short paragraph, a 19-year-old freshman who usually likes to play basketball. He is sunny and full of positive energy all day long. But just in the past few months, my left calf suddenly cramped during activity. I thought it was caused by excessive exercise, so I didn't pay attention.

It wasn’t until recently that I had frequent twitchings, which were more obvious at night, and even accompanied by knee joint pain, , limited movement, and a small lump in the local area, which seemed to be getting more and more serious, that I informed my parents.

The family was so anxious that they came to the hospital for a checkup. After examination, they found a tumor on 's left thigh near the knee. After 's pathological examination, determined it to be osteosarcoma .

With the help of an orthopedic surgeon, the osteosarcoma was successfully removed and part of the bone graft was performed. Due to poor postoperative function, he is currently undergoing rehabilitation treatment.

The whole family is confused. Is there a cancerous tumor at such a young age? Or is it growing on the legs? I have basically never heard of it; in fact, tumors can occur anywhere in the body, possibly in the legs, and they are ignored by everyone when they send out some "signal signals".

Today, Dr. Kong will talk to you about what symptoms appear on the legs that require everyone to be highly vigilant. It may be an early warning of cancer !

1. There are lumps on the legs

There are many muscles attached to our thighs and calves. If there is a lump, we must pay close attention to it. It may be sarcoma , or it may be chondroma , etc.

Whether it is benign tumors or malignant tumors, they are more common in the legs during adolescence. Most of them occur in the metaphysis of long bones, that is, near the joints, such as the distal end of the thigh and the proximal end of the calf.

When a mass appears, you can touch it with your hands. If it has unclear boundaries, is infiltrated and adhered to the surrounding tissue, has a high temperature on the skin surface, and has obvious tenderness and swelling, it is highly suspected that it may be a malignant tumor . On the contrary, it may be a benign lump.

2. Frequent leg cramps at night

In our daily life and work, we always think that leg cramps are a trivial matter and do not take it seriously. Of course, many friends who have experienced this have reported that nighttime leg cramps are too painful, but they don’t know what causes them?

Generally, leg cramps occur at night, mostly seen in the following 3 situations :

① Middle-aged and elderly people are likely to have declining body functions with age, endocrine dysfunction, abnormal hormone regulation of levels, especially a decrease in blood calcium concentration , it is very easy to cause leg cramps.

② There are also leg cramps, which may be due to excessive exercise during the day, standing or walking for a long time, and muscle fatigue spasms; or at night, the temperature is relatively cold, and the legs are not kept warm, resulting in blood vessels in the cold environment. Spasm , thus stimulating the body's metabolites to accumulate in the leg muscles, causing cramps.

③ Some people with diabetes or lower limb arterial occlusion have hardened plaques in the blood vessels in their legs, which blocks the blood flow and causes muscle ischemia, spasm and shaking.

Of course, in addition to the above two situations, there is also a special kind of frequent leg cramps at night , which is difficult to relieve no matter what method, needs to be paid great attention to, it may be caused by cancer ; most common in liver cancer , lung cancer, thyroid cancer , or cancer metastasis.

3. Severe leg pain at night

Common leg pain has known causes, such as muscle strain , degenerative joint disease, leg venous thrombosis, etc.; these leg pains have clear causes. Local pain is generally not persistent pain, but is characterized by intermittent pain.

If your leg pain is severe, especially when it is more obvious at night, and occurs repeatedly and continuously, which completely affects the entire person's sleep quality, you need to pay close attention to it, as it may be an early warning of cancer.

At this time, you need to observe your recent physical changes. For example, in your daily life, Has your appetite decreased? Have you experienced any unexplained weight loss? Do you experience frequent dry coughs at night?

Because the above symptoms appear, most of them are related to cancer, such as the most common lung cancer, liver cancer, stomach cancer , blood cancer, prostate cancer ; they may be primary cancer causing severe pain in the legs at night, It is also possible that symptoms in the legs may be caused secondary to metastasis of these cancers.

4. Inexplicable weakness in the legs

Weakness in the legs is relatively common among the elderly. No need to make a fuss about it. It may be caused by lumbar diseases, such as intervertebral disc herniation, lumbar spinal canal stenosis, or the elderly who sit for a long time and do not like to exercise.

If 's legs become progressively weaker in a short period of time without trauma, we should also pay attention to whether the central brain tumor may be compressing the nerves?

What happened to me was a relative of mine who was in his 50s and had been doing hard labor outside for many years. Suddenly he felt pain and discomfort in his waist, so he went to the local clinic for infusion and injection. He thought it was lumbar disc herniation , the results get worse the more treatment is given.

later consulted me. After hearing the introduction, the situation was not good, so he was sent to a public tertiary hospital for examination. He was diagnosed with lung cancer causing bone metastasis in the waist. Within a few days, he suddenly became weak in his legs and eventually became paralyzed. He underwent brain surgery again. CT examination showed brain tumor metastasis.

Summary

The above symptoms in the legs are common situations we encounter in daily life. Most of them may be caused by certain diseases, but special situations cannot be ignored. It is recommended that everyone be cautious and seek medical treatment as soon as possible when there are problems. Check .

Therefore, for the sake of your own health, you must change the factors that you can intervene in, such as bad living habits, strengthen your own exercise, and conduct regular physical examinations on your body.
