Types of Lung CancerLung cancer is histologically classified into two main forms: small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC), which itself includes several subtypes (adenocarcinoma, squamous cell carcinoma, and large cell carcinoma), each having distinct clinical features and treatment approaches. SCLC accounts for approximately 15% of lung cancer cases, while NSCLC is responsible for almost 85% of lung cancer cases..symptoms of lung cancerSome common symptoms of lung cancer include: Persistent cough, lasting for at least 3 weeks (with or without coughing up blood) Unintentional weight loss (more than 5% within 6 months) Shortness of breath (dyspnea) Chest pain (due to tumor invasion of the pleura or chest wall) Bone pain (due to metastases, typically in the spine, pelvis, and long bones) Stages of the DiseaseNon-small cell lung cancer (NSCLC), the most common type of lung cancer, has five stages:   Stage 0 : Cancer is confined to the lining of the airways, has not invaded deeper tissues, and has not spread beyond the lungs.   Stage 1 : Cancer is present in the lung tissue but not in lymph nodes or other organs.   Stage 2 : Cancer has spread to nearby lymph nodes on the same side of the chest, invaded the chest wall, diaphragm, or outer lining of the lung.   Stage 3 : Cancer has spread to lymph nodes on both sides of the chest, mediastinum (the area between the lungs), or other structures in the chest such as the heart,      esophagus, or trachea.   Stage 4: Cancer has spread to distant organs such as the brain, bones, liver, or supraclavicular lymph nodes.  Small cell lung cancer (SCLC), a less common but more aggressive type of lung cancer, has two stages:    Limited stage : Cancer is confined to one lung and nearby lymph nodes on the same side of the chest.    Extensive stage : Cancer has s,lung cancer ...ادامه مطلب

Definition of DepressionDepression is a common mood disorder that affects approximately 5% of adults worldwide. This disorder leads to a continuous feeling of sadness, loss of interest in daily activities, and a decrease in motivation. It can occur due to problems in school, work, or personal life, and can lead to further difficulties in various areas. Contrary to popular belief, depression is different from normal mood and emotional changes related to everyday life and can severely impact all aspects of life, including relationships with family, friends, and society, to the extent that it may even result in suicide in severe cases. Individuals can conceal the symptoms of depression to the point where they appear happy, healthy, and normal, making it challenging to diagnose and provide appropriate treatment. Depression can affect anyone, although individuals who have experienced abuse, loss of loved ones, or other stress-inducing events are more susceptible to developing depression. It is estimated that around 7% of the global population experiences a major depressive disorder annually. However, these numbers are not very precise as many individuals suffering from depression do not seek medical help. The prevalence of depression is three times higher in individuals aged 18 to 29 compared to those over 60 years old. Additionally, women are 1.5 to 3 times more likely to experience depression than men during adolescence.Symptoms of Depression and Diagnostic CriteriaThe diagnostic stage is one of the most important steps as it determines the approach and Depression Treatment plan. The examination of depression symptoms begins by assessing changes in sleep pattes, appetite, and energy levels. At least five of the following criteria are necessary for a clinical diagnosis (one of the symptoms must be either a depressed mood or loss of interest or pleasure): Sleep disturbances Loss of interest or pleasure Feelings of guilt or worthlessness Fatigue and disrupted en,symptoms of lung cancer ...ادامه مطلب

Signs and Symptoms of Lung CancerMost lung cancers do not cause any symptoms until they have spread, but some people with early lung cancer do have symptoms. If you go to your doctor when you first notice symptoms, your cancer might be diagnosed at an earlier stage, when treatment is more likely to be effective. Most of these symptoms are more likely to be caused by something other than lung cancer. Still, if you have any of these problems, it’s important to see your doctor right away so the cause can be found and treated, if needed.Lung Cancer SymptomsSome common symptoms of lung cancer include:   Persistent cough, lasting for at least 3 weeks (with or without coughing up blood)Unintentional weight loss (more than 5% within 6 months)Shortness of breath (dyspnea)Chest pain (due to tumor invasion of the pleura or chest wall)Bone pain (due to metastases, typically in the spine, pelvis, and long bones)What are the types of lung cancer?There are many cancers that affect the lungs, but we usually use the term “lung cancer” for two main kinds: non-small cell lung cancer and small cell lung cancer. Non-small cell lung cancer (NSCLC)Non-small cell lung cancer (NSCLC) is the most common type of lung cancer. It accounts for over 80% of lung cancer cases. Common types include adenocarcinoma and squamous cell carcinoma. Adenosquamous carcinoma and sarcomatoid carcinoma are two less common types of NSCLC. Small cell lung cancer (SCLC)Small cell lung cancer (SCLC) grows more quickly and is harder to treat than NSCLC. It’s often found as a relatively small lung tumor that’s already spread to other parts of your body. Specific types of SCLC include small cell carcinoma (also called oat cell carcinoma) and combined small cell carcinoma. Other types of cancer in the lungsOther types of cancer can start in or around your lungs, including lymphomas (cancer in your lymph nodes), sarcomas (cancer in your bones or ,Lung Cancer Symptoms ...ادامه مطلب
