healthy lung tissue. As they grow‚ “the abnormal cells can form tumors and interfere with the functioning of the lung‚ which provides oxygen to the body via the blood”. There are two major types of lung cancer‚ non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Staging lung cancer is based on whether the cancer is local or has spread from the lungs to the lymph nodes or other organs. Because the lungs are large‚ tumors can grow in them for a long time before they are found. Even when

urine output. METHOD: A 57-year-old male patient with hypertension and hyperglycemia was referred to our hospital because of a diagnosis regarding his left adrenal tumor. Because the levels of urinary metanephrine and normetanephrine were elevated‚ and 131I-MIBG scintigraphy showed intense uptake in the adrenal tumor‚ the tumor was diagnosed as a pheo- chromocytoma. An adrenalectomy was carried out. Severe polyuria‚ which was accompanied by a rapid decrease in central venous pressure‚ started

what lung cancer is‚ the types‚ risk factors‚ symptoms‚ diagnoses‚ and treatments. Lung cancer is uncontrolled abnormal cell growth in the lungs. The abnormal cells do not carry out the normal functions of a healthy cell. As they grow‚ tumors can grow which can further obstruct the function of the lungs. Many different cells make up the lungs. The majority of the cells are epithelial cells which line the airways and produce mucus‚ which lubricates and protects the lung (ASCO Cancer Foundation)

Calculus is used in medicine to measure the blood flow‚ cardiac output‚ tumor growth and determination of population genetics among many other applications in both biology and medicine. Although sometimes less obvious than others‚ Calculus is always being used. One of the clearest examples of the application of calculus in

The capacity of p53 for multiple biological functions can be attributed to its ability to act as a sequence-specific

Moreover‚ carcinogenesis of N-nitrosamines differs from that of N-nitrosamides in that N-nitrosamides induce regional and systemic tumors whereas N-nitrosamines only induce systemic tumors which occur far away from the place of application (Tricker & Preussmann 1990). However‚ according to DNA studies‚ tumors were found only in some organs where methylated DNA was recognized. This indicates that cancerous cells cannot be initiated by DNA alkylation alone.
