Don't easily suspect that you have intestinal cancer. Cancer is a disease that everyone is afraid of. The harm of cancer in life is enormous, so we must understand cancer, among which bowel cancer is a high-incidence cancer. Let's take a look. Don't easily suspect that you have intestinal cancer.
Don't easily suspect that you have intestinal cancer. If you suspect that you have intestinal cancer, you can go to the hospital for colonoscopy. Tumors can be found by colonoscopy. Through pathological diagnosis, it can be determined whether the tumor of intestinal cancer is benign or malignant. Pathological diagnosis is the gold standard for the diagnosis of intestinal cancer. Early detection, early diagnosis and early treatment are the keys to cure intestinal cancer and prolong life.
I always suspected that I had intestinal cancer. In this case, I must first consider whether I have symptoms of intestinal cancer. The main symptoms of intestinal cancer are abdominal pain, bloating, constipation, diarrhea and bloody stool, and bloody stool is a very typical symptom of intestinal cancer.
Early symptoms and manifestations of intestinal cancer
1, abdominal distension and abdominal pain
Many people often have these two symptoms because they are hungry and have a stomachache. They think that their stomachs are not good. They either take some stomach-invigorating and digestion-promoting tablets or take some gastrointestinal drugs, thinking that they have solved it, but it is not, or it is more serious.
In fact, the real cause of abdominal pain and bloating is the disorder of your intestinal function, and it is also because intestinal obstruction can also lead to this phenomenon. There is usually dull abdominal pain. If not treated in time, it will evolve into intestinal cancer.
2, bloody stool
Because the lesion is close to the anus, the blood color is mostly bright red or dark red, and the blood is often separated. Only when there is a lot of bleeding can you see that the stool is reddish brown and jam-like. 36% of patients with right colon cancer have this bloody stool. 5%。 This is also an early symptom of colorectal cancer.
3. Anemia
When long-term chronic blood loss exceeds the compensatory function of hematopoiesis, patients may have anemia, which is an early symptom of colorectal cancer. Tumor obstruction, when the tumor grows to a considerable volume, or infiltrates the muscle layer of intestinal wall, can cause intestinal lumen stenosis, intestinal lumen narrowing and intestinal contents obstruction.
4, stool habits and personality changes
The frequency of defecation in patients with rectal cancer can be increased, but there is not much defecation each time, or even no feces at all, only some mucus and blood are discharged, and there is a row.
5, intestinal irritation symptoms
Frequent changes in defecation habits, diarrhea or constipation, sometimes constipation and diarrhea alternate, internal urgency and then heavy, anal swelling, abdominal pain is often dull.
Don't easily doubt that you have intestinal cancer 2. Early symptoms and manifestations of intestinal cancer.
Intestinal cancer is a tumor that grows in the intestine, and the intestine is an organ that produces and excretes feces, so the earliest manifestation of intestinal cancer is stool change, as follows:
1, change of defecation habit: it is the most common manifestation. If you defecate every day 1 time, it suddenly becomes one day 1 time or several days 1 time. If the above situation lasts for a period of time, it means that there may be diseases in the intestine and you need to be vigilant;
2. Changes in the shape of the stool: Usually, the stool is strip-shaped. If intestinal cancer occurs, the tumor will compress the intestinal cavity, the stool will be flat, and even there are grooves on the strip stool, which all indicate that there may be tumors. Press the stool, the shape will change;
3. Changes in stool characteristics: stool is not strip-shaped or even shapeless, but mushy or loose stool;
4, stool color change: if the stool is yellow or yellow with green, if the stool becomes dark red, dark red or black, it means that there is a lesion in the intestine. It is recommended to go to the hospital in time.
The early symptoms of intestinal cancer are very atypical. Many patients have no symptoms, but they accidentally find intestinal masses or intestinal space occupation during examination. For example, ultrasound examination or CT examination found that there was a mass in the abdominal cavity, and further colonoscopy found that there was a tumor in the intestine, which was diagnosed as intestinal cancer by pathological examination.
