Good for you, Seed. It is important to include visualisation. Seeing his throat area surrounded and glowing with a rich orange, pink, or green healing light could help, along with envisioning the cancer disintegrating, as you suggest. Also, visualising a sucessful outcome of his visit to the doctor.We did this with my mom and when they opened her up to remove the tumour they were astonished to find it gone! That was her second occurence of cancer. She went on to live another 20 years, cancer-FREE.
