I have been suffering from lung adenocarcinoma for 9 years. In June 2018, the review found that the original pulmonary nodules were enlarged, which may have recur. In September, I introduced the role of hydrogen absorption through other comrades in the light of life association. TC was reduced by 1.1×1.2 after 1 month after the original 1.2×1.4 hydrogen absorption. So have confidence to absorb hydrogen good, rented hydrogen machine to go home to continue to absorb later.
