The development speed of prostate cancer is directly related to the malignant degree of the tumor. If the malignant degree of prostate cancer is relatively low and the disease develops slowly, it usually takes 10 years or even more to go from early to advanced stage. However, if the malignant degree of prostate cancer is high, it may take 6 to 12 months from early stage to advanced stage, and it is recommended to go to the hospital for treatment in time. Prostate cancer is a common malignant tumor that mostly occurs in elderly male patients, and most of them belong to androgen-dependent tumors, with slow development and low invasiveness, which belong to medium-low risk tumors and low malignant degree, so it takes about 10 years or even longer to go from the early stage to the late stage, but there are some patients with lifelong non-progression. There are also some prostate cancer patients with rapid progression, high aggressiveness, poor cell differentiation and high malignancy, and it may only take 6 to 12 months for these patients to go from early to advanced stage, so patients are advised to go to the hospital in time for treatment, and take chemotherapy, radiotherapy and other treatments under the guidance of doctors. When diagnosed with prostate cancer, patients are advised to actively cooperate with doctors’ treatment and inform doctors of any discomfort to avoid aggravating the condition.
