Data show that the incidence of colorectal cancer in China is on the rise. In 2008, there were 256,000 new cases of colorectal cancer, and it is estimated that by 2015, there will be 312,000 new cases each year. So, what are the signs of early colorectal cancer? What are the contraindications during treatment?
Because colorectal cancer is insidious and difficult to find, 80% of colorectal cancer patients are already in the middle and advanced stages when discovered, and 40%-70% of postoperative patients have tumor recurrence and metastasis. The median survival time is less than two years. These are all because people still have misunderstandings and puzzles about colorectal cancer, which has caused rectal cancer to continue to deteriorate into metastatic rectal cancer. What kind of disease is metastatic rectal cancer? What are the contraindications during treatment?
Many people don't know about metastatic rectal cancer
"A lot of people know about rectal cancer, but many people may not know what metastatic rectal cancer is." According to experts, tumor cells that occur in the colon or rectum and grow out of other parts of the body are metastatic. For rectal cancer, this spreading process is called metastasis, and the new tumor is called metastasis.
Although the tumor cells have spread to other places, the newly formed tumor is still formed by the primary tumor of the colon or rectum, so it is usually still called colorectal cancer.
Since the early symptoms of colorectal cancer are not obvious, most patients often go to the hospital several weeks or even months after the symptoms appear, missing the best time for treatment. According to clinical statistics, about 60% to more than 70% of patients are middle-advanced patients, and the true early detection rate is very low.
If you have any symptoms in your life, you should see a specialist in time
"Colorectal cancer usually starts from intestinal polyps. They are small clumps of benign cells that grow on the inner walls of the colon and rectum. After a period of time, certain polyps will become cancerous and form tumors. When the tumor cells grow to a certain extent, At times, it can penetrate the wall of the intestine and spread to adjacent parts other than the colon or rectum." Experts said that because metastatic rectal cancer is difficult to detect, it is the characteristic of late stage. Therefore, patients with uncomfortable symptoms in life, especially patients with rectal cancer or who have rectum or colon, should pay more attention.
"If the tumor invades surrounding tissues and organs, symptoms such as dysuria, frequent urination, and painful urination may occur; if the tumor invades the presacral nerve plexus, symptoms of sacral and lumbar pain will occur. When metastasized to the liver, it will cause hepatomegaly and ascites. , Jaundice, and even cachexia. Tumor enlargement can also cause intestinal stenosis and intestinal obstruction. Patients with these symptoms should seek medical treatment in time. Timely intervention is very important for cancer and other diseases. "Experts reminded that for patients with metastatic rectal cancer, there are signs to follow at the onset. In addition to common systemic symptoms such as loss of appetite, weight loss, and anemia, it is also accompanied by increased bowel movements, frequent bowel movements, and bowel movements. Endless local irritation symptoms of tumors.
"Fear of cancer" hits patient confidence, inaccurate diagnosis, delays treatment
For cancer patients, the most painful thing may not be the torture of illness, but the torture of fear. There are also uncomfortable symptoms such as hair loss, gastrointestinal discomfort, nausea, vomiting, diarrhea, loss of appetite, etc. during chemotherapy. confidence.
The same symptoms and different diagnostic options will also affect the treatment. Both rectal cancer and hemorrhoids have symptoms of blood in the stool and stool. Patients can buy medicines in pharmacies or clinics as they wish at the initial stage of symptoms. Repeated repetition will also delay the best treatment time. In the end, it is difficult to get the best treatment results in a specialist hospital.
Experts suggest that in the case of blood in the stool, long-term constipation, prolapsed material in the anus, pus in the anus, mucus in the anus, black stool, or foreign body sensation in the anus, please go to a specialist hospital for examination and be responsible for your body and your family.
Remind if symptoms such as blood in the stool should be checked in time
Colorectal cancer is a high incidence in China. In clinical work, it is often seen that patients with rectal cancer have symptoms such as blood in the stool and are misdiagnosed as hemorrhoids or diarrhea. Hemorrhoids and rectal cancer may cause similar symptoms, such as blood in the stool, difficulty in defecation, and shedding. Many people do not take it seriously. Inexperienced doctors are also lack of vigilance against rectal cancer.
Once ordinary people have symptoms such as blood in the stool, do not define hemorrhoids by themselves. They must go to the hospital as soon as possible and cooperate with the doctor to perform anal digital examination and colonoscopy, so as not to miss the best time for treatment. Generally speaking, digital anal examination can detect more than 70% of rectal cancer.
