Cancer cells are aberrant cells which do not die after aging due to mutations in DNA which prevent them from dying normally. These are formed routinely in a normal person, but this is effectively curtailed by our immune system. Therefore these cells sustain and proliferate only when there is a favorable environment in our body that is either our immune system can't curtail them effectively or there is unhindered high intracellular oxidative stress in the form of free radicals which can damage DNA. In 2018, the Nobel Prize was awarded to James P. Allison and Dr. Tasuko Honjo in field of medicine, for their discovery on ways of activating the immune system to target cancer cells. This explains the role of good immune system to help prevent cancer, and also in treating cancers.
Any factor that causes mutations that prevent natural cell death, disturbing the fine balance between cell death and cell survival mechanisms causes Cancer. These may be genetic factors, environmental factors like smoking(both active & passive), alcohol, excessive radiation exposure, pollution (air, food, water), mental stress, lack of sleep, lack of physical activity, obesity, infections like HBV, HCV, HPV, EBV (Epstein-Barr virus) and improper diet in the form of taking excessive refined Sugars and flour; too much saturated animal fat, red meat, deep fried foods, etc. Apart from genetic factors where there is already a mutation in DNA, the above mentioned environmental factors cause excessive generation of free radicals in our cells causing oxidative stress upon cells -damaging DNA and thereby leading to mutations and cancer.
Coming to the preventive aspect, if there is a strong genetic factor prevalent, then the individual in question should consult a Physician, take advice and undergo periodic screening as advised if necessary. Avoid smoking, whether it is passive (or) active, avoid alcohol intake, and avoid exposure to unnecessary radiation. Air pollution risk can be reduced by improving tree coverage in the cities and towns. Every individual should have at least 45 minutes physical activity per day. Indians BMI (Body mass index) should be in the range of 19 to 23kg/m2 approximately. Tackle obesity with the help of raw diet and physical activity.
Consume foods which come from natural farms where usage of pesticides and chemicals is zero, avoid consuming packed frozen foods, avoid excessive use of carbohydrates because it causes high oxidative stress on cells; avoid using too much animal fat, deep-fried foods and red meat. Use millets and whole grains instead of refined sugar and flour. Millet contains more micronutrients, more fibre and less glycemic index. Try to consume thirty to fifty percent as raw vegetables, fruit and nuts. Daily meditation and Pranayam, which Americans call cardiac breathing synchronising exercise, reduces mental stress, thereby cellular stress with control of stress related hormones.
BASIS OF RAW DIET:
When we consume foods such as fresh fruits, vegetables, nuts, legumes and root vegetables which are alkaline in nature, these are broken into short chain fatty acids that contain prebiotic nutrients that nourish good bacteria in our gut which in turn decrease inflammation throughout our body, whereas refined sugars, flour and saturated animal fats create an acidic environment in our gut. Raw diet contains adequate amounts of micronutrients, and plenty of antioxidants like vitamin C, E and A, which in turn tackles oxidative stress.
In a nutshell, cancer can be prevented by combining a healthy diet with daily physical activity, adequate sleep; avoiding mental stress, having periodic screenings, avoiding smoking and alcohol and exposure to other carcinogens
