Feet are early warning signs of cancer? Inventory of 4 kinds of leg abnormalities may be a harbinger of a certain disease

The 66-year-old Li Bo has always had soreness in his lower back and legs since he retired from work. He originally thought it was just osteoporosis due to age, but unexpectedly, it became more and more serious.

A few days ago, I accidentally twisted my left leg, and I didn't expect it to be broken. The family hurriedly carried him to the hospital for an examination, and the results of the examination shocked the whole family. The doctor diagnosed as malignant tumor lesions and pathological fracture of left femur, which was caused by bone metastasis of lung cancer.

The symptoms of lung cancer in the early stage are not obvious. Like Sun Bo, many people wait until the leg pain and bone metastases are transferred to the hospital. At this time, the disease is already in the advanced stage, and the treatment is difficult and the prognosis is poor.

In daily life, don't always treat leg pain as a minor illness. In fact, many diseases and even cancer can manifest in the legs, so we should not be careless.

1. Legs respond to systemic diseases, legs are the second heart of the human body

Chai Shengting, deputy director of the Joint Orthopedics Department of the Third Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine, said that from the perspective of modern medicine - the leg is the "second heart" of the human body. This is because of the effect of gravity. After the blood flows to the legs, there will be a certain resistance to the return of the heart to the heart. The blood is pushed back into the heart only by the pressure generated by the contraction of the leg muscles.

Half of the blood, nerves and blood vessels of the human body are distributed in the legs, and there are more than 60 acupuncture points. Many important meridians such as the three yin meridians of the foot and the three yang meridians of the foot also pass through the legs. It can be said that the legs are the "important traffic artery" for the blood circulation in the body, and play a linking role in the blood circulation of the whole body. Many diseases can also be reflected by abnormal appearance of the legs.

Abnormalities in the legs can help people find abnormalities in time, which is of great significance for the prevention and treatment of early diseases. Be vigilant when you notice these symptoms in your legs.

2. These abnormalities in the legs may be a sign of disease or cancer

1. Persistent low back pain

Bone, lung, and liver are the three major metastatic sites of tumors. Breast cancer, prostate cancer, thyroid cancer, lung cancer, and kidney cancer have a risk of bone metastasis of 73%, 68%, 42%, 36%, and 35%, respectively. 70% occur in the spine. Cancerous neck and shoulder pain and low back and leg pain are characterized by persistent and persistent pain, especially at night. When you find bone pain in your body with these characteristics, you must seek medical attention in time.

2. Inexplicable long lumps in the legs

Under normal circumstances, the skin of our legs should be smooth and delicate. If you find abnormal lumps, you need to be alert.

Osteosarcoma is often manifested as an abnormally raised mass in the leg. It occurs in adolescents. The mass is firm and the superficial veins are exposed. There may be varying degrees of tenderness on the surface of the mass and the surrounding soft tissues. As the mass becomes larger, it can also affect joint activities. And muscle atrophy, in addition, there may be pain in the legs, which is easy to be confused with growing pains.

3. Inexplicable swelling

When cancer cells are rampant in the body, they will also affect the blood vessels and nerves in the legs, causing abnormal edema and pain in the legs of patients. Clinically, some cancer patients are treated with swelling and pain in the legs as the first symptoms.

It's worth reminding that not all abnormal leg swellings are caused by cancer. Deep vein thrombosis of the lower extremities and severe cardiac insufficiency may also affect the blood circulation of the lower extremities, leading to edema.

4. Abnormal color

In most cases, there will be no noticeable abnormal color changes in the skin of the legs. If you find that the skin color of the legs gradually darkens, you need to be alert to metabolic abnormalities that may be caused by the invasion of cancer cells.

For example, malignant melanoma can cause abnormal melanin precipitation on the skin of patients. As the disease progresses, the lesion area will gradually increase, and the affected area will appear bulging, plaques, and nodules. In addition to melanoma, squamous cell carcinoma of the skin can also cause abnormal skin color in patients, accompanied by a distinct foul odor.

Abnormal manifestations in the legs are not necessarily the manifestations of disease or cancer, and some physiological reasons may also cause them. If the abnormality persists for a long time or seriously affects your life, you must seek medical attention in time. In addition, it is also recommended that you exercise your legs more in your life, or you can reduce the risk of death to a certain extent.

3. Strong legs can lead to longevity, I hope you practice more legs

According to the "Report on Travel and Foot Health of the Elderly in my country", nearly 90% of the elderly in China suffer from different degrees of leg disease. The vast majority of the elderly therefore endanger their daily travel and physical health. To maintain longevity, maintaining leg health is particularly critical.

With the increase of age, the skeletal muscle mass of the lower limbs of the elderly will gradually decrease, and the motor function will also gradually decline. If it continues to develop, it may cause the elderly to have difficulty standing, balance disorders, falls and other symptoms, which seriously threaten the quality of life of the elderly.

A study published in the British Medical Journal analyzed the health data of about 2.52 million people and concluded that every 5cm increase in thigh circumference was associated with an 18% lower risk of all-cause mortality.

Leg strength is so critical to health. As ordinary people, how should we exercise? These four workouts work well.

Fourth, how to exercise the legs, make the legs more powerful?

Before exercising, you must choose the appropriate intensity according to your physical fitness, and exercise with safety as the first principle. Some people who have a very serious decline in their leg strength must not force themselves to exercise overloaded, and can choose some more soothing ways of exercise.

1. Ballet circle

The ballet circle can exercise the iliopsoas, gluteus medius, gluteus maximus, quadriceps femoris and triceps calf. When exercising, you need to stand upright, and then use your left and right feet to draw circles. Some elderly people with poor balance can choose to hold the object next to them with one hand to maintain balance.

2. tiptoe

Take a standing position and place your hands vertically at your sides, with your legs knee-width apart. Then slowly lift the heel about 5cm, feel the calf muscle contraction and tension, and then slowly lower back to the starting position.

3. Squat

Separate your legs and hip-width apart. It is recommended to lift a certain weight such as mineral water or dumbbells in your hands, and then squat down with your elbows down and knees bent. Pay attention to keep the abdomen closed when squatting, the knees should not exceed the toes, and avoid using the waist and knees to compensate for the exercise.

4. Glute bridge

Take a supine position and lie flat on the yoga mat. When exhaling, lift the pelvis until the upper body and thighs are close to a straight line. During this process, pay attention to tightening the abdomen and back. When inhaling, gradually relax the buttocks muscles and slowly lower them. Repeat the exercise.

The health of the legs is very important to our health. We should pay more attention to the legs in daily life, and seek medical attention in time if any abnormality is found. At the same time, in life, you also need to pay attention to exercising your leg muscles to keep them strong, which also has a certain positive significance for health.
