Can kidney cancer be detected by blood tests?

Honestly, routine blood tests don't directly show kidney cancer. They mostly just check how well your kidneys are working. My uncle went through this, and the doc had to do an ultrasound and CT scan to find the actual issue.

I got my CBC report today and some values are slightly up and down, and now I'm super stressed about serious things like cancer. Has anyone else panicked like this after seeing normal blood reports? Do I need to request an ultrasound just to be totally safe?

I was actually wondering about this too because my father has some back ache. Can routine blood tests show at least some warning signs, or do we have to ask for a specific kidney test? If anyone has gone through this, please let me know.

No, bro, blood tests won't catch it directly. You might see some abnormal creatinine levels if kidney function is dropping, but that's about it. If you're feeling off, don't just rely on your annual health checkup report; go get a proper scan done.

If blood tests could easily catch everything, doctors wouldn't make us lie down in those giant, noisy MRI machines! Seriously, blood work just gives a little hint. Don't stress yourself out reading random stuff online, just go get a proper checkup.

My brain is running on 3 hours of sleep and half a cup of chai, but even I know blood tests alone won't show the big C. They usually look at basic functions or anemia. You really need an ultrasound or a CT scan, so skip the Google rabbit hole and ask a doctor.
