The Other Face of Cancer by Dr Manu Kothari and Dr Lopa Mehta
Cancer As A Human Problem
Cancer, Timothy Foote34 writes,
is a mysterious plague that cries out not for philosophy,
but for a palliative. The cataloguing of the biological
features of cancer in the earlier chapter cannot
ameliorate the hurt feelings and the dis-eased body of a
cancer patient. Cancer is a human problem, as are other
diseases, and death. Haldane,35 the noted
geneticist, who died of a rectal cancer conceded that
cancer often kills, only to add with a
chuckle, that so do cars and sleeping pills.
What biological understanding can do for a cancer
patient, his near ones and even his doctors, is to help
them to see and tackle the issue without fear,
incrimination, rushing for needless therapies, or the
typical jaccuse from the doctor
to the patient because he came too late.
Cancer, so often, does not mean a death- sentence,
and is compatible with a long life. Freud, the father of
modern psychiatry, developed cancer of the mouth at the
age of 67, and died of something different altogether, at
the age of 83.36 It is not for us too choose
the whether, what and when of cancer. Rather when
cancer does occur, we must make the best of it.
As paradigms of human cancer, let us construct a model of
the disease, interspersed with pertinent biologic data,
in (a) any one of the three cancer surgeons, Mayo, Wilkie
and Borges (Chapter One), who died of cancer of the
stomach; (b) Aldous Huxley, who fell victim to a cancer
of the tongue, 37 (c) Lenore Schwartz, a young
Chicago scholar, artist and teacher who died of leukemia
at the age of 23, and in whose name the Lenore Schwartz
Leukemia Research Foundation at Florida was established,38
and (d) John Gunther, Jr., who died of a brain cancer
while still in his teens.39
The inception of the cancer, in each person listed
above, was as a very small, silent event that
predeterminedly affected, at one or more places, a small
number of cells - cells that were originally normal. The
newly formed cancerous cells started multiplying, but no
faster than normal cells as was hitherto thought. This
slowness of cancer cells proliferation, in
comparison with the rate of proliferation of normal
cells, confirmed over a wide range of cancers, 6,40,98,258,315
has led to the suggestion40 that cancer be
better regarded as a disease of cell-accumulation rather
than of rapid proliferation.
A cancer cell measures no larger than a normal cell -
one- hundredth of a millimeter across. This sheer
micro-size of a cancer cell accounts for the fact that,
following the inception of cancer, it must have
ordinarily taken several years before the cancer both-
ered these individuals, or came to the attention of their
doctors. On the basis of the modern cytokinetic studies,
it has been computed that any cancer, before causing
symptoms or striking the eyes of the clinician, takes
anything from two to seventeen years - two and a half
years for a rapidly fatal cancer as of the lung to
seventeen years for breast cancer. And during this
interval, there is no instrumental, immunological, or
biochemical method that could detect this microscopic
focus of growing cancer, be it the amazingly
sophisticated tomography,308 or the
quantitative imaging 311 designed to
synchronously scan up to 250 parallel transverse cross-
sections of the human body. A cancer just one cubic mm in
size is worth at least 1,000,000 cells.41 Any
diagnosable cancer is thus, at least
a-million-cell-worth, and many years old, with
twenty-four hours of each day of each year at its
disposal to leave the starting point and go and lodge
elsewhere in the blissfully unaware individual.42
Let us be happy that the six luminaries of our
story were not deprived of the much-sought-and-advertised
early-diagnosis for want of the latest
computer off the IBM assembly line. As far back as in
1927, Cheatle, 43 writing in the British
Medical Journal declared that when a lump
appears in the carcinoma, the disease is well advanced,
and is already threatening the patients life,
possibly beyond all hopes of cure. What Cheatle
said of breast cancer in 1927, Logan12
repeated in 1975, with the question - is there anything
like an early cancer?
In Mayo, Wilkie and Huxley, the discovery of the tumour
was sudden, and until that time they neither had the
knowledge of it, nor any problems. They were operated,
unrewardingly. Borges, a humanitarian as we knew him, was
feeling uneasy for some time, but he took it as gastric
upset and continued to work; then, one day, he was
investigated and operated upon. Borges lived and worked
for many months after that until the spread caused
obstructive jaundice to which he succumbed, with dignity.
A few months before his death, he delivered an oration
Pune ( Maharashtra State), India, and a part of the
oration is reproduced here, courtesy of Lr. Dr. Bhagwat,
lately of the Armed Forces Medical College, Pune: I
have treated thousands of cases surgically,
radiologically and by cytotoxic drugs. A number of times
people met me later and said, "Doctor, if I knew I
was going to live like this, I would not have come to
you." I have rarely failed to diagnose a case when
the disease was not quite controllable! I have left the
disease and removed the patient in many cases. I have
succeeded in leaving behind a trail of
family-malnutrition and many of their children without
education. I have now come to the conclusion that, let us
in every case ask whether it is not wiser to leave the
patient to be released by death than to try to relieve
him by surgery; cure is only a dream yet!
What Borges emphasized, on the eve of his long career as
a cancerologist, was the cacotelic nature of
cancer therapy. (Cacotelic, from Greek, means tending
to end badly). Gius 259,260 introduced
this term to drive home an important cancerologic lesson:
Operations intended to palliate (or even cure) may
sometimes make the patient worse than he was
initially. The modern cancerologists ought to take
a cue from the foregoing, and be publicly candid about
cancer therapy. But they wont. As one senior
scientist of the National Cancer Institute
confessed: It just doesnt pay to rock the
boat.44
The course of Ms. Schwartzs illness is not
available to the authors, but a fair guess can be made.
