ParticipantAs several BC patients who appear in this forum do not fit in the risk category such as smoking for working in dye and chemical industry. I am also the one, except my age, 71 years old which fits in the age risk category. So, I have been curious about what has triggered my BC besides older age.
I have found a published paper, which links bladder cancer to the consumption of coffee, especially for non smokers. The paper was published in 2008. The research was conducted by prevention research group of Japan national cancer research center. The research was conducted on over 100,000 men and women between 40 – 69 years old over 15 years span.
The finding says coffee drinker at least one cup a day with no smoking has 2.2 times higher of becoming bladder cancer than non coffee drinkers. I did drink coffee. It is noted that the author stated that he could not conclude if the consumption of coffee would risk the bladder cancer because only about 25% of people consumed more than one cup of coffee per day.
Below is the link to the paper. To see the whole paper, clink where it says “Free Full Text”.

ParticipantHi Joey:
I don’t put too much into these studies because as a researcher I know how these things can get skewed. As you probably know there has been a lot of debate about coffee consumption – how much, what type etc. and it difficult to come to any sort of conclusion.
I personally don’t drink coffee, not because of any studies – it just doesn’t agree with me. I love the smell and taste of coffee but my stomach says no go so unless I want heartburn everyday I avoid it. Yet I can drink tea of any sort with no ill effects. So go figure.
As for figuring out how I got bladder cancer, I nearly went stirry with that one. After learning about potential causes I came to the conclusion that with me it was simply exposure to years of second hand cigarette smoke – I’ve never smoked personally, combined with exposure to pesticides and consuming fish and swimming in polluted lakes and rivers. I also dyed my hair for many years. There has been some studies suggesting that dark brown and black hair dye can increase your risk of getting bladder cancer if used frequently. So while I have no definite proof if any of this actually caused me to get bladder cancer, I suspect that the possibility exists and let it go at that. As a kid, I had no control over what I was exposed to and have to let that go. It is what it is.
It is too late to change the past, but I can improve the future which is why I do things like trying to eat a better diet and exercise plus take vitamins etc. I do this in the hopes that it will make my body better and stronger and that in itself will lessen the risk of recurrence. I’ve also learned to like my grey hair.
My only frustration now is when things happen in my day that cut down the time for looking after myself. Our current cold spell coupled with a lot of snow make it difficult to get out for a walk so I need to get motivated and get on my stationary bike. Again it is what it is – I just do the best I can each day.
I hope and pray for a favourable diagnosis for you. (((((HUGS)))))

ParticipantHi Joey,
Praying your January 3 Pathology report will set you at ease.
Like Marysue, I am not a coffee drinker. As she said, it just does not agree with me – unless I want an upset stomach.
I can understand the frustration and desire to understand why we get BC. It led me to a search in order to find the cause(s) and to see whether there was merit in placing some adjustments to my lifestyle.
I also do not put a lot of credence in these coffee studies. Most things with moderation should be OK. Some coffee/caffeine studies show positive results. Other studies show negative results.
I am a Professional person, who spent his working career mostly behind a desk, No coffee, Never smoked, No constant second hand smoke exposure, No Dyes, No Diesel fumes, etc. etc. etc. Equally, a clean home. I got BC.
Recall that cancer occurrence is at the cellular level (Bad DNA resequencing during cell mitosis). Visible Cancer is a cancerous cell mass that has grown as a result of cloning off a “bad cell”.
Half of all occurrences of BC are gene related. The other Half, environmentally related (Environment may induce defective cell division). It may take 20 to 25 years following some environmental exposure before a cancer mass develops. So, the “bad exposure” may have happened years ago … only to have been forgotten.
I think I fell into the gene related camp – or either forgot or was not aware of a bad environmental exposure.
I am where I am. I have BC that is “in remission”. I can only continue to do the things my Doctor recommends in order to keep in the best of health.
God Bless

ParticipantHi Marysue and DDep
Thank you for giving me your feed back and concerns for my pathology result.
First of all, the result of Jan 3 meeting with my uro. I and my wife met him in his office and I received the copy of pathology after the meeting from the receptionist.
I think they used pre 2004 WHO grading system.
Diagnoses
A. Intermediate grade (2 out of 3) papillary transitional cell carcinoma, non-invasive.
B. No muscularis propia present for histologic evaluation.Gross description
a 1 cm aggregate of papillary mucosal tissues fragments in formalin. single container.I am scheduled to have a biopsy in April. I am assuming the biopsy in April will get sample also from muscle to determine the stage, but I am not sure. If the result is good, then I will move on to scheduled cysto examinations.
My uro said the majority of the patients are in grade 2 and a small percentage is in grade 1 and grade 3. I have read an article on the relationship of pre 2004 and after 2004 WHO grading system. So, I think I know what grade 2 means. I am also aware that without testing muscle layer, it is not sure if it has penetrated to the muscle layer or not.
My uro said it was a very good day for us and we should have a wine. I have known my uro for less than 2 months but I know his manner with his patients. He is a straight shooter. It is not certain he has talked to the pathologist or himself has seen the images of the pathology. At any rate, I would like think his comment came as the result of his overall review based upon his clinical result, the result of CT scan with IV and the pathology report and his experience.
I have noticed I have less anxiety but not exactly the same as before. Anyway, I will try to enjoy this three months. I am so glad that in spring, by the way the spring starts in March in Vancouver, I can start biking with my a year old puppy on the trailer attached.
Incidentally, I agree the statistical data can be skewed. It can be diet not coffee as I can think that people who drink coffee tend to have more western style diet where people who drink green tea may have traditional Japanese diet. What has interested me is that BC is #5,6 in NA where it is #14 in Japan or similar in Korea.
It could be gene, diet and environment. As I have a background in Asia and there are many Asia ethnic population in Vancouver I would like to focus on raising awareness of BC among Asia ethnic population as a volunteer for BCC.Wish everyone that the very best new year.
Joey
