Does anyone know of alternative medicines for stage-four lung cancer?

No alternatives: Unfortunately stage IV lung cancer , with 10% 5 year survival rate , with life expectancy of 10 months, should be on proven methods, to be in that 5 % group to under go chemo radiation and not to depend on unknown unproven alternatives.

Clinical trials: There are plenty of people who are willing to sell "alternative" (i.e. Unproven and untested treatments) for many diseases including cancer. If standard therapy (i.e. The therapy with the best evidence for effectiveness) is ineffective it is best to try to get into a clinical trial where promising therapies are tried under supervision to help advance the state of care.
