A summary of what
The World Health Organisation (W.H.O.) have discovered about cancer
from scientific research: Cancer is largely preventable: by stopping
smoking, providing healthy food and avoiding the exposure to carcinogens.
Some of the most frequent cancer types are curable by surgery,
chemotherapy or radiotherapy.
The chance of cure increases substantially if
cancer is detected early.
Quality of life of cancer patients and their
families can be greatly improved by the provision of palliative
care.
Cancer control is a public health approach aimed
at reducing causes and consequences of cancer by translating our
knowledge into practice.
Recommendations from the World Health Organisation
concerning cancer include action in the following areas:
minimising or eliminating exposure to cancer
causes
reducing individual susceptibility to the effects
of these causes
serving the greatest public health potential
identifying the most cost-effective long-term
cancer control
tobacco control
obesity control
control of composition of the diet
control of consumption of alcoholic beverages
The World Health Organisation sees cancer prevention
programmes as part of integrated, national strategies. The risks
they identify for cancer above are common to all noncommunicable
diseases including heart, diabetes and respiratory problems. Prevention
programmes for all chronic diseases are able to use the same surveillance
and health promotion techniques. According to WHO recognised causes
of cancer include:
occupational and environmental exposure to a
number of chemicals
links between a number of infections and certain
types of cancer
parasitic infection schistosomiasis
exposure to some forms of ionising radiation
excessive ultraviolet radiation
W.H.O. treatment priorities
Early detection improves chances of survival,
but WHO stress ‘only when linked to effective treatment’.
The WHO want to increase our awareness of the signs and symptoms
of cancer and help set up regular screening of apparently healthy
individuals.
Accurate diagnosis of cancer is the first step
to effective management. Care of cancer patients starts with recognition
of some kind of abnormality in the body, followed by a visit to
a health care facility for diagnosis. Once a diagnosis is confirmed
then the disease is ‘staged’. The patient might be
referred to a specialist cancer treatment centre.
Orthodox treatment for the cancer is likely to
involve a mixture of chemotherapy, radiation therapy, hormonal
therapy and surgery. The primary objectives of cancer treatment
are: cure, the prolongation of life and improvement of the quality
of life.
Survival rates
Survival rates in standard treatments vary according
to the variety of cancer. For example the advanced treatment of
cancer of the uterine corpus, breast, testis, and melanoma may
produce a 5-year survival rate of 75% or more. Survival rates
in cancer of the pancreas, liver, stomach, and lung are generally
less than 15%. Because of the nature of cancer, many patients
present themselves with advanced disease. The only realistic treatment
for these patients is pain relief and palliative care. For insurance
purposes, cancer is often regarded as incurable.
