Kidney Cancer Cases Rise in Young Adults, Experts Baffled

A sharp and unexpected increase in kidney cancer cases among adults under 50 is baffling medical experts, despite known risk factors like obesity and high blood pressure.

Rob Houliston, a 33-year-old rugby player, experienced an achy back that he initially dismissed as a sports injury. Over several months, his condition worsened, leading to significant weight loss and nausea. A freak accident involving a dog resulted in a swollen testicle, which prompted an ultrasound. During this examination, doctors discovered a varicocele, a swollen vein that can indicate kidney issues. Further tests revealed a large tumor on Houliston's kidney.

He was diagnosed with renal cell carcinoma, the most common form of kidney cancer, and given an average life expectancy of four years. "Four years is not long, but I'm not going to give up," Houliston stated. "It is what it is. There's nothing I can do but crack on, be positive, and fight it."

Kidney cancer is the sixth most common cancer in the UK, with nearly 14,000 diagnoses and approximately 4,700 deaths annually. Recent studies indicate a significant rise in early-onset cases, particularly among those under 50. One study examining four decades of data found a 157% increase in incidence among men under 50 and a 133% increase in women under 50.

While experts link the trend to rising obesity, high blood pressure, and smoking rates, they remain perplexed by the increase in cases among fit and healthy young individuals. A major challenge with kidney cancer is that early stages (one and two) are often symptom-free, with no warning signs unless detected during unrelated investigations.

Houliston's tumor was pressing on his stomach, explaining his appetite loss and nausea. His kidney and the tumor were surgically removed in July. He is scheduled to begin immunotherapy, a treatment that uses the body's immune system to fight cancer cells, on September 29.

"There have been cases where people in their 80s have survived ten years with this - I'm strong and quite young, so there's no reason I can't do better than that," Houliston said. He hopes immunotherapy can shrink or eliminate his tumors, noting the development of new treatments.

Houliston and his family successfully raised £17,500 through a GoFundMe campaign for a trip to Disneyland, exceeding their £8,000 target within hours. He plans to return to work in October and hopes to resume playing rugby within two years. He encourages others with the illness to set goals and remain positive, while also seeking information on new treatment options.
