Mother complain of back pain to her primary doctor for quite some time he gave her pain pills told her she needed to stop smoking an loose some weight

It is hard to tell you whether you have a case worth investigating on those facts. If renal carcinoma was causing the back pain, however, the big question in the case will be whether an earlier diagnosis would have made a difference. A three month delay is not a long time, especially if your mom had cancer that was symptomatic.  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.  Click here for an article that discusses the three main questions I ask when deciding whether to investigate a potential medical malpractice case.

Please note that by attempting to answer your question, I am not acting as your attorney. I will do nothing further to protect or preserve your interests in the absence of any additional discussion with you about this matter. John Ratkowitz, Esq.
