At first, bladder cancer patient Ruben E. Muñoz was given a resounding "no!" by his doctors at UC Davis Comprehensive Cancer Center when he told them about his plans to trek to Mount Everest.
The retired computer engineer from Elk Grove had always dreamed of visiting Mount Everest, located in the Himalaya mountain range between Nepal and Tibet. Rising 29,000 feet into the atmosphere, it is the tallest point on Earth. More than 300 people have died attempting to climb its treacherous terrain.
"I told my doctors that the trek was not to the peak, but to the base camp of Mount Everest, which rests at 18,000 feet, but that didn't seem to change their minds," Muñoz said. "I was in treatment for stage 4 bladder cancer, and they thought I was crazy. Family and friends expressed the same level of concern. I told everyone, 'Then send me to a psychiatrist because I'm going!'"
When it appeared obvious that the 68-year-old Muñoz was not backing off his plans, his oncologist, Mamta Parikh, and other doctors decided that if they couldn't stop him from trekking to Mount Everest, they would do all they could to support him and make sure that he survived the trip.
There were some hitches along the way.
“As Mr. Muñoz had a remarkable response to clinical trial therapy initially, we kept having the conversation about when the hike might become a reality,” Parikh said. “Unfortunately, when he had to discontinue the trial treatment due to side effects, the cancer spread, again, and he had to delay the trip so he could try a second immunotherapy combination.”
Quest to Mount Everest continued
Muñoz never gave up hope that he could make the journey to Mount Everest and his positive spirit prevailed. The second immunotherapy treatment brought his bladder cancer under control. As his cancer retreated, his plans for the hike advanced. Family and friends supported him with positive thoughts and prayers, and his doctors helped prepare him for the trek.
“While he knew the risks, he felt this was his chance,” Parikh said. “To support him as best as I could, we set up hydration appointments for him and paused treatment a few weeks before his planned trip. We also sent some steroids with him just in case he developed side effects while he was hiking."
Cardiology resident Colin McNamara also ordered an altitude test to check his tolerance for reduced oxygen at high elevations, prescribed medication for altitude sickness and other medicine to control cholesterol levels to prevent a heart attack. UC Davis Health pediatrician and personal friend Erik Orlando Fernandez y Garcia also rallied behind Muñoz to help him get ready for the trip.
Showing gratitude with a UC Davis Health flag
Muñoz had one more request for his doctors. He wanted a UC Davis Health flag to take with him to Mount Everest. His doctors came through for him, working with the UC Davis Health marketing team to create a custom flag just for the trip.
"I am so grateful for the care I've received. The trip to Mount Everest would never have happened if not for my medical team, and I wanted to make sure a part of UC Davis Health came with me," Muñoz explained.
Most of the time, he draped the flag across his shoulders and back as he hiked. Sometimes, though, the flag took center stage in group photos with sherpas (Tibetan mountain guides) and other hikers Muñoz met along the way. The flag also found its way onto giant boulders and became part of the foreground in many views of Mount Everest's stunning snow-capped peak.
"When Mr. Muñoz sent us the picture of the UC Davis flag at Everest Base Camp, it was truly moving," Parikh said.
Not only did Muñoz complete the trip, but he felt immense joy during the adventure and physically felt wonderful.
"It was an awesome experience," he said. "My body handled the change of altitude in an amazing way and I was able to enjoy the trek from beginning to end."
A hardy soul with a passion for taking on big dreams
"Personally, I always believe we need to continue enjoying our lives even with the adversity of life-changing experiences like cancer," Muñoz said.
He is not one to shy away from challenges or ignore his ambitions. Always athletic, by the time he was in his teens, he was a track and soccer star in his native country of Peru. He wanted to explore beyond his hometown of Lima and decided to follow his dreams of life in the United States, emigrating when he was 23.
"I wanted to leave Peru to complete my college education, participate in college sports, and get reunited with my family," he explained. "My parents, Christian ministers, were already living in this country. I thank them for teaching me the power of prayer and [about] having faith in God."
Muñoz enrolled in California State University, Sacramento, pursuing the burgeoning field of computer science in the late ’80s. He took on another challenge 20 years later. California was opening the first competitive market for electricity in the country, based on an electronic marketplace that traded energy. Muñoz became one of the architects of the early computer infrastructure of the California Independent System Operator (Cal ISO), which maintains reliability for most of the statewide power grid.
"Stress is something that came with the job," Muñoz said. "One way to relieve the stress was to form a hiking group with friends at the Cal ISO."
It was the Fight or Flight hiking group, made up of eight friends (two women and six men) who put together the trek to Mount Everest base camp.
"We called it 'Team Fight or Flight Road Trip to Everest' because when I was diagnosed with bladder cancer in 2019 hiking became harder. We trained on Auburn and Tahoe trails, and I'd feel sick for the first 15 minutes of the hike, and then shift into what I called 'Fight or Flight' and feel great," Muñoz said.
Two years after his diagnosis, Muñoz retired from the Cal ISO but continued to hike with his former colleagues — and get ready for the experience of a lifetime: the Mount Everest hike, which took place in October 2023.
An unequalled experience
Generally, hiking to the first base camp at the foot of Mount Everest requires sound physical and mental fitness due to its high altitude, steep trails, and harsh weather conditions. Even the most fit individuals are urged to boost their stamina before the trip.
Each day on the climb brought new challenges and scenery. And each day brought Muñoz new joys and an understanding of how people lived in the surrounding environment. Muñoz said keys to success on the trip included good nighttime rest, adequate hydration, pacing yourself well, and doing what the group's guide called 'walking the mountain."
Muñoz explained. "That means to make the same effort on every step, going uphill, downhill, or on a flat surface, just like the natives do."
Camaraderie among hikers meeting on the trail also was important. Muñoz said the sense of a shared goal, among everyone in the quest together, allowed people to connect with each other on a much deeper level than people who might meet elsewhere or under different circumstances.
Returning home
"At the end of the day, we are here to serve our patients and, whenever possible, help them meet goals which are meaningful to them," Parikh said. "When Mr. Muñoz returned, we were so relieved to find on his most recent scans that his cancer remains under control."
Muñoz is continuing to hike with his Cal ISO friends, as well as to play and coach soccer.
"I believe you don't stop living just because you have cancer," Muñoz said. "I told my doctors I'd rather live a whole year fully, doing activities I enjoy, than live 10 years in a bed."
