A mass in the lung does raise the issue of lung cancer. It is also possible to have benign masses in the lung. Some of them may be indolent infections, and occasionally they may produce fevers, usually low grade. Some benign growths in the lung, may also cause some obstruction and produce secondary infection in the obstructed airways and produce fever as well. There are also other structures in the lung, such as lymph nodes and this may present a different kind of cancer (like lymphoma)- a curable one.
The concern for the urine would be based on the diagnosis. At the present time, you are still waiting for the biopsy. If there is a proven malignancy, then the other symptoms would be interpreted in this light. Dark colored urine may not be due to blood but to bile. This may be a symptom of a problem in the liver, which may be a site of cancer spread.
Discuss your concerns with your doctor. Some information may not have a direct bearing on big decisions about treatment, but even some things thought trivial may make a difference when presented with multiple options.
Thank you so much for the response, Dr. Heinrik. I'm glad I have some info to take back to them.
I just wanted to post an update, in case any info might help anyone else. My dad went for the needle biopsy yesterday. While doing this they discovered a lot of fluid in his lung (or maybe it was in the pleural space, I'm not sure) and after the biopsy did a thoracentesis to remove the fluid. The total fluid removed was 1.5 liters. This fluid was not there when they did the CT scan 2 weeks ago. Dad said it was pretty red but the surgeon said it was only about 5% blood. Dad said neither procedure hurt, but he was sore a couple hours after it was over, when the Novocaine wore off. He had bandaids covering the holes, but neither appeared too big and there was only a small amount of blood. He still has the pain, and fever.
We get the results on Monday. The waiting stinks. But we're all keeping our spirits and hopes up. Dad's still going to work but is taking it easy while there, and continues to golf and go to band practice. I'm proud of him.
Also, he has a rash on the right side of his back, about the size of a cookie, that the doctor asked about, how long he had it, etc. He really hadn't noticed it before, so we're not sure when he got it. It's not itchy. He turned 61 last month.
The presence of fluid around the lung is a common finding in cancer. The bloodier it is the more likely that it is due to cancer. Removing the fluid does afford some relief, but if it really is cancer, without any other treatment, odds are it would be back within the next 3 months.
Waiting for results can indeed be awful. There are preparations of the specimen that involved drying and fixing that do take time, and departures from such protocol may make the reading erroneous.
Thanks for the additional info Dr Heinrik. Well, I just heard from my dad, he discussed the results with his specialist just last hour and they didn't find any cancer cells but did find abnormal cells. So he is going to get a PET scan and a procedure (didn't get the name) where they're going to stick a scope in his side to get a better look. I was under the impression that PET scans were the be-all-end-all in cancer detection, I guess this is wrong though since they're doing another procedure in addition to it.
He meets with the new surgeon Sept 23. We are all very, very pleased with today's results, but know he still could have cancer. What are the success rates of needle biopsies? It probably depends on many factors, I would think.
