Can people with prostate cancer eat mutton?
Patients with prostate cancer can eat mutton. There is a folk belief about certain foods being "heaty", which refers to foods like mutton, beef, roosters, and bamboo shoots, often labeled as such and believed to be unsuitable for consumption. However, this belief is unscientific. From a medical perspective, patients with prostate cancer should primarily avoid junk food, such as barbecued items, pickled and smoked products, and especially oily and high-fat foods. Reducing the intake of these foods is recommended. Other than that, all other foods can be eaten, as long as there is a balanced nutrition and a good mix of meat, eggs, vegetables, and fruits. The idea of the so-called "heaty" foods is not scientifically based.
Is primary liver cancer hereditary?
The occurrence of tumors is related to multiple factors including genetics, environment, and the lifestyle habits of the patient. Therefore, primary liver cancer does have a genetic component. If parents, siblings, grandparents, etc., have a history of liver cancer, the offspring of such patients might have a higher probability of developing liver cancer compared to the general population. However, it's not absolute, as it also depends on other factors like environment, personal dietary habits, lifestyle habits, whether one has hepatitis, alcoholic liver cirrhosis, and other similar factors. Thus, those with a family history of liver cancer are likely to have a higher risk of developing the condition and should be more vigilant about disease screening. Screening should be more frequent than for the general population, but this is not an absolute rule.
What should I do if I can't stop vomiting due to pancreatic cancer?
Firstly, we need to ascertain the cause of the vomiting and can provide gastric protection and antiemetic treatment accordingly. If the vomiting is due to biliary obstruction caused by pancreatic cancer, resulting in severe jaundice and intense vomiting, in such cases, we can also place a stent surgically to drain the bile. The jaundice might be relieved afterwards, and accordingly, the vomiting symptoms might also be alleviated. Another aspect is, if the vomiting is caused by the tumor itself due to pancreatic cancer, we need to employ chemotherapy or some targeted or antiangiogenic treatments to control the tumor itself, and only then might the symptoms of vomiting be relieved.
How is prostate cancer treated?
The treatment principles of prostate cancer vary with different stages. For clinical stage T1-T2N0M0 prostate cancer, which is early-stage, patients can choose radical prostatectomy or radical radiotherapy. For patients with locally advanced prostate cancer, specifically staged T3 or T4 but without lymph node or distant metastasis, options include radiotherapy combined with hormonal therapy or solely hormonal therapy. For patients with distant metastasis, which indicates advanced-stage prostate cancer, treatment primarily involves hormonal therapy. If hormonal therapy fails, chemotherapy may be utilized. Additionally, for pain caused by bone metastasis, local radiotherapy or radionuclide therapy can be integrated into the comprehensive treatment approach.
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.
Lymphoma PR means "partial remission" of lymphoma.
"Lymphoma PR refers to an assessment of the effectiveness of chemotherapy. Typically, in clinical practice, after two rounds of chemotherapy, a comprehensive examination is conducted to assess the effectiveness of the treatment. PR stands for partial remission, which means that the measurable size of the tumor has reduced by at least 30% and has remained stable for four weeks. Clinically, this is referred to as PR, or partial remission, and it is an assessment of the effectiveness of chemotherapy."
Is prostate cancer sexually transmitted?
Prostate cancer is non-contagious; therefore, it cannot be transmitted through sharing utensils, eating together, or through respiratory pathways. Secondly, prostate cancer is not transmitted through sexual activity; it is non-contagious. In clinical settings, many family members of patients inquire whether malignant tumors are contagious and if they could be infected while caring for the patient. It is important to clarify that malignant tumors are not contagious, and prostate cancer cannot be transmitted through sexual activity.
The difference between lymphoma and lymphatic cancer
Cancer, commonly referred to as malignant tumors in everyday language, is generally known to the public simply as cancer—for example, lung cancer, liver cancer, colon cancer, etc. It specifically refers to malignant tumors that occur in epithelial tissue, which we call cancer. Lymphoma, on the other hand, refers to malignant tumors that occur in lymph nodes, or in extranodal organs or tissues, which we call lymphoma. There are also malignant tumors that occur in mesenchymal tissue, known as sarcomas. In fact, lymphoma is also a type of malignant tumor, so people commonly refer to it as lymphatic cancer. Therefore, lymphoma and lymphatic cancer are essentially the same disease, with lymphatic cancer specifically referring to lymphoma.
How is esophageal cancer staged?
The staging of esophageal cancer includes a preoperative clinical staging and a postoperative pathological staging. Clinical staging involves completing various systemic examinations, determining the extent of the tumor, whether there are lymph node metastases, and whether there are distant metastases to organs such as the liver and lungs. This requires thorough assessments, including esophageal endoscopic ultrasound and whole-body examinations like PET-CT, to conduct clinical staging. Postoperative pathological staging, on the other hand, is determined based on the depth of tumor invasion reached during surgery and the status of lymph node metastasis, among other factors.
Is chemotherapy for gastric cancer torturous?
The first common side effect of chemotherapy drugs is gastrointestinal reactions, such as nausea, vomiting, decreased appetite, diarrhea, constipation, or bloating, and other such gastrointestinal symptoms. The second is bone marrow suppression, such as decreases in white blood cells and platelets; a decrease in white blood cells can easily lead to infections, and low platelets can lead to a tendency to bleed. There are also liver and kidney damage, numbness of hands and feet in the peripheral nervous system, and clinical symptoms such as fingernail darkening, pigmentation, or hand-foot syndrome caused by fluorouracil. The severity of chemotherapy side effects varies greatly among patients and is related to each patient's general condition, exhibiting significant individual differences. Some patients may experience severe reactions to chemotherapy, while others may have milder reactions. However, during chemotherapy, we provide corresponding symptomatic treatments such as gastric protection, antiemetics, and cardioprotection, among others, to try to minimize the side effects caused by chemotherapy.
