Understanding Prostate Cancer and Its Treatment
At 55 years old, Mr. Zhang had been enduring significant discomfort due to urinary difficulties and hematuria. Recently, he sought treatment at a municipal hospital. After a thorough assessment and a Prostate-Specific Antigen (PSA) test, Professor Lai Haibiao from the urology department suspected early-stage prostate cancer. Subsequent examinations confirmed this diagnosis.
Diagnosis and Surgical Intervention
Taking into account Mr. Zhang's pathologic results, Professor Lai analyzed his health status alongside the stage and nature of the cancerous changes. A laparoscopic prostate cancer radical surgery was recommended. The surgery lasted approximately five hours, and Mr. Zhang was able to eat and move around the day after the procedure.
The surgery utilized a high-definition laparoscopic system implementing small incisions of just 5-10 mm. This minimally invasive approach allowed for precise operations, including the separation of peritoneal fat, opening of the pelvic fascia, and complete removal of the prostate while preserving the urethra. The entire process went smoothly, with Mr. Zhang's recovery being notably fast.
The Rise of Prostate Cancer
Prostate cancer has become a significant health concern globally, particularly affecting men's health as they age. It is reported that over 95% of diagnosed prostate cancer patients are between 45 and 89 years old. In developed Western countries, prostate cancer ranks as the most common malignant tumor among men, with a mortality rate second only to lung cancer.
As China's economy continues to advance, the aging population has contributed to a sharp increase in prostate cancer incidents. Reports indicate that the incidence of prostate cancer in Shanghai has become the highest among male urological malignancies.
Impact of Sexual Activity on Prostate Cancer Risk
Recent studies from Harvard have highlighted the relationship between sexual activity and prostate cancer risk. Men who engage in regular sexual activity—specifically those who ejaculate once a day—exhibit lower chances of developing prostate cancer. The research found that men aged 40-49 who ejaculate 21 times or more per month could reduce their risk of cancer by 22%.
The study tracked 32,000 healthy men over 18 years, resulting in 3,839 diagnoses of prostate cancer. Notably, men aged 20-29 and 40-49 were asked about their average monthly ejaculation frequency. Observations indicated that more frequent ejaculation throughout a man's lifetime correlates with a reduced risk of prostate cancer. This conclusion holds true even when accounting for factors such as diet, lifestyle, and family history of the disease.
Preventing Prostate Cancer: Key Recommendations
While the exact causes of prostate cancer remain unclear, the risks increase with age. Preventive measures to consider include:
- Regular Screening: Men are advised to begin annual rectal and PSA exams at age 50. Those with a family history should start screenings at age 40.
- Awareness of Symptoms: Pay attention to symptoms such as frequent urination, urgency, incomplete urination, or blood in urine, and seek medical attention if these occur.
- Maintain a Healthy Weight: Obesity is linked to an increased risk of prostate cancer, potentially affecting hormonal levels.
- Incorporate Legumes in Diet: The dietary habits of Japanese men, rich in low-fat and high-fiber foods including soy products, correspond with a significantly lower prostate cancer mortality rate compared to their American counterparts.
- Caution with Hormone Supplements: While testosterone therapy may enhance quality of life, high doses can be associated with prostate enlargement and tumors. It is advisable to avoid these supplements if facing prostate issues.
By understanding the risks and taking proactive measures, men can contribute to their prostate health and potentially lower their chances of developing prostate cancer.
