Cancer
Cancer is the disease resulting from the failure of immune system. Immune system is constituted of tissues, organs and vessels. The immune system works on the principle of recognition of self and non self. It works against the foreign attackers causing inflammation and injuries. Sometimes the cells do not identify the cancer germs as the foreign and let them grow and make network in the body. A healthy immune system can quickly identify the cancer cells before it starts showing abnormal division and function. However, when immune system is not as organized as the cancer cells are; the cells start multiplying and causing the result of the birth of number of abnormal cells which cannot be immune by the system. This only happens where the immune army is not as well fed, efficient and defensive as the cells causing cancer are.
In the last few decades it was thought to be the result of the deficiency of immune system. Yet, now we all know that this not mere the weak immune system; there can be many other factors, one of them is genetics. People carry cancerous cells in the recessive form from generations to generations and stay healthy. At any stage of life, these cells get stimulated and start showing abnormality. Here immune system may not respond as quickly as it should be. The reason of this is that these cells have been coexisting with the system and had camouflaged them. Immune system gets difficulty and does not recognize the messages.
Another is the genetic transfer of cancer cells from parent to child. However, it is not necessary that one or the both parents must be patients of cancer. The reason is again the activeness of the cells in fetus while these were non active in the parental genes.
People becoming victim of cancer can also because of the reason of the smoke and alcohol. Smoke and alcohol are the most cancer risk factor. According to an American Company, tobacco almost damages each and every human organ. Smoke becomes the reason of cancer in almost30% of the population. In the last century; especially in the former 5 decades, cancer was known as the monstrous disease, the fear of which was killer. This is one of those diseases, the cure of which is still in progress and researches are being conducted at international and domestic level.
All researches agree on the fact that human body care and physical fitness reduce the chances of cancer, help in the improvement of healthy life and in some cases; these factors even strengthen the cancer survival. Taking a diet free of alcoholic products can keep you away from the cancer dangers. A complete care of human body and complete physical fitness keep you free of second and third hand smokers.
Having more than 2 drinks per day for many years can increase the chance of cancer of throat, mouth, liver, larynx and esophagus. Among drinkers, those who use tobacco face higher risk of cancer. Doctors always advise alcohol in moderation.
