Even today, with the advanced development of medicine, there are still many challenges in the diagnosis and treatment of cancer. Some malignant tumors are very insidious in the early stage of onset, so that people are not easy to find, and after the tumor spreads and metastasizes, the best time for treatment is lost. In addition, the treatment of cancer is still being explored, and many cancers cannot be completely cured, but can only prolong the survival time of patients as much as possible.

Therefore, based on the current situation, it is very important for the early identification of cancer, especially in the early stage of cancer, we must attach great importance to some clues released by the body, and do not hold an indifferent attitude, which is very likely to be the key signal of diagnosis.

Generally speaking, the danger signals released by the hands and feet are the easiest for people to see, if the body has cancer, these 4 abnormal signals on the hands and feet must be highly vigilant.

1. Swelling of hands and feet

Swelling of the hands and feet is medically defined as "edema", and as the name suggests, it is the accumulation of body fluids in the interstitial spaces of the tissues, resulting in edema of the hands and feet. Generally speaking, edema occurs in the extremities, which can be divided into physiological edema and pathological edema, and physiological edema is transient and can resolve spontaneously without treatment. However, in the case of pathological edema, the edema cannot be resolved in time without human intervention.

The human circulatory system is responsible for the key to the balance of body fluids, including the liver, heart, lungs and kidneys, if these organs have malignant lesions, especially after the appearance of early tumors, it can lead to space-occupying lesions, compressing the liver and kidneys, resulting in the failure of the body's fluid circulation, and eventually may induce edema. Therefore, when there is unexplained edema in the hands and feet, it must be checked as soon as possible.

2. Abnormal nails

Many women take their nails very seriously, especially when doing nail art. However, many people may not know that nails can also reflect the health of the body, especially when you are anemic.

When the volume of peripheral red blood cells in the human body is reduced, resulting in blood oxygen can not meet the body's metabolism, it can show abnormal nail covers, generally with white cracks on the nails being the most obvious, or showing some strange-shaped nails, such as spoon-shaped nails.

If there is abnormal nails, do not take it lightly, do a test as soon as possible to determine whether there is anemia, if there is anemia, it is necessary to further look for the cause of anemia, especially anemia caused by hematologic malignant tumor lesions, and must be treated in time.

3. Change in the color of the skin of the hands and feet

Changes in the color of the skin on the hands and feet can generally be divided into two conditions. One is the appearance of an abnormal black mole on the skin, and the appearance of this mole is likely to be a malignant tumor of the skin, that is, melanoma. These moles can grow on the feet, hands, and other parts of the limbs, increasing in size for a short period of time.

The second is that the skin color will become dull, greasy, and dull, and it will also be accompanied by yellowing of the skin, which is caused by abnormal metabolism of important organs of the body, such as the liver, when the liver has a metabolic disorder of bilirubin, it can lead to a change in skin color.

No matter what the cause of the pathological skin abnormality, it is necessary to go to the hospital in time to seek medical treatment and clarify the condition as soon as possible, so as to achieve symptomatic treatment.

4. Pain in the hands and feet

There are many causes of pain in the hands and feet, such as when the blood vessels in the legs and feet are not open, the nerves are compressed, and the joints are degenerated, which can lead to leg and foot pain. However, it should be reminded that if the pain in the hands and feet is caused by aging or chronic inflammation, the course of the disease is very long, and the pain in the hands and feet will not be severe in a short period of time.

However, if there is pain and numbness in the hands and feet for a certain period of time, and the symptoms are getting worse day by day, it is necessary to pay attention to it at this time, it is likely to be caused by embolism or tumor compression, and it is necessary to do an imaging examination of the limbs as soon as possible, which can help to investigate the cause and clarify the condition.
