How is lung cancer detected?
For lung cancer detection, it is recommended for individuals over forty, especially smokers, to undergo a low-dose spiral CT for screening. Secondly, if someone has been a long-term heavy smoker and has undergone chest X-rays and low-dose spiral CT and a lung mass is found, it is suggested that the patient undergo a contrast-enhanced CT or a PET-CT to determine the condition and location of the lung mass. After establishing the condition and location, a sputum cytology test can be conducted. Thirdly, to confirm whether it is lung cancer, one should undergo bronchoscopy to obtain a biopsy, or a transthoracic lung puncture biopsy, or examine live tissue or metastatic lesions, or perform a pleural fluid examination to detect the cancer cells and determine the specific type of lung cancer to guide treatment. However, if the nature of the lesion cannot be clearly determined through mediastinoscopy, bronchoscopy, chest wall puncture biopsy, or other methods, a thoracotomy exploration is recommended. Additionally, the examination of tumor markers cannot be ignored.
Is rectal cancer without metastasis curable?
Can rectal cancer without metastases be treated successfully? If rectal cancer has not metastasized, its prognosis and outcome are relatively much better compared to cases where there are metastases and recurrences. If surgery is performed for rectal cancer and there is no recurrence or metastasis afterwards, then the five-year survival rate is naturally higher. However, if rectal cancer is initially treated surgically and cleaned thoroughly but then quickly recurs, with liver metastases, lung metastases, etc., then the five-year survival rate would be much lower. Therefore, if rectal cancer has not metastasized, the treatment and prognosis are much better. Thus, if there is no liver or lung metastasis in rectal cancer, the treatment is relatively easier.
Does rectal cancer require chemotherapy?
The question of whether chemotherapy is necessary for rectal cancer needs to be analyzed specifically, taking into account factors such as the patient's physical condition, pathological staging, and whether the surgery was completely successful. Chemotherapy for colorectal cancer can be divided into adjuvant chemotherapy and palliative chemotherapy for advanced colorectal cancer, and it can also serve to enhance the effects of radiotherapy. For low rectal cancer, neoadjuvant chemoradiotherapy can be administered if the tumor cannot be directly removed, followed by surgery after the treatment. If surgery is possible for rectal cancer, and there is lymph node metastasis or the pathological stage is relatively advanced, postoperative adjuvant chemotherapy can be performed. Therefore, the need for chemotherapy in cases of rectal cancer should ideally be assessed at a specialized oncology department in a hospital to provide a detailed analysis and evaluation by oncologists.
What is the best food to eat after rectal cancer surgery?
For malignant tumors and colorectal cancer, the suggested dietary recommendations after surgery include, first and foremost, consuming nutritious foods to replenish the nutrients depleted by the surgery and the tumor. It is advisable to eat more nutritional items. Secondly, after surgery for rectal cancer, it's important to avoid hard-to-digest and gas-producing foods such as beans, milk, and eggs. Thirdly, it is recommended to consume easily digestible items like soups and nutritious porridge. The fourth recommendation is to avoid spicy and irritating foods, and abstain from alcohol and smoking.
Why would someone get cervical cancer?
Why does cervical cancer occur? There are several reasons for cervical cancer: The first is infection with the human papillomavirus, also known as HPV infection, which is the fundamental cause of precancerous lesions and cervical cancer. Secondly, there are other factors; in a few cases, HPV DNA is not detected in the tumor tissue, especially among elderly patients, and it is related to early childbirth and multiple pregnancies. The third point is that cervical cancer incidence is associated with high-risk males, including those who have had penile cancer, prostate cancer, or are high-risk individuals for cervical cancer. Women who are in contact with these high-risk men are more likely to develop cervical cancer. Lastly, irregular diet and lifestyle, along with smoking and drinking, can suppress the body's immune function, potentially promoting cancer.
Early stage lung cancer symptoms
The most common early symptom of lung cancer includes coughing, coughing up blood, difficulty breathing, and chest pain. However, when the tumor grows in the larger bronchi, it often causes an irritating cough, leading many people to mistake it for a cold. Therefore, if an irritating cough occurs, it should be taken very seriously. The second point is that as the tumor continues to grow and affects the drainage of the bronchi, there is often an increase in purulent sputum, and the amount of sputum may also increase from before. The third commonly seen symptom is bloody sputum, which might be spots of blood in the sputum, streaks of blood, or intermittent small amounts of coughed-up blood. Large amounts of blood in the sputum are very rare.
Causes of Cervical Cancer
The causes of cervical cancer include: The first point is infection by the human papillomavirus (HPV), particularly persistent infection with high-risk types, which is the basic cause of precancerous lesions and cervical cancer. The second point is that DNA from HPV is not detected in the tumor tissues of a minority of cases, especially among some older patients. Epidemiology shows that early childbirth and multiparity are closely related to the occurrence of cervical cancer. With an increasing number of childbirths, the risk of cervical cancer also increases. This correlation might be due to the trauma to the cervix during childbirth and changes to the endocrine and nutritional states during pregnancy.
Colon cancer surgical methods
The surgical approach for colon cancer should be tailored based on the specific circumstances of the patient, involving a rational, comprehensive treatment strategy. The surgical principle is that early-stage cancers should undergo curative resection, while more advanced cancers should be treated with radical surgery or extended radical surgery. Once the treatment plan is determined, the choice of surgical methods should be made comprehensively based on the patient's specific conditions. For example, in the surgery of rectal cancer in the middle and lower segments, it should be considered whether to preserve the anus or perform abdominoperineal resection based on the tumor's biological characteristics, patient's age, overall health, and any concurrent diseases. It is not that there is one fixed type of surgery; the approach should be specifically tailored based on the detailed analysis of the issues at hand.
What are the symptoms of breast cancer?
The first sign of breast cancer can be a lump in the breast, where lumps might be palpable in the upper outer quadrant of the breast; the second symptom might be nipple discharge or bleeding; the third symptom might be pain in the breast; the fourth symptom might involve changes in the skin of the breast, such as the skin becoming rough and possibly developing an orange peel texture; the fifth symptom might be nipple retraction and changes in the areola.
Is a severely blocked anus a symptom of rectal cancer?
Is anal blockage a manifestation of rectal cancer? The answer could be yes, but it could also be due to hemorrhoids, or other diseases. The main common symptoms of rectal cancer include changes in bowel habits and the characteristics of the stool. There may be frequent bowel movements, diarrhea, or constipation, or alternating constipation and diarrhea, a sensation of anal heaviness, or associated with vague abdominal pain. Symptoms of abdominal pain, intestinal obstruction, and abdominal masses might also appear. When the tumor grows to a certain extent, an abdominal mass can be palpated, which might cause some compressive symptoms, possibly leading to anal blockage as one of the symptoms.
