My doctor found a polyp and prostate exam three and half years ago told me not to worry about it now I have colorectal cancer

You certainly have good reason to investigate a case.  The big question in most failure to diagnose cancer cases is whether the patient can prove that the doctor’s negligent care caused the damages suffered by the plaintiff. In essence, the plaintiff must be able  to show that earlier intervention would have changed the outcome. This is  a fact sensitive inquiry. An attorney will have to review the medical records and often get experts to review the pertinent radiography films to determine when accepted standards of care should have compelled a doctor to investigate the possible diagnosis. Then, if it is determined that the cancer was present and detectible, the next question becomes what was the likely stage/prognosis when the cancer should have been discovered. If the cancer was at an early stage when it should have been discovered, the case is more likely to be viable. If you want to investigate your case further, you should contact a local medical malpractice attorney (one in your state).  They take these cases on a contingency basis which means you only have to pay if you succeed.  Additionally, initial consultations are usually free. You can use the "Find a Lawyer" service through this website to research medical malpractice attorneys.  Then, visit each attorney's website and look for a firm that has a record of successful verdicts. If you are unable to find a lawyer who meets these qualifications within your state, sometimes you may contact an out of state lawyer who can refer you to a qualified attorney in your state while providing support related to the issues of medicine.
