Adenocarcinoma with bac features stage 1V, treatment questions - 1272944

I was dx in May of last year with Adeno with bac features-lepidic predominance 80% with acinar and papillary pattern consistent with previously named Bronchoalveolar carcinoma.I have had scans every three months and the last one was this past week. I have had no changes in my scans.The last two months my breathing, SOB has been worse so i"m a bit confused but happy with latest ct scan. My onco mentioned to me that it is hard to see my cancer because they consist of cloudy looking densities instead of solid tumors. She said this type of cancer is very slow growing, sometimes not really changing much in months, to several years and most always stays confined in the lungs. I have had no treatments as of yet because of the lack of growth that they can see. The largest area that she showed me is 2.5x1.6 cm of soft tissue density in my right lung. Does anyone has this same cancer and are you receiving treatment ? I read my report from my dec ct scan and it read that in my right lower lobe their is a cystic opacity 4.3 cm in size. Isn't that considered growth or is a cystic opacity different? She told me that is very difficult to measure my cancer in size because the cancer grows kind of like vines around your vessels. Does this make sense to any of you? So confused! I'm hoping that someone has the same type to give me some insight on my cancer and what to except down the road. Thank you so much for listening and prayers for everyone continuing to fight. Donna
