What are the symptoms and diagnosis of prostate cancer? Introducing relevant knowledge about prostate cancer

The male prostate is a site that is very prone to lesions. Common diseases include prostatitis and prostate cancer. Prostate cancer is a malignant tumor that occurs in the epithelial tissue of the male prostate. There are many types of prostate cancer, mainly adenocarcinoma (acinar adenocarcinoma), ductal adenocarcinoma, urothelial carcinoma, etc. The vast majority of prostate cancers are adenocarcinomas. What we usually call prostate cancer generally refers to adenocarcinoma. Prostate cancer often occurs in middle-aged and elderly people. So, what are the symptoms and diagnosis of prostate cancer? Let us introduce the relevant knowledge below.

Clinical symptoms of prostate cancer. There are two types of prostate cancer clinically, including compression symptoms and metastasis symptoms. The compression symptoms of prostate cancer are mainly manifested as difficulty urinating, thin urine stream, short range, incomplete urination, labored urination, etc. Severe patients may also have urinary incontinence. As the tumor continues to grow, the rectum will be compressed, leading to difficulty defecation or intestinal obstruction. The tumor will also compress the nerves, causing nerve pain. Prostate cancer is a malignant tumor that is prone to metastasis. Cancer cells can easily metastasize to the bladder, seminal vesicles, vascular nerve bundles and other parts, leading to hematuria and hematospermia.

Diagnosis of prostate cancer. The diagnosis of prostate cancer requires a series of examinations, including rectal examination, serum pSA, pelvic MRI examination, etc. Although CT can diagnose early prostate cancer, its sensitivity is not high. Because prostate cancer is very easy to metastasize, a radionuclide bone scan must be performed before treatment to decide whether to perform surgery. A puncture biopsy of the prostate can confirm prostate cancer.

This article introduces the symptoms and diagnostic requirements of prostate cancer. Prostate cancer is a male cancer with a high incidence rate, and often occurs in men with a family history of the disease. Therefore, people with a family history of the disease should go to the hospital for regular physical examinations to detect cancer in a timely manner. Once prostate cancer is diagnosed, it must be treated in a timely manner to avoid delaying the best treatment opportunity.
