Does early stage small cell lung cancer cause muscle loss and malabsorption or are these later symptoms?
Lung cancer cachexia: Muscle wasting and weight loss ("cancer cachexia") are usually late stage occurrences; malabsorption is usually not the cause of these signs, but rather "hormones" released from the tumor cause a hyper metabolic state and also contribute to poor appetite. If you are already experiencing these problems, however, it is possible that the tumor - although localized (stage 1) is unusually active. ...Read more

Can small cell lung cancer cause malabsorption through zolinger Ellison syndrome. Would this be a presenting sign of sclc before it shows on ct scan?
Uncommon: Most Zollinger-Ellison / gastrinoma are from islet cell tumors of the foregut. Oat cell carcinoma can produce other paraneoplastic syndromes, famously the anti-nerve cell ones, before being visible on chest ray, but it announces itself fast enough. And what are you going to without a localized tumor? Take out both lungs? Look for some other cause for any suggestive symptoms. Good question Gill. ...Read more
Does early stage small cell lung cancer cause vitamin deficiencies through malabsorption? Would it be seen on CT at this point?
Two issues: Early stage small cell lung cancer does not cause malabsorption. Detection with CT would depend on the size and location of the lesion. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more
Could metabolic activty from early small cell lung cancer cause vitamin deficincies (B12,D, Zinc, follate)? &Would this earlry tumor show on CT?
No; but poor diet ca: Vitamin deficiencies (more than 1) like those of which you speak come from a poor diet that often includes alcohol or cigarettes.

My husband is undergoing chemo/avastin for stage 4 non small cell lung cancer. Dr stopped chemo after 6 cycles cause weight loss. Is this risky?
There is not: Small cell lung cancer is divided into limited and extensive stage. The usual stage i-iv cancer staging system is not used. Limited stage means that all sites of cancer can be focused in a radiation treatment field. If this is not the case, it is extensive stage. http://www.cancer.org/cancer/lungcancer-smallcell/detailedguide/small-cell-lung-cancer-staging. ...Read moreSee 2 more doctor answers
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
