My husband has had 2 xrays and 1cat scan with contrast, the Dr's are pretty positive he has lung cancer in 2 spots. Largest is 1 cm x 3/4 cm upper left cavity. We are putting weight on him with smoothies,  extea calories in case radiation and chemo take it,  is this correct to do?  We get a consult on Monday 5/3. We are scared of the unknowns. Thanks for reading,  terry.
