    Qui a eu carcinome in situ (cis et comment il l’on détecter?




    Who has had carcinoma in situ (cis and how is it detected?




    Hi Coeur51:

    I have had bladder cancer 3 times.  I was first diagnosed in 2008 and then again in 2010.  Both of those times were papilliary tumours.  In September 2022 I discovered that I had carcinoma in situ.  All three times my bladder cancer was confirmed visually with the cystoscopy exam which is a camera that is inserted up the urethra to see the inside of the bladder.  This is the most common way to confirm the presence of bladder cancer.  Doctors can also have you do x-rays, ultrasounds, MRIs etc. depending on the situation.

    After surgery to remove the tumours the samples were sent to pathology to be confirmed as to type, stage and grade of cancer.  As mentioned, this time it was carcinoma in situ.  CIS is usually a flat reddish coloured tumour.  Mine was very early and a yellow tan colour.  Unfortunately it can be more aggressive than the papilliary tumours so it is important that you follow your doctor’s advice for any recommended follow up treatments and checkups.

    After my September surgery my doctor instilled a chemo drug called Epirubicin in my bladder.  He recommended it because he felt it was necessary to eliminate the possibility of the tumour reseeding itself.  I am now in the middle of BCG immunotherapy treatments as a followup to help stimulate my immune system to hopefully prevent the cancer from coming back.

    I hope that my information helps.  Please let us know if you have any other questions.  ((((HUGS))))


    @mary sue merci beaucoup de votre réponse//




    Hi Coeur51,

    In my case, I first became aware of the possibility of Bladder Cancer when I discovered small blood clots in my urine.  I was in Florida in the summer and had just completed a 5 k run.  I went to the toilet and noticed these small dark specs – the blood clots.  When I returned home, I happened to take part in a 5 k race on a very warm humid day and after the run, I had to pee really bad.  When I went to the toilet, all I saw was blood, there was no clear urine.  From there I made an appointment to see my family doctor who immediately got me into see a Urologist and it was confirmed I had low grade non-muscle invasive bladder cancer.

    I am a 13 year survivor.

    My best,
