"Doctor, I just have leg pain, how can it be lung cancer?" Mr. Li held the report and was single-hearted.
It turned out that a few months ago, Mr. Li felt uncomfortable in his legs and feet, and he had been suffering from a dull pain.
It wasn't until one time that the pain was unbearable, so he went to the hospital for an X-ray, and the results showed that he had a bone tumor in his leg, and the source of the disease turned out to be lung cancer!
The doctor explained that because of the bone metastasis of lung cancer, which caused the restriction of limb movement, it caused his leg abnormality, and reminded that the leg is closely related to human health, and it is best to pay attention to any abnormality.
1. Is the thickness of the legs related to the length of life? Research finds the answer
The authoritative journal "British Medical Journal" has released a survey data of more than 2.52 million people, and found that every 5cm increase in thigh circumference will reduce the risk of all-cause mortality by 18%. Many people only know that more fat will affect the health of the body, but in fact, different parts of the fat have different effects, and the thickness of the thighs also means that the higher the ability to store fat, which can avoid fat from running blindly to the parts that should not be destroyed.
Shanghai Jiao Tong University has also published a related study on the relationship between leg circumference and blood pressure in the journal "Endocrine Connections", through the recording and analysis of 9,520 Chinese leg circumference, blood pressure, blood data and fasting insulin and other indicators, it was found that people with thick legs will have lower blood pressure and a lower risk of heart disease.
The graph comes from the network
Not only that, the subcutaneous fat in the thighs can also promote the secretion of a variety of beneficial substances to help the body metabolize, such as promoting blood sugar metabolism and preventing the progression of diabetes.
2. If there are 5 abnormalities in the legs, beware of cancer warning signs
As the old saying goes, "The legs are the root of man, like the branches of a tree, and if the legs are sick, the whole body will be uneasy." "It reveals the reaction of the legs to health, and once there is a condition in the legs, the whole body is affected.
Indeed, 50% of the nerves, blood vessels, and blood in the human body are in the legs, which connect the body's large circulation tissues. Abnormal symptoms in both legs can often be an early sign of a condition, and many early signs of cancer can also be sent in the legs.
1. Inexplicable swelling
During the spread of cancer cells, the body's blood vessels and nerves will also be affected, and most of them are manifested as blood hypercoagulability, which slows down blood flow and may even induce blood clots.
2. The pain is unbearable
The progression of cancer cells requires the consumption of a large amount of nutrients in the body, and bone metastases may occur in addition to the primary lesion area, and once it spreads to the bones, most of the abundant blood contained in it will be diverted by the cancer cells. According to the Expert Consensus on the Clinical Diagnosis and Treatment of Bone Metastasis of Malignant Tumors, cancers prone to bone metastasis will cause severe pain after invading the legs.
3. Changes in skin color
For example, malignant melanoma will cause abnormal melanin precipitation on the patient's skin, and the skin color will deepen to gray-black and brown, and as the disease progresses, it will also lead to abnormal nodules and bulges in the affected area.
4. Appearance of lumps
It is also important to note that lumps and lumps in the legs may be caused by cancer metastases in the legs. If this phenomenon occurs, you can pay attention to the growth trend of the lump, whether the texture is soft and hard, whether the shape is clear, etc., to determine whether it is caused by the metastasis of cancer cells, and the lump caused by cancer will grow larger and larger, and the texture will be harder, and the shape of the edges will not be clear, and it will be difficult to move.
5. Abnormal bulge
If you have an unexplained bulge in your legs, you should pay attention to symptoms that may be caused by osteosarcoma.
