Understanding Prostate Cancer: A Growing Concern for Older Men
According to Professor Sun Yinghao from the Second Military Medical University Changhai Hospital, prostate cancer predominantly impacts men over the age of 50. In Western countries, this type of cancer has maintained the highest incidence among male malignancies for the past 15 years, overtaking lung cancer, while its mortality rate stands as the second highest among male cancers. In China, the incidence of prostate cancer is on the rise; for instance, the number of patients treated at Changhai Hospital in 2004 has seen a staggering increase of 30 times compared to the early 1980s.
Trends in Prostate Cancer Incidence
A study from the Shanghai Cancer Institute reveals that as of the year 2000, prostate cancer climbed from the third position to the top of the list among urogenital system malignancies. Its ranking among the top ten cancers in men has risen rapidly from ninth to seventh place.
Causes of Increased Incidence
Professor Ye Dingwei from the Fudan University Affiliated Tumor Hospital attributes the rising trend of prostate cancer to factors such as population aging and unhealthy dietary habits. High-fat, high-cholesterol, and high-energy foods have been linked to the onset of prostate cancer. The growing popularity of fast food in China has exacerbated these unhealthy eating patterns, contributing to the increased rates of prostate cancer among Chinese men.
Prostate Cancer Mortality Rates
Despite having a lower incidence compared to Western countries, the mortality rate of prostate cancer in China is rising annually. According to Professor Sun Yinghao, the escalating death rate can be mainly attributed to two factors: a lack of early diagnosis and a high misdiagnosis rate, as well as inconsistent treatment protocols.
Challenges in Diagnosis and Treatment
Professor Sun further notes that the current medical market can be confusing, with some practitioners lacking responsibility in their diagnostic approach. For younger patients, a missed diagnosis may still allow for corrective surgery. However, for older patients, particularly those over 70, the chances of undergoing subsequent surgical procedures decrease significantly.
Recommendations for Prevention and Early Detection
Experts recommend that men over the age of 50 should undergo an annual PSA (Prostate-Specific Antigen) test and consult with doctors at reputable medical institutions. While it's acknowledged that approximately 5% of patients may be overlooked during PSA testing, additional simple examinations can often confirm the presence of the disease.
In conclusion, as the incidence and mortality rates of prostate cancer continue to climb, awareness and proactive health measures are vital. Regular screenings and consultations with healthcare professionals can play a significant role in early detection and effective treatment.
