Prostate cancer is the most common malignant tumor in the male urinary reproductive system, with 80% of cases occurring in elderly individuals over the age of 65. From an etiological perspective, a high-fat diet may be a contributing factor to prostate cancer. However, we know that malignant tumors are consumptive diseases, and nutritional status is crucial during the treatment and recovery process, especially in elderly individuals with weaker constitutions. Therefore, patients with malignant tumors should ensure adequate nutrition intake, particularly protein intake. Milk and eggs are common foods for the general population and offer a cost-effective source of nutrition. They can be included in the diet of prostate cancer patients. Of course, dietary intake should focus on healthy proportions. It is not about consuming only milk and eggs at every meal but maintaining a normal and healthy dietary balance, which is better for the patient.

Is vomiting in prostate cancer due to metastasis to the liver?

Patients with prostate cancer may experience vomiting due to the metastasis of the disease to the liver, causing damage to liver function. However, vomiting could also be caused by other reasons, such as the metastasis of prostate cancer to the peritoneum of the abdominal cavity. Clinically, this can lead to cancerous intestinal obstruction, with symptoms commonly including vomiting, abdominal pain, bloating, reduced bowel movements and gas, or cessation of bowel movements and gas. When prostate cancer metastasizes to the brain, the increased intracranial pressure can also cause symptoms such as vomiting, headache, swelling of the optic disc, hemiplegia, and aphasia. Additionally, some prostate cancer patients may experience vomiting due to toxic side effects from treatments such as chemotherapy and targeted therapy.

What are the symptoms of prostate cancer?

Patients with early-stage prostate cancer do not exhibit obvious clinical symptoms. In the advanced stage of the disease, symptoms such as obstruction of the bladder outlet or the ureters can occur, manifesting as difficulty urinating, poor urine flow, frequent urination, hematuria, or purulent urine. Additionally, most prostate cancer patients are prone to multiple bone metastases, which cause pain at the sites of metastasis. This is also a common clinical symptom.

What indicators are checked for prostate cancer?

Prostate-Specific Antigen (PSA) is a glycoprotein produced by the vesicles in the cytoplasm of normal or pre-cancerous epithelial cells of the prostate. It is the most specific and sensitive tumor marker for prostate cancer. Therefore, in patients with prostate cancer, we generally conduct blood tests for PSA, especially in screening for prostate cancer, assessing the effectiveness of treatments, and for the prognosis of prostate patients, among other aspects. Additionally, other examinations are combined, such as digital rectal exams, which can also serve as a screening method for prostate cancer. Moreover, CT or MRI scans of the prostate and pelvis, as well as ultrasound examinations of the prostate, can be used in conjunction with the tumor marker PSA for a comprehensive evaluation.

What are the causes of prostate cancer?

At present, there are many factors that cause prostate cancer, but its exact etiology remains unclear. It may be related to genetic factors, gene changes, prostate gonococcal and chlamydial infections, intensity of sexual activity, and the influence of hormones. Additionally, dietary habits, long-term consumption of high-fat foods, and occupational hazards, such as excessive exposure to chromium, may also be related to the development of the disease.

Pathological classification of prostate cancer

The classification of precancerous lesions of prostate cancer is divided into two categories: intraductal carcinoma of the prostate and atypical adenomatous hyperplasia. Among these, the relationship between intraductal carcinoma of the prostate and prostate cancer is the closest. Intraductal carcinoma of the prostate is currently recognized as a precancerous lesion of prostate cancer, while atypical adenomatous hyperplasia has not been proven to be a precancerous lesion of prostate cancer according to current evidence. However, the biological behavior of this atypical adenomatous hyperplasia is not very clear yet, so it should be closely monitored. The histological classification of prostate cancer mainly includes the majority of acinar adenocarcinoma and a small amount of ductal adenocarcinoma, with acinar adenocarcinoma being a highly invasive malignant tumor.
