Many people assume that serious illnesses, like cancer, come with obvious warning signs. However, kidney cancer often develops silently, showing no clear symptoms until it reaches an advanced stage. This makes it one of the most dangerous yet overlooked cancers.
Imagine feeling perfectly healthy, yet unknowingly carrying a life-threatening tumor inside you. This was the reality for Mr. T. and Ms. N., two patients who discovered kidney tumors during routine health check-ups, even though they had no unusual symptoms. Their stories highlight the importance of regular medical screenings in detecting and treating kidney cancer early.
A Hidden Danger: How Kidney Cancer Was Discovered by Chance
Case 1: Mr. T. – Diagnosed Without Any Symptoms
Mr. T. was proactive about his health and decided to undergo a full-body screening. He had no symptoms, no discomfort, and no reason to suspect anything was wrong. However, during the examination, MRI and CT scans revealed a small 2cm tumor in his left kidney.
Following this discovery, doctors at Cho Ray Hospital immediately consulted him on treatment options. The recommended approach was surgical removal of the tumor, ensuring that the cancerous cells were eliminated. The pathology results later confirmed that the tumor was a sarcoma-like carcinoma, a dangerous form of cancer. Fortunately, due to early detection, the surgery successfully removed the tumor with safe margins, preventing further complications.
Case 2: Ms. N. – A Larger Tumor, Yet No Symptoms
Similar to Mr. T., Ms. N. underwent a routine medical check-up despite experiencing no health issues. Her kidney function tests and urine tests all returned normal results. Yet, when doctors performed ultrasound and CT scans, they found a 42x40mm cystic tumor in her left kidney.

Unlike a simple kidney cyst, this tumor had polygonal edges, thick walls, and multiple septa inside, raising concerns about malignancy. Following medical advice, Ms. N. underwent surgery to remove the tumor, which was later identified as a multi-septate cystic kidney tumor with malignant potential.
Thanks to early intervention, she was able to receive proper post-operative care and medical guidance to prevent complications.
Why Kidney Cancer is Often Discovered Too Late
According to Dr. Cao Thi Hong, a specialist at Cho Ray Hospital’s HECI Center, kidney cancer is ranked 14th among all types of cancer globally and 16th in terms of mortality. In the United States, it is one of the top 10 most common cancers in both men and women, accounting for 4-5% of all cancer cases.
But why do so many cases go undetected until it’s too late?
- Lack of Symptoms – Unlike other cancers that may cause pain, lumps, or fatigue, kidney cancer can grow without causing any noticeable discomfort.
- Hidden Location – The kidneys are located deep inside the body, making small tumors difficult to detect during standard check-ups.
- No Universal Screening Test – Unlike breast cancer (mammograms) or colon cancer (colonoscopy), there is no widely recommended screening test for kidney cancer.
How Does Kidney Cancer Develop?
Kidney cancer originates in the renal cells, which line the small tubes inside the kidney responsible for filtering blood. When these cells become cancerous, they begin to grow uncontrollably, forming a tumor. If left untreated, the cancer can spread to nearby tissues, lymph nodes, or even distant organs like the lungs and bones.
Common risk factors include:
- Smoking – Increases the risk of kidney cancer by 50%.
- Obesity – Extra body fat can lead to hormonal imbalances that promote tumor growth.
- High Blood Pressure (Hypertension) – A leading contributor to kidney disease and cancer.
- Family History – Genetics play a role in developing hereditary kidney cancer syndromes.
- Chronic Kidney Disease – Long-term kidney damage increases the likelihood of cancerous cell mutations.
Why Regular Health Screenings Are Critical
Currently, there is no universal screening guideline for kidney cancer, meaning most cases are only discovered accidentally—like in the cases of Mr. T. and Ms. N. This highlights the importance of routine health check-ups, especially for individuals with high-risk factors.
Doctors strongly recommend undergoing medical screening every 6-12 months, even if you feel completely fine. A simple abdominal ultrasound or CT scan can help detect early-stage tumors before they grow large enough to cause harm.
By catching kidney cancer early, treatment success rates increase significantly, and the chances of survival improve dramatically.
How to Reduce Your Risk of Kidney Cancer
While regular screenings are essential, adopting a healthy lifestyle can also lower your risk of developing kidney cancer. Here’s what you can do:
- Quit Smoking – One of the most effective ways to reduce your risk.
- Maintain a Healthy Weight – Obesity is linked to many cancers, including kidney cancer.
- Control Blood Pressure – Regular exercise and a balanced diet help keep hypertension in check.
- Stay Hydrated – Drinking enough water supports kidney function and detoxifies the body.
- Limit Alcohol & Processed Foods – Reduce the intake of alcohol, red meat, and processed foods, which may contribute to inflammation and cancer risk.

Final Thoughts: Early Detection Saves Lives
Kidney cancer is often called the “silent disease” because it develops unnoticed until it reaches an advanced stage. However, as seen in the cases of Mr. T. and Ms. N., early detection through routine health screenings can make all the difference.
Even if you feel perfectly healthy, don’t skip your annual check-ups. A simple ultrasound or CT scan could potentially save your life by identifying hidden dangers before they become life-threatening.
