What are the types of prostate cancer?

Among most cancers, prostate cancer is a very hidden one. It is difficult to detect whether you have the disease before the disease occurs. Experts divide prostate cancer into four categories based on the symptoms and signs before and after the onset of the disease, so that we can have a clearer understanding of what kind of disease prostate cancer is. So what are the types of prostate cancer? Let's introduce them in detail below.

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 above is the knowledge about the types of prostate cancer introduced to you. I believe that you can clearly understand the specific characteristics of each type of prostate cancer and what kind of disease prostate cancer is. I hope that you can prevent the disease if you are not healthy and treat the disease as soon as possible. Do not wait until the disease worsens before treating it, as this will cause considerable harm to the patient.
