Biochemsitry major David Hess cancer free

Senior biochemistry student David Hess has been booed by 40,000 people at Fenway Park in Boston – he was pitching a bad game. This is nothing compared to the years of chemo and radiation therapy.
After David was drafted in 2014 by the Baltimore Orioles, he made his major league debut in 2018. He signed with the Tampa Bay Rays as a free agent, and when he was traded to the Miami Marlins, David and his wife moved down to Miami. David was having a good season when he gradually started to feel a bit off in 2021.

“I started having shortness of breath, my ribs were popping out of place, I had to see a chiropractor on a regular basis. I thought it could be stress or COVID.”
He started to get worse, his game started to suffer and one morning, he coughed up blood, sending him to the ER. David’s blood pressure was extremely high, so they admitted him, originally thinking the culprit was stress but still wanting to run some tests.
A Diagnosis
“They performed an x-ray and came into the room. They said ‘Do you see that big shadow over your lungs? That’s not supposed to be there.”
There was a pineapple-sized, germ cell tumor on David’s lungs. The tumor was pushing his organs around and his windpipe was at 15% capacity. The doctors were amazed that David had been playing major league baseball.
Germ cell tumors are rare. As a fetus develops, cells form in eggs in the ovaries or sperm in the testicles. Rarely, these cells travel to other parts of the body and grow into germ cell tumors. The survival rate is over 90%. However, there is a chance that there may be something lurking under the tumor that is unseen and unknown.

Nine Lives
David went through nine weeks of chemotherapy and responded well.
“I went through the treatment and the good thing about this is that germ cell tumors shrink down quickly. It went from a pineapple-sized tumor down to a baseball or softball sized-tumor quickly.”
In the winter of 2022 David went in for a follow-up scan and the tumor had grown – he feared he was falling into that 5 – 10%. They started him on a rigorous 12-week treatment plan. David stayed optimistic.

“Here we go – round 2. It’s not ideal, but let’s do this.”
On the last day of David’s 12-week chemo and radiation treatment, he suffered a seizure in the doctor’s office and stopped breathing for a short time.
“I guess I am using up some of my nine lives here,” David says laughing.
When the scans came back after the round two treatment in spring of 2023, the tumor was still present. David’s oncologist sent around the scans and biopsies to different specialists around the country and one came back with some terrible news.
“The specialist called back and said, ‘I hate to do this, but this is not a germ cell tumor – this is clear and definitive angiosarcoma,’ which is a much worse diagnosis. Where we were looking at a 95% success rate, angiosarcoma is basically the opposite.”

Angiosarcoma of the lung is a rare, aggressive tumor that usually spreads from another part of the body and originates in the vascular or lymphatic system. The specialist that diagnosed David with angiosarcoma did not have any positive feedback.
“He told me to basically get my affairs in order, it was that bad. But my oncologist and my team at Greenville did not accept that.”
Staying Strong
David truly leaned on his faith, his competitive and passionate nature and his family, particularly his wife, Devin, during these times to give him strength and hope. He also always knew the end goal was to live and to live playing baseball again.

“The idea of this beating me did not cross my mind. I am also a huge Star Wars fan so through this process I felt like Hans Solo. Never tell me the odds.”
The oncologist planned to perform a lung surgery to remove as much of the cancer as possible, then David would go on to treatment with the ultimate goal of an open-heart chest surgery to extract the chest mass out.
Since David knew he was going to be home during the treatment after the surgery, he began to get back into the groove of things. He started coaching a travel baseball team and in summer of 2023, he enrolled in the biochemistry program at Clemson University and took Physics I and II online over the summer.

“The lung surgery went really well. In fall 2023, I started in person classes at Clemson while I was still doing chemo and coaching a travel ball team – I guess I just don’t know how to not do things.”
A Miracle Scan
The chest surgery was planned for right before Thanksgiving. A few days before the surgery, David and his wife went in for the pre-operative appointment so the doctor could get scans of his chest to map out the surgery.
“He came in and he said, ‘I don’t know what to tell you, we don’t need to do the surgery. The treatment wasn’t supposed to work the way it did, and something has happened in the last week since your last scan.”

The tumor in David’s chest had shrunk enough to where they surgery’s risks outweighed the benefits, so he went straight into chemo and radiation therapy again. By the spring of 2024, David’s lungs had stayed clear, and his chest was stable. However, by finals week, he had spots on his lungs again. David’s new treatment plan was six months of rigorous chemo and radiation therapy.
“A whole summer of treatment into the fall – I ended up having to take the fall semester off. I was down for the count. We get to the end of the treatment and my chest had stayed stable and my lungs were looking good. We thought this might have just been a Hail Mary.”
Third Time’s a Charm
David had his first post-treatment scan in October it was looking like the treatment had worked. However, it takes three scans to be certain that the medicine is out of your system to know it’s not a false positive.
David’s December scan came back good.
“Well, you get one more and that’s called a streak!”

In spring 2025 David enrolled back into courses as a biochemistry major at Clemson. His passion resonates over to his academics and beyond. After his grandfather died of cancer, David has been interested in working in the medical field, giving back. He was so excited to be back in the classroom.
“My passion is not just about performing well in the classroom but also helping the people around me just as much as my own personal growth.”
The last week of February 2025 David went in for his third scan and though they still have to keep an eye on it, the scan comes back with no evidence of disease.

“As of this moment I can say that I am cancer-free! It’s been a wild ride.”
David lives in Greenville, SC with his wife, Devin and their two cats, Stripes and Penny. He is currently enrolled in the biochemistry program at Clemson University, coaching a travel ball team, running a podcast with his wife called The 41 Life, is actively training to get back on the baseball field and is living his beautiful cancer-free life, constantly looking for ways he can help others.
