Hi, last Aug a routine ct scan showed a nodule had grown from 2mm to 8mm in 2 years. They scheduled lung surgery lobectomy of lingula, I refused as ongoing tummy issues and after being ignored and dismissed eventually a ct angiogram on my mesenteric artery showed a need for an immediate stent in SMA. Now I am better have gained some of the weight I lost, am feeling great and ready for surgery, they are refusing and saying I have to have radiotherapy.. I have no diagnosis of lung cancer, just a suspicion based on my previous smoking history. 

Im furious as they were happy to operate before my mesenteric diagnosis, despite the fact I’d lost 2 stone was vomiting regularly and in constant pain when eating or drinking. 
I do not have a cancer diagnosis .

3 years ago they told me I had bowel cancer, then 6 weeks later told me I didn’t. I had a double volvolus and lost 14 inches of colon and an ileostomy was formed and later reversed. 

A PET scan showed lots of activity in my tummy, they told me again ‘suspected’ cancer. Then after tests they cleared me to go ahead with lung surgery. I refused lung surgery as was so ill ( and being ignored) until eventually the colon surgeon said the histology indicated ischemia and ordered the ct angiogram ( but not urgently, it took a month). Within 2 weeks of the results I had a stent fitted.

How am I expected to believe a thing they say? Is it lung cancer? What will radiotherapy do to me? I’m 65 Female.
