Cancer: symptoms and prognosis

Cancer. Symptoms of this disease are so diverse that it is very difficult to combine them into any system.

They depend on the location of the tumor,features of the affected organ and its role in the body. Nevertheless, doctors still can diagnose cancer, the symptoms of which can sometimes be repeated in different patients. But in order to understand the appearance of what signs can indicate oncological disease, it is worthwhile to understand what exactly is called cancer. This is the popular name of a tumor that develops from epithelial tissue. It in the image often resembles a crab or a crab, that's why it got its name. Developing, the tumor can not only hit certain tissues, "sow" other cells with malignant cells, but also destroy health in general. How will the cancer determine? Symptoms (photos) can be divided into systemic, affecting the entire body, and local, destroying only the affected organs. However, it should be remembered: both those and other signs are mandatory.

Cancer. Symptoms

Local or local symptoms are those that arecan be detected visually (with or without instruments) or with palpation. What from local manifestations indicates cancer? Symptoms of obturation, in which the tumor closes the lumen in the hollow organs, compression. Sometimes education can be felt, establish the place in which it appeared, determine the boundaries of the lesion. Sometimes (for example, in cancer of the esophagus or brain), palpation is impotent. It often happens that the presence of a tumor is established too late: the cancer can first develop asymptomatically. That is why it is so important to pay attention to the primary signs that appear at the very beginning of the disease. How can you suspect cancer? Symptoms of it can be:

• Increased fatigue, progressive weakness, sometimes dizziness, convulsions, loss of consciousness.
• Increase or decrease the temperature.
• Weight loss.
• Discomfort in the affected organs.
• Violation of metabolic processes.
• Change in the condition of hair, skin, nails.

As can be seen, the symptomatology is similar to the other hundreddiseases. That is why it is important at least once a year to undergo a survey to determine the presence / absence of cancer. Today, the cancer is cured if it is discovered in time.

Stages of cancer. Symptoms and predictions

1 degree of cancer is also called damage.At this time, either the patient's DNA is irreversibly affected by external factors, or the cells mutate for some reason. At this time there is usually no pain, no unpleasant sensations, only special examinations can show the presence of the disease. 2nd stage - germination. Mutated cells begin to uncontrollably and rapidly multiply. Stage 3 - metastasis.
Affected cells begin to "sow" quicklyhealthy organs. Usually the cancer found in these stages can be cured. Stage 4 - recurrence. Cancerous tumors are formed in all "sowed" organs. There is that the uninitiated in the subtleties of medicine called metastases. If the patient turned to a doctor at this stage, then in the vast majority of cases it can not be cured.

Prevention

Prophylaxis of cancer is elementary:it is enough to consult a doctor once a year and take blood tests for cancer markers. Modern medicine is able to predict not only the presence of cancer, but also to determine how much the patient is prone to this disease.
