What are the early examinations of prostate cancer? What is the gold standard for diagnosis of prostate cancer
Cancer is something that every friend doesn't realize, but in real life, many friends are still threatened by cancer. For men, especially middle-aged and elderly male friends, they are vulnerable to prostate cancer, so they want to share common knowledge about disease.
Early detection of prostate cancer is very important
It is said that cancer is an incurable disease, but it can also be treated now. But because cancer is benign, as long as it is detected that it does not need more treatment, and it is found that it is malignant, the examination is more important, so the early examination of prostate cancer is the most important.
The early examination of prostate cancer is very important. The early symptoms are not obvious and are easily confused with other prostate diseases. When the prostate is invaded, symptoms similar to benign prostatic hypertrophy appear, such as frequent urination, nocturnal urination, acute urination, small urine flow, urethral pain, hematuria and other symptoms. When the prostate is transferred to bone, lumbago and neuralgia such as lumbar bone and nerve pain occur. However, in recent years, due to medical advances, if early diagnosis and treatment can be made, The 5-year survival rate of prostate cancer is still about 70%.
Clinical observation shows that more than half of the patients will have cancer metastasis within one year after their symptoms appear. Therefore, we should fully understand the various symptoms of prostate cancer, early detection and early treatment.
Pay attention to the inspection results
Some patients with early prostate cancer often have poor urination and frequent nocturnal urination. The examination report shows that the PSA value is high. However, many middle-aged and elderly patients do not care about this. They often attribute urination symptoms or PSA elevation to prostatitis or benign prostatic hyperplasia, and are unwilling to accept the routine examination of prostate cancer. After a large amount of prostatitis is ineffective, the psychological pressure of patients is increasing.
In fact, such patients ignore the usual examination with a sense of luck. Generally speaking, according to the routine diagnosis and treatment of prostate cancer, if the PSA continues to be on the high side, the digital examination of the anus finds abnormalities, or the ultrasound, CT and other image examinations find prostate masses, it is recommended to conduct prostate puncture biopsy again. This is because only according to the pathology of biopsy can we judge whether it is cancer. It can be seen that if the early patients can reverse their thinking as soon as possible and accept the systematic examination according to the doctor's advice, they can find the tumor and carry out radical surgery as soon as possible.
What should be paid attention to in the diagnosis of prostate cancer
Prostate cancer is a very dangerous disease. Because patients with this disease must be diagnosed immediately, so patients should be diagnosed. The diagnosis of prostate cancer needs attention. Because the patient has metastasis.
1. Lymphatic metastasis. Prostate cancer is prone to lymphatic metastasis, so attention should be paid to the diagnosis. The obturator - internal iliac chain is the first lymph node invaded by prostate cancer. In fact, the obturator lymph nodes are generally not invaded. Clinically, the internal iliac lymph nodes are often called obturator lymph nodes, which are located inside the external iliac vein and walk along the internal iliac vessels. The most important thing is to remove the lymph nodes. The diagnosis of lymph node metastasis relies on CT and MR in recent years, but it is impossible to detect small lesions by lymphography. It can detect 70%~90% of the metastasis, but the false negative and false positive are high. In recent years, the most valuable diagnostic improvement of lymph node dissection is to remove the lymph nodes between the internal and external vessels and obturator. As a correct stage, it can avoid complications such as lower limb swelling of lymph nodes after the removal of lymph nodes in front of the pelvic wall of the vessel obturator in the past
2. Primary tumor. There are many methods for the diagnosis of primary tumors, including digital rectal examination. The prostate nodules found by rectal digital examination can be examined by tru-cut biopsy or transrectal franzen fine needle aspiration cytology. Transrectal prostate ultrasound scanning can understand the size and scope of the tumor. The boundary of normal prostate echo is not clear when it evenly invades the capsule. Echo changes can also be caused by inflammation and stones. CT magnetic resonance (MR) should be differentiated to understand the scope of tumor and the pathological changes of bladder seminal vesicle lymph nodes.
Cancer prevention is something that every friend needs to pay attention to, especially some common diseases with high incidence in our own population. We need to learn some preventive measures. Do you remember the common sense of prostate cancer?
