According to Gould, compared to any other illness he's ever had, chemotherapy is "a lot worse."
But less than a year later, Gould's parents Tricia Petrisko and Robert Gould, say he is cancer-free and back to his normal self.
"I don't care talking about it," said Gould, but "I feel brave."
In 1994, the severe side effects from Hodgkin's chemotherapy treatments prompted Billy Best of East Bridgeport, Mass., to flee rather than finish his treatment.
"I ran away because I believe the chemo was poisoning me and it would kill me before it cured me," Best, now 31, told ABC's "Good Morning America."
Best returned and started his own alternative therapies, including roots, Indian rhubarb, slippery elm and an immune boosting concoction called "714-X," which Best credits for saving his life.
But Bostrom remains unconvinced.
"It sounds to me like he received some chemotherapy and he could have been cured with just that chemotherapy," said Bostrom, who added that doctors now have a better idea of when a cancer is cured than in 1994.
"I think his lifestyle is great, but I don't necessarily believe that's what's cured him of his Hodgkin's," said Bostrom.
Despite the controversies of people who choose natural therapies as alternatives to cancer treatment, Bostrom said he thinks it's better for doctors to discuss treatments outside the medical establishment than to dismiss them.
"In the past, a lot of physicians would say, 'don't take that crap, it's no good,'" said Bostrom, while pointing out many people still use alternative medicine.
But the National Center for Complementary and Alternative Medicine estimates that in 2007, nearly 40 percent of adults and 10 percent of children used complementary medicine.
"Whether we as physicians ignore it, we know it's important to understand it and discuss it with them," said Bostrom.
Bostrom asks each of his patients what alternative and complementary medicine they use, and how much it costs. He says he is able to weed out supplements, like vitamin C, which can interfere with chemotherapy drugs, and sometimes save his patients hundreds of dollars a month.
"Sometimes they are spending a lot of money and it's something you can find in fruits and vegetables," said Bostrom, adding that he's a big proponent of research into natural remedies for future cures.
"A good example is the chemotherapy I gave Daniel Hauser," said Bostrom. "It's a combination of seven different drugs, and five of those drugs are derived from natural products."
