LOW CALORIE DIETS/CANCER/LONGEVITY
Dr. Robert A. Good, president and director of Sloan-Kettering
Cancer Center in New York reported that extensive investigations
with laboratory animals have demonstrated that a low calorie diet
reduces cancer risk and prolongs life. By restricting calories
from the time of weaning, they were able to double or triple the
lifespan of the experimental rats. Dr. Good emphasizes that the
fact that for best results the caloric restriction must begin early
in life.
The incidence of malignancies in the experimental animals,
normally 90 percent in breeding females, and 60-80 percent in
unbred females dropped to zero.
"Everything that I have ever really understood in these mice is
directly applicable to man," says Dr. Good. "We already know that
females who are extremely overweight have 8 to 10 times the
incidence of endometrial cancer than females of normal weight."

APPENDECTOMY/CANCER
Patients who die of cancer, particularly carcinoma of the colon,
breast or ovary, or lymphoma or leukemia are twice as likely as the
normal population to have had an appendectomy. In most cases
studied the appendix had been removed during childhood or early
adulthood. Up until about the age of 30, the appendix is richly
endowed with lymphoid tissue, which researchers feel may be an
antibody producing tissue. For this reason, Dr. Howard Bierman,
director of the Institute for Cancer and Blood Diseases at Loma
Linda University School of Medicine suggests that persons who had
their appendix removed (for other than acute disease) before the
age of 30 be more carefully watched for signs of cancer.
Dr. Bierman reported that 42 percent of the persons in his study
dying of cancer of the col;on had undergone appendectomy, as had 62
percent of those dying with cancer of the breast and 84 percent of
those dying with cancer of the ovary. The average age for
appendectomy was 27; the average age at death was 55 years.

The use of milk, cheese, eggs and meat has been associated with the

Athletes who use androgenic anabolic steroids, such as

Physicians are now beginning to suspect that venereal warts may be

One of the arguments advanced to promote circumcision of males has

early maturity increase the risk of breast cancer, by lowering the
age at which girls begin their menstrual cycles. This would include

A study reported at the Fifth International Congress on Twin
Studies reveals that women who had their first menstrual period

who were older at their first live pregnancy were more likely to
develop breast cancer, as were women who had abortion, induced or

breast cancer were also more likely to have had an artificial

CHLORINATED WATER/CANCER
Epidemiologists are beginning to wonder if there is a relationship
between the use of chlorinated water and cancer. They feel that if
there is a relationship the risk is likely to be small, but when
one considers the number of people consuming chlorinated water even
a small risk may cause thousands of otherwise avoidable cancers in
a year's time.
Chlorine interacts with organic chemicals in water to form
chloroform, as well as other trihalomethanes (THM). Chloroform is
known to produce cancer in laboratory animals, and the THMS are
known to be mutagenic (capable of causing cell changes which may
lead to cancer). Early studies compared cancer incidence in areas
where chlorinated surface water was consumed with areas where the
people used untreated ground water. After adjustment for other
factors, increased rates of bladder, colon, and rectal cancers were
observed.
There have been six case-control mortality studies carried out in
the United States, and five of these six revealed increased risks
for bladder, colon, and rectal cancer in those drinking chlorinated
water. Some studies suggest that the risk may be doubled. (Health

FLUID INTAKE/BLADDER CANCER
Bladder cancer rates appear higher in urban populations than in

urine remains in contact with the bladder wall for longer periods

mineral, and insufficient quantities may lead to anemia. Excess
iron, however, may predispose the body to infection. Colon,

high body iron stores, and as iron stores increase the cancer
incidence also increase. The researchers suggest that
fortification of food with iron, and iron supplements other than in
anemic individuals may be unwise. Copyright Phylis Austin

studies demonstrate a positive relationship between lung cancer in
men and breast cancer in women, suggesting that a husband's smoking

SILICONE GEL IMPLANTS/CANCER
The Public Citizen Health Research Group has called on the Food and

testicular prosthesis silicone gel implants.
The Health Research Group wants the FDA to determine why Dow
Corning, the manufacturer of the implants, did not notify the FDA
of their studies revealing the carcinogenicity of silicone gel.
Many of the cancers are of the rapidly-spreading type.
Silicone gel apparently migrates through the envelope encasing it,

reconstruction using this material. (Public Citizen Health Research

radiation leukemia incidence decreased from fifty percent to four percent on a

ALLIUM VEGETABLES/STOMACH CANCER
The liberal use of allium foods (garlic, onions, scallions, Chinese chives)
apparently decreases the risk of stomach cancer. Laboratory animal studies have
demonstrated growth inhibition of several different tumor types when the animals
were fed allium vegetables. Scallions, garlic, and Chinese chives were felt to
be the most protective.
Several population studies have shown an association between onion intake and
reduced risk of stomach cancer. An area of Georgia known for its onion
production has about half the stomach cancer incidence of the remainder of the
state. Rates were three times lower in Japanese people living in Hawaii who
consumed onions about 21 times a month, when compared to those using them less
than eight times per month. In Greece those who used lots of onions had less
stomach cancer. Risk appears to decrease as intake increases.
Allium vegetables are known to have anti-bacterial and anti-fungal properties,
and may inhibit bacterial growth in the stomach.
It is felt that both tumor initiation and growth is inhibited by the substances
in these foods.
The consumption of sour pancakes (a fermented food), salty foods, moldy grain
foods, smoking, chronic gastritis, and gastric ulcer were all associated with
increased risk of stomach cancer. (Journal of the National Cancer Institute

EATING FREQUENCY/COLON CANCER
A Swedish study indicates the frequency of snack eating may be

Earlier, largely ignored studies, have suggested that each eating

LUNG CANCER/MEAT INDUSTRY
Studies from Denmark, Sweden, England and Wales have shown an

A study from Baltimore, Maryland, demonstrates an unusually high
incidence of lung cancer in men who worked in slaughterhouses,
chicken-slaughtering plants, meat-packing plants and the meat
department of supermarkets. This excess incidence was not related
to smoking. The researchers feel that workers may be exposed to
viruses which produce lymphoma or leukemia in animals, and to

PROSTATE CANCER/SURGERY
Prostate cancer is the most common cancer in U.S. males. Treatment
routines vary from one part of the country to another. The number
of radical prostatectomies performed increased nearly six times in
the time period of 1984 to 1990. A study from the Biomedical
Information Communications Center of the Oregon Health Sciences
University in Portland, Oregon, suggests that many men with
localized prostate cancer may benefit from watchful waiting, rather
than radical prostatectomy. They point out that vigorous treatment
may result in such unwanted effects as loss of control of the urine
and impotence, which may greatly reduce the man's quality of life.
Treatment of advanced prostate cancer may prolong life an average
of only about one year. The researchers conclude that in prostate
cancer patients older than 70 years of age watchful waiting is a
reasonable alternative. (Journal of the American Medical

CHLORINE/BREAST CANCER
There may be a relationship between trihalomethanes (THMs) which

Organochlorines, substances made from chlorine, may be
associated with breast cancer. Polyvinylchloride (PVC) is used in
many vinyl products, particularly plumbing materials. Some
pesticides also contain substances made from chlorine. Dioxin is a
chlorine byproduct.
Organochlorides tend to accumulate in fatty tissue, such as is
found in the breast. They depress the immune system, cause cell
mutations, and hinder the body's natural ability to control cell
growth.
Population studies have shown that women who are occupationally
exposed to organochlorines have higher breast cancer rates. Breast
cancer patients were found to have higher levels of organochlorides
in their breast tissue, and breast cancer rates in Israel dropped
after the use of pesticides containing organochlorides was reduced.
