why do doctors  do ex rays or ct scan  for one thing and discover a dark spot on the kidney by accident and say dont worry its nothing and 2 years of bleeding pain pullups and other stuff then just to discover that when the patient questioned the doctor before was ignored and now diagnose with kidney cancer which could have been cured 2 years earlier tell me that answer  hey why doctors play god and think were all dumb and how dare we question you guys. you may of went to school for this but does not mean you know everything.For example fen fen was a diuretic  used for obese people but it took 50 years for doctors to fess up it destroyed hart vales  why is that hey why you may think this may not be for you to answer but this applies to all doctors for all  things also the cure for cancer if cancer is in all of us and some get it others dont its not an off switch its whats missing in the body it is like the game kerplunk   pull  too many sticks out it all falls apart leave them  all in nothing happens . Its an enzyme people loose  radiation and chemotherapy talk about  old school do a study on what each cancer patient is missing sometimes it does not have to do anything it just has to be their to keep the rest in place  . Yes call me crazy I do not care but long long time ago people believe a simple thing as  a doctors washing their hands before surgery  was a waste of time so I pose to you and your fellow doctors look for the block support of the body if we all carry cancer then our own bodies have the cure sometimes its so simple it is actually looking at you but every one cannot believe it because it goes against whats taught ---Good thing BEES do not believe in the Laws of physics  or they would not fly amazing a big body tinny wings yet it defies all the laws of gravity physics etc imagine if doctors would think in the same path way I wonder you should too all good hiding places are in front of you too see yet blinded by the simplicity of it

Hi, Thanks for writing in. At times, features of a disease on an X-ray and CT scan is not characteristic and obvious to the eyes years before it manifests in to a disease that could be hurting. I guess unfortunately such an incident has occurred with you. The dark spot which you questioned was probably looking more normal and acceptable on the X-ray and CT scan earlier. Many doctors choose to follow up such findings and this is subjective. Therefore, any such normal findings might be passed as harmless. The patient is usually cautioned to follow up with the doctor. Many medicines are initially discovered for treatment on one disease condition and are later found to help in other conditions. There are clinical trials at multiple levels before a medicine for cancer might be implemented for regular use in patients. The topic about scrubbing before surgery is a time tested practice and confirmed to reduce chances of infection. There are many arguments in medicine and most are sorted out with research and evidence based medicine followed in modern day. Please do not worry.
