Cancer disease

                            Cancer disease

Cancer disease

Cancer disease (medical term: malignancy growth) is a class of diseases in which a group of cells undergo uncontrolled growth (division beyond normal limits), disease attack (destruction and invasion of nearby tissue) and sometimes mutation or metastasis. (Spreads to other parts of the body through lymph or blood).
 These three chronic symptoms of cancer differentiate it from a benign knot (tumor or tumor) that is self-limited, not invasive, or does not show metamorphosis. Most cancer forms a knot or tumor, but some, such as blood cancer (leukemia) does not form a knot. The branch of medicine that deals with the study, diagnosis, treatment and prevention of cancer is called oncology or oncology

Cancer can affect people of all ages, even the fetus, but the risk of most varieties increases with age

Cancer disease

[1] Cancer accounts for 13% of the cause. 
[2] According to the American Cancer Society, During 2008, 6 lakh people died due to cancer all over the world.
 [3] Cancer can affect all animals.

Nearly all cancer cells are caused by abnormalities in the genetic material. 

[4] These abnormalities can be caused by carcinogens or carcinogens (cancer causing factors) such as tobacco smoking, radiation, chemicals, or infectious factors. Other genetic abnormalities causing cancer may sometimes be due to an error in DNA cancer replication (DNA) replication, or may be inherited and thus present in all cells since birth.

The heredity of cancer is generally affected by the complex interactions between carcinogens and the nutrient genome. Newer aspects of genetics of cancer pathogenesis such as DNA (DNA) methylation and microRNA (RNA) are increasingly gaining importance.

Cancer disease

Genetic abnormalities found in cancer usually affect two common classes of genes. Cancer-promoting tumors are typically active in cancer cells, giving new properties to those cells, such as increased growth and division than normal, protection from programmed cell death, lack of normal tissue limits, and diverse tissue environments. Ability to be installed.

The knot suppressor genes are then inactivated in cancer cells, resulting in a decrease in normal function of those cells, such as correct DNA replication, control of the cell cycle, orientation and adhesion within tissues, and Interaction with protective cells of the immune system. 

Typically, a pathologist has to undergo a histological examination of a tissue biopsy specimen to diagnose it, although early signs of malignancy may be signs of radiation-visual deprivation.


Cancer disease

Most cancer diseases can be treated, some can be cured, depending on the particular type, condition and condition of the cancer.
 Once diagnosed, cancer can be treated with a combination of surgery, chemotherapy and radiation therapy. With the development of research, treatments for various varieties of cancer are becoming more specialized. 

Significant progress has been made in the development of targeted therapy drugs that act specifically on detectable molecular abnormalities in the specific knot and damage in normal cells. She lowers Early diagnosis of cancer patients is strongly influenced by the type of cancer, as well as the condition and extent of the disease. In addition, histological classification and the presence of specific molecular markers can also be helpful in early diagnosis of the disease and in determining individual treatment.
