According to the World Health Organisation (WHO) and the International Agency for Research on Cancer (IARC), <\/span>kidney cancer ranks <\/span>\u200b<\/span>\u200b<\/span><\/span>14th among the most common cancers worldwide, with an estimated 434,840 new cases annually. While early-stage <\/span>kidney cancer may not show symptoms, early detection significantly improves treatment outcomes.<\/span>\u00a0<\/span><\/p>\n Kidney cancer occurs when abnormal kidney cells grow uncontrollably, forming a tumour. The most prevalent <\/span>kidney cancer in adults is Renal Cell Carcinoma (RCC), making up around <\/span>\u200b<\/span>\u200b<\/span><\/span>85% of cases as per the Journal of Kidney Cancer and VHL. Less common types include transitional cell carcinoma and Wilms tumour, which mainly affects children.<\/span>\u00a0<\/span><\/p>\n The exact <\/span>kidney cancer causes are unclear, but various risk factors raise the chances of developing:<\/span><\/p>\n \u00a0<\/span><\/p>\n Early <\/span>kidney cancer often doesn’t show apparent symptoms. However, as the tumour grows, certain <\/span>signs and symptoms of kidney cancer may appear. Here’s a closer look at the common <\/span>symptoms of kidney cancer:<\/span><\/p>\n \u00a0<\/span><\/p>\n One of the most common signs of <\/span>kidney cancer is blood in the urine (haematuria). Urine may appear pink, red, or brown, though blood is sometimes invisible to the eye and only detectable through a urine test. Blood in the urine occurs because the tumour grows inside or near a blood vessel, which can bleed into the urine.<\/span><\/p>\n \u00a0<\/span>\u00a0<\/span><\/p>\n Individuals with <\/span>kidney cancer may experience dull or persistent pain in the side or lower back, where the kidneys are located. The pain might not always be sharp or intense, but it can be uncomfortable or constant. This pain is often associated with the tumour pressing on surrounding organs, muscles, or nerves. As the tumour grows, it can cause more significant discomfort and may even radiate to the abdomen or other areas of the body.<\/span>\u00a0<\/span><\/p>\n <\/p>\n Fatigue often arises due to the body fighting off cancer, but it can also result from anaemia, which is a common complication of <\/span>kidney cancer. Anaemia happens when the body lacks sufficient healthy red blood cells (RBCs) to supply oxygen to tissues, leaving the individual feeling weak, pale, and tired.\u00a0<\/span><\/p>\n \u00a0<\/span><\/p>\n In some cases, the kidneys become unable to properly filter waste and excess fluid, leading to fluid buildup in the legs, ankles, or feet. This swelling, also known as oedema, often comes with a sense of heaviness or tightness in the affected areas. <\/span>Kidney cancer causes changes in the body’s protein levels, further contributing to fluid retention.<\/span><\/p>\n \u00a0<\/span><\/p>\n Kidneys help regulate blood pressure by maintaining the balance of sodium and fluids in the body. When kidney function is impaired by cancer, it can lead to an increase in blood pressure. Sometimes, blood pressure medications might not be effective in controlling hypertension caused by <\/span>kidney cancer.<\/span><\/p>\n \u00a0<\/span><\/p>\n Fever may be caused by the body’s immune response to the tumour. In some cases, <\/span>kidney cancer can lead to infections, abscesses, or other complications that can result in fever. Fever accompanied by other symptoms like unexplained weight loss or fatigue may point toward a more serious underlying issue.<\/span>\u00a0<\/span><\/p>\n <\/p>\n Sometimes, a noticeable lump or mass may form on the side or abdomen where the kidney is located. This lump is generally painless, but its presence may signal the growth of a tumour. The mass may be palpable or visible under the skin if it becomes large enough. This is more common in advanced stages of <\/span>kidney cancer when the tumour has grown large enough to be detected.<\/span>\u00a0<\/span><\/p>\n <\/p>\n Kidney cancer can sometimes lead to anaemia, which is a condition in which the body lacks sufficient red blood cells to transport oxygen. Anaemia can cause fatigue, pale skin, dizziness, and shortness of breath. This may result from the kidney’s reduced ability to produce erythropoietin. It is a hormone that helps stimulate red blood cell production. <\/span><\/p>\n \u00a0<\/span><\/p>\n In the later stages of <\/span>kidney cancer, when it has spread to other parts of the body, symptoms can become more pronounced and affect other organs. Metastasis can cause bone pain, difficulty breathing, or jaundice (yellowing of the skin and eyes) if the cancer spreads to the liver. Swollen lymph nodes can also indicate that the cancer has spread beyond the kidneys.<\/span>\u00a0<\/span><\/p>\n <\/p>\n Also know more about how to <\/span>Prevent Kidney Cancer<\/span><\/b><\/a>\u00a0<\/span><\/p>\n <\/p>\nWhat is Kidney Cancer<\/b><\/a>?\u00a0<\/b><\/span><\/h2>\n
