years without recurrence, it is basically considered a cure, but regular check-ups are still necessary afterward, as it cannot be guaranteed that there will be no recurrence. For the middle and late stages of colorectal cancer, surgical treatment should be pursued whenever possible, followed by a combination of chemotherapy, radiotherapy, and targeted therapy after surgery.
What are the symptoms of stool in colon cancer?
The stool of colon cancer generally appears as mucoid or purulent bloody stool, or there is alternation of diarrhea and constipation. The diagnosis of colon cancer mainly relies on electronic colonoscopy, and routine blood tests as well as carcinoembryonic antigen tests are also of certain reference value. Patients with colon cancer often present with symptoms like anemia and weight loss. Therefore, it is crucial for patients with colon cancer to obtain a definitive diagnosis as early as possible. In addition, early surgical treatment should be adopted. After surgery, adjunct treatments such as radiotherapy and chemotherapy should also be administered.
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.
Early symptoms of colon cancer
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.
