Body cancer, foot prophet? 4 'abnormalities' in the legs, or signs of cancer
Leg pain, could it be lung cancer?
The 66-year-old Sun Bo has always had soreness in his lower back and legs since he retired from work. He 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.
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, which is more common 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 nearby 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.
