Cancer: A Review

Abstract

There are many causes of the origin of cancer like x -rays, but the irreversible injury of respiration is the main cause of the origin of cancer now the question arises what is an irreversible injury of cancer? In reversible cell injury the cell, it's component organelles start to disintegrate leading to the rupture of the cell. Cancer is the condition in which uncontrolled cell division occurs and the cancer cells damaging the genes.They directly start their cell cycle. They began their cycle with genetic changes which affect P-16 and cycling of cancer. The effect of inflammation which occurred due to the cancer is of important concern.In some kinds of cancer, the condition of inflammation is present before the occurrence of disease.Oppositely, there are some other kinds of cancer which are known as oncogenic changes cause an inflammatory microenvironment which encourages the development of cancer. Besides the origin inflammation of cancer. Now, cancer microenvironment which occurs due to inflammation of cells is indispensable in the process of neoplastic progression. In addition, cancer cells also play a role in some of signaling of the molecule in the innate immune system likes selectin also act as receptor for metastasis, invasion and migration. This research shows the static of cancer in the global area.Death occur b due to bladder cancer worldwide is 261000. Among these cases only 1/5th of the cases occurs in females. Similarly, death due to pancreatic cancer is 168.While death due to brain cancer and nervous system cancer are 127000 new cases of brain cancer while 95000 death occurs due to nervous system cancer. while cases of thyroid cancer are 87000. Melanoma is the cancer of skin, the cases of Melanoma 27.9 in men while 25 in woman DNA methylation is the best-known epigenetics. Cancer also occurs due tohypermethylation and identification of Increased methylation leads to the cancer suppressor genes which recently lead to the discovery of micro RNA by DNA methylation epigenetics also plays role in the therapy of cancer During the last seven months, computer-based program produced by linear programming has been used widely at Wisconsin University located in Madison use for the diagnosis of cancer related to breast. Nanotechnology is a field which covers diversedevices obtained from chemistry, biology. physics and engineering.These devicesis includes Nano vector, imaging contrast agent and anti-cancer drugs which are used for the treatment of cancer. Senescence defined as the changes of telomeres or with the help of different forms of stress eventsNeoplastic transformation events which plays a key role in the inhibition program of senescence.We know that the clear that cancer cell can be treated with chemotherapeutic
