"Doctor, my mother only has a broken bone, how can it be lung cancer?”When he learned that Aunt Hou had lung cancer, his son found it difficult to accept it.
Aunt Hou, 62 years old this year, is very healthy on weekdays, and even has few colds and fevers. A few months ago, she felt that her leg was always a little dull pain, and she thought it was just caused by osteoporosis due to age, but it was not relieved for a long time, and the pain was so painful that she couldn't even walk.
One day, Aunt Hou fell while walking, and her family sent Aunt Hou to the hospital, and after the results came out, Aunt Hou was diagnosedAdvanced lung cancer, and it has metastasized to the bone, Aunt Hou's leg pain is also caused by lung cancer metastasis, such a result makes the family can't believe it, how can it become lung cancer even if it's just leg pain?
1. Why does lung cancer cause leg pain?
Lung cancer refers to malignant tumors that occur in the bronchi, trachea, and alveoliAdenocarcinoma, squamous cell carcinoma, large cell carcinoma, small cell carcinomaSeveral types. The reason why lung cancer causes leg pain is because bone metastases have occurred.
Clinically, the probability of bone metastasis in lung cancer is:Among them, the probability of bone metastasis in adenocarcinoma is the highest, followed by small cell lung cancer, squamous cell carcinoma, and metastasis of multiple lesionsRibs, thoracic spine, lumbar spine, pelvisand other parts.
Li Tao, chief physician of the Department of Bone and Soft Tissue Surgery, Cancer Hospital of the University of Chinese Academy of Sciencessaid that many cancer patients arrivedBone metastases occur in advanced stagesThere was no obvious discomfort in the early stage, but it suddenly appearedBroken bones, pain in legs and feetSymptoms, etc., have reached an advanced stage of examination. Lung cancer is one of the tumors most likely to develop bone metastases, and Aunt Hou isBone tissue is destroyed by metastatic cancer cellsThe bones become brittle, resulting in pain and fractures.
If you have 3 abnormal symptoms in your legs, beware of the signs sent by lung cancer.
Pain in both legs:After bone metastasis occurs in lung cancer, the earliest and most common symptom is bone pain, which will progressively worsen as the patient expands the lesionIntermittent pain changes to constant painIt is difficult to relieve even after resting.
Venous thrombosis of the lower extremities:The risk of venous thrombosis in cancer patients is six times higher than in the rest of the general population, and the risk of developing deep vein thrombosis in the lower extremities is higher in patients with advanced lung cancer. Once it wasDeep vein thrombosis of the lower extremitiesKeep an eye on it, and there will beAsymmetrical edema of the lower extremitiesperformance appeared.
Lower extremity edema:In patients with advanced lung cancer, due to the large consumption of protein by cancer cells, the lack of protein in the body will cause the plasma colloidal osmotic pressure to decrease, increase the permeability of blood vessels, and cause the water in the blood vessels to be transferred to the subcutaneous area, causing edema of the lower limbs, but this edema is usuallySymmetrical edema.
2. 6 symptoms in both feet may be a sign of disease
Professor Yang Li, a health expert at the China Academy of Chinese Medical SciencesIt is pointed out that the leg is the disease reflection area, and many diseases will be manifested in the legs, such as leg swelling may be caused by visceral diseases, calf cramps may be calcium deficiency, etc., once symptoms appear, they must be as soon as possible.
When the following 6 symptoms appear in both feet, beware of a sign of disease or cancer.
Swelling of the legs
Swelling in the leg caused by an injury, etc., may subside later, but be wary if you press on the swollen leg with a depression with your fingersKidney disease, heart disease, lower extremity vascular disease, metabolic diseaseetc.
Cold legs and feet
Cold legs and feet should be vigilantMetabolic dysfunction, vascular disease, nerve conduction dysfunctionDiseases such as arteriosclerosis, varicose veins, occlusion and other diseases will affect blood circulation, resulting in cold hands and feet.
Leg pain
The blood vessels of the human body will age with age, the arteries of the lower limbs are blocked, the blood is viscous, and the increase in muscle oxygen consumption when walking may lead to ischemic pain in the lower limbs.
Numbness in the legs
Leg numbness caused by sitting for a long time is ruled out, and it is necessary to be vigilantNeuropathy, arthritis, diabetes, peripheral arterial diseaseLeg numbness symptoms, etc.
Darkening of the skin tone
Darkening of the skin tone on the legs, be vigilantDiabetes, varicose veins, Raynaud's disease, metabolic diseasesand so on, which lead to vascular diseases and cause pigmentation, and it is best to investigate them in time.
