Hello Nan. My husband was a Vietnam Vet. He was in the Navy --- so not on shore. He did get cancer. Perhaps tied to the ship building he was
involve in . They were aboard with lots of aspestos exposure in the shipyard. He was part of the first crew aboard 2 ships being built, The commissioning crew
for the USS Jesse L. Brown and the USS Virginia. His cancer spread fast.
Keep us posted on how your husband is doing. I know this is a very stressful time.
Is he seeing an Oncologist ? I don't know what kind of diet you are following. They say sugar helps cancer grow faster.
To heal at all I wound think you would need a healthy diet with protein and vegetables and fruit.
Keep us posted.
