I don't know if you have watched the recent TV series ---- "Little Min's House"?
To be honest, Dr. Xiaokang, like everyone else, wants to send blades to the screenwriters.
Originally could have had a happy ending, the screenwriter had to have the whole dog blood, Chen Zhuo such a good person, but was found to have kidney cancer, even the crazy Xu Zheng was also whitewashed, is the first bitter drama in 2022 going to be staged?
Kidney cancer, what kind of cancer is it?
After repeated physical examinations, Chen Zhuo was diagnosed with kidney cancer in the middle stage, and the local spread began to spread, requiring chemotherapy and surgery.
In China, kidney cancer is the second tumor in the urinary system, second only to bladder tumors, accounting for 3% to 4% of adult malignant tumors and 20% to 25% of pediatric malignant tumors.
The disease is on the rise year by year, mostly in middle-aged and elderly men aged 50 to 70 years old, mainly related to smoking, alcohol consumption, drug abuse, genetics and other factors.
For Chen Zhuo of the TV series who has kidney cancer, there are actually two clinical manifestations that can be mentioned, one is: more than 70% of kidney cancer patients have no symptoms in the early stage; second, the study found that obese people are more likely to develop kidney cancer.
Obviously, Chen Zhuo's sudden kidney cancer is also reasonable.
Kidney cancer, which early symptoms are the most obvious
Patients with early kidney cancer will have symptoms of hematuria, which is mostly intermittent, mainly related to tumor invasion of the renal pelvis or renal calyx mucosa.
Patients may also have streaks of blood clots, and as the course of the disease is prolonged, the intermittent period of hematuria will shorten, and even persistent hematuria will appear.
General hematuria is pink or dark red, visible to the naked eye, and erythrocytosis is also shown on routine urinalysis tests.
In addition to symptoms of hematuria, patients also have symptoms such as lumps, low back pain, and hypertension
Lumps appear in only a few patients, and patients with long bodies are more likely to appear. The mass is mostly located under the ribs of the upper abdomen and can move up and down with respiratory movements.
If the mass is immobilized, the tumor has invaded other organ structures around the kidney.
Most of the low back pain is dull or hidden pain, usually due to tumor growth involving the renal envelope or invading the adjacent organs of the psoas major muscle.
This type of low back pain is characterized by a sudden onset of severe pain that can start in the lower back of the affected side and radiate down the ureter to the lower abdomen, groin, and inner thigh, and hypertension is caused by excessive renin production by the tumor.
The above is the signal symptoms that kidney cancer patients may urinate, and if this signal symptom is found, the patient should go to the relevant examination in time.
What are the methods of kidney cancer screening?
1. Ultrasound
Ultrasound is the easiest and more commonly used method to find the disease, through this method to help identify the benign and malignant nature of kidney tumors, find small mass lesions in the kidneys, and the lesions can be accurate to more than one centimeter, which is easy to distinguish from other kidney diseases.
2. CT of the abdomen
A commonly used test for the disease is abdominal enhancement CT, which is valuable for the diagnosis of the disease, can find smaller lesions and accurately stage them.
At the same time, it can also distinguish other renal parenchymal diseases, such as renal cysts. In addition, CT-enhanced angiography and three-dimensional reconstruction can replace the traditional simple renal angiography to find multi-vascular mass lesions and tumor blood vessels.
3. Urinalysis
In this disease, about 40% to 60% of patients develop hematuria. Therefore, through the urine routine examination, it is possible to find out whether red blood cells are present in the patient's urine to diagnose the disease.
In addition, doctors can also use urine cytology to determine whether there are cancer cells in the urine.
In general, once suffering from kidney cancer, patients may urinate with blood, causing hematuria.
When such hematuria symptoms are found, the patient should be highly vigilant and promptly undergo a renal examination. After checking, the patient should be treated according to the stage of the tumor, surgery, drugs and so on.
In general, in patients with different stages, the prognosis often varies greatly, of which the prognosis is poor in the late stage, but after systematic and standardized treatment, it can also alleviate the symptoms and pain of advanced patients and improve the quality of life.
In the early stages, after timely and systematic treatment, some can even be cured, and the postoperative survival rate can reach 97%.
