abdominal aortic aneurysm

my father has 3rd stage lung cancer, his ct scan demonstrates that there is sclerotic bony lesions involving the thoracic vertebare, and there is abdomen aortic aneurysm. is the late anyhow related to lung cancer? or is it a result from the chemotherapy? the doctor says that everything is very much ok   and nothing to be worried about it!! but am not sure about that, and i need a second opinion... please help me and respond with an advice..

regards

Hi,

What size is the aortic aneurysm? If it is greater than 5.5 cms - a surgical intervention will have to be considered because of the increased risk of impending rupture.

With 62 years of age, smoking history and male gender your father would come in the high risk category for developing an abdominal aortic aneurysm.

Lung cancer and chemotherapy are not independant risk factors for developing an aortic aneurysm of the abdominal aorta.

I hope he has stopped smoking now.

You can still continue with his chemotherapy if your oncologist thinks so.

Do let us know about his progress.
Hope this helps.
Good luck.
