What is Cancer? What Causes Cancer?

Cancer is a class of diseases characterized by out-of-control cell growth. There are over 100 different types of cancer, and each is classified by the type of cell that is initially affected.
Cancer harms the body when damaged cells divide uncontrollably to form lumps or masses of tissue called tumors (except in the case of leukemia where cancer prohibits normal blood function by abnormal cell division in the blood stream). Tumors can grow and interfere with the digestive, nervous, and circulatory systems, and they can release hormones that alter body function. Tumors that stay in one spot and demonstrate limited growth are generally considered to be benign.

More dangerous, or malignant, tumors form when two things occur:

1. a cancerous cell manages to move throughout the body using the blood or lymph systems, destroying healthy tissue in a process called invasion
2. that cell manages to divide and grow, making new blood vessels to feed itself in a process called angiogenesis.

When a tumor successfully spreads to other parts of the body and grows, invading and destroying other healthy tissues, it is said to have metastasized. This process itself is called metastasis, and the result is a serious condition that is very difficult to treat.
In 2007, cancer claimed the lives of about 7.6 million people in the world. Physicians and researchers who specialize in the study, diagnosis, treatment, and prevention of cancer are called oncologists.

What causes cancer?

Cancer is ultimately the result of cells that uncontrollably grow and do not die. Normal cells in the body follow an orderly path of growth, division, and death. Programmed cell death is called apoptosis, and when this process breaks down, cancer begins to form. Unlike regular cells, cancer cells do not experience programmatic death and instead continue to grow and divide. This leads to a mass of abnormal cells that grows out of control.

Genes - the DNA type

Cells can experience uncontrolled growth if there are damages or mutations to DNA, and therefore, damage to the genes involved in cell division. Four key types of gene are responsible for the cell division process: oncogenes tell cells when to divide, tumor suppressor genes tell cells when not to divide, suicide genes control apoptosis and tell the cell to kill itself if something goes wrong, and DNA-repair genes instruct a cell to repair damaged DNA.
Cancer occurs when a cell's gene mutations make the cell unable to correct DNA damage and unable to commit suicide. Similarly, cancer is a result of mutations that inhibit oncogene and tumor suppressor gene function, leading to uncontrollable cell growth.

Carcinogens

Carcinogens are a class of substances that are directly responsible for damaging DNA, promoting or aiding cancer. Tobacco, asbestos, arsenic, radiation such as gamma and x-rays, the sun, and compounds in car exhaust fumes are all examples of carcinogens. When our bodies are exposed to carcinogens, free radicals are formed that try to steal electrons from other molecules in the body. Theses free radicals damage cells and affect their ability to function normally.

Genes - the family type

Cancer can be the result of a genetic predisposition that is inherited from family members. It is possible to be born with certain genetic mutations or a fault in a gene that makes one statistically more likely to develop cancer later in life.

Other medical factors

As we age, there is an increase in the number of possible cancer-causing mutations in our DNA. This makes age an important risk factor for cancer. Several viruses have also been linked to cancer such as: human papillomavirus (a cause of cervical cancer), hepatitis B and C (causes of liver cancer), and Epstein-Barr virus (a cause of some childhood cancers). Human immunodeficiency virus (HIV) - and anything else that suppresses or weakens the immune system - inhibits the body's ability to fight infections and increases the chance of developing cancer.

What are the symptoms of cancer?

Cancer symptoms are quite varied and depend on where the cancer is located, where it has spread, and how big the tumor is. Some cancers

every disease there is no cure

Thousands of patients have been successfully cured simply by reading the Holy Qur'an at a free clinic in the city of Grozny, the sound of a statement of the Chechen presidential website on Wednesday.
"Since opening day, the Islamic Medical Center has received more than 60,000 patients. The majority of those who have come have been recovered from his illness. The clinic helped them to heal with non-traditional way, ie by reading the Holy Koran, "said the statement.
President Ramzan Kadyrov took part in celebrations on Tuesday to mark the first anniversary of the Medical Center. He was awarded Medal of Akhmad Kadyrov, who is the highest decoration in the Republic of Chechnya, to David Selmurzayev, head of the Islamic Center.
Selmurzayev Kadyrov also thanked for giving him a chance to build the Islamic Medical Centre.
After that, he gives a picture with the inscription of God of the gemstone to Ramzan Kadyrov on behalf of all employees Pengobatam Center.
The treatment center has had a very wide popularity since the first day of operation, said Kadyrov.
"Medical Center has been very popular not only among the population of this country, but also Muslims from other Russian regions and CIS countries," said Kadyrov.
In addition to President Kadyrov, the names of others who also attended the commemoration is Health Minister Shakhid Akhmadov, Grozny Mayor Muslim Khuchiev, and center Adam Shakhidov Imam Mosque.
In the medical history, medication Islamic or Arabic medicine refers to the Islamic civilization developed in the mid and written in Arabic. Latin translations of Arabic medical performance have a significant influence on the development of modern medicine.
In Islamic tradition, the roots of Islamic medicine can be traced back to the time of Prophet Muhammad, with a number of hadiths regarding treatment. Some friends said to have succeeded in treating certain diseases by following medical advice from the Prophet. The three well-known method of healing that never mentioned by him is honey, cupping, and cautery (burning the body to remove diseased tissue), although the Prophet is generally opposed the cautery unless it is handled according to the disease. According to Ibn Hajar Al Asqalani, Prophet Muhammad did not like the methods of cautery as painful and dangerous for the patient.
Although recognized by medical experts before such as Imhotep, Hippocrates, and Galen, the Prophet Muhammad seems to be the first recorded stating directly that every disease has a medicine, according to some hadith Bukhari, Sunan Abi Dawood, and Al Muwatta, which states that the Prophet said: , "No disease God created, but has he also created an antidote."
The belief that there is a cure for every disease encourage the Muslims in the past is to engage in biomedical research and find a cure for every disease they know. Many early writers of Islamic medical science which is a cleric and not a doctor, and famous traditional medical practice has opened in time of the Prophet, as mentioned in the Qur'an and Hadith.

cure the disease of HIV / AIDS

The world is always concerned about a virus called HIV / AIDS. Imagine, this virus can infect humans without detectable and can only be felt if it had stepped on an advanced stage of severe and lead to death.
While the spread of HIV / AIDS virus is so deadly is very spread to various parts of the country, cities and even villages, so far not yet found a drug that can actually cure the disease that attacks the human immune system.
Drugs that exist today are simply slow down the spread in the body of the patient, but did not heal completely. In addition to these weaknesses, the price is relatively expensive, difficult to be found, and have a high failure rate in the process of holding the spread of the virus. Especially after it emerged that these drugs have side effects for the Drinker.
