New research identifies link between drinking water disinfection byproducts and risk of colorectal cancer in men

Results from a large population-based cohort study including 60,000 men and women in central Sweden suggest that exposure to higher concentrations of disinfection byproducts in drinking water is associated with elevated risk of colorectal cancer in men.

Drinking water is a very important part of our diet that is consumed daily by essentially everyone in the population. Hence, assuring a that the public drinking water maintains a high standard is crucial. Chlorination of drinking water is a cheap and effective method widely used to control waterborne infectious disease. A drawback is, however, that reactive chemical byproducts can be formed in the drinking water, some of which have been proposed to cause cancer.

Trihalomethanes are the disinfection byproducts that are formed at the highest concentration in chlorinated drinking water. Several of these substances can damage DNA and cause tumors in the colon of rodents. Studies in humans are limited but some indications that trihalomethane exposure increases the risk of bladder and colorectal cancer exist.

In the study, 60,000 middle-age and elderly men and women with varying levels of disinfection byproducts in drinking water were followed for 22 years.

The results suggest that men with the highest exposure have a 20% increased risk of colorectal cancer overall and 60% increased risk of left sided colon cancer compared to unexposed men. In women no overall association was observed. Because many Swedish drinking water producers only use small amounts of chlorine in their production, these findings were observed at lower trihalomethane concentrations than in most previous research studies.

Together with the evidence from animal studies and previous epidemiological studies, the findings of this new study adds disinfection byproducts to the list of other possible environmental risk factors. Given that more efficient and chemical free disinfection methods exist today, exposure is preventable.

Drink urine. First it is filtered at the water plant. Then it is filtered in your fridge or filtering device. The it is filtered again by the kidneys. Least chance of causing cancer.

I filter our water with a zero water filter. I have no idea if it filters out chloramine.

> Drink urine.

I’ll leave that for the alphabet people.

> WC Fields had this figured out a long time ago.

As I recall, his reason for avoiding water was that "Fish f**k in it."

True enough then. But these days it's even worse. WC was referring to normal male/female fish relations. But today we have to worry about the byproducts of fish relations that include LGBTQF (you know what the F stands for).

Poor WC would have a coronary today faced with this mess.

From your earlier post:

I take it Chlorine and / or Chloramine kill gut bacteria and they need to be replenished.

I use a RainSoft Home RO filter. Checked with the company’s website and it said it does remove Chloramine in addition to other additives. Relieved to know.

We had a water filter system installed by Culligan, not sure if it filters out chloramine, I’ll check into it.

I ask the question of my daughter-in-law who has a PHd in water engineering. I also sent her the link to the main research article for her feedback.

She replied that her labmates at UNC Chapel Hill studied this exact topic and has forwared the article to them for feedback.

The reason gor my concern is that my municipal water has chloramines. I’ve known this for 12 years as chloramines do not leave by boiling water for brewing beer and spoil the beer. You cannot filter them out except with very expensive filters. I use a reverse osmosis filter and sometimes carbon filter it.

Tomorrow, I am headed to the oncologist and surgeon as I have colon cancer for the second time in 12 years. Just got the biopsy and pet scan results and its malignant.

First time was left side descending colon, same as the article. This time it’s colon cancer in my left lung, a two inch mass!

I’m going to take the article along to my oncologist appointment tomorrow at Duke University Cancer Center.

Thank you Conservative Mind for this, and all the articles you post.

🙏🙏🙏

I googled this topic again and found sevrral results. I don’t trust them all as thru are made by companies promoting products.”

1. “UV light is an extremely effective method of removing both chlorine and chloramine from water. It uses ultraviolet light to break down these chemicals, does not affect water taste, and performs the extermination in only a few minutes.”

2. “Chloramines are best removed from water by catalytic carbon filtration. Catalytic carbon, activated carbon with an enhanced capacity for contaminant removal, is one of the few filtration media that can successfully reduce chloramines from drinking water.”

3. “A carbon filter is the best way to remove chloramines from your tap water. If you want to go the extra mile, you can also use a reverse osmosis system.”

4. “Chloramine cannot be easily removed from water via evaporation and must be neutralized using dechlorinator. If you are sure your tap water contains chlorine and not chloramine, you can let the water sit for 1-5 days to allow all the chlorine to evaporate.”

5. “Chloramine requires a longer contact time with the filter media for it to be thoroughly removed, so don’t expect a Brita water filter to completely remove this impurity.”

6. “What neutralizes chloramine?
Ascorbic acid and sodium ascorbate

Ascorbic acid (vitamin C) and sodium ascorbate completely neutralize both chlorine and chloramine, but degrade in a day or two, which makes them usable only for short-term applications.”

7. “What breaks down chloramine?
The most common chemical to neutralize chlorine and chloramine is potassium metabisulfite, or Campden tablets (Campden tablets sometimes use sodium instead of potassium but the final result is the same). These tablets are often used in brewing operations to achieve the same disinfection results and remove chlorine.”

Another article:

“Standard activated carbon – either coconut shell or coal-based – does an excellent job at filtering free chlorine, but does very little to remove chloramine, “

“Chloramine, on the other hand, will still be present in water after two weeks despite being exposed to direct sunlight. You can see how the use of Chloramine would be much more cost effective in water treatment plants and water delivery systems.Oct 1, 2015

Sir, I hope you get the best therapy you can find.

If in doubt, MD Anderson in Houston and the Mayo Clinic, are top cancer choices.
