What are the types of prostate cancer?

I believe that most male friends are familiar with prostate cancer. This is a common cancer disease that has a great impact on men's health. In addition, there are many classifications of this disease. When treating it, it is necessary to identify the type of prostate cancer before treatment. So what are the types of prostate cancer?

1. Latent prostate cancer: refers to adenocarcinoma originating from the prostate that is found by pathological examination during postmortem examination in the absence of symptoms and signs of prostate disease during life. Latent cancer can occur in any part of the prostate, but is more common in the central and peripheral areas, and is often a well-differentiated adenocarcinoma. Its incidence rate is reported to be 15% to 50% abroad. A study by the Urology Research Institute of Peking University Medical School in my country reported that the incidence rate of latent prostate cancer is 34%. Statistical studies have shown that the incidence of latent prostate cancer may be related to environmental and genetic factors.

2. Incidental prostate cancer: The main clinical symptom is benign prostatic hyperplasia. In the resected hyperplastic prostate tissue, prostate cancer is found by histological examination. Its histological manifestation is well-differentiated adenocarcinoma, mainly tubular adenocarcinoma and cribriform adenocarcinoma, and a few are poorly differentiated adenocarcinoma. The incidence of incidental prostate cancer abroad is 10% to 30%. The domestic incidence is reported to be about 5%.

3. Occult prostate cancer: The patient has no symptoms or signs of prostate disease, but pathological examination of lymph node biopsy or bone puncture specimens confirms prostate cancer. This can be further confirmed by prostate puncture biopsy. The serum prostate specific antigen (pSA) and prostate acid phosphatase levels of this type of patient are elevated. Immunohistochemical staining of pSA and (or) pAp in biopsy tissue is positive.

4. Clinical prostate cancer: Clinical examination (digital examination, ultrasound, CT or MRI, etc.) diagnoses prostate cancer and can be confirmed by biopsy. Increased serum pSA and pAp can also assist in diagnosis. Most patients can feel prostate nodules during rectal examination, and ultrasound examination shows that the prostate nodules are irregular in shape, uneven in echo and low in echo.

The four types introduced above are common types of prostate cancer. I hope everyone can understand. For men, you must pay attention to your health, take more physical exercise, eat more nutritious food, and don't always stay up late. Only in this way can you improve your body's immunity and avoid prostate cancer.
