What's the average age for lung cancer?

My boyfriend's grandma was just diagnosed with lung cancer at age 90 how long does she have left?

• At age 90 with no treatment (I'm assuming it's advanced since there is fluid collected around the lung) she also has shortness of breath and can't walk very far. With these factors honestly how long can she expect to live. She also has fluid around her lung we don't know if the fluid is malagnint because she's on coumadin for 2 strokes last year so they won't do any biopsies period. She had a chest x ray last year that was clean. Then the shortness of breath and the November 2011 x ray showed the mass and ct scan confirmed it. She coughs, has the fluid around lung, shortness of breath with all that information can someone give me an honest answer I mean is it less advanced because her chest x ray was clean last year? The family went through a terrible ordeal this time 5 years ago with the death of her husband and I don't want to see that type of thing happen again..Thanks for HONEST answers only.

• Answer:

  no one can really give you an answer to this on the internet. the doctor should have given the family some information regarding this. one thing i can tell you that if they have suggested putting her on hospice care, they dont expect her to live past 6 months. that doesnt mean she wont live past 6 months, but in order to be placed on hospice a dr has to sign that his/her professional opinion is that she will not live longer than 6 months. ive seen some people on hospice for longer than 2 years.
