# Kidney cancer symptoms: blood in the urine

> Source: World Aid Network — https://worldaidnetwork.org/cancer/kidney-cancer/symptoms

## In short

Blood in your pee is the kidney cancer symptom you should never ignore, even if it happens once and does not hurt. A lump in the side, persistent back pain, or weight loss without trying also need a GP visit.

The kidneys sit under the ribcage at the back. Early kidney cancer often causes no pain. That is why visible or dipstick blood in urine is investigated.

## Which symptoms should you report?

You do not need every item on the list. Blood in the urine alone is enough.

- Blood in your pee — even once, even if there is no pain
- A lump or swelling in your side or lower back
- Persistent pain in your side or back
- Weight loss, fevers or night sweats without a clear cause

## Why is kidney cancer found by chance?

CT and ultrasound scans done for other reasons often pick up small kidney masses. Stage 1 survival is over 90%, which is why incidental findings are taken seriously rather than ignored.

## Does smoking raise kidney cancer risk?

Yes. Smoking is a major risk factor, along with obesity and high blood pressure. Stopping smoking still helps after a diagnosis.

## Key takeaways

- Blood in the urine should be checked even once.
- Early kidney cancer is often silent.
- Stage 1 survival is over 90%.

## Frequently asked questions

### Can a urine infection cause blood in pee?

Yes. Infections are common. GPs still investigate unexplained or repeating blood, especially in adults over 45.

### Is pink urine always cancer?

No. Beetroot, medicines and infection can colour urine. Cancer is why it is still checked.

### Do you fund kidney cancer surgery overseas?

When a partner urologist has recommended it for a patient who cannot pay.