In this case, if timely surgery, including timely treatment after surgery, the effect is very good. Some of the initial manifestations of intestinal cancer are abdominal pain, such as dull abdominal pain, that is, the nature of the pain is not very intense, and there is no timely treatment and no nursing.
There are also some patients with intestinal cancer, the initial performance is irregular stool, frequent stool, such as 2-3 stools a day, yellow loose stool, and may even contain a small amount of blood or a small amount of black stool.
Don't easily suspect that you have early symptoms of intestinal cancer.
1, colorectal cancer is a malignant tumor disease. Generally, patients with this disease will have obvious abdominal distension and abdominal pain. This is because there is a problem with intestinal function. If it is not well treated and controlled, the condition will become more and more serious, and patients will vomit, which is an obvious symptom of colorectal cancer.
2. Patients with colorectal cancer also have an obvious symptom, that is, bloody stool. When it is not serious, there will be bloodshot in the stool, but when the condition is serious, there will be dark red blood flowing out of the anus, which is the kind of blood secretion in the stool. The problem is very serious, which is also one of the early symptoms of colorectal cancer.
3, patients with colorectal cancer will have symptoms of dizziness and discomfort, that is, anemia. This is because it is always a symptom caused by bloody stool and long-term blood loss. Because there is a tumor in the large intestine, the intestine will narrow, and even ulcers and erosion will occur, which is also a symptom of colorectal cancer.
4, patients with colorectal cancer will have severe diarrhea, that is, the habit of defecation has changed, and the number of trips to the toilet is increasing every day, and there are not many stools, even no stools, just a little mucus, and the problem is very serious, so constipation and diarrhea are symptoms of colorectal cancer.
What are the causes of intestinal cancer?
1, dietary factors
Diet is one of the most common causes of this disease. If the patient's daily life is very irregular and he often has a full meal, it will bring great pressure to his stomach and may lead to the onset of colorectal cancer.
Moreover, a diet with high fat, high meat and low fiber is also very likely to cause colorectal cancer. High-fat food can easily lead to the increase of deoxycholic acid and lithocholic acid in gastrointestinal tract, both of which are carcinogenic.
2. Genetic factors
Cancer has obvious familial aggregation, so does intestinal cancer, so genetic factors cannot be ruled out.
Heredity is also a common inducing factor. Through the investigation, we can know that if there are patients with colorectal cancer in the family, the probability of other family members suffering from colorectal cancer will be much higher than that of ordinary people.
3. Polyps
Intestinal polyp is a common intestinal disease. When patients suffer from this disease, they must be actively treated, otherwise the disease will lead to diseases such as colorectal cancer.
4. Stimulation of chronic inflammation
The incidence of colorectal cancer in ulcerative colitis is five to ten times higher than that in normal people. Because the intestine is stimulated by chronic inflammation, it is very easy to cause colorectal cancer.
Can bowel cancer be contagious?
The onset age of colorectal cancer is mostly 40-50 years old, and the median age group is about 45 years old. People under 40 years old account for about 1/3 of all cases, and people under 30 years old account for about 10%. The onset age of colorectal cancer in China is 10- 15 years earlier than that in foreign countries, and the age under 30 accounts for 1 1%- 13%, which is a major feature of colorectal cancer in China. Like other malignant tumors, the cause of intestinal cancer is not clear, which may be related to the following factors.
1. environmental factors: among various environmental factors, diet is the most important factor, and the occurrence of intestinal cancer is positively correlated with the high intake of fat in food. In addition, it may also be related to the lack of trace elements and the change of living habits.
2. Genetic factors: "Familial colorectal cancer" has been reported at home and abroad, and the number of patients with familial colorectal cancer who died of colorectal cancer is significantly higher than that of the general population.
