What is cancer?


Containing nucleus of each cell in the human body to oversee and genes controlling cell functions and work and food and death and division, and each cell a pattern of life determined by a set of genes for managing the division or aging and cell death and called this group Genes Bmorthat death, or apoptosis.
And control the work of these genes responsible Morttin either divide or multiply and stop and stop this proliferation.

Neoplasms gene active growth and reproduction and division
Inhibiting tumor gene and the gene that prevents the tumor and a set of these genes work on a regular basis and are compatible to ensure the safety and function of cells and tissues is a specific program for each fabric example, oversees gene on the fabric of the lining of the uterus to be changed every 28 days and the fabric is not renewed after The birth of the gene, we find that non-oncological job
These things happen in the event of the integrity and functioning of genes, but what happens if someone's work for this gene defect to the gene increased the work of oncological or interruption of the gene ballasts work?
The answer would be a tumor.
Valorem is the proliferation of indiscriminate and uncontrolled cell to cell loses its ability to death succeeding in all directions without the presence of Ilgmeha or limit their reproduction. But this tumor was not necessarily caused malignant needs to be some changes in the structure of the cell to turn into a tumor and the tumor is malignant in a modest start in place, with the passage of time and intensity as Kbatth begin to deploy and expand and move to areas far giving Anakail Neoplasms, which means its time to progress in the tumor and the difficulty and complexity of treatment.
Valsrtan if not start at once but there are several stages of going through these stages and need time may extend for years, and if cancer is a disease affecting genes, leading to cell proliferation and this does not mean that necessarily hereditary disease.

Causes cancer

The real reasons leading to cancer is still unknown to some extent, but there are factors that help create or cancer and these factors are:
A. Genetics: The most common cancers known and not transmitted through genetics but individual cases have nothing to do with heredity, but the research demonstrated the role of genetics in some tumors and tumor Oormp most important products in the eye, which is often passed from father to sons and not necessarily to all And is affecting both eyes
Albulyat Alcolnip disease transmitted by the family and children to turn to Colon cancer.
B. Smoking: smoking called around 3000 article containing several articles have a direct relationship with cancer is the most important of these materials is also known as Abannsberin smoking cause significant variability towns especially skin color transformation from respiratory functioning respiratory skin to cover just do not have any work and this change is Change the cancer and need not only one step to become a cancer.
T.. The nature of food: Studies conducted on the relationship of food to some types of food and alcohol Caldsm Baltohib cancer, particularly cancers of the stomach and intestine, while vegetables and legumes and fiber reduce its incidence.
Th. Custodians Alraahp (viruses): We have found a relationship between some Alhamat Alraahp and some types of cancer, are:
Epstein-Barr meat linked to the emergence of nasal pharynx cancer in China and to Imfuma Birkett in tropical Africa
Fever Allae simple model 2 (Alheirbs) have a role to the emergence of cervical cancer
Hepatitis model fever b role in liver cancer.
C. Sexual practices:
Noted an increase in the incidence of cervical cancer after the spread of sexual freedom and the use of antiretroviral pregnancy and multiple sex partners also noted the increased risk of this type of cancer if the girl began their sexuality early also found a relationship between anal cancer and abnormal sexual practices.



H. X:
There is a link between radiation and skin cancers and leukemia and thyroid gland.
Kh. Geographical distribution: observed increase in some types of cancers in parts of the world, and I have said it before in other regions
D. Occupation and pollution: there are carcinogenic substances to humans, whether in business or in the environment co
ntaminated

Susceptibility to tumors

Symptoms of a potentially cancer
Possible through attention to these symptoms and review the doctor detect many tumors early and to the increase in lines of treatment and recovery and should be noted that these symptoms are not necessarily the symptoms of the disease and malignant, but at the same time warning may be a slag and the first symptoms are:
A. Lack of unintentional weight loss of more than 10% of the weight in 6 months
B. Change in bowel habits or urinating
T.. Difficulty swallowing or indigestion conversation.
Th. Ceylon or abnormal bleeding on top of the body.
C. Mass or thickening anywhere in the body, especially breast cancer in women.
H. Change in color or size or grain-free.
Kh. Hoarseness or annoying cough does not respond to treatment, especially if accompanied with the blowing of blood.
D. Ulceration does not respond to treatment during the 20 days
Y. Night sweats prolific and unnatural.

Stage tumor
And reflect on the progress and growing tumor and therefore to identify and warned it is necessary to know the stage of the tumor before starting treatment to determine quality. And that reflects the advanced stages of warning for the bad response to treatment and recovery, unlike the early stages. And to determine the stage of the tumor should be obtained much information on the scourge and infected lymph nodes and distant and transfer classified information to the TNM classification adopted universally, where T is the first letter of TUMOR meaning intended by the tumor and the tumor size and breadth and the greater the tumor Evil warning. The N is the first letter of NODE meaning intended by the contract and injury lymph nodes and the greater the number of groups affected by the contract warning and worse and finally M is the first letter of ,,,,stesis meaning intended by the transition and transfer away and transmission and means far-warning Bad as these three data set warning and treatment.

The spread of tumors
Malignant tumors has the advantage of its own and is the transition and spread to other areas in which they were and to be leaving some tumor cells neoplasms original and moving with the blood or lymphatic vessels and settle elsewhere and begin to reproduce. And there tumors more likely than others to move in very early and can precede the symptoms of the original tumor transition Veshko injured him, and upon examination found to be directed towards the transmission of the tumor, which arose from it. There are certain areas and move according to tumor type and where it originated and perhaps the nearby lymph nodes around the affected area are the most vulnerable of the transition and the lung and liver is one of the areas chosen for many cancers, it can, but the transition is more serious is Transfer to the brain that may put pressure on the sensitive date centers serious implications may lead to death, especially if the transition to the Center for breathing.
And put forward some tumors and common areas, it can be selected more than others.
Type of cancer: lung
More places of transition: pleurisy - fair - the lymph glands - the liver - bone - the brain - adrenal - the fancy of the region
--------------
Type of cancer: breast
More places of transition: the contract axillary (armpit lymph nodes under) - lung - bones - the liver - the brain.
