Cancer is a generic term for a large group ofdiseases that can affect any part of the body. Other terms used are malignanttumors and neoplasms. One defining feature of cancer is the rapid creation of
abnormal cells that grow beyond their usual boundaries, and which can then
invade adjoining parts of the body and spread to other organs. This process is
referred to as metastasis. Metastases are the major cause of death from cancer.
Cancer encompasses a class of diseases characterized by uncontrolled cell proliferation
that can affect all organs. In metastasis, cancer cells multiply and travel
through blood and the lymph system to the rest of the body. Cancer in any form
remains a dreaded diagnosis, not just because of the looming shadow of death,
but also due to the severe side-effects of allopathic treatments like
chemotherapy and radiation. Having cancer doesn't mean you have to lose hope.
The good news is that cancer is now increasingly treatable. With the
advancements made in cancer research many cancers can now be cured while many
others can be controlled. If cancer can’t be controlled, symptoms can be
relieved to make life more comfortable. He earlier cancer is diagnosed and
treated, the better the chance of its being cured. Some types of cancer -- such
as those of the skin, breast, mouth, testicles, prostate, and rectum -- may be
detected by routine self-exam or other screening measures before the symptoms
become serious. Most cases of cancer are detected and diagnosed after a tumor
can be felt or when other symptoms develop. In a few cases, cancer is diagnosed
incidentally as a result of evaluating or treating other medical conditions.
Surgery is the mainstayfor the treatment of gastric cancer. Subtotal gastrectomy is the preferred
modality in distal cancers and total or proximal gastrectomy is preferred in
proximal cancers. A tumor-free resection margin of at least 4 cm is needed for
the adequacy of the surgery. Oral cancer ranks in the top three of all cancers
in India, which accounts for over thirty per cent of all cancers reported in
the country and oral cancer control is quickly becoming a global health
priority. This paper provides a synopsis of the incidence of oral cancer in
India by focusing on its measurement in cancer registries across the country.
Based on the International Classification of Disease case definition adopted by
the World Health Organization, and the International Agency for Research on
Cancer, this review systematically examines primary and secondary data where
the incidence or prevalence of oral cancer is known to be directly reported.
