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.
How is cervical cancer treated?
The principle of treating cervical cancer is mainly through surgery and radiotherapy, supplemented by chemotherapy in a comprehensive treatment plan. Treatment should be based on clinical staging, age, overall condition, and a combination of technical level and equipment conditions to formulate an appropriate treatment plan. It emphasizes the individualization of treatment and the importance of initial treatment. Not everyone will have the same treatment plan; it should vary from person to person, with specific issues analyzed individually. Surgical options include extensive hysterectomy and extensive cervical resection. If cervical cancer is staged late, it should also be treated with radiotherapy, supplemented by chemotherapy. Nowadays, there are also targeted medications and immunotherapies to consider as part of the treatment options.
What is the treatment for lung cancer?
Treatment for lung cancer should be based on the pathological staging, the pathology type, the biological behavior of the lung cancer, and individualization, taking into account the patient's cardiopulmonary function and overall systemic condition to develop a personalized treatment plan. For non-small cell lung cancer and small cell lung cancer, the treatment approaches differ significantly. Therefore, it is advisable for patients to seek treatment at specialized hospitals, under the guidance of oncology specialists. Generally, treatment options for non-small cell lung cancer include surgical resection, adjunctive chemoradiation, neoadjuvant chemoradiation, targeted therapy, and immunotherapy. For small cell lung cancer, a comprehensive treatment plan combining chemoradiation, along with prophylactic cranial irradiation and other aggressive treatments, is recommended. Each individual's situation might differ, so it is important to focus on a personalized comprehensive treatment plan rather than a one-size-fits-all approach.
Cervical cancer treatment
For the treatment of cervical cancer, it should be based on the patient's physical condition, nutritional status, pathological staging, and pathological type to develop a comprehensive treatment plan, rather than a general, single approach. The treatment principle for cervical cancer mainly involves surgery and radiotherapy, supported by a comprehensive treatment plan that includes chemotherapy. However, the treatment plan should be based on clinical staging, age, overall health, and consider the level of technology and equipment available to formulate a suitable treatment plan. It is important to focus on individualized treatment and the method of initial treatment. Therefore, each person is different, and treatments vary from person to person and disease to disease.
