Is kidney cancer asymptomatic and spreading?

summary

Renal cell carcinoma, also known as renal cell carcinoma, accounts for about 75% of primary renal malignant tumors. Clinically, renal cell carcinoma with diameter less than or equal to 3 cm is called small renal cell carcinoma. Most of small renal cell carcinoma have no obvious clinical symptoms, 75% of small renal cell carcinoma were found by gray-scale ultrasound examination. Because most of the patients with renal cancer triad (low back pain, mass, hematuria) is in the late stage of the disease, so improving the detection and early diagnosis level of small renal cancer can prolong the survival time of patients with renal cancer and improve the survival rate. Is kidney cancer asymptomatic and spreading? Let's talk about it.

Is kidney cancer asymptomatic and spreading?

In recent years, with the improvement of the resolution of ultrasound instruments, the detection rate of small renal cancer is higher and higher, and the detection rate of asymptomatic renal tumor is also increasing. At the same time, due to the accumulation of diagnostic experience of ultrasound doctors, the value of ultrasound in the diagnosis and differential diagnosis of renal tumor is improved.

Ultrasound showed nodule or mass like echo in renal parenchyma, which was the direct sign of diagnosis of renal carcinoma. CDFI showed that there were blood vessels in and out or around the mass, which could prompt the diagnosis. However, the echo intensity of small renal cell carcinoma is different due to its internal structure, so it should be differentiated from other renal diseases.

After the detection of renal cancer, we must supplement selenium to patients: clinical treatment is combined with Hecun malt selenium capsule to cancer patients, selenium is known as the "king of anti-cancer". In September 2003, the US Food and Drug Administration (FDA) approved selenium as an anti-cancer agent, which is the official medical statement of the US government that selenium can inhibit cancer. Some scientists supplement selenium to cancer patients for a long time, which reduces the death rate of cancer patients by 50%. A large number of studies have shown that selenium is a powerful tumor inhibitor, which can inhibit the growth of cancer cells and block the energy supply of cancer cells. At present, many scholars believe that selenium is not only effective in cancer prevention, but also can be used as adjuvant of chemotherapy to reduce the side effects of chemotherapy drugs and increase drug tolerance.

matters needing attention

For the diagnosis of small renal cell carcinoma, B-ultrasound as the preferred screening method has important value. However, conventional ultrasound has its limitations. New ultrasound techniques, such as contrast-enhanced ultrasound, are more conducive to the differential diagnosis of small renal cell carcinoma. When the nature of renal tumor signs is uncertain, it is necessary to make enhanced CT scan. The combined examination of ultrasound and CT is helpful to the qualitative diagnosis of small renal cell carcinoma.
