What are the signs of prostate cancer? What tests are needed to diagnose prostate cancer?

There are no symptoms in the early stages of prostate cancer. It is usually diagnosed through physical examinations. If conditions permit, you can have a physical examination every year. In this case, for early prostate cancer, blood tests can sometimes be used to detect prostate cancer, and specific antigens can be used to identify the possibility of prostate cancer. This is in the early stages. If prostate cancer develops to a certain stage, frequent urination, urgency, difficulty urinating, and discomfort in the perineum may occur. These symptoms are often not very early. At this time, pSA, prostate color ultrasound, rectal examination, and prostate magnetic resonance imaging are required. Finally, a clear diagnosis is made through puncture. Metastasis may occur in the late stages of prostate cancer, especially bone metastasis. At this time, the patient may have bone pain. Depending on the site of metastasis, it may be the spine, ilium, thigh bone, etc. The chance of metastasis is relatively high. At this time, the patient will have bone pain, and a bone scan can confirm the diagnosis or a pET-CT can be performed.
