Can early-stage bladder cancer be cured?
Bladder cancer is a relatively common malignant tumor in the urinary system and tends to occur more frequently in males, with the incidence rate being three to four times higher than that in females. Painless hematuria is likely to be caused by bladder cancer. Therefore, it is crucial to be cautious when hematuria occurs and to seek medical examination at a hospital as soon as possible, such as urinalysis and bladder ultrasound exams, which are non-invasive and relatively inexpensive. Early-stage bladder cancer can potentially be cured, especially if it is superficial. However, patients with poorly differentiated and highly malignant forms may undergo infusion chemotherapy and immunotherapy. Studies have shown that patients with minor bladder cancer, after undergoing systematic treatment, have a relatively high five-year survival rate.
What foods should not be eaten with lung cancer?
Lung cancer patients definitely should not smoke. Many lung cancer cases are caused by smoking, and if a patient quits smoking after the onset of the disease, their prognosis is much better compared to those who continue smoking. Additionally, there is advice to avoid certain so-called trigger foods. For cancer patients, the recommended meats are fish and poultry. This recommendation is not really due to the issue of trigger foods but because fish and poultry are easier to digest and absorb. During cancer treatment, the tumor itself causes a significant breakdown of proteins in the body. Since proteins are a fundamental basis for bodily functions, without them, human survival would be nearly impossible. Therefore, it is essential to replenish proteins. The main sources of protein include meat, eggs, dairy products, soy products, and nuts, which are all crucial sources of protein.
Late-stage symptoms of esophageal cancer
What are the symptoms of late-stage esophageal cancer? Because in the early stages of esophageal cancer, the symptoms are often not very obvious, which leads many people to overlook them. By the time they feel very uncomfortable and seek medical advice, the cancer is generally in the middle to late stages. One common symptom in the later stages is progressive difficulty swallowing, which is a main symptom presented by many patients at the time of consultation. However, this symptom generally occurs only when about two-thirds of the esophagus's circumference has been infiltrated by the tumor, making swallowing difficulties a late-stage symptom. Other symptoms of late-stage esophageal cancer include hoarseness if the tumor compresses the recurrent laryngeal nerve, belching if it invades the diaphragmatic nerves, and symptoms like breathing difficulties and coughing if it compresses the airway.
Esophageal cancer symptoms
In fact, the early symptoms of esophageal cancer are not very obvious. Some people only experience a slight discomfort when swallowing, and others might feel mild pain behind the sternum. However, in the advanced stages, the symptoms become more noticeable, such as progressive difficulty swallowing. Additionally, if the tumor compresses the laryngeal nerve, it can cause hoarseness. If it compresses the trachea, symptoms like shortness of breath and dry cough can occur. If the tumor erodes into the aorta, it can lead to severe bleeding.
Is esophageal cancer prone to bone metastasis?
Modes of spread and metastasis of esophageal cancer. In the early to mid-stages, the spread is mainly intramural, as the esophagus lacks a serosal layer, making it easy to directly invade adjacent organs. Lymphatic metastasis is also a major route of spread for esophageal cancer. In advanced stages, the cancer metastasizes through the bloodstream to the liver, lungs, kidneys, and even bones. In cases of bone metastasis, treatment options such as chemotherapy, radiotherapy, and anti-bone metastasis treatment can be chosen based on the patient's general condition. If the patient experiences significant pain, pain relief medication can be chosen according to the three-step ladder for cancer pain treatment to alleviate symptoms.
Causes of Lung Cancer
The most common cause of lung cancer is smoking, but many people who have never smoked also develop lung cancer. One possible reason could be related to kitchen fumes. Chinese cooking habits often involve high-temperature frying and stir-frying. After frying in hot oil, the higher the temperature, the more harmful substances are in the fumes, which over time could lead to lung cancer. Some patients develop lung cancer due to air pollution; secondhand smoke is also a significant cause. For example, if a husband smokes, the likelihood of his wife developing lung cancer is more than 200% higher than in the general population, indicating that smoking harms not only the smoker but also their nearest and dearest family members. Additionally, there are other potential causes including psychosomatic factors such as chronic insomnia, depression, decreased immunity, genetic factors, and more.
