Can atrophic gastritis lead to gastric cancer?
The development of gastric cancer, particularly intestinal-type gastric cancer, is a multi-stage process influenced by various factors. Chronic atrophic gastritis is primarily characterized by the atrophy and reduction of gastric mucosal glands. Consequently, it often accompanies varying degrees of metaplasia in the gastrointestinal mucosal epithelium. Chronic atrophic gastritis features a reduction in B cells of the gastric glands, and the pH value of gastric juice may increase. Hence, the relationship between chronic atrophic gastritis and gastric cancer is significant, as it is considered a precancerous lesion. Therefore, if one has atrophic gastritis, it is crucial to seek timely medical treatment to prevent worsening of the condition.
How is thyroid cancer caused?
The causes of thyroid cancer are similar to those of most other malignancies. The etiology of thyroid cancer is not yet clear, but some factors are found to be associated with its occurrence: The first is neck radiation. The thyroid is an endocrine organ, sensitive to radiation. Radiation exposure can potentially cause thyroid cells to become cancerous, especially in those who received high doses of neck radiation in childhood and are more susceptible to thyroid cancer. The second factor is genetics; some thyroid cancers have a clear genetic predisposition, the most typical being medullary thyroid cancer. The third point is that the rapid increase in the incidence rate of thyroid cancer is partly due to the advancement in early diagnostic techniques, allowing for the detection of many early-stage lesions. Of course, iodine intake has already been shown to be related to some benign thyroid conditions. However, its relationship with thyroid cancer requires further study.
How long can one live with lung cancer?
The survival period of malignant tumors is a topic of great concern to everyone. The question of how long one can live with lung cancer is very difficult to answer. It should be based on the patient's physical condition and the pathological staging. However, these judgments are only based on a predictive basis and do not determine how long the patient can live. If the patient does not relapse after surgery, is sensitive to radiotherapy and chemotherapy, and shows no signs of recurrence or resistance, then their five-year survival rate is naturally higher. If the patient experiences recurrence and metastasis after surgery, then the five-year survival rate is naturally lower. Therefore, the question of how long a person can live with a malignant tumor cannot be answered generically.
Early-stage breast cancer symptoms
Early-stage breast cancer may exhibit several symptoms. The first is the presence of breast lumps. The second symptom might be nipple discharge, which can be serous, watery, or milky in nature. The third symptom might involve changes in the skin over the breast tumor, including skin adhesion, such as dimpling, engorgement of superficial veins, skin reddening, localized increase in temperature, and an orange-peel texture. The fourth symptom includes abnormalities of the nipple and areola, potentially featuring nipple retraction, erosion of the nipple, thickening of the nipple epithelium, and reddening. The fifth symptom could be breast pain.
How to check for lung cancer?
How to check for lung cancer, firstly, for lung cancer screening, particularly in people over forty years old, especially smokers, it is recommended to regularly undergo low-dose spiral CT scans of the chest. Secondly, if a tumor is detected, it is suggested to proceed with enhanced CT scans, sputum cytology tests, or PET-CT. If it is confirmed that there is a tumor in the lungs, then a biopsy is needed. The biopsy can be performed under bronchoscopy, or transthoracic lung puncture and biopsy of living tissue can also be done, as well as biopsy of metastatic lesions or cytological examination of pleural effusion to diagnose whether it is lung cancer, the type of lung cancer, and certain immunohistochemical situations.
What are the early symptoms of kidney cancer?
Many cases of kidney cancer often have no obvious symptoms in their early stages and are not discovered until the tumor progresses. After the tumor progresses, symptoms may include hematuria, which can be intermittent, painless, and visible throughout its course. There may also be back pain and a lump in the abdomen, which is evident in about twenty percent of cases. Slim individuals might find it easier to detect such lumps. There are also some extrarenal manifestations including fever, weight loss, accelerated erythrocyte sedimentation rate, anemia, hypertension, polycythemia, hypercalcemia, liver function impairment, etc. These symptoms might appear in the early stages. However, symptoms can vary from person to person.
What tests are conducted for lung cancer?
Diagnosis of Lung Cancer: The first method can be through chest X-ray and CT scan; The second is sputum cytology examination; The third involves using a bronchoscopy; The fourth is mediastinoscopy, which allows direct observation of the enlargement of lymph nodes on both sides of the mediastinum; The fifth is to perform PET-CT, which is Positron Emission Tomography-Computed Tomography; The sixth requires a biopsy; it can be done through a transthoracic needle biopsy, or via a bronchoscopic biopsy; The seventh is the biopsy of metastatic lesions, such as subclavian lymph nodes, and lymph node metastases in the neck or axillary areas can be examined; The eighth can involve drawing cancerous pleural effusion; if there is pleural effusion, pleural fluid cytology examination can be performed; The ninth method is thoracotomy exploration; if lung nodules or lung tumors cannot be definitively diagnosed through various other methods, thoracotomy exploration can be performed.
Staging of cervical cancer
The clinical staging of cervical cancer mainly uses the FIGO system, which adopts the staging criteria of the International Federation of Gynecology and Obstetrics (FIGO). Staging should be performed before treatment, and once done it does not change after treatment. Since FIGO staging of cervical cancer primarily relies on pelvic examination, it emphasizes the necessity of this examination being conducted by two experienced gynecologic oncologists. If needed, a pelvic examination under anesthesia is performed to ensure the accuracy of the evaluation. So, how is the staging performed? It involves measuring the size of the cervical lesion, particularly the measurement of endophytic tumors, the infiltration of cervical tissue, and the status of pelvic lymph nodes, providing accurate information with the aid of radiological data, especially magnetic resonance imaging (MRI).
Cervical cancer screening
For the examination of cervical cancer, it should be based on medical history and clinical manifestations, especially for people with contact vaginal bleeding, a detailed general examination and gynecological examination should be conducted, and an examination of cervical biopsy tissue is needed for diagnosis. What specific examinations are there? There are cervical scrape cytology tests, iodine tests, colposcopy, examination of cervical and cervical canal tissue, as well as post-surgical cervical conization, and examination of postoperative specimens. Therefore, there are indeed many examinations, including some radiological assessments such as enhanced CT, PADCT, MRI, and other such tests.
Does lung cancer cause coughing?
The most common symptoms of lung cancer patients include coughing, followed by coughing up blood, difficulty breathing, and chest pain. When the tumor grows in larger bronchi, it often causes an irritable cough, which can easily be mistaken for a cold. As the tumor continues to grow and affects the drainage of the bronchi, secondary lung infections can occur, possibly producing purulent sputum and an increased amount of coughed-up sputum. At this time, coughing becomes quite severe. Another symptom that may appear is blood in the sputum, which could be blood-streaked sputum, or sporadic, small amounts of coughed-up blood.
