Cancer is a terrible disease. The main problem is that it is almost impossible to prevent and very difficult to detect at an early stage. The causes of oncology are for certain unknown. Among other things, very few people know the first symptoms of cancer. Therefore, people do not even know when they need to start to sound the alarm and turn to specialists for diagnostics.
Risk factors
In the course of many years of medical practice, several groups of risk were identified, that is, groups of people with a higher risk of developing oncology:
- Cancer is not transmitted "by inheritance," but those people whose relatives have had cancer should be more careful about their health.
- The first symptoms of cancer can appear in people who often come into contact with carcinogens, radiation, toxic substances.
- Smokers.
- Often the disease develops against a background of precancerous ailments: polyposis, mastopathy, cirrhosis, hepatitis.
What are the first symptoms of cancer?
- Cancer is a malignant tumor. Therefore, if you find yourself in a small knob, ulcer, birthmark, seal, lump, wound of unknown origin, it is better to see a doctor. Cancerous growths usually do not resolve for a long time and grow very slowly. An exception is only blood cancer . With this disease, tumors do not form.
- This sign of cancer, like pain, can be attributed to the first symptoms with difficulty. But sometimes it is already present at the first stage.
- Many varieties of oncology are accompanied by purulent, bloody or simply transparent pathological secretions.
- Among the first symptoms of cancer in women can be identified rapid weight loss. Of course, losing weight for a couple of kilograms does not count. With oncology for a very short period of time a patient may lose a quarter, or even half the previous body weight.
- Because of malignant neoplasms, appetite often spoils. If the organs of the gastrointestinal tract are affected, taste preferences change, and those foods that previously seemed tasty, the patient can not even take in mouth.
- Already in the first stage of cancer there is such a symptom as weakness. Of malignant neoplasm, substances that gradually poison the body are secreted into the blood. This can lead to anemia and a decline in strength afterwards.
- Deterioration of hair and skin. Because of tumors in many cancer patients, metabolic processes are disrupted.
