What are pulmonary nodules? My step dad was diagnoised with Pulmonary nodules, but told they are the non-cancerous type.  I'm looking for more information about this and what he may be looking toward relating to possible removal what are the risks?  Is this common?  How serious are is this?

This has caused his heart to race- his bpm is at times 180, as I understand this is totally abnormal.

Anyone who can direct me to a website on this besides the webmd or mayoclinic or has any information, it would greatly be apperciated by our family.

And yes he is going to a cardiologist soon, but he is on medicare and I'm concerned with the level of care he will receive as he is also in his late 50's and as I understand not really looked at as #1 for great help.
  Thank you for your time and assistance!
  Happy Holidays to you all!
