Can prostate cancer be detected by ultrasound B?
Prostate cancer can generally be detected through ultrasound, as it reveals nodules in the prostate. By examining the internal echoes of these nodules, one can differentiate between benign and malignant prostate conditions. Thus, in foreign countries, ultrasound, specifically prostate color Doppler ultrasound examinations, are used as a screening method for prostate cancer. In China, screening methods also include traditional digital rectal examinations and generally involve blood tests for specific prostate tumor markers, namely PSA. These tests are combined with prostate ultrasound for a comprehensive assessment.
Does ovarian cancer hyperthermic intraperitoneal chemotherapy work?
Patients with ovarian cancer are prone to peritoneal metastasis, so many patients develop ascites during the discovery of the disease or its progression. A large amount of ascites is a common concurrent symptom in patients with ovarian cancer. For patients with significant ascites like this, hyperthermic intraperitoneal chemotherapy (HIPEC) can be performed, which involves infusing chemotherapy drugs into the abdominal cavity and then combining it with thermotherapy. This treatment generally has a decent effect, especially in controlling the spread of cancer cells in the peritoneum and managing ascites.
early symptoms of Hodgkin's lymphoma
Malignant lymphoma refers to a type of malignant tumor that originates in the lymph nodes or extranodal organs or tissues. Therefore, Hodgkin's lymphoma is a type of lymphoma. Its early symptoms mainly start with the enlargement of superficial lymph nodes throughout the body, with 90% of Hodgkin's lymphoma patients presenting with enlargement of superficial lymph nodes as an early symptom when they seek medical advice. The most common superficial lymph nodes are those above the collarbone and in the neck, but enlargement can also occur in the axillary and inguinal lymph nodes, which are also some of the more common early clinical manifestations seen in practice.
What causes prostate cancer?
The causes of prostate cancer are not yet very clear. Its occurrence may be related to gonorrhea of the prostate, or viral and chlamydial infections of the prostate, as well as the intensity of sexual activity and the influence of hormones, which may have some connection to the development of prostate cancer. Additionally, a high-fat diet and some occupational factors, such as excessive exposure to chromium, may also be related to the onset of prostate cancer.
What can stomach cancer patients eat?
For patients with gastric cancer, there are no specific dietary taboos, except for avoiding foods that are too spicy or greasy, such as fried foods and barbecued items that are difficult to digest. Additionally, it is advisable to avoid carbonated and very cold foods that may irritate the stomach. The dietary approach should focus on eating smaller, more frequent meals that are easy to digest and bland. However, it is also important to ensure a balanced diet that includes both meat and vegetables to ensure adequate nutrition for the patient.
Is lung cancer contagious?
The occurrence of lung cancer is associated with smoking, air pollution, and working in environments such as coal mining. However, lung cancer is not contagious. Therefore, in clinical settings, family members of patients often ask doctors whether lung cancer can be transmitted through the respiratory tract. It can be assured that lung cancer is not contagious; only communicable diseases like tuberculosis can be spread this way.
How long can one live after rectal cancer surgery?
The specific life expectancy after radical resection for rectal cancer varies among individuals and is dependent on various factors including the patient's general and physical condition, pathological staging post-surgery, and whether there are high-risk factors for recurrence such as lymph node metastasis, vascular tumor thrombus, and nerve invasion. The overall five-year survival rate post-surgery is approximately 50%. If the disease is confined to the submucosa and lacks high-risk factors such as vascular tumor thrombus, nerve invasion, or lymph node metastasis, the five-year survival rate after radical surgery can reach up to 90%. However, if post-surgery pathology reveals lymph node metastasis, vascular tumor thrombus, and nerve invasion, among other high-risk factors, the patient's five-year survival rate will decrease. Thus, survival rates are closely related to many factors.
Ovarian Cancer Dietary Precautions
The occurrence of ovarian cancer is not greatly related to dietary habits, so there are no special dietary restrictions or forbidden foods for patients with ovarian cancer. In Western medicine, unlike Traditional Chinese Medicine, which mentions certain "stimulating foods," there are no such prohibitions. Therefore, the diet for patients with ovarian cancer is the same as for anyone else, only requiring a balanced, comprehensive nutrition, and a combination of meat and vegetables. There are no special dietary considerations needed.
Dietary therapy for lung cancer
In the diet of lung cancer patients, Western medicine does not have the concept of "trigger foods" like Chinese medicine does. According to Western medicine, there are no specific dietary restrictions; the focus is on maintaining a balanced diet as usual, incorporating meat, proteins, vegetables, and fruits to ensure nutritional balance. Generally, lung cancer patients may experience coughing symptoms, so it is advisable to consume a light diet avoiding oily fried foods. Extremely spicy foods can provoke irritative coughing and worsen it, so they should be avoided, along with barbecued and pickled foods, and junk food. Other than that, the diet should be similar to a normal balanced diet. For patients undergoing chemotherapy, a high-protein diet is recommended, preferably consisting of steamed or stewed dishes. These can be combined with traditional Chinese medicinal herbs such as Astragalus, American ginseng, and Dong quai, which are known to boost energy and enhance resistance, thus aiding in dietary therapy to strengthen the patient's immunity.
Are all lymphomas malignant?
Tumors can be benign or malignant; malignant tumors are commonly referred to as cancer. Lymphoma, because it originates from lymph nodes or tissues or organs outside the lymph nodes, is a type of malignant tumor, and thus it is called lymphoma. All lymphomas are malignant; there are no benign lymphomas. However, based on specific pathological types, lymphomas are classified into two main categories: non-Hodgkin lymphoma and Hodgkin lymphoma, but all lymphomas are malignant.
