Can people with lymphoma eat lamb?
Patients with lymphoma do not have any specific dietary restrictions, unlike traditional Chinese medicine, which refers to certain "heaty" foods that should be avoided. In Western medicine, as long as the diet is nutritionally balanced, including meat, protein, vegetables, and fruits, it fulfills the requirements of a balanced and comprehensive nutrition. The aim is to enhance the patient's immune system. There are no specific foods that are forbidden, so foods like lamb and beef can be consumed by lymphoma patients.
Does lymphoma infect family members?
Lymphoma and other malignant tumors, such as lung cancer, breast cancer, intestinal cancer, liver cancer, etc., are all non-contagious. Therefore, even if you live with your family every day, you do not have to worry about transmitting malignant tumors to your family members; they are not contagious. When we refer to contagious diseases, we call them infectious diseases, common ones include tuberculosis, hepatitis B, hepatitis C, H1N1, etc. These are contagious diseases, but malignant tumors are not contagious and will not be spread to family members.
ovarian cancer specific drug
Ovarian cancer does not have any specific cure-all treatment. Most ovarian cancers are epithelial ovarian cancers, and there is also ovarian cancer resulting from malignant germ cells, which is a rarer pathology type. For epithelial ovarian cancer, treatment methods include surgery, radiation therapy, chemotherapy, and some targeted therapies, mainly using Bevacizumab, which is a monoclonal antibody that inhibits angiogenesis, and is usually used in combination with chemotherapy drugs. For patients with advanced ovarian cancer, those who are resistant to chemotherapy, or those in poor general health unable to endure chemotherapy, palliative treatments like hormone treatment using progestogens are an option, along with immune therapy being available nowadays. Surgery is primarily for early-stage ovarian cancer patients, where curative surgical resection is possible, or for debulking surgery in patients with advanced ovarian cancer. Chemotherapy is frequently used as it is relatively effective for epithelial ovarian cancer, a type of cancer that is somewhat sensitive to such treatments. The drugs used mainly include taxane combined with platinum-based chemotherapy. For intravenous administration or intraperitoneal delivery—for the latter, mainly for ovarian cancers complicated by extensive ascites—, positioning an abdominal drainage tube and then infusing platinum-based chemotherapy drugs into the abdominal cavity are utilized.
Symptoms of ovarian cancer brain metastasis
Patients with ovarian cancer experiencing brain metastases are relatively uncommon in clinical settings. The primary symptom of brain metastasis is intracranial hypertension, which includes severe headaches, dizziness, nausea, and vomiting, including projectile vomiting during meals — all symptoms of increased intracranial pressure. Additionally, if there is significant brain swelling, the patient may experience weakness in the limbs on the opposite side of the body, similar to symptoms of paralysis seen in stroke patients. Furthermore, if the brain metastasis leads to the formation of a brain herniation, the patient may experience symptoms such as coma.
Can ovarian cancer be cured?
Whether ovarian cancer can be cured depends on the clinical stage of the patient, as well as the patient's sensitivity to treatment, among other factors. If it is a case of early-stage ovarian cancer, curative surgery can be performed. After surgery, based on the pathology, it can be decided whether postoperative adjuvant radiotherapy or chemotherapy is necessary. Patients with early-stage ovarian cancer who undergo surgery or postoperative adjuvant radiotherapy and chemotherapy may have hope for a cure. However, if the cancer is discovered at a late stage where it has spread extensively, such as widespread metastasis to the pelvic area, or even to distant organs like the lungs or liver, then the treatment for these patients is primarily chemotherapy. A cure is not achievable; the treatment aims to alleviate symptoms and prolong the patient's life. Thus, for patients with late-stage ovarian cancer, treatment cannot achieve a curative purpose.
How is pancreatic cancer diagnosed?
The most common symptoms of pancreatic cancer are pain in the upper abdomen and jaundice. During physical examination, a mass in the upper abdomen can be felt, which is a common symptom. When these symptoms appear, further abdominal ultrasound or CT scans should be performed, as these two are the most commonly used imaging methods for diagnosing pancreatic cancer. Additionally, pancreatic MRI or PET-CT can also help enhance the diagnostic accuracy for pancreatic cancer. MRCP and ERCP are also used to assess the bile ducts and to evaluate the feasibility of surgery. Blood tests for pancreatic cancer-related tumor markers, such as carcinoembryonic antigen (CEA) and CA19-9, are commonly performed, with CA19-9 being particularly sensitive and specific for the diagnosis of pancreatic cancer.
The difference between rectal cancer and colon cancer lies in the location of the cancer. Rectal cancer occurs in the rectum, which is the final part of the large intestine, while colon cancer occurs in other parts of the colon.
Rectal cancer and colon cancer are collectively referred to as colorectal cancer, named according to the different locations where the tumors occur. Rectal cancer occurs in the rectum. Colon cancer includes tumors in the transverse colon, descending colon, ascending colon, and sigmoid colon, and tumors in these areas are called colon cancer. Both are known as colorectal cancer, and they exhibit similar clinical manifestations, including rectal bleeding, abdominal pain, and changes in bowel habits, such as constipation, diarrhea, alternating constipation and diarrhea, and changes in stool shape, such as narrowing of the stool. They are merely named differently based on the location of the tumors and are collectively referred to as colorectal cancer.
How to check for gastric cancer?
Gastroscopy is very important in the examination of gastric cancer, and taking a biopsy under gastroscopy is an important means of diagnosis. Other examinations include endoscopic ultrasound or enhanced abdominal CT and chest CT to assess the staging of the patient. With endoscopic ultrasound, we can see which layer of the stomach wall the tumor has invaded and then combine it with chest and abdominal CT scans to assess whether there is distant metastasis. Diagnosis requires gastroscopy with a biopsy taken during the procedure.
Which test for pancreatic cancer is the most accurate?
Abdominal ultrasound and abdominal CT scans are the most commonly used imaging methods for diagnosing pancreatic cancer. Additionally, it is important to consider the patient's symptoms and blood tests for tumor markers, mainly IP antigen, CEA, and CA19-9. Confirming pancreatic cancer requires a biopsy to find cancer cells, which is the gold standard for diagnosis. Other tests can serve as screening and adjunct diagnostic tools. Confirmation requires a biopsy for pathological diagnosis or direct radical surgery followed by a postoperative pathological confirmation.
The difference between esophageal cancer and laryngeal cancer
Esophageal cancer and laryngeal cancer are both malignant tumors. Esophageal cancer refers to the malignant tumor occurring in the esophagus, while laryngeal cancer refers to the malignant tumor occurring in the larynx. Therefore, their tumor locations are different. The pathology of both is generally squamous cell carcinoma. The main symptom of esophageal cancer is obstructed eating; patients will feel difficulty swallowing, obstruction, and worsening of these symptoms as they eat. The primary symptom of laryngeal cancer is typically a hoarse voice, which distinguishes the symptoms of the two cancers.
