Some here may not agree with me, but I would strongly suggest that you look not only at mainstream treatment methods but also what natural and alernative treatments have to offer.
Mainstream medicine has not had a great deal of success in the war against cancer. Despite being ignored and suppressed, nature has been there all along.
:Like others here, I once thought, as we and our doctors have all been taught for generations, that the only real medicine came in a brown prescription bottle and the only real treatments were those of mainstream medicine. After all "Just Ask Your Doctor". I was badly, badly mistaken.
When it comes to cancer, using surgery, radiation and chemo to try to cut out, burn out, or poison out the symptoms of cancer without addressing the underlying cause, or preventions, or the likely return of cancer, is to me just increidible.
To be sure, there are snake oil salesman and ineffective natural alternatives aplenty - just as their are failed mainstream methods. But the really good and legitimate natural alternatives have success rates of 90% and above for a wide range of cancers, even late stage ones. I know this from personal experience, not conjecture.
My own 85 year old uncle had a similar tumor in his lung. His oncologist was confidant that it had been caught early enough and that targeted radiation pellets would wipe it out in short order. Instead, the cancer continued to grow and to spread to other parts of his body.
Instead of opting for stronger radiation and the side effects of chemo in a race to kill the cancer before killing a major organ and the patient, he opted for the all natural protocol used by a group of several hundred people on a Yahoo health forum I host and moderate ("Oleandersoup").
Today he is cancer free and enjoying a regular round of golf daily. He is not the exception. The group is over 5 years old and everyone is still alive and well.

Don't just take my word for it. It is one of the strongest recommended cancer treatments at the highly respected CancerTutor website, as well as Natural News, The International Wellness Directory, CureZone, the Annie Appleseed Organization, etc. .

And, in the end, don't just take anyone's word for it - do your homework and check out what is available inside and outside mainstream medicine and remember that it is your own body and life and no one should make your decision for you.
Best of wishes!
