Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

Mesothelioma biopsy says 'portions of fibrous tissue infiltrated by malignant cells forming nests. tumor cells +'ve for CK7 and calretinin. prognosis?

Mesothelioma biopsy says 'portions of fibrous tissue infiltrated by malignant cells forming nests. tumor cells +'ve for CK7 and calretinin. prognosis?

Marker not prognosis: CK7 and calretinin are used to verify that the tumor is mesothelial in origin (versus adenocarcinoma of the lung). It does not provide information about prognosis. Factors associated with pleural mesothelioma prognosis include: functional status, blood counts, histology (epithelial best vs fibrosarcomatous poorest), and tumor size (degree of involvement of pleural cavity). Several new trials. ...Read more

What percentage of extensive calcified lymph nodes in pulmonary hila, combined with bright red blood in sputum are cancerous in nature?

What percentage of extensive calcified lymph nodes in pulmonary hila, combined with bright red blood in sputum are cancerous in nature?

Very low: Cancerous nodes very seldom calcify much. In my old home in Kansas City, many (maybe most) folks had some calcium flecks from old histoplasmosis. I'm very concerned though if you're coughing up blood. That's cancer until proved otherwise, and you're entitled to have calcified nodes from some other cause. Please get it properly worked up. Best wishes. ...Read more

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
