Is there any way a doctor can check for cancer in general? in other words, i would like to check for any kind of cancer in my body?

Not really: There are numerous types of cancer screening tests depending on one’s age/sex/risk factors (family history, smoking, sexual activity, etc), but other than possibly a PET scan (which is expensive & not recommended for screening, rather for staging). The best thing is proactive health/prevention with good diet/regular exercise/adequate sleep/not smoking/healthy relationships/regular Dr checkups

Agree with Dr. B: There is no single or general test for cancer. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
