Can I get help understanding a medical diagnosis mother?

On behalf of my Mother and our family I hope there is someone out there who can translate the below. We're prepared for the worst but my mother can't get consultant to put it in plain English - or give her a timeframe.
Some background first:
My mother is 63. No pain. Always small/slight but in last month gone from 36kg to 34kg. Lost 1kg in last 2 weeks.
Diagnosis: Bilateral centrilobular emphysema. Right lung clear. There is a 8.3x6.3cm mass in left lower lobe containing focal area of necrosis. There is a 1.1cm subcarinal lymph node. Focal area of low attenuation within the R lobe of liver and adjacent to the falciform ligament likely focal fatty infiltration. There are subcentimeter retroperitoneal and upper abdominal lymph nodes.
Conclusion:
Large left lower lobe lung mass with necrosis is suspicious for bronchogenic carcinoma
1.1 cm subcarinal lymph node
A focal low attenuation liver lesion, likely focal fatty infiltration

Hopefully someone can be honest with us and translate.

Bronchogenic carcinoma is a cancerous tumor originating in the bronchi. Necrosis is a type of cell death in which cells swell and break open, release their contents and can damage neighboring cells and provoke inflammation, which is happening in the lungs. The Lymph node is a small oval or round gland that makes up part of the immune system that removes bacteria and foreign particles from the body. If it is at 1.1cm it can be harmful to the body as less bacteria can be removed. I'm really sorry.

Ok, this will in now way, shape or form be a diagnosis, but I can at least help you decipher some of the medical terminology.

Bilateral centrilobular emphysema - Means that she has emphysema present in her lungs (if you're looking at her lungs from top to bottom, and not from the front or back, this is what they're talking about).

Necrosis - dead tissue (necro = dead)

Bronchogenic carcinoma - lung tumor (malign - this means it's the "bad", or "spreading" form of cancer, while benign is "good", or just a mass, but non spreading... That's a very simple explanation, but I hope it sort of clarifies this.)

... What it sounds like to me, is that they suspect lung cancer in the lower part of her left lung, especially if that is where the necrosis is present. They're looking at lymph node involvement to see if the suspected cancer has metastasized (or spread) to her lymph nodes (which, if it has, could be bad, since the lymph system spreads throughout the entire body).

I really wish I had more detail on why they're looking at her liver. With the "focal fatty infiltration" of the liver, that is a benign occurrence - but it can be confused with a malignant presence.

In all honesty, I would be more concerned with the mass in her lung.

As it is, if the doctor she has now isn't putting this into "plain English" for you, it's time for another doctor.

I wish you, and your mother, all the best... and if you need any more help, feel free to email me. I'm currently studying to become an MD, so I can ask some of my Professors for their opinion on this diagnosis, if you'd like. ;o)
