While this would depend on advice of his doctors and his health conditions then, Carter, 90, said a visit to Nepal later this year would require a five-week postponement of his last radiation therapy.
"I would still hope to go (to Nepal). It would require an airplane flight from Kathmandu to the Chitwan area, which is south down toward the Indian border. And if I do that, I understand from my schedule that it would require a five-week postponement of my last treatment. So that's what I'm going to have to consider," Carter told reporters.
"It's in God's hands. I'll be prepared for anything that comes," said Carter, the 39th president of the United States from 1977 to 1981, during which he also visited India.
After leaving the White House, Carter has been active in humanitarian projects in some 80 countries. He said he would continue to do the humanitarian work subject to approval of his doctors treating on him.

"The government of Israel has no desire for a two-state solution, which is the policy of all other nations in the world, and the United States has practically no influence compared to past years in either Israel or Palestine. So feel very discouraged, but that would be my number-one foreign-policy hope," he added.
Carter was awarded a Nobel Peace Prize in 2002. He helped defuse nuclear tensions in the Koreas and also helped avert a US invasion of Haiti.
