Adenocarcinoma of the intestine is a lesion of tissues of the intestinal tract organs with a malignant tumor consisting of cells of glandular epithelium.
This type of cancer is dangerous because the tumor grows slowly enough, the symptoms do not appear immediately and they are quite typical for many other less dangerous diseases and this complicates the diagnosis.
The disease can be affected by all the organs of the intestine. Metastasis usually penetrates into the nearby lymph nodes, into the lungs, into the liver. Blood carries sick cells to other tissues and organs, new, multiple tumors are formed.
Causes of adenocarcinoma of the intestine
Unfortunately, the reasons for the development of such a disease as adenocarcinoma of the intestine are huge, they are all rather banal and mostly depend on the lifestyle and preferences of the person himself.
Perhaps the most influential factor in the development of adenocarcinoma of the intestine is nutrition. Passion for fatty foods, sweets, lack of vegetables and fruits in the menu, cereals, the prevalence of meat dishes and alcohol abuse lead to dire consequences not only for the intestines, but for the entire digestive tract.
Constipation is also one of the causes of the disease, and one of the first symptoms of adenocarcinoma of the intestine, so if it appears, it is better not to engage in self-medication and immediately seek medical attention.
According to the statistics of adenocarcinoma of the intestine in most cases, people with age after 50 years, so old age can also be attributed to the causes of the disease.
Adenocarcinoma of the intestine can develop from the most common inflammations of the intestinal organs, from colitis and polyps, in case of untimely treatment. Therefore, do not even run the most innocent diseases and react to minor symptoms of their manifestations, in the future it can save your life.
And, of course, one of the most important causes of adenocarcinoma of the intestine is a genetic predisposition.
Symptoms of adenocarcinoma of the intestine
Adenocarcinoma of the intestine at the initial stages is devoid of clear symptoms, mainly they are characteristic for most diseases of the digestive system:
- stomach ache,
- lack of appetite, leading to significant weight loss,
- constipation, occasionally followed by diarrhea,
- bloating, gas,
- the appearance of bloody discharge in the feces,
- the appearance of mucous secretions and pus in the bowel movements.
Over time, all these symptoms are only aggravated, adenocarcinoma of the intestine increases and when examined it can already be detected by palpating through the abdominal wall. The growth of the tumor causes intestinal obstruction, which in turn intensifies the pain, nausea and vomiting appear.
Adenocarcinoma of the large intestine
Adenocarcinoma of the large intestine is a malignant tumor consisting of epithelial cells of the intestinal mucosa.
There are 2 types of tumors:
- Endophytic-arisen on the inner wall of the intestine
- Exophytic - arisen on the outer shell of the intestine.
Exophytic tumors are easier to feel through the abdominal wall, and endophytic developing always causes such complications as intestinal obstruction.
Adenocarcinoma of the large intestine in the initial stage is quite mobile, soft, but dense in its consistency, a tumor. Most often has a round or oval shape.

Diagnosis of intestinal adenocarcinoma
Adenocarcinoma of the intestine is a disease of elderly people, but of course there are exceptions. People after 40 years fall into the risk zone of the disease, so to prevent it you need to undergo a regular examination, and not just in case of revealing any symptoms.
To diagnose the disease, the following methods are used:
- Fecal analysis for detecting blood and examining its components;
- general blood analysis;
- Colonoscopy - examination of the intestine with the help of special equipment with a video camera;
- Ultrasound of the small pelvis, abdomen and endorectal ultrasound;
- MRI (magnetic resonance imaging) or CT (computed tomography).
Usually, several of these studies are sufficient, but to complete the picture, to better locate the tumor and to detect inflammation, it is recommended to undergo all these tests, and in the end, a biopsy should be done. Biopsy - taking a piece of tumor tissue for examination to establish the nature of the tumor, its malignancy and consistency.

Treatment of adenocarcinoma of the intestine
Adenocarcinoma of the intestine at an early stage is treatable and it is possible to achieve a lasting effect, and sometimes a complete cure.
There are several ways of treatment, but often they are used in a complex. This includes: surgery to remove the tumor and sites affected by metastases, radiation therapy and chemotherapy.
The operation on the intestine is very difficult, since with neoplasm it is necessary to be careful not to damage it so that the tumor cells with blood flow do not spread to other tissues. In addition, you need to completely remove the metastases affected by metastases.
Before the surgery, you can do irradiation, especially in the case when a large area of the intestine is affected, thanks to irradiation, a large number of malignant cells die. To use as treatment only radiation therapy is not recommended, since without surgical intervention it can not destroy absolutely all cancer cells.
In addition to the above methods of therapy is quite effective chemotherapy, but also in conjunction with the surgical removal of the tumor. Most often appointed after surgery, to consolidate the result and prevent the recurrence of the disease.

Prevention of adenocarcinoma of the intestine
Adenocarcinoma of the intestine by its nature - the body's reaction to the wrong way of life. Therefore, the best prevention will be the rejection of harmless habits: smoking, drinking alcohol, fatty foods, semi-finished products.
It is not necessary to adhere to a strict diet, but for the sake of your health you need to diversify the diet, eat more vegetable food, vegetables and fruits. Add to your menu cereal and whole cereal cereals, limit the use of meat, it is better to choose a diet that is easy to digest. With sweets you need to be careful, it's better to avoid them and replace them with cottage cheese, nuts, dried fruits. Be sure to drink plenty of fluids.
Take food 4-5 times a day, in small portions, try at the same time to develop a system, so the body will be easier to debug its work.
Prognosis of intestinal adenocarcinoma
With adenocarcinoma of the intestine, the prognosis for recovery is not very high, more often the disease does not heal completely, but thanks to therapy it recedes for a while. In general, relapses occur 3-5 years after treatment, so this period is considered critical.
Of course, the successful outcome for the patient is affected by the stage at which the intestinal adenocarcinoma was detected. If the stage is early and the entire affected tissue of the organ is removed, then according to statistics about 90 percent of such cases result in complete recovery. But unfortunately, in most cases, the diagnosis is late, when the tissues are deeply affected and there are metastases to the lymph nodes and other organs and the treatment only postpones the death for a time and slightly relieves the patient's suffering.
