Medical Sciences India - INTRODUCTION

All India Institute of Medical Sciences was established by an Act of Parliament of 1956, as an autonomous establishment of national importance and its objectives and functions were outlined. By virtue of this Act, the institute awards its own medical degrees, diplomas and different educational distinctions. The degrees and diplomas awarded by the institute underneath the All India institute of Medical Sciences Act are recognized medical qualifications for the aim of the Indian Medical Council Act, are deemed to be included within the initial schedule of that act entitling the holders to constant privileges as those connected to the equivalent awards from different universities of India.


The Institute may be a residential university during which the school members, workers and also the students continue to exist campus. There are eight hostels for undergraduate students (6 for boys and a pair of for girls) with a capability to accommodate 850 students. There are separate hostels for the postgraduate students. The hospital has 1560 beds as well as the beds in Paying wards.

The prime concern of the Institute is to develop patterns of teaching in undergraduate and postgraduate medical education in all the branches therefore on demonstrate a high commonplace of medical education to any or all medical faculties and allied establishments in India. the opposite necessary objectives of the Institute are to collect in one place academic facilities of the very best order for the coaching of personnel in all the necessary branches of health activities and to achieve self-sufficiency in postgraduate medical education. the academic principles and practices being adopted here are those that are the simplest suited to the wants of the country. Adaptation of education to satisfy the issues of community health may be a major preoccupation. to the present impact the Institute has been making an attempt to initiate a model academic program that is undertaken within the Ballabgarh Community Development Block in collaboration with the Haryana Government. The Institute has additionally been in a position been able to initiate model academic programme in Community drugs at the urban field follow space in Malviya Nagar, New Delhi. stress is laid on the active learning method and on the cultivation of scholarly habits and scientific strategies.

The first batch of undergraduate medical students was admitted to the Institute within the year 1956 and since then the Institute has been admitting fifty students each year to the M.B.B.S. Course. the quantity of scholars to the present course is kept comparatively tiny to confirm an adequate teacher student ratio. The undergraduate curriculum is consistently the topic for discussion at the school and workers Council levels and needed changes within the curriculum are led to, off and on so as to evolve a pattern that is that the most fitted for the Indian wants and conditions.

The undergraduate medical students get sufficient impetus for higher studies because the institute provides facilities for postgraduate degrees in most the branches of medical sciences. At present, the Institute is awarding post-graduate degrees in concerning forty five totally different specialization.

All India Institute of Medical Sciences that may be a leading on-line education portal provides a platform where students or medical aspirants will have on-line tutorials for competitive exams like AIIMS, AIMPT, AFMC etc. The portal intends to supply an elite professional panel, comprising Medical students, graduates and medical coaching skilled who have a standard passion for medical Entrance exams specifically and science normally. The panel can offer on-line steerage to students showing for the AIIMS exam. the largest asset of the venture is that it's free, no subscription value either! This comes as a huge-advantage to the coed community who has been looking for personalised facilitate, however couldn't afford it because of prices or demographics. It additionally breaks all geographic barriers to collect a number of the simplest brains within the business to assist nurture succeeding generation.

What Causes Cancer ?

Causes of Cancer

Cancer develops over several years and has many causes. Several factors both inside and outside the body contribute to the development of cancer. In this context, scientists refer to everything outside the body that interacts with humans as the “environment.”

Factors Outside the Body (Environmental Factors)

Exposure to a wide variety of natural and man-made substances in the environment accounts for at least two-thirds of all the cases of cancer in the United States. These environmental factors include lifestyle choices like cigarette smoking,excessive alcohol consumption,poor diet,lack of exercise, excessive sunlight exposure,and sexual behavior that increases exposure to certain viruses.Other factors include exposure to certain medical drugs, hormones, radiation, viruses, bacteria, and environmental chemicals that may be present in the air, water, food, and workplace. The cancer risks associated with many environmental chemicals have been identified through studies of occupational groups that have higher exposures to these chemicals than the general population. The importance of the environment can be seen in the differences in cancer rates throughout the world and the change in cancer rates when groups of people move from one country to another. For example, when Asians, who have low rates of prostate and breast cancer and high rates of stomach cancer in their native countries, immigrate to the United States, their prostate and breast cancer rates rise over time until they are nearly equal to or greater than the higher levels of these cancers in the United States. Likewise, their rates of stomach cancer fall, becoming nearly equal to the lower U.S. rates. Lifestyle factors such as diet, exercise, and being overweight are thought to play a major role in the trends for breast and prostate cancers, and infection with the Helicobacter pylori bacterium is an important risk factor for stomach cancer. Recently, the rapid rise in the rates of colorectal cancer in Japan and China suggests an environmental cause such as lifestyle factors. Different environmental exposures are linked to specific kinds of cancer. For example, exposure to asbestos is linked primarily to lung cancer, whereas exposure to benzidine, a chemical found in certain dyes (see page 17), is associated with bladder cancer. In contrast, smoking is linked to cancers of the lung, bladder, mouth, colon, kidney, throat, voice box, esophagus, lip, stomach, cervix, liver, and pancreas.

Factors Inside the Body

Certain factors inside the body make some people more likely to develop cancer than others. For instance, some people either inherit or acquire the following conditions: altered genes in the body’s cells, abnormal hormone levels in the bloodstream, or a weakened immune system. Each of these factors may make an individual more susceptible to cancer. One of the ways scientists know that genes play an important role in the development of cancer is from studying certain rare families where family members over several generations develop similar cancers. It appears that these families are passing on an altered gene that carries with it a high chance of getting cancer. Several genes that greatly increase a person’s chance of developing certain cancers (e.g., colon, breast, and ovary) have been identified. Only a very small percentage of people in the general population have abnormal copies of these genes. Cancers caused by these genes, known as familial cancers, account for only two to five percent of all cancers. Gene alterations may also contribute to individual differences in susceptibility to environmental carcinogens (cancer-causing substances). For instance, people differ in their ability to eliminate cancer-causing agents from their body to which they have been exposed, or to repair DNA damage that was caused by such agents. These gene alterations may also be passed on in families and account for higher rates of cancer in these families. Higher rates of cancer in families may also be related to shared environmental exposures like diet or exposure to carcinogens at work One of the main objectives of a growing field in cancer research called molecular epidemiology is to identify gene alterations that increase or decrease a person’s chance of developing cancer after an environmental exposure. Interaction of Environmental Factors and Genes Environmental factors such as viruses, sunlight, and chemicals interact with cells throughout our lives. Mechanisms to repair damage to our genes and healthy lifestyle choices (wearing protective clothing for sun exposure or not smoking) help to protect us from harmful exposures. However, over time, substances in the environment may cause gene alterations, which accumulate inside our cells. While many alterations have no effect on a person’s health, permanent changes in certain genes can lead to cancer. The chance that an individual will develop cancer in response to a particular environmental agent depends on several interacting factors—how long and how often a person is exposed to a particular substance, his/her exposure to other agents, genetic factors, diet, lifestyle, health, age, and gender. For example, diet, alcohol consumption, and certain medications can affect the levels of chemicals in the body that break down cancer-causing substances. Because of the complex interplay of many factors, it is not possible to predict whether a specific environmental exposure will cause a particular person to develop cancer. We know that certain genetic and environmental factors increase the risk of developing cancer, but we rarely know exactly which combination of factors is responsible for a person’s specific cancer. This also means that we usually don’t know why one person gets cancer and another does not.
