Prostate 3+4 means that in the grading of prostate cancer, the score of major division is 3, the score of minor division is 4, and the total score is 7, which belongs to the intermediate-risk group. Prostate cancer usually occurs in older men, and its incidence is related to race, genetics, environment, and diet, etc. Most prostate cancers are follicular carcinomas with uneven differentiation. Most prostate cancers are graded using the Gleason grading system, which divides the tumor into major and minor grading zones according to the proportion of tissues in different forms in the tumor, with scores between 1 and 5, and the total sum is the sum of the two, with a score less than or equal to 6 being low-risk, a score of 7 being intermediate-risk, and a score greater than or equal to 8 being high-risk. Prostate 3+4 is the major grading zone and the minor grading zone is 3 and 4, the total is 7 points, for the intermediate risk group. In summary, if prostate disease exists, it is recommended to seek medical treatment and actively cooperate with the treatment to reduce the harm of the disease on the body.
