The scary thing about cancer is that it is difficult to control, and there is currently no effective drug that can completely eliminate cancer cells. It will continue to develop and increase in number, and ultimately shorten the lifespan of patients. Therefore, it is necessary to actively prevent and understand how cancer appears. Which characteristics are related to cancer, and early investigation can keep the disease out. So, when there is cancer in the body, does the body give the first warning?

The human body is very wonderful. Many diseases will cause damage during the development period, organ function will be reduced, and the immune system will be damaged. It will issue a warning. However, most people do not feel so obvious in the early stage when cancer threatens their health, and most of them are more sensitive. A person perceives an anomaly, although the anomaly is not very obvious. If you can go to the hospital for examination in time, it is not easy to delay treatment, but in the middle and late stages of cancer, the impact is widespread, the tumor volume increases, and the corresponding symptoms become more obvious, and the body will perceive it first.

Which features warrant suspicion of cancer?

1. Inexplicable weight loss

If there are characteristics consistent with cancer, early detection, especially weight loss in a short period of time, is likely to be a serious disease. A healthy person eats a regular diet, obtains the nutrients the human body needs in a timely manner, plus normal digestion, absorbs a lot of energy and nutrients, and the weight will be stable. In daily life, with exercise and regular work and rest to adjust, there will be no inexplicable weight loss or increase. If you lose a lot of weight in a short period of time, it may be that the cancer develops and the body's normal cells compete for nutrients.

2. Local pain

It is found that there is always pain in some parts, which is likely to be a disease signal. A healthy person is relaxed all over the body, but local cancer is developing, and the tumor volume is getting bigger and bigger, causing pressure and pulling on the surrounding tissue, and local pain may occur. People with cancerous stomach have stomach pain as the main feature, while lung cancer invades the chest, there will be pain in the chest, and after liver cancer, there will be dull pain or dull pain in the liver area. These are the signals sent by the body.

3. Abnormal bowel movements

Abnormal bowel movements, frequent diarrhea or blood in the stool, should be investigated for cancer. Because most of the blood in the stool indicates a malignant tumor of the digestive system, whether it is gastric cancer or intestinal cancer, the color of the stool may change because the tumor itself is fragile and ruptures and bleeds. Of course, the digestive system is dysfunctional during the onset, and diarrhea occurs when the digestive ability is poor. In healthy people, bowel movements are regular, and the color, state, and smell of the stool will not change.

4. Fatigue

Inexplicable fatigue, physical condition is not as good as before, and often lack of energy, all need to suspect cancer. Because cancer will affect the endocrine and immunity during the onset, even if you get more food every day and have enough rest time, you will still feel tired. The symptoms have persisted, it is best to go to the hospital for a detailed examination to clarify the cause.

5. Skin abnormalities

After the cancer strikes, the skin may look different. If there is a melanoma on the skin surface and a special black mole appears, it may be skin cancer. In addition, when lung cancer occurs, the lung function decreases during the onset period, and the breathing and circulation cannot be maintained well, and the complexion may become worse. For those with liver cancer and pancreatic cancer that threaten their health, the bilirubin level increases to a certain extent, which may lead to jaundice and chlorosis of the skin as the main feature.
