There are a few points to note when diagnosing prostate cancer

It is necessary for men to understand the diagnosis methods of prostate cancer. This is good for men. Everyone needs to know more about the diagnosis methods of prostate cancer. Now, let the experts discuss with you what are the diagnosis methods of prostate cancer. I hope it can help everyone better understand the diagnosis methods of prostate cancer .

1. Lymph node metastasis: The first lymph nodes invaded by prostate cancer are the obturator-internal iliac chain. In fact, the lymph nodes at the obturator foramen are generally not invaded. Clinically, the internal iliac lymph nodes are often called obturator lymph nodes. They are located on the inner side of the external iliac vein and run along the internal iliac blood vessels. They are the most important lymph nodes that should be removed. This is one of the diagnostic methods for prostate cancer.

The diagnosis of lymph node metastasis has relied on CT and MR in recent years, but they cannot detect small lesions. Lymph node angiography can detect 70% to 90% of metastases, but the false negative and false positive rates are high. In recent years, the most valuable diagnostic modified lymph node dissection has been less used, that is, removing the lymph nodes between the internal and external iliac vessels and the obturator foramen. It is more accurate for staging and can avoid complications such as lymph leakage, lymphatic swelling, and lower limb swelling caused by the previous removal of the iliac vessels, obturator foramen, pelvic wall, and anterior iliac lymph nodes, because even extensive dissection cannot prevent existing metastasis.

2. Primary tumors Prostate nodules can be found by rectal digital examination through tru-cut biopsy or transrectal franzen fine needle aspiration cytology. Transrectal prostate ultrasound scan can understand the size and range of the tumor. Normal prostate echoes are not clear when they invade the capsule evenly. Echo changes can also be caused by inflammation and stones, which should be identified. CT magnetic resonance imaging (MR) can also understand the scope of tumor lesions and lesions of bladder and seminal vesicle lymph nodes, which is also a diagnostic method for prostate cancer.

3. Diagnosis of distant metastasis of prostate cancer: When ureteral obstruction is found during intravenous urography, it means that the tumor has invaded the seminal vesicle, bladder neck and lymph nodes, and may have distant metastasis.

Through the above introduction, everyone should have some understanding of the diagnosis method of prostate cancer. I hope it can bring some help to everyone. I wish that patients can choose the treatment method that suits them as soon as possible and recover soon.
