Neoplasms can appear on the kidneys, as well as on other organs. Benign ones differ in that they are not prone to metastasis and do not cause malfunctioning of the kidneys.
During the diagnosis, it is very important to determine the nature of the tumor in order to prescribe the appropriate treatment. One of the signs of a malignant neoplasm is a large number of vessels located next to the tumor. Such a neoplasm is called hypervascular.
Causes of appearance
The appearance of such an education is facilitated by provoking factors. The most common are:
- Weighed down heredity.
- Congenital kidney disease.
- Consequences of the infectious process.
- A large number of inflammatory diseases.
- Kidney injury.
- Bad habits.
- Hormonal disorders in women after 45 years.
If the tumor appears on the right kidney, then during growth it will transmit the inferior vena cava. In the future, this can lead to pulmonary embolism. With a mass on the left kidney, venous blood flow is disturbed.
Cancer develops under the influence of the above factors. Rebirth occurs in the epithelium. The epithelial cell takes on a different structure. After the lapse of time, it does not die off, but, on the contrary, begins to grow rapidly.
Some cells break off and join other organs with the bloodstream. They also grow on them and this is called metastasis. This process takes only a few months.
If a hypervascular formation on the kidney is diagnosed, then you should first understand the varieties in order to understand what it is.
The classification is quite large and complex. However, a more simplified version has been created.
Detonic – a unique medicine that helps fight hypertension at all stages of its development.
The complex effect of plant components of the drug Detonic on the walls of blood vessels and the autonomic nervous system contribute to a rapid decrease in blood pressure. In addition, this drug prevents the development of atherosclerosis, thanks to the unique components that are involved in the synthesis of lecithin, an amino acid that regulates cholesterol metabolism and prevents the formation of atherosclerotic plaques.
Detonic not addictive and withdrawal syndrome, since all components of the product are natural.
Detailed information about Detonic is located on the manufacturer’s page.
The most common neoplasm. At first it is asymptomatic. As the tumor grows, the corresponding symptoms appear. The initial manifestation is a slight rise in body temperature, which continues for a long time. Then other symptoms join, indicating the presence of a malignant tumor.
It is the most dangerous of the tumors. It is localized in the nephron tissue. When diagnosing, a histological examination should be carried out. It is a hypervascular formation, as it is surrounded by many vessels.
Education is life-threatening and predominantly affects the kidneys of children. If a sarcoma is found on one kidney, then soon it will appear on the other. With such a tumor, metastases quickly affect other organs. Partial organ resection helps to accelerate the growth of cancer cells. Therefore, in the presence of a sarcoma, complete removal of the organ is indicated.
While the tumor is small, it may not manifest itself. However, with its increase, symptoms may occur that indicate the malignant nature of the neoplasm:
- Weight loss with adequate nutrition.
- Intoxication, characterized by unreasonable weakness and loss of strength.
- Hematuria of unknown origin.
- Pale skin.
- Arterial hypertension.
- Swelling of the feet.
- Enlargement of lymph nodes.
- Pain in the lower back.
These symptoms are observed with a significant tumor size. The main problem is not the tumor itself, but its metastasis, which causes problems in the work of other organs.
Sometimes the tumor is disguised as other diseases. When pressure is applied to other organs, symptoms can be simulated.
It is important to know that with gross hematuria without renal colic, an examination should be carried out for malignant tumors.
Methods of diagnosis
If there are symptoms that indicate the possible presence of a malignant tumor, then you should consult a doctor. First, the doctor conducts a general examination of the patient and palpation. Sometimes a large tumor can be detected by palpation. Further, a number of instrumental and laboratory studies are carried out, which include:
Cancer treatment is a difficult task. The treatment regimen includes surgical, chemotherapy and radiological methods. Basically, surgery is performed first, and then chemotherapy is applied. Some people do X-ray irradiation despite the fact that this method has long been proven to be ineffective.
Operations are performed using minimally invasive methods: ablation and cryoablation. Before the operation, it is necessary to find out exactly how much tissue is involved in the process. Such an operation allows you to remove the tumor, but at the same time preserve all the functions of the organ. However, it is only effective in stages 1 and 2. At stages 3 and 4, complete removal of the organ is required.
Chemotherapy is quite effective, but it has many side effects. Even if the tumor stopped growing during chemotherapy, there is no need to stop, but the course must be completed.
This method uses certain drugs that affect the condition of the vessels that supply the tumor with blood. With insufficient blood supply, the tumor dies off. At the moment, this therapy is the most successful. According to statistics, people who received such therapy live longer than those who received the usual methods.
If stage 1 or 2 cancer is detected, the patient survival rate within 5 years is 90%. If stage 3 or 4 is detected, the prognosis is poor. Typically, these people die within one year of treatment.
Thus, hypervascular neoplasms on the kidneys are quite dangerous. If symptoms appear, you should consult a specialist, otherwise it will lead to death in the future.
