Men's Health Science: How Close Is Prostate Cancer To Men

Prostate cancer is a malignant tumor that occurs in male prostate tissue and is the result of abnormal and disordered growth of prostate acinar cells, with significant geographic and ethnic differences in incidence. In developed countries and regions such as Europe and the United States, it is the most common malignant tumor in men.

How can prostate cancer be detected early?

At present, it is accepted that the easiest way to screen for prostate cancer is a combination of digital prostateectal examination and serum PSA testing, both of which play an important role in screening.

The vast majority of normal prostate cancers are found by PSA abnormalities, accounting for 80% of cases, while digital rectal examination reveals nodular abnormalities in only 20%. Usually men should start prostate cancer screening at age 50; If you have a family history of prostate cancer, you should start prostate cancer screening at the age of 40.

What are the risk factors for prostate cancer?

(1) Age: With the increase of age, the incidence of prostate cancer increases sharply, and the vast majority of prostate cancer patients are older than 65 years old. Basically, the incidence of prostate cancer almost doubles for every 10 years of age after the age of 40, and the risk of prostate cancer in men aged 50~59 is 10%, while the risk of prostate cancer in men aged 80~89 years increases sharply to 70%.

(2) Family history: When there is an immediate male relative in the family who suffers from prostate cancer, the incidence of male cancer in the family is significantly higher.

(3) Ethnicity: Prostate cancer has the highest incidence among African Americans (i.e., Black Americans), while the incidence of prostate cancer in Black Africans is the lowest in the world. Whether it is Chinese mainland, Taiwan, Hong Kong, Japan, South Korea, Singapore, the incidence of prostate cancer is increasing year by year.

(4) Diet: Some studies have shown that men who regularly consume foods high in animal fat are also prone to prostate cancer, and the mortality rate of prostate cancer is related to total fat intake. People who usually eat a diet rich in vegetables and fruits are less likely to get sick.

(5) Androgen levels: High androgen levels in the body are also one of the possible causes of prostate cancer. Androgens can promote the growth of prostate cancer.

What are the manifestations of prostate cancer?

Prostate cancer mostly originates from the peripheral zone of the prostate, the onset is more insidious, and the growth is relatively slow, so early prostate cancer can have no warning symptoms, and once symptoms appear, it is often a more advanced advanced prostate cancer. Symptoms include the following:

(1) Progressive dysuria, manifested as thin urine stream, crooked urine flow, bifurcation or prolongation of urine flow, frequent urination, urgency, painful urination, incomplete urge to urinate, etc., and urine dripping and urinary retention in severe cases.

(2) For advanced advanced prostate cancer, symptoms such as fatigue, weight loss, and general pain may occur.

(3) When prostate cancer metastasizes to bone, it can cause bone pain at the metastasis site.

(4) For advanced prostate cancer with spinal metastasis, if the spine is fractured or the tumor invades the spinal cord, it can lead to nerve compression, and then cause paralysis, and it is necessary to go to the hospital for emergency treatment immediately.

(5) If prostate cancer invades the bottom of the bladder or pelvic lymph nodes metastasize extensively, unilateral or bilateral ureteral obstruction will occur. Symptoms and signs of ureteral obstruction include oliguria, low back pain, nausea, vomiting, and fever in the presence of infection.

(6) Prostate cancer is usually not accompanied by hematuria and hematospermia, but once hematuria and hematospermia appear, you should go to the urology outpatient clinic for relevant examinations to rule out the possibility of prostate or seminal vesicle gland tumors.

Can prostate cancer be cured?

Early prostate cancer can be cured by radical prostatectomy, so early screening and early diagnosis of prostate cancer should be emphasized. However, for advanced prostate cancer, it cannot be removed by surgery, and can only be treated with endocrine therapy, radiotherapy, and chemotherapy, but the effect is not good.

What should I pay attention to when it comes to prostate cancer diet?

1. High-fat diet will stimulate the growth of prostate cancer, reducing high-fat diet can reduce the incidence of prostate cancer, beef and high-fat dairy products seem to be stimulants of prostate cancer, and the intake of large amounts of dairy products can increase the risk of prostate cancer.

2. Fruits and vegetables and a low-fat diet may help reduce the risk of prostate cancer, including soybeans, tomatoes, pomegranates, red grapes, strawberries, garlic and citrus, etc., soybeans contain phytoestrogens, similar to estrogen in women's bodies, which can reduce the risk of prostate cancer.

3. Green tea contains a variety of antioxidants, which can reduce the incidence of prostate cancer.

4. Many fish such as the role of preventing cardiovascular diseases and cancer.

5. Selenium in the diet is mainly found in animal liver, seafood, whole grains, milk and dairy products, mushrooms, garlic and asparagus and other foods, which may reduce the incidence of prostate cancer.

What are the lifestyles for prostate cancer?

1. Maintain an appropriate weight, insist on physical exercise, and the amount of exercise should be appropriate.

2. Choose a plant-based diet; Do not smoke or drink too much; Limit fat intake to no more than 20% of total calorie intake.

3. Don't eat junk food and try to avoid saturated fats in your diet; Eat more fish, fish are rich in some kind of beneficial fatty acids; Eating fruits and vegetables every day, and limiting sugar and salt, can both prevent cancer and keep your heart healthy.

4. Eat more fiber-rich foods and soy products every day, such as low-fat soybean milk, tofu, bean protein powder, etc.; Take adequate doses of calcium and vitamin D to prevent osteoporosis.
