In their early stages, patients with 肾癌 are usually asymptomatic (no symptoms or signs), resulting in most being diagnosed in their advanced stages or during an incidental finding when they undergo evaluation for another medical concern. However, some signs and symptoms may be seen as the tumour develops.

Here are some of the 肾癌症状 that may hint toward a diagnosis of this condition:

• 疲劳
• Anaemia
• 尿血
• Abdominal and loin pain
• A sensation of a mass in the abdomen
• 食欲不振
• Unintentional weight loss
• Night sweats

Most patients with kidney cancer can be treated effectively with surgery if they present in their early stages. Therefore, it is important to seek medical attention from a urologist if you notice any signs or symptoms that may hint towards a kidney cancer diagnosis, such as haematuria, loss of appetite, unintentional weight loss or anaemia.

While surgery is the primary 肾癌治疗 in most cases, some may need a combination of other treatment modalities, including targeted therapy and immunotherapy. Surgery entails removing the entire tumour, which may be done through the conventional open surgery technique or laparoscopic surgery. Furthermore, some may even be offered the option of undergoing 机器人手术 if deemed suitable. Relative to open surgeries, robotic urologic surgery provides multiple benefits such as less postoperative pain, a speedier recovery and less noticeable scars.

Kidney cancer in Singapore accounts for 1-2% of all cancers and is one of the 10th most common cancers in men. Globally, according to the American Kidney Cancer Society, the 5-year survival rate for localised kidney cancer is around 93%, with a 72% rate for regional cancers and a 15% rate for distant kidney cancers. Kidney cancer is more prevalent in men than women and is commonly found in elderly patients, where approximately two-thirds of those diagnosed are above age 65. With the rise of the use of imaging techniques, such as ultrasound scans (USS) and computed tomography scans (CT), the prevalence of this condition has shown to increase at a rate of around 2-3% each year.

Yes. If malignant kidney cancer is not treated or the condition goes undetected, it has the potential to be life-threatening. While some can be aggressive and spread to other organs, a good prognosis can be expected if prompt 肾癌治疗 is provided in the early stages.

The most common 肾癌 在新加坡 is renal cell carcinoma (RCC), and it accounts for about 85-90% of all diagnosed cases worldwide. Benign (non-cancerous) kidney tumours, on the other hand, aren’t usually fatal as they do not spread to other parts of the body. These tumours 可能 be removed surgically, if they are causing symptoms, such as bleeding or are causing issues to the normal function of the kidney.

The rate at which kidney cancer spreads will depend on a number of factors, including the type, size, extent, and grade of the cancer. Usually, larger and higher-grade tumours tend to be more aggressive and are more likely to metastasise (spread) to other organs, while low-grade tumours are more slow-growing.

According to the World Journal of Oncology, the most common and aggressive form of renal cell carcinoma is the clear cell subtype, and about 70% of kidney cancers are composed of these cells. Renal oncocytoma (a noncancerous kidney tumour), on the other hand, is not aggressive, grows rather slowly and does not metastasise .

Overall, the rate of spread will vary depending on the type of kidney cancer, making medical evaluation an important facet for an enhanced outcome. Therefore, it is essential that you consult a reliable and experienced medical professional for a thorough assessment like Dr Terence Lim, who is a 泌尿外科高级顾问 as well as the Medical Director at Assure 泌尿外科和机器人中心. With a subspeciality in Uro-Oncology (urological cancers) and experience in doing over 700 robotic surgeries, he is well versed in providing expert treatment for kidney cancer.
