Questioning Chemotherapy:
Is it safe? Is it effective? Is it necessary?
by Ralph W. Moss, Ph.D.
reviewed by Ed Hill
It is reported that cancer is now the leading cause of death for people
under the age 85. Every year, more and more people with cancer are being
given chemotherapy. Is chemotherapy safe? Is it effective? Is it necessary?
In Questioning Chemotherapy, author and researcher Ralph Moss offers
information and advice to help the reader make wise decisions for themselves
and those they love.
Moss says that people who agree to receive chemotherapy have accepted the
idea that even if a notoriously toxic and expensive treatment cannot cure,
it must at least have some beneficially effect on the patient. The reason
this idea is accepted is that the public has been subjected to a media
barrage reporting the supposed success of new treatments. According to Moss,
there are several ways people are led to believe they will be helped, even
when there is not trust-worthy evidence.
One of the most misleading assumptions people make when they read reports
about idea that shrinkages or "response rates" have anything to do with
increased survival time or improved quality of life. For example, when a
patient asks, "What are my chances?", the doctor may give an
impressive-sounding "response rate" like 60%. No explanation is given of
exactly what "success" or a "response" is or whether it actually correlates
with increased survival. In fact, says Moss, such a correlation has not been
proven for most kinds of cancer and cancer treatments. The doctor talks
"response rate" but the patient hears "cure"! These patients and their
family members may be disappointed, or even furious, when they later realize
that increased "response rates" often do not mean increased survival or
improved quality of life. Application of chemotherapy drugs may indeed
result in a temporary shrinkage of measurable tumors for some patients. But
what are the long term results of some shrinkages? Does the patient survive
any longer?

This most basic question is almost never asked, let alone answered.
Deceptive Reporting
Moss describes 4 major problems with reporting of cancer research that can
deceive patients, and even doctors, into believing that a treatment offers
more promise than it actually does.
Lead-time bias: Lead time bias accounts for much of the illusory
"improvement" seen in the last few decades in treating many kinds of cancer.
We are told, "The earlier the cancer is found, the longer the patient
survives."
Because we are getting better at detecting cancer, we can detect it sooner.
Even if the patient dies at the same time as if the cancer had not been
detected or treated, if the cancer is detected earlier, he will live longer
after detection. Actually no time has been added to the patient's survival,
but the statistics look much better.
Stage migration: With better diagnostic equipment, patients' metastases are
being found in an earlier "silent" condition. Thus, they are being staged
differently, and placed into more advanced categories. The net result is
that patients appear to have considerably improved survival rates for their
stage. But this is merely another statistical artifact.
Publication Bias: Positive results of drugs are more quickly and frequently
published than negative ones.
Selection bias: This bias arises if responders to therapy happen to be those
patients who would have lived longer anyway, whether or not they had
received the treatment. When they live longer, the credit is given to
therapy.
Chemotherapy's "Rubber ruler"
Another way patients can be misled is by the use of the term "cure".
According to Webster's Dictionary, a cure is "something that corrects,
heals, or permanently alleviates a harmful or troublesome situation". To the
cancer establishment, the word "cure" has a different meaning. For them a
cure can be a 5-year, a 3-year, or even a 1-year interval of survival, free
from cancer. The definition of "cure" varies depending on the type of cancer
and on the individual patient. Moss calls this using a "rubber ruler" to
construct definitions of "cure" to fit the chemotherapy establishment's
purposes.
Suppose a patient has cancer that goes into remission after treatment.
Several months or years later there is a recurrence, and the cancer returns,
more aggressive than it was before. Moss asks, "Is that a cure? Not by any
common meaning of the word, yet that very thing can happen with a cancer
"cure"."
Hypocrisy
According to studies cited in the book, the vast majority of oncologists
refuse to participate in clinical drug trials. Many or most reject
chemotherapy for themselves or their own families. Yet the same doctors
continue to prescribe it for their patients. Moss asks, "What should we call
this?"
Not an effective weapon
The author notes that chemotherapy is very good-for the balance sheets of
drug companies. It builds careers. It may even offer patients and their
families a sense of hope (albeit false) in hopeless times. But he argues
that chemotherapy is not an effective weapon against the vast majority of
cancers in adults.
It rarely extends overall survival, and the little advantage that may be
gained is generally offset by the damage that is done. Chemotherapy should
not be regarded as a "proven" or conventional treatment for most cancers.
Less toxic alternative treatments are still desperately needed.
What should you do?
Moss emphasizes that patients and their families need to question their
doctors before consenting to any treatment (a good practice with any medical
diagnosis or treatment). The key question to ask is, "What proof is there
that the treatment being offered will cure, extend actual survival, or
increase the quality of life?" Ask to see scientific papers and reports on
the treatment. If necessary, seek professional help in interpreting this
information.
You have a moral and legal right to ask for, and be given, that information.
Be on your guard against evasive maneuver of all kinds. Be especially wary
of doctors who say, "Our treatment is so new that we haven't had a chance to
evaluate it yet."
Moss passes on hard won advice from a cancer patient's widow who wrote,
"Question your doctor. Question him every step of the way. The more serious
the condition, and the more drastic the treatment, the more stringent the
questioning must be. If you don't have the energy, enlist the help of
someone who does… Don't be afraid to fight. Question your doctor the same
way you would a politician, for the 2 are not dissimilar. If your doctor
won't answer the questions, find one who will… There is a party line within
the medical system. Question your doctor, always."
If a drug or regimen has not been proven to cure, significantly prolong
actual survival, or improve the quality of life-if it only temporarily
shrinks tumors, with a probable loss in well being-then it is, at best,
experimental and unproven, and should not be represented as anything else.
At worst, it could be not only ineffective, but painful, destructive, or
even fatal.
It may be time to look into other alternative, nutritional, or nontoxic
treatments. It is Moss' personal opinion that the best of these treatments
are based on more plausible theories and offer more compelling evidence than
most chemotherapy. They certainly do far less harm.
Patients and their loved ones are often understandably devastated when they
learn that they have cancer. It is an additional blow to learn that
chemotherapy is not likely to help, much less cure. But cancer is not a
death sentence. It can be a turning point. The end of illusions can be the
beginning of wisdom.