3, colorectal adenoma: the incidence of colorectal adenoma is quite consistent with intestinal cancer. According to statistics, the incidence of intestinal cancer in patients with 1 adenoma is five times higher than that in patients without adenoma, and that in patients with multiple adenomas is 1 times higher than that in patients with single adenoma.
4. Chronic inflammation of large intestine: The prevalence of intestinal cancer is positively correlated with schistosomiasis endemic areas. It is generally believed that due to schistosomiasis, inflammatory changes will occur in the intestine, and some will become cancerous. Other chronic inflammations in the intestine are also likely to become cancerous, such as ulcerative colitis, with 3%-5% canceration.
For the treatment of intestinal cancer, we need to know more about the common sense of intestinal cancer, so that we can know the cause of intestinal cancer. In order to treat intestinal cancer better, we need to know more about the early symptoms of intestinal cancer and try to find the disease as soon as possible. So what are the early symptoms of intestinal cancer?
Main symptoms: change of defecation habits, bloody stool. More often, the frequency of defecation increases, the stool is not shaped or loose, and there may be mild abdominal pain before defecation; Blood in the stool is an important symptom, which is manifested by the discharge of bright red or dark red feces, often accompanied by mucus.
Abdominal pain is also an early symptom. The pain is mostly in the middle and lower abdomen, and the degree is not heavy. Most of them are dull and neglected. Abdominal distension, abdominal mass, anemia and intestinal obstruction are the late symptoms of intestinal cancer.
To sum up, I believe that everyone should be able to understand the answer to whether intestinal cancer will be contagious.
Everyone must pay attention to the early symptoms of intestinal cancer. Once discovered, you must not take any chances. Be sure to go to a regular hospital for relevant examinations to avoid the occurrence or deterioration of intestinal cancer.
How to treat intestinal cancer?
1, surgical treatment
The treatment of colon cancer is a comprehensive treatment based on surgical resection. Radical resection and regional lymph node dissection are often used in patients with stage ⅰ, ⅱ and ⅲ, and the scope of radical resection and its surgical method are determined according to the location of cancer.
If stage ⅳ patients have intestinal obstruction and severe intestinal bleeding, radical surgery is not needed for the time being, and palliative resection is feasible, which can relieve symptoms and improve the quality of life of patients.
Surgery is the basis of radical resection of rectal cancer. Rectal surgery is more difficult than colon surgery. The common surgical methods are: transanal resection (very early near anal margin), total mesorectal resection, low anterior resection, transanal sphincter combined with abdominoperineal resection.
For stage ⅱ and ⅲ rectal cancer, preoperative radiotherapy and chemotherapy are recommended to reduce the tumor and local tumor stage, and then radical surgery is performed.
2. Comprehensive management
Oxaliplatin combined with fluorouracil (5- fluorouracil) as adjuvant chemotherapy is the standard treatment scheme for patients with stage ⅲ colorectal cancer and some patients with high risk factors, and the treatment time is 6 months.
It is suitable for rectal cancer patients who have not received neoadjuvant radiotherapy before operation and need adjuvant radiotherapy after operation.
The treatment of colorectal cancer is mainly a comprehensive treatment scheme based on chemotherapy. Chemotherapeutic drugs include 5- fluorouracil, capecitabine, oxaliplatin, irinotecan, bevacizumab, cetuximab, panizumab and other drugs. Commonly used chemotherapy schemes include FOLFOX, XELOX, FOLFIRI, etc. On the basis of chemotherapy, targeted drug therapy (bevacizumab and cetuximab) should be combined as appropriate.
3. Radiotherapy
At present, the comprehensive treatment of surgery and radiotherapy, including preoperative radiotherapy, intraoperative radiotherapy, postoperative radiotherapy and "sandwich" radiotherapy, has its own characteristics.
Palliative radiotherapy is suitable for patients with advanced rectal cancer, patients with local tumor infiltration and patients with surgical contraindications to relieve symptoms and pain.
