What is prostate cancer? What are the benefits of a new prostate cancer screening system

According to the Daily Mail of the UK, researchers have recently developed a new prostate cancer detection system that allows patients to undergo surgery first. The birth of new instruments has brought good news to many prostate cancer patients.

56 year old male John Murphy was diagnosed with prostate cancer in November last year. According to his blood routine, his prostate specific antigen is high. John Murphy's first reaction was to have a prostatectomy as soon as possible, and urologists also believed that this operation was the best choice. Because after prostatectomy, cancer no longer exists. But this type of surgery also comes with certain risks, as it may damage the nerve tissue near the prostate, leading to postoperative urinary incontinence and impotence.

At first, John was happy to have surgery to treat his illness, but three days before the surgery, he changed his mind. I hope to have more time to consider. I am still young and have a good relationship with my wife.

Afterwards, John came to a certain institution for inspection. This test is to study the genes of tumors, determine whether cancer cells are at high risk, and then decide whether surgery is necessary. John's inspection fee is approximately £ 1200. A week later, he came to the conclusion that prostate cancer is at low risk, with slow growth of cancer cells and no need to remove the prostate. Approximately 40000 men in the UK are diagnosed with prostate cancer every year, and approximately 10000 die from prostate cancer each year.

Dr. Haley Whitaker, the top scientist at the UK Cancer Research Centre, said that about a quarter of prostate cancer is at high risk. These cancer cells grow rapidly and spread to other parts of the body, which requires some form of treatment. The remaining three-quarters of prostate cancer are low-risk. By monitoring the condition of cancer, sometimes it can gradually improve without treatment.

Now, a new detection system called bats can determine whether cancer is at high risk by detecting the positivity and changes in genes.

The Prolaris examination is surprising and can now be used to determine whether patients need to continue treatment. The researcher said excitedly.

What is prostate cancer?

Prostate cancer refers to an epithelial malignant tumor that occurs in the prostate. According to the WHO Pathology and Genetics of urinary system and Male Genital Organ Tumors in 2004, the pathological types of prostate cancer include adenocarcinoma (acinar adenocarcinoma), ductal adenocarcinoma, urothelium carcinoma, squamous cell carcinoma and adenosquamous carcinoma. Among them, prostate adenocarcinoma accounts for over 95%, so what we usually refer to as prostate cancer is prostate adenocarcinoma. In 2012, the incidence rate of prostate cancer in tumor registration areas in China was 9.92/100000, and the incidence rate of male malignant tumors ranked sixth. The onset age was at a low level before 55 years old, and gradually increased after 55 years old. The incidence rate increased with age, and the peak age was 70-80 years old. Patients with familial inherited prostate cancer have an earlier onset age, with 43% of patients aged ≤ 55 years old.
