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.
Ovarian cancer stage IC means
If it is stage Ic ovarian cancer, it refers to the tumor being confined to one or both ovaries, without involvement of other pelvic organs or distant organs such as the liver or lungs. However, it must meet any of the following conditions: the first is the rupture of the capsule with tumor on the surface; the second is the presence of cancer cells in the ascites or peritoneal lavage fluid. Meeting any of these conditions, along with the tumor being limited to one or both ovaries, classifies it as stage Ic.
Is there still hope for ovarian cancer recurrence?
Most ovarian malignant tumors, which are ovarian cancers, are relatively sensitive to chemotherapy. Therefore, in many cases, the treatment of ovarian cancer is a combination of surgery and chemotherapy. Even if ovarian cancer recurs, there are still many treatment options available, with chemotherapy being the most commonly used method. Many patients can still benefit from chemotherapy.
Primary liver cancer causes
The causes and specific mechanisms of primary liver cancer are not yet very clear; its development is a complex process involving multiple factors and steps, influenced by various aspects such as environment and diet. Primary liver cancer is associated with chronic hepatitis B and C virus infections, aflatoxin, contaminated drinking water, and alcoholic cirrhosis, among other factors. Particularly, hepatocellular carcinoma has a significant association with hepatitis B, and most patients may also have a history of chronic hepatitis B.
How long can one live with ovarian cancer?
The lifespan of ovarian cancer patients depends on several factors including the specific stage of the cancer, the patient's sensitivity and response to treatment, and the overall health of the patient, leading to significant individual variability. The cancer is typically classified into stages from one to four, with stage one being the earliest and stage four being the most advanced. Generally, patients diagnosed at an earlier stage tend to have a better prognosis and a greater chance of survival compared to those with advanced ovarian cancer. Additionally, patients in advanced stages who respond well to treatments like chemotherapy typically have a better prognosis and longer survival times compared to those who are less responsive to such treatments. Hence, it is impossible to generalize as the individual differences are substantial.
Can people with prostate cancer eat beef?
Patients with prostate cancer can eat beef. Beef is a high-protein food, and as cancer is a consumptive disease, it is generally advised to enhance nutrition in the diet, such as meats, proteins, vegetables, and fruits to maintain a balanced diet with both meat and vegetables. Avoid junk food, such as pickled vegetables from pickled jars, barbecue items, or excessively oily foods with high fat content. Those should be avoided as much as possible, but other foods, including beef, can be consumed.
Is pancreatic cancer contagious?
Pancreatic cancer, like other malignant tumors, is not contagious. Therefore, in clinical settings, including patients' families and accompanying healthcare staff often ask doctors if they might catch the disease while interacting with cancer patients. It is important to educate that malignant tumors, including pancreatic cancer, are not contagious. Contagious diseases refer to chronic conditions like hepatitis B, hepatitis C, tuberculosis, AIDS, etc., which can spread through contact with bodily fluids or blood of the affected individuals. However, malignant tumors are not infectious.
Is ovarian cancer curable?
Early-stage ovarian cancer patients, meaning those without extensive ascites buildup, and without widespread implant metastasis in the pelvic and abdominal cavity, and without metastasis to distant organs like the liver and lungs. These very early-stage ovarian cancer patients can undergo radical surgery. Postoperative treatment decisions, such as whether postoperative adjuvant radiotherapy or chemotherapy is needed, are based on the postoperative pathological report, which looks for high-risk factors for recurrence such as vascular cancer emboli or neural invasion. Through these treatment approaches, very early-stage ovarian cancer patients can achieve a cure, but this is not absolute. It's not guaranteed that every early-stage ovarian cancer patient can be cured, as there are individual differences. Clinically, if there is no recurrence or metastasis within five years, it is considered a cure.
