My husband was also diagnosed with stage 4 cancer at the end of May and began treatment on July 22, every two weeks. His doctor also told him the same thing regarding treatment every 2 weeks for the rest of his life. We are so ecstatic that his PET scan at the beginning of November showed a complete metabolic response to treatment—praise God for the shrinkage! The doctor was receptive to moving treatments to every three weeks since he’s responding so well, and we’ll rescan in three months. Praying you will also respond beautifully to treatment and be able to adjust your schedule soon.
