There is no direct relationship between the chance of prostate nodules becoming cancerous and the size of the nodules. Prostate nodules are hard nodules found in the prostate gland during physical examination, and their causes mainly include prostate stones, prostate inflammation, benign prostatic hyperplasia and prostate tumors, etc. Prostate nodules are classified into benign and malignant nodules by the nature of lesions. Prostate nodules are categorized into benign and malignant nodules by the nature of the lesion, but the size of the nodule is not a factor in determining whether the nodule is benign or malignant, and there is no direct relationship between the two. To clarify the nature of prostate nodules, first of all, we need to improve all kinds of laboratory tests, including prostate fluid examination, prostate ultrasound, magnetic resonance imaging, CT examination, as well as prostate-specific antigen test, etc., and if necessary, we need to improve the pathology test. If prostate nodules are found, further diagnosis and treatment are recommended.
