Can chemotherapy cause cancer?
« on: 14/07/2017 11:37:23 »
For decades everyone has suspected that Chemotherapy causes more cancer and causes the cancer to spread but the mainstream medical establishment in cahoots with the money making Big Pharma always denied this even though all the "anti" cancer drugs actually come with these warnings.

For example tamoxifen causes cancer oncologic side effects including numerous endometrial abnormalities have been reported with tamoxifen use. These have included both endometrial adenocarcinoma.

Research by scientists last week have confirmed what smart and informed people knew all along that Chemotherapy causes cancer to spread.

A number of anti-cancer treatments (including chemotherapy and radiotherapy) try to kill fast-dividing cells by damaging DNA or by interfering with DNA copying.

This causes further mutations to the already-damaged cancer cells, killing many of them.
But a few cancer cells may survive the treatment, and some of these further mutations may be in areas of DNA that allow metastasis.

The pharmaceutical trials will indicate the extent of life extension as a result of the medication - and in some cases these are quite significant.
What they cannot predict for an individual is whether the period of disability due to the treatment is outweighed by the extension of healthy life.

Your post makes no sense.
You say "mainstream medical establishment in cahoots with the money making Big Pharma always denied this"
And then you say that they don't deny that the drugs can cause cancer- they even put a warning on them saying that they do.

That isn't denying the problem, is it?

Your question is a bit silly. Being alive causes cancer. Your cells are constantly dividing (replicating). Mutations happen all the time, and eventually, one of these mutations will cause cells to multiply uncontrollably.  The risk goes up as you age because the number of mutations accumulates. Everyone eventually dies of cancer if they do not die of something else before that. Things which damage the body increase the likelihood of mutations. Chemotherapy damages the body, but it is often necessary to treat the cancer to prevent the patient dying. Note that once a person develops cancer, they are at increased risk of developing another cancer even after the initial tumor is removed.
Also, please note there is no conspiracy between pharmaceutical companies and regulatory authorities. This is a conspiracy theory popular among those who know little about the medical regulatory process. Although some pharma companies occasionally do dodgy things like many businesses, the regulatory authorities are not engaged in any kind of "deal" with pharmaceutical companies to profit from the sale of inappropriate medications. When pharma companies do the wrong thing, they are soundly punished, and regulations are becoming stricter, more precise, and more effective each year.

I am afraid you are unaware of how the regulatory authorities have been infiltrated by big pharma staff in a revolving door scam

Also the staff have been offered inducements to get dummy 'consultant' jobs after they leave their posts.Most iof them conflicts of interest already.

I have done actual research on this while you just watch the 10.00 news which is highly edited to keep you asleep or distract you with terrorism related scare mongering to keep you in a constant state of fear and terror.

So do you actually work for big pharma?

Just google 'big pharma dirty laundry' for thousands of articles from many diverse sources on the massive amounts of bribery,fraud and corruption.

Chicken and egg problem.

By the time you have been diagnosed and prescribed chemotherapy, it's quite likely that secondaries have already been seeded.

If the chemo is successful in removing the primary and all the secondaries, you may live long enough to develop another cancer. Indeed as your cells have already shown a predisposition to mutate, it is the most likely cause of your next illness or death.

@profound So if you develop cancer you will be refusing all medical assistance. What else is there? Cross your fingers and make a wish perhaps? My mother died of cancer many years back. In those days they thought it best not to inform the patient of the terminal nature of their malady. They did tell my father. But my mother guessed anyway. No treatment just pain relief as and when. I wouldn't wish it on my worst enemy.

I personally would refuse chemotherapy if that would be the only choice being offered to me. The ignorance of people in modern biology is just silly. There's plenty of alternative medical options to chemotherapy being discarded by doctors. Research about the anti-cancer properties of curcumin and green tea for example.

Can chemotherapy cause cancer? I guess it can increase the cancer progression by weakening the immune system of the patient and cause permanent (cytotoxic) damage to cells.   

Just my 2 cents... ;)

Googling conspiracy theories is not what I would call "research". There are thousands of articles about all kinds of conspiracy theories on the web, none of which constitutes evidence of any kind. I would also like to call attention to a recent study of people who believe conspiracy theories, which found they perform significantly lower than average on analytical thinking tasks. https://www.ncbi.nlm.nih.gov/pubmed/25217762

The phrase "conspiracy theorist" is a derogatory smear phrase thrown at someone in an attempt to paint them as a lunatic. It's a tactic frequently used by modern-day thought police in a desperate attempt to demand "Don't go there!"

 a "conspiracy" is simply when two or more people plot to commit an act of deceit (or a crime).

Thus, when three hoodlums plan to rob the local Quickie Mart, they are engaged in a "conspiracy" and will likely be charged with a "conspiracy to commit armed robbery" in addition to the different crime of "armed robbery." The fact that they planned it with several friends makes it a "conspiracy" worthy of additional felony charges, you see. When these charges are brought up in court, the judge doesn't look at the prosecutor and say, "You are a conspiracy theorist!" That would be absurd.

I agree. Too often mainstream media (msm) will use deceitful tactics in labeling some entity doing independent research a "conspiracy theorist". I don't know why independent research is being systematically discarded on the internet by msm trolls.

In reality, the ignorance of people in science is the reason mainstream media is falsely accepted as the truth. @profound, please continue your investigations. I respect people asking insightful science questions independently of the msm trolls seeking to hijack your thread with spam.

Nice try
However the grown-ups will realise that
" conspiracy theory"- which is what you said
 is not the same as " conspiracy " which is something else.

Did you somehow think we wouldn't recognise that you moved the goalposts there?

you say "I don't know why independent research is being systematically discarded on the internet by msm trolls."
Do you have any evidence that this is happening?
And, for the record, pointing out that you are foolish to claim  that NASA went back in time to put contrails in a Constable painting from centuries ago is not "the mainstream media" discarding research.
It's common sense.

In any event, you still miss the point.
Many drugs used as treatments for cancer (especially some of the older ones) are likely to cause cancer.
Many of them are mutagens, some are known carcinogens.
That's perfectly well documented in all the literature.
The OP says " Big Pharma always denied this"
and that's simply not true.

You are confusing the results of in-vitro and/or animal research with human first-line treatment.

Here's what you'll end up with in terms of any peer-reviewed data suggesting that curcumin or green tea can be used as a first-line anti-oncogenic:

Well people like you always are always disparaging anything which is different or might change the status quo.

This is usually due to personal gain of some or inducement.I would not be surprised you were a 'consultant' to this or that as so many are nowadays.

The other reason would be impose your moribund viewpoints on others.

Not much different from religious zealots.

 People who are not skeptics of "official stories" tend to be dull-minded. To believe everything these institutions tell you is a sign of mental retardation. To ask questions, on the other hand, is a sign of higher intelligence and wisdom.

What is a "conspiracy theorist?

The pejorative "conspiracy theorist" is meant to demean and ridicule skeptics of official stories.

The idea, then, that there is no such thing as a conspiracy is flatly ludicrous. And people who condemn others as being "conspiracy theorists" only make themselves look mentally impaired.

Our modern world which is full of collusion and conspiracy -- and yet you somehow DENY the existence of any conspiracies at all -- is an admission of a damaged brain. Of course there are conspiracies, and when people analyze those conspiracies, they are "theorizing" about what happened. This is, in fact, precisely the job that police detectives and law enforcement agents carry out almost daily.

Most police detectives are, in reality, "conspiracy investigators" and analysts.
