Can ovarian cancer that has spread still be cured?
If ovarian cancer has spread, it is generally considered to be at an advanced stage. The treatment for advanced ovarian cancer primarily involves chemotherapy. Epithelial cancer, the most common type of ovarian cancer, is particularly sensitive to chemotherapy. Most patients benefit from chemotherapy. However, once ovarian cancer has spread and is not caught at a very early stage, even with treatments like chemotherapy, it cannot be cured. The purpose of treatment at this stage is to alleviate the patient's pain and extend their survival, but it cannot be cured.
Can prostate cancer be detected by color ultrasound?
Ultrasound is also a method for screening prostate cancer, but it is generally combined with Prostate Specific Antigen (PSA) for a comprehensive consideration in prostate cancer screening. If prostate nodules are found during a prostate color Doppler ultrasound, the differentiation between prostate cancer and benign prostatic nodules can be aided by the variations in internal echoes, but this is only a reference and cannot be 100% certain. Thus, in clinical practice, it is also combined with PSA for a comprehensive evaluation. Generally, a PSA greater than 10 suggests a higher likelihood of malignancy. The diagnosis of prostate cancer requires a biopsy to confirm the pathology.
Is lymphoma the same as lymphatic cancer?
Lymphoma refers to a type of malignant tumor that originates in lymph nodes or extranodal tissues or organs. The cancer we usually talk about refers to malignant tumors originating from epithelial tissues, which we call cancer, such as lung cancer, liver cancer, etc. Therefore, lymphoma is actually what non-medical professionals commonly refer to as lymphatic cancer. It is simply called lymphoma instead of cancer because it originates in lymph nodes or extranodal tissues or organs, and therefore, it is termed malignant lymphoma, which in layman's terms is lymphatic cancer.
What is early-stage gastric cancer?
In the early stages of gastric cancer, the tumor is confined to the mucosa or submucosa, regardless of whether there is regional lymph node metastasis or not; this is still classified as early-stage gastric cancer. The treatment for early-stage gastric cancer primarily involves curative surgery, which is the first option unless the patient is of advanced age or has severe underlying diseases that prevent tolerance of surgical treatment. Excluding these cases, surgical treatment is generally the first choice. Furthermore, the outcome of surgical treatment for patients with early-stage gastric cancer is generally quite positive, with a five-year survival rate typically exceeding 80%.
Is prostate cancer radiotherapy painful?
Prostate cancer radiotherapy involves high doses of radiation, which typically results in related side effects. However, the severity of these side effects varies from patient to patient depending on individual factors such as their physical constitution. Therefore, clinically, some patients may experience severe symptoms, while others may have milder symptoms, indicating significant individual differences. Common side effects of radiotherapy include radiation cystitis, characterized by frequent urination, urgency, and possibly hematuria. Radiation proctitis is also common, presenting symptoms such as a sensation of heaviness around the anus and diarrhea. Additionally, bone marrow suppression, manifesting as a decrease in white blood cells and platelets, is another side effect.
Will ovarian cancer recur after complete resection?
After complete removal of ovarian cancer, there is still a possibility of recurrence, especially in patients with high-risk factors. The recurrence rate can be quite high, for example, if there was rupture of the capsule, low differentiation of the pathology, presence of tumor tissue on the surface of the ovary, severe adhesion of the tumor to the surrounding areas, cancer cells found in the abdominal lavage fluid, or presence of vascular tumor thrombus and nerve invasion. Even after total removal, recurrence can still occur.
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.
