What causes ovarian cancer?
The causes of ovarian cancer, and its mechanism of onset, are not yet very clear. Some risk factors that have been relatively well established in relation to the occurrence of ovarian cancer include early menarche, which means starting menstruation at an earlier age, late menopause, and not having a history of pregnancy; these conditions are some of the risk factors for ovarian cancer. Additionally, the occurrence of ovarian cancer is also somewhat related to familial or genetic factors.
Lymphoma registration: which department?
Patients diagnosed with lymphoma can register under the departments of Hematology or Oncology, as both departments can administer chemotherapy. However, radiation therapy can only be conducted in the Oncology department. Each hospital may have slightly different categorizations for departments and diseases. However, for a patient initially presenting with lymphoma, who has not yet been diagnosed and primarily shows symptoms of painless lymph node enlargement, they can register under General Surgery. After completing necessary examinations like an ultrasound, if lymphoma is suspected, a lymph node excision biopsy is usually performed in General Surgery.
Can late-stage gastric cancer be treated?
Patients with late-stage gastric cancer generally may not have the opportunity for curative surgery, which is mainly suitable for early-stage gastric cancer patients. For late-stage gastric cancer patients, the treatment plan should be chosen based on the specific condition of the patient. If the patient's general condition is relatively good, chemotherapy can be an option. The type of chemotherapy, whether intravenous combination chemotherapy or oral drugs like tegafur capsules or capecitabine, which generally have milder reactions, depends on the patient's condition. Additionally, late-stage gastric cancer patients can try molecular targeted therapy, such as anti-angiogenesis drugs like apatinib, etc. Therefore, treatment options should be selected based on specific circumstances. The use of medications should be conducted under the guidance of a doctor.
How long can one live after ovarian cancer recurrence?
If ovarian cancer patients experience a recurrence after surgery and it is a simple local pelvic recurrence without distant organ metastasis, the treatment method involves evaluating whether another surgical resection can be performed by a gynecologist. However, if there is a recurrence combined with extensive pelvic metastasis, or metastasis to multiple organs, the treatment mainly involves chemotherapy. Therefore, how long a patient can live after ovarian cancer recurrence depends on the severity of the recurrence, the patient's physical condition, and the sensitivity to treatment, among other factors. Thus, it cannot be generalized as there is significant individual variation.
What are the symptoms of ovarian cancer?
Some early symptoms of ovarian cancer patients include a lump in the abdomen that can be felt during gynecological examination or by the patients themselves. In advanced ovarian cancer, as the tumor progressively enlarges, there may be symptoms like abdominal pain, bloating, decreased appetite, and weight loss. Moreover, the tumor may compress other organs in the pelvic cavity, causing symptoms such as a feeling of heaviness in the lower abdomen or even constipation. Additionally, many patients with ovarian cancer may develop significant ascites, which can also cause abdominal distension, decreased appetite, and even nausea and vomiting, along with other gastrointestinal symptoms.
How long can one survive with prostate cancer?
The life expectancy of prostate cancer patients depends on the clinical stage at diagnosis, as well as the patient's sensitivity to various treatments such as endocrine therapy, chemotherapy, and radiotherapy. Patients diagnosed at earlier stages who are more responsive to treatment generally have better treatment outcomes and, consequently, a longer survival period compared to those who are diagnosed at later stages and have poor responses to treatment. Overall, prostate cancer patients tend to have a relatively long disease course, and the prognosis is generally good. Even patients with advanced prostate cancer exhibiting extensive bone metastasis can survive several years due to the effectiveness of endocrine treatments. The disease itself progresses slowly, so the prognosis for this type of cancer is comparatively favorable.
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.
