Causes and risk factors
Kidney cancer occurs only in people who smoke?
పొగ తాగేవాళ్లకు మాత్రమే మూత్రపిండ క్యాన్సర్ వస్తుందా?Smoking raises the risk, but kidney cancer also occurs in people who have never smoked. Excess weight, high blood pressure and some inherited conditions are other risk factors.
Read the factsMyth #02 · Causes & riskKidney stones eventually turn into kidney cancer?
మూత్రపిండాల్లో రాళ్లు చివరకు మూత్రపిండ క్యాన్సర్‌గా మారుతాయా?Ordinary kidney stones do not turn into cancer. Long-standing stones and inflammation are linked to some rare urinary tract cancers, but this is different from the common type of kidney cancer.
Read the factsMyth #03 · Causes & riskKidney cancer is always hereditary?
మూత్రపిండ క్యాన్సర్ ఎప్పుడూ వంశపారంపర్యమేనా?Most kidney cancers are not inherited. A minority are linked to inherited conditions such as von Hippel–Lindau syndrome, Birt–Hogg–Dubé syndrome and hereditary leiomyomatosis and renal cell cancer.
Read the factsMyth #04 · Causes & riskKidney cancer affects only elderly men?
మూత్రపిండ క్యాన్సర్ వయసు మళ్లిన మగవారికి మాత్రమే వస్తుందా?The risk rises with age and is higher in men, but women and younger adults can also develop kidney cancer.
Read the factsMyth #05 · Causes & riskDrinking more water can prevent or cure kidney cancer?
ఎక్కువ నీళ్లు తాగితే మూత్రపిండ క్యాన్సర్ నివారణ లేదా నయం అవుతుందా?Drinking enough water supports general kidney health, but extra water has not been shown to prevent or treat kidney cancer.
Read the factsSymptoms and diagnosis
Kidney cancer always causes blood in the urine?
మూత్రపిండ క్యాన్సర్ ఎప్పుడూ మూత్రంలో రక్తం తెస్తుందా?Many early kidney cancers cause no symptoms and are found by chance on a scan done for another reason. Blood in the urine can occur, but not always.
Read the factsMyth #07 · Symptoms & diagnosisIf there is no back pain, kidney cancer is impossible?
నడుము నొప్పి లేకపోతే మూత్రపిండ క్యాన్సర్ అసాధ్యమా?Small kidney tumours are usually painless. Pain in the side is more likely with larger tumours, and is not needed for a diagnosis.
Read the factsMyth #08 · Symptoms & diagnosisEvery mass found in the kidney is cancer?
మూత్రపిండంలో కనిపించే ప్రతి గడ్డా క్యాన్సరేనా?Some kidney masses are harmless, including simple cysts, oncocytomas and certain angiomyolipomas. The way a mass looks on scans helps decide whether further tests are needed.
Read the factsMyth #09 · Symptoms & diagnosisA normal urine test or kidney-function test rules out kidney cancer?
మూత్ర పరీక్ష లేదా మూత్రపిండ పనితీరు పరీక్ష నార్మల్ వస్తే మూత్రపిండ క్యాన్సర్ లేనట్లేనా?Urine tests and creatinine can be completely normal even when a kidney tumour is present. Scans are central to checking a suspicious kidney mass.
Read the factsMyth #10 · Symptoms & diagnosisEvery kidney tumour must have a biopsy before treatment?
ప్రతి మూత్రపిండ గడ్డకూ చికిత్సకు ముందు బయాప్సీ తప్పనిసరా?A biopsy is useful when its result could change the treatment plan, but it isn't needed for every suspicious kidney mass. Some go straight to surgery based on scans and assessment.

Every kidney cancer needs removal of the entire kidney?
ప్రతి మూత్రపిండ క్యాన్సర్‌కూ మూత్రపిండం మొత్తం తీసేయాలా?Partial removal of the kidney can preserve healthy kidney tissue in many cancers that haven't spread, particularly small tumours. Removing the whole kidney is still right for some larger or complex tumours.
Read the factsMyth #12 · Surgery & local treatmentRemoving one kidney always causes kidney failure or dialysis?
ఒక మూత్రపిండం తీసేస్తే ఎప్పుడూ మూత్రపిండ వైఫల్యం లేదా డయాలసిస్ వస్తుందా?Many people live well with one working kidney. The risk of long-term kidney disease depends on how well the kidneys worked before, other health conditions, and the health of the remaining kidney.
Read the factsMyth #13 · Surgery & local treatmentRobotic surgery always gives better cancer control than conventional surgery?
రోబోటిక్ ఆపరేషన్ ఎప్పుడూ మామూలు ఆపరేషన్ కంటే మెరుగైన క్యాన్సర్ అదుపు ఇస్తుందా?Robotic surgery can offer technical advantages in some cases, but cancer outcomes depend on the tumour, the quality of the surgery and choosing the right patients.
Read the factsMyth #14 · Surgery & local treatmentAll small kidney cancers must be operated on immediately?
చిన్న మూత్రపిండ క్యాన్సర్లన్నింటికీ వెంటనే ఆపరేషన్ చేయాలా?Monitoring with regular scans (active surveillance) may suit some small kidney tumours, especially in older or frail people. Some patients may be suitable for ablation instead of surgery.
Read the factsMyth #15 · Surgery & local treatmentRadiotherapy has no role in kidney cancer because it is radioresistant?
మూత్రపిండ క్యాన్సర్ రేడియేషన్‌కు లొంగదు కాబట్టి రేడియోథెరపీకి పాత్ర లేదా?Conventional radiotherapy has had limited effect on kidney cancer. But modern stereotactic radiotherapy (SBRT) can control selected kidney tumours and areas of spread very well.

ముదిరిన ప్రతి మూత్రపిండ క్యాన్సర్‌కూ కీమోథెరపీయే ప్రామాణిక చికిత్సా?Standard chemotherapy works poorly against most kidney cancers. Immunotherapy and targeted medicines are the main treatments for many people with advanced kidney cancer.
Read the factsMyth #17 · Advanced disease & survivorshipImmunotherapy cures every patient with metastatic kidney cancer?
వ్యాపించిన మూత్రపిండ క్యాన్సర్ ఉన్న ప్రతి రోగినీ ఇమ్యునోథెరపీ నయం చేస్తుందా?Immunotherapy combinations have improved outcomes substantially, and some patients have long-lasting responses. But not everyone responds, and cure remains uncommon when the cancer is widespread.
Read the factsMyth #18 · Advanced disease & survivorshipOnce kidney cancer spreads, surgery or radiotherapy can never help?
మూత్రపిండ క్యాన్సర్ వ్యాపించాక ఆపరేషన్ లేదా రేడియోథెరపీ ఎప్పుడూ సహాయపడలేవా?Some patients with a limited number of areas of spread benefit from surgery or stereotactic radiotherapy to those areas. Decisions depend on the extent of the cancer, medicine options and fitness.

మూత్రపిండ క్యాన్సర్, రీనల్ పెల్విస్ క్యాన్సర్ రెండూ ఒకే జబ్బా?Renal cell carcinoma starts in the kidney tissue itself, while renal pelvis cancer usually starts in the lining of the kidney's drainage system. They differ in biology, surgery and medicine treatment.
