6 early warning signs of kidney cancer
Kidney cancer, also sometimes called renal cell carcinoma (RCC), originates in the kidneys, the vital organs that filter waste products and excess fluids from the bloodstream through urine. Kidney cancer typically begins as an uncontrolled growth of abnormal cells within the organ’s tissue. As the disease progresses, it can invade nearby structures and spread to other body parts. The following are a few common early warning signs of progressing kidney cancer.
Blood in the urine
One of the most common early signs of kidney cancer is blood in the urine (hematuria). Depending on the discharge quantity, it can make the urine appear pink, red, or brown. Blood in the urine can also occur due to other conditions, so it’s essential to consult a healthcare professional if one notices this symptom.
Pain or discomfort
Some people with early kidney cancer may experience pain or discomfort in the lower back or on the side where the affected kidney is located. This pain may be dull and persistent.
Lump or mass
In some cases, a palpable lump or mass may be felt in the abdomen or side of the body. However, not all kidney cancers produce a noticeable lump. A swelling of the organ can be confirmed with a physical exam.
Unexpected fatigue
Unexplained fatigue or general weakness can sometimes be associated with kidney cancer, especially as the disease progresses.
Loss of appetite
Kidney cancer can trigger metabolic changes, leading to a decreased appetite or a feeling of fullness. A loss of appetite can worsen existing fatigue.
Swelling in the legs and ankles
Rarely, kidney cancer may cause swelling in the legs and ankles. The swelling is due to the pressure on blood vessels and fluid balance.
Early detection and treatment can improve the prognosis for kidney cancer. Remember that one may not have noticeable symptoms until the disease has advanced to severe stages. Regular check-ups and screenings are crucial for individuals at higher risk, such as those with a family history of kidney cancer or certain genetic conditions.
