Cancer is a term used to
refer to malignant tumours. Tumours are cells in a tissue which grow
uncontrollably. Tumours can be Benign or malignant. Benign tumours grow and
remain in their tissue of origin whereas malignant tumours grow and spread to
other tissues thereby hindering their functions. The cancer cells are developed due to the
activation of abnormal genes called the ‘oncogenes’. Cancer can occur at any
age and in any part of the body and due to several reasons.
Cancers are caused
by genetic as well as environmental factors – Heredity, Ionizing radiations
such as X-rays, gamma rays, UV rays etc., Chemical substances like benzene and
asbestos (carcinogens), estrogens, viruses, stress and age are some of the
causative factors.
Diet and cancer are associated. Almost all cancers
(80–90%) are caused by environmental factors and of these; 30–40% of cancers
are directly linked to the diet. There is also a significant relation
between lifestyle (including food consumption) and cancer prevention.
The objectives of nutritional therapy are to meet the increased
metabolic demand of the diseased condition and prevent catabolism as much as
possible, and to alleviate symptoms resulting from the disease and its
treatment through adaptation of food and feeding process.
Following are the
nutritional requirements in cancer:
