Cancer. The 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, the characteristics of the affected organ and its role in the body. However, doctors can still diagnose cancer, the symptoms of which can sometimes recur in different patients. But in order to understand what signs may indicate an oncological disease, it is worth understanding what exactly is called cancer. This is the popular name for a tumor that develops from epithelial tissue. It often resembles a crayfish or a crab in its image, which is why it got its name. Developing, a tumor can not only affect certain tissues, “seed” other organs with malignant cells, but also destroy he alth in general. How is cancer diagnosed? Symptoms (photo) 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 appear necessarily.
Cancer. Symptoms
Local or local symptoms are those that can be detected visually (with and without instruments) or bypalpation. What of the local manifestations indicates cancer? Symptoms of obturation, in which the tumor closes the lumen in the hollow organs, compression. Sometimes the formation can be felt, to establish the place in which it appeared, to determine the boundaries of the lesion. Sometimes (for example, with cancer of the esophagus or brain), palpation is powerless. It often happens that the presence of a tumor is established too late: cancer may initially 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 cancer be suspected? Its symptoms may be:
- Fatigue, progressive weakness, sometimes dizziness, convulsions, loss of consciousness.
- Increase or decrease the temperature.
- Weight loss.
- Discomfort in affected organs.
- Violation of metabolic processes.
- Change in the condition of hair, skin, nails.
As you can see, the symptoms are similar to a hundred other diseases. That is why it is important to undergo an examination at least once a year in order to establish the presence / absence of oncological disease. Today, cancer is curable if it is detected in time.
Stages of cancer. Symptoms and prognosis
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 or discomfort; only special examinations can show the presence of the disease. Stage 2 - germination. Mutatedcells begin to multiply uncontrollably and rapidly. Stage 3 - metastasis. Affected cells begin to quickly "seed" he althy organs. Usually cancer found in these stages can be cured. Stage 4 - recurrence. Cancer tumors are formed in all "seeded" organs. There is what the uninitiated in the subtleties of medicine call metastases. If the patient went to the doctor at this stage, then in the vast majority of cases it is impossible to cure him.
Prevention
Prevention of cancer is elementary: it is enough to visit a doctor once a year and take blood tests for tumor markers. Modern medicine is able to predict not only the presence of cancer, but also to determine how prone a patient is to this disease.
