Colorectal cancer usually progresses for several years, and how long does it take for colorectal can

Colorectal cancer refers to rectal cancer is a relatively common malignant tumor of the digestive tract, according to its growth rate, invades the intestinal tract, generally a length of one and a half years, so colorectal cancer from early detection to advanced stage, the general decision time is about 8 months, which also depends on the patient's immune status and the pathological type of colorectal malignant tumor, such as well-differentiated and moderately differentiated adenocarcinoma, its development rate is slower, it may take longer than 18 months to reach the advanced stage, if it is a poorly differentiated cancer, In particular, mucinous adenocarcinoma and signet ring cell carcinoma have a faster development rate, which may be significantly less than 18 months in the short term.

The prevention of bowel cancer should be said from several aspects, and if it is a high-risk group, it is necessary to go to screening and examination very closely. Clause.

1. Patients who have had a history of colorectal cancer tumor surgery are still a high-risk group, and other parts may be long. Clause.

Second, people who have a history of colorectal tumors in their relatives belong to the high-risk group. Clause.

3. Patients who have had adenoma removal are recommended to go for reexamination after 1 year, as the probability of regenerating adenoma polyps is relatively high, and they also belong to the high-risk group. There is also inflammatory bowel disease, which is Crohn's disease or ulcerative colitis, which is itself a high-risk group for colorectal cancer. In addition, patients with gallbladder removal are usually high-risk groups for colorectal tumors, and should be screened more frequently than the general population.

For non-high-risk groups, it is recommended that adults over 40 years old, who have no high-risk factors and no stool changes, must have a colonoscopy screening at 5-8 years. Annual blood and stool screening, or the emerging kit screening, is acceptable. For the above high-risk groups, it is recommended to do screening once every 3-5 years, and it is recommended to do colonoscopy screening every year for patients with multiple intestinal polyp removal.

Colonoscopy is the gold standard, the most convenient, the most reliable and the most accurate, and it is a method that is difficult to replace by other examinations.

Analysis: Hello, from the patient's condition you said, it is difficult to say that it must be bowel cancer at this time, but now it depends on the patient's physical condition, but the left upper quadrant has sudden colic, so it is necessary to consider whether it is caused by volvulus.

Suggestions: At this time, it is recommended to go to the hospital for a detailed examination, and the effect will be good after finding out the condition.

Do an ultrasound and gastroscopy of the abdomen, and consider the possibility of pancreatic and stomach problems.

You need to find a professional doctor for this.

Question 1: How long does it take for bowel cancer to be in the early stage to the advanced stage Generally, it only takes a few months, and the cancer cells grow exponentially.

Question 2: How long does it take for bowel cancer to be in the early stage Once bowel cancer is diagnosed, cancer cells develop rapidly, ranging from a few months to several years.

Question 3: If it is colon cancer, how long does it take to make the transition from early to mid-stage? The stage of colon cancer is generally determined according to the depth of invasion of the primary tumor, whether there is lymph node metastasis, and which metastasis is distant to see.

Colon cancer is divided into four stages (I, II, III, IV), with stage I being early-stage cancer and stage IV being advanced metastatic cancer. It can also be divided into early, middle and late stages according to clinical symptoms.

As for the development and transition time between the periods, it is not appropriate to clearly divide and determine.

In general, for patients with histologically confirmed colon cancer, the natural course of the disease is an average of months without efficacy**, and the course of the disease can be more than 1 to 2 years in the case of a longer disease.

The progression time of each stage of colon cancer is related to the differentiation level of cancer cells, and those with low differentiation degree have a short doubling time, rapid progression and poor prognosis. In patients with a high degree of differentiation, the course of the disease progresses relatively slowly; The second is the age of onset: the malignancy of colon cancer in young patients is higher than that of middle-aged and elderly people, and the course of the disease is shorter.

Therefore, because early colon cancer is mostly asymptomatic, it is easy to misdiagnose, and due to the prolongation of the course of the disease caused by misdiagnosis, it creates time conditions for tumor growth, and most patients are diagnosed at an advanced stage.

The prognosis of this disease depends on the early diagnosis and surgery**, so if there is colon disease, or if colon cancer is suspected, it should be checked as early as possible for early diagnosis and early diagnosis**.

Question 4: How long does it take for bowel cancer to form Suggestion: Because the early symptoms of bowel cancer are not obvious, many patients who are not aware of bowel cancer find that they are already in the middle and advanced stages of bowel cancer, and the symptoms of patients are gradually highlighted at this time, and even some patients have metastasized, spread, and the cancer cells of advanced bowel cancer patients develop very quickly, so patients should actively carry out **.

Question 5: How long does it take for colon cancer to develop from early stage to middle or advanced stage According to your description, the type of cancer cell is related, some are long, some are several months, and it mainly depends on the degree of differentiation of cancer cells.

Professor Gong Yu, an expert from the First Affiliated Hospital of the PLA General Hospital (304 Hospital), said that how long colorectal cancer can live depends on many factors, and how long can you live in the advanced stage of colorectal cancer varies depending on the effect and physical function. Colorectal cancer patients should maintain an optimistic attitude, patients do not need to be affected by the question of how long can colorectal cancer live, a successful method will definitely maximize the survival period of patients.

Experts recommend DC-CIK biological immunity for colorectal cancer. The DC-CIK biological immunoassay is currently the most promising new technology for tumors.

DC cell synapses are the most powerful full-time antigen-presenting cells in the body, and they are also the only antigen-presenting cells that can activate naïve T cells, which have a unique position in the induction of immune response and are also an indispensable part of the DC-CIK biological immunity method.

It is mainly judged according to the condition and the situation, but it is also uncertain, positive and a good attitude will be of great help to the condition, or with Rh2**, it can prolong life.

All cancers are the same, they are not killed by the disease, they are scared to death by themselves! The mood is the first to open, and the good habit of paying attention to diet can be **.

Pay attention to maintenance and**, the living space is very big Don't worry, you have to combine it with the comprehensive**.

The key is the mood, and if you don't take it seriously, you might be able to live to be 100 years old.
