As an expert in the field of oncology, I can provide you with information on the aggressiveness of kidney cancer. Kidney cancer, specifically Renal cell carcinoma (RCC), is indeed the most prevalent form of kidney cancer. The aggressiveness of kidney cancer can vary significantly depending on several factors, including the type and stage of the cancer, the patient's overall health, and the response to treatment. RCC can range from slow-growing tumors that may not cause significant problems for many years to more aggressive forms that can quickly spread (metastasize) to other parts of the body. One such aggressive form is Collecting duct RCC, which is rare and accounts for less than one percent of all kidney cancers. This type is known for its larger cell size and higher tendency to metastasize, making it more aggressive. It's important to note that not all kidney cancers are aggressive. The behavior of the cancer can be unpredictable, and some slow-growing tumors may never cause severe health problems. However, early detection and appropriate treatment are crucial for the best possible outcomes. read more >>
