Contaminants collect in the fatty tissues of the human body, the
filter units ( liver and kidneys ) and can become cancerous.

Fecal matter that was the main contaminant mentioned up to now sure
doesn't!

Contaminants tax the immune system, until one day the immune system
can't keep up with the chemical/organic insult anymore and disease
takes over.

Take solice in the fact that if all the fat-soluble toxins that are
currently stored in YOUR fat reserves were released into your
bloodstream all at once, you would be dead in short order.

Although there are fat-soluble toxic materials that get into people and
mostly from pollution,
the problem happens to mostly be small enough for overweight/obese
overeaters managing to later get down to normal weight to have health
benefits from losing fat rather than ill effects of reduced ability to
store toxic chemicals in dwindling fatty areas.

Cattle aren't expected to live long enough ( 4 to 6 years ) to show
signs of a deteriorating immune system, except in the cases of Anthrax
and BSE.

What about dairy cows?

Humans otoh, who want to see 80 years of age, better walk
the thin line and keep as many carcinogens out of their body as
possible, as many ACCUMULATE IN CONCENTRATION AND QUANTITY as the
years go by.

Some things to keep in mind:

1. Cancer is not the No. 1 cause of death in the USA. Heart disease is.

2. Most cancer is preventable by avoiding known causes and contributing
factors other than eating/drinking chemicals:

a) Lung cancer - by a large margin the biggest cancer problem, with a
very large majority having smoking as either sole cause or main essential
contributing factor. A distant second is known - radon, from buildings
being more sealed than they were before the 1970's energy "crisis".

b) Colon/rectum cancer - known to be much more common in people who are
overweight/obese. To a lesser extent, some evidence exists that a diet
lower in fat and higher in fiber helps.
That big study with results released recently and supposedly indicating
lack of benefits of such a diet only lasted 8 years and *did* show a
significant reduction of colon polyps (a precursor of colon cancer) and a
deemed-insignificant-by-the-studiers 9% reduction in breast cancer.
Oh, and the study was a fat-vs.-carbs one. The "experimental group"
reducing fat intake maintained calorie intake through carbs - although
"recommended"-healthy forms, fruits and whole grains. I expect that much
more significant cancer avoidance would have occurred if the dieters
actually consumed fewer calories and lost weight.
BTW, the lower-fat higher-carb group with same calories did not gain
weight. Actually they lost 5 pounds and gained back about half of that
for a very slight net loss. A major purpose of that study was to
determine if fat calories and carb calories were more fattening and the
results indicated close enough to a draw - with higher-carb lower-fat
being less fattening to an extent small enough to consider insignificant
and likely not always repeatable.

c) Breast cancer - known to be somewhat and significantly more common
among overweight people. By at least one account, breast cancer is twice
as common among obese women as among women who are not overweight at all.
Keep in mind that about .7% of breast cancers are in men!

d) Skin cancer - that took a big uptick in the 1980's and 1990's with an
uptick in popularity of suntanning, as well as population shift within the
USA to sunnier areas. There are many varieties of skin cancer:

Basal Cell Carcinoma - a more common less deadly one
Squamous Cell Carcinoma - another more-common less-deadly one

(Both of these require treatment but a week or month or 2-month delay is
unlikely to kill you)

Malignant Melanoma - I have heard of 7 varieties, with the 5 most common
of those 7 starting at visible primary sites on skin, the 4 most common of
all starting at dark-pigmented primary sites in skin, and the most common
3 of these being caused by sun exposure and especially severe sunburn.
One form ("acryl lentiginous"), I believe 4th-place of incidence of
malignant melanoma, is largely not caused by sunburn and occurs close to
equally among people of all races. 5 of the other 6 that I have heard of
occurs more among lighter-skin people.

But bottom line, I would not blame environment for most or even much of
cancers. Lifestyle choices and "go-along-to-get-along" could account for
a good 2/3 of cancers. Also, part of the reason that the USA has more
cancer is that nowadays Americans are getting more and better heart
and kidney disease and stroke treatment, better treatment of infectious
diseases, vaccinations against some bad infectious diseases, and after
that fewer war deaths and cars now being more crashworthy than they were
decades ago so Americans live longer to have a better chance at getting
cancer.
