Researchers have investigated what influence coffee has on a type of cancer.
The effect observed was dose-dependent.
Scientists have published a new
study
.
Coffee
is said to reduce the risk of death in cancer patients.
The beneficial effect on
health
was dose-dependent.
Phoenix / Arizona - Is
Coffee
Healthy Or Not?
Scientists have been arguing about this question for decades.
Studies
confirm that the popular hot drink has some positive effects on
health
.
Coffee is said to reduce the risk of diabetes and make the blood vessels elastic.
In addition,
coffee
is said to have
an influence on cancer.
For example, studies have repeatedly shown that coffee consumption is associated with a lower risk of disease and death from uterine and liver cancer.
The influence on
colon cancer
has also already been investigated.
Two previous studies had
scientists
found that coffee drinkers a
cancer
disease infection
Survive up to stage III more often if they also take medical therapy.
Does coffee help against cancer?
New study published
Christopher Mackintosh of the Alix School of Medicine at the Mayo Clinic in Phoenix, Arizona has now investigated the effects of coffee on patients with stage IV disease.
In this advanced
stage of cancer
, a cure is no longer possible because of the metastases that have formed.
The result:
coffee drinkers
suffered a relapse later and their survival time was longer than that of non-coffee drinkers.
Every single cup a day was associated with a five percent lower risk of tumor progression.
The
risk of death
fell by seven percent with each coffee mug.
Cancer: The positive effect of coffee was dose-dependent
The positive effect was dose-dependent: patients who
drank
at least four cups of
coffee
a day had a 22 percent reduced
risk of
disease progression and a 36 percent reduced
risk of death
.
More coffee consumption improves survival time with colon cancer.
This Harvard study reinforces the results of other studies that previously even showed protection against some cancers from coffee.
Applies to decaf too.

The result does not mean, however, that
coffee drinkers had
a chance of
surviving
cancer,
which was
fatal at this advanced stage
.
However, the median survival time of 39 months was significantly longer than that of the non-coffee drinkers.
They died on average after 31 months.
Extending the overall survival of
cancer patients
by eight months would be a great success in a therapeutic study.
According to experts, the
corresponding
drug
would have a good chance of receiving approval from the drug authorities.
That won't be the case with coffee.
The reason: The
extension of life
is not a sure proven effect.
As cancer progresses, it may have ruined your appetite for that daily cup of coffee
No causality can be established in an observational study.
It could even be that faster
cancer
progression
has spoiled
the patient's appetite for that daily cup of
coffee
.
The study authors try to rule this out.
To do this, they only want to consider tumor progressions that occurred 180 days or later after the start of therapy.
In order to
clinically prove
the effect of
coffee
in cancer diseases, patients in a study would have to be
randomized
to the consumption of
coffee
or a placebo drink
before starting treatment
.
Although this is theoretically possible, it is difficult to implement in practice.
Because: Consumption is difficult to control.
The positive effect can only be proven if
researchers
isolate the substance responsible for the suspected cancer preventive effect and use it to produce a drug.