The possibility that for quite some time she must have
been blissfully free of any symptoms may be
realized from the recently established fact that in
leukemia, when there is complete remission a
patients bone marrow has at least a 1000 million
cells. 45,265 At some stage then her leukemia
could have returned from the silent to the clinical
stage. She could have had fever or a sore throat, or felt
weak or out-of-sorts; then came the blood counts and the
frightening diagnosis of leukemia was established.
What treatment must she have received? X-ray therapy and/
or chemotherapy, both greater enemies to many a normal
cell from head-to-foot, bowel to bone marrow.
Lenores leukemic count must have gone down, to the
academic satisfaction of her doctors, but so must have
her vitality, resistance and hemoglobin. Eventually,
Lenore succumbed, we do not know to what - the disease or
the treatment ! Many a leukemia gets controlled, but the
patient dies. Perhaps, it may be argued, had she lived,
or had had her leukemia now, her bone marrow, the seat of
the leukemic process, could have been first destroyed
completely by very heavy doses of toxic drugs and X-rays,
rendering it thus free of any cells, cancerous or
normal. The now-completely-defenseless patient could have
been grafted with bone marrow from another human to give
the patient white / red cells indispensable for survival,
as also hopefully to give donor-lymphocytes that would
act against any residual leukemia. But such superheroic
measures have proved tragically futile: twenty-four
leukemic cases were grafted. 46 In seven
cases, the graft failed to survive and the patients died
with aplasia or completely cell-less bone
marrow. In seventeen, the graft succeeded only to unleash
a vicious attack on the host - "the
graft-versus-host disease (GVHD)" which is
particularly severe in man46 - to kill
thirteen patients, ten in no time, two after some time,
and one a little later. The remaining four with
successful graft died with controlled; GVHD and
recurrent leukemia. The foregoing problems reported 46
in 1969 remain essentially unchanged today. 272-275
The saga39 of John Gunther Jr. is too
well-known to be described here. The brave boy was
treated with the most advanced allopathic and the most
hopeful naturopathic measures, but to no avail. The fault
wasnt with the treatment but with the cancer. All
brain cancers, even when they appear benign
to the microscopists have, what Willis20
calls, a wide field of origin. You remove it
at one place, and the next one grows for recognition, and
may be removed. In the end, the cancer wins, for want of
sacrificeable brain.
The true-to-life stories above may appear grim and
selective. One could as well have picked up eminent
people who did very well - pathologist-author Boyd,
Alexander Solzhenistyn, Sigmund Freud, John Wayne. But
the essential sequence of events remains the same,
whether the cancer is benign or otherwise. The most
important moral, if there may be any, of the above
accounts is that cancer is mercifully quiet and
unobtrusive for many years after its inception. And there
lies the benignancy of this malignant process.
There are some more human issues confounded by the
seeming vagaries of cancer. Why, me when I never
smoked and why not my friend who always did? Cancer
affects more-or-less a fixed percentage of the herd, and
it all depends where one gets caught in this probability
distribution. Of those who get it, the age at which
cancer occurs is normally distributed so that the
one gets it at 19, the other at 39 and the third at 93.
Such distribution holds true both for overall cancer and
for cancer at one particular site.
Some cancers allow a longer lease of life, with no
treatment or minimal treatment while others, of the same
histological variety, prove rapidly fatal despite timely
and adequate treatment. The secret of this lies in the
cancer itself, the survival-time itself being normally
distributed, thus accounting for the early death of
Karmofsky the cancer-specialist, and a long active life
for John Wayne, the Hollywood hero, both having had
cancer of the lung. Such unpredictable autonomy of
cancers has led cancerologists to classify, albeit a posteriori,
cancers as good, and bad, the former amenable to any
treatment, the latter to none.3 In a larger
perspective, the goodness or badness resides not
so much even in cancer itself, as much as in the
helplessly unpredictable nature of any individuals
biological trajectory.
What Makes Cancer Incurable?
The real enemy of
cancer cure is not the cancer itself, but the adjacent
normal cell, waiting for its turn to grow cancerous.
In cancerologic parlance, this process of normal cell
joining the cancerous troop is called recruitment.
The cancerous army thus can potentially become as big as
that of the normal cells in the body. This simple fact
rules out the cancerologists dream of The
Last Surviving Cancer Cell: The Chances of Killing
it.47 That is not all. While
surgerys fault lies in spreading 246,247
a cancer which was localized, X-ray therapy 6,248.249
and chemotherapy 6,8,15,101,102,250 are
agencies recognized for their ability to induce normal
cells to cancerate faster: The carcinogenic
activity of many of our chemotherapeutic agents is now
under advisement. 250 Chemotherapy can
render 251 berserk a benignantly behaving
malignancy and be effective to the point of being lethal:
The aggressive chemotherapeutic approach used ...
is often lethal to the patient with LRE (Leukemic
Reticolo-Endotheliosis, a type of leukemia).252
The only human cancer that does not present this
Damoclean demeanor of recruitment is the rare gestational
choriocarcinoma that occurs in women following pregnancy.
But this is so, because it is a cancer
transferred20 from the fetus to
the mother, thus not being autochthonous, or springing
from the mothers own tissues. Naturally such a
cancer allows a complete cure, for after the last
cancer cell, there are no normal cells to recruit.
This is, as yet, the solitary triumph of cancer
chemotherapy, for reasons that reside exclusively in the
cancer.
