Cancer wiki guide – Our body is composed of many types of cells. As these cells are needed by them, these cells divide and grow in a controlled way. But sometimes it happens that the body does not need any of these cells, yet they continue to grow. “Cancer wiki”

This abnormal development of cells is called cancer (which is usually produced from an abnormal cell) in which the cells lose normal control. Thus, a group of cells continuously increase uncontrolled, which attacks surrounding adjacent tissues, which reaches the distant parts of the body and spreads through the lymph or blood to other parts of the body. Cancer cells can grow in any tissue of the body.

As the cancer cells grow and multiply, they take the form of a group of cancer cells called tumors. These tumors attack nearby tissues and destroy them. Tumor can cause cancers or non-cancerous. Cancer cells can spread from one place to the entire body (metastases). “Cancer wiki”


Cancer Wiki – How Cancer Works and Spreads

Cancer cells develop from healthy cells in a complex process called fatal changes.

Cancer Initiation

The change in the cell’s genetic material is cancer. Changes in the genetic material of a cell can happen either by itself or by some agents or elements. These agents are Chemicals, Tobacco, Virus, Radiation and Sunlight. But it is not necessary that all cells are equally affected with these agents. A genetic defect in cells makes these agents susceptible to the body. Even long-term physical irritation can also make these agents susceptible to one cell.

Cancerous Growth

Some agents or agents (promoters) cause to grow in the development of cancer. These agents may also contain some substances or medicines available in the environment such as sex hormone testosterone which is used to improve sexual desire and energy in older men. Unlike carcinogens, these promoters themselves do not cause cancer. Instead, these promoters promote the growth of cancer-affected cells. These promoters have no effect on the cells in which the onset of cancer has not started.

Elements that cause some cancers cause cancer without the need of promoters. For example, ionizing radiation – which is mostly used in X-rays) can cause various cancers, especially sarcoma, leukemia, thyroid cancer and breast cancers.

How does Cancer Spread?

Spread Cancer

Spread Cancer

Cancer can grow directly in the surrounding tissues or spread to organs, whether they are away or nearby. Cancer can spread through the lymphatic system. This type of dispersal also occurs in carcinoma. For example, breast cancer usually spreads to the nearest lymph nodes in the vicinity and later it spread to other parts of the body. Cancer can also spread through blood flow. This type of spread is also found in sarcoma cancer. Cancer wiki.

Stages of Cancer

Cancer tissues can be divided into blood and blood forming tissues (leukemia and lymphomas) and “solid” tumors (solid mass of cells), often called cancer. Cancer can be carcinoma or sarcoma.

Leukemia and lymphoma are blood cancer. Leukemia is produced from blood-borne cells, in which bone marrow and immature white blood cells with high amounts of blood flow are displaced instead of normal blood cells. Cancer lymph nodes are expanded in lymphoma. Lymphoma often begins with lymph nodes but it can also be found in the adjacent, genital, stomach, chest or intestine.

Carcinoma is the most common type of cancer. In which cancer cells affect the internal and external parts of the body such as lungs, breast and stomach cancer. It starts with the epithelium tissue of the skin. Examples of carcinoma are cancer of the skin, lungs, colon, stomach, breast, prostate, and thyroid gland. Typically, people older than men are more carcinoma than carcinoma.

Tumors occurring in sarcoma tissues (tissues) are associated with each other. Common connective tissues include fat, blood vessels, nerves, bones, muscles, cartilage etc. Examples of sarcoma are – leiomyosarcoma and osteosarcoma (bone cancer). Typically, this cancer is higher in older people than older people.


Cancer Symptoms – Cancer wiki

When cancer cells are in very small form then the signs of cancer do not appear. But as the cancer grows, its presence can affect the surrounding tissues. Apart from this, due to some cancer the secretion of certain substances from the body or some cancers trigger immune responses, from which parts of the body which are away from the parts of the cancerous genus can also cause cancer symptoms.

Pain – Some cancers are painless before, but the initial symptom of some cancers can be painful, such as brain tumors, which lead to headache, and head, neck and anophthal cancers, which cause pain during swallowing. As the cancer increases, its first symptom is often uncomfortable, which can rapidly turn into severe pain with the spread of cancer. However, not all cancers cause severe pain. Likewise, the lack of pain does not guarantee that cancer is not spreading or spreading.


Bleeding – A small blood can come in the cancer because its blood vessels are fragile. Later, as the cancer grows and attacks the surrounding tissues, it can increase in a nearby blood vessel, causing bleeding. This bleeding can be mild and can be diagnosed with or not, it can be detected only with the test. This is often the case of early stage colon cancer. Bleeding in advanced cancer can be high, even this bleeding can be dangerous for life.


The place where cancer is, it determines bleeding. Bleeding may occur in the stool in the cancer associated with the digestive tract. Cancer associated with urinary tract can bleed in urine. Other cancers can cause blood in internal areas of the body. Bleeding in the lungs can cause a person to get blood in cough.


Blood clots – Some cancers produce substances that cause the blood to form in the body, mainly in the nerves of the legs. Blood clots in the nerves of the feet sometimes break down, which spread to the whole body which can be fatal for you. Extreme cloaking is common among people with pancreatic, lungs and other solid tumors and those with brain tumors.

Weight Loss and Fatigue – Typically, the person with cancer experiences weight loss and fatigue, which can further worsen this condition due to the increase in cancer. Some people have reported loss of weight despite good appetite. While some people may have difficulty in hunger or swallowing food. They can be very thin. People with advanced cancer often are very tired. If anemia develops, such people may lack fatigue or shortness of breath with little activity. Cancer wiki.


Swelling in the lymph nodes – As soon as the cancer begins to spread around the body, it can first spread to nearby lymph nodes, which is swollen. Inflammation lymph nodes are generally painless and may be hard or rubbish-like. If cancer studies are on stage, then these lymph nodes can get stuck in the skin above, trap them in layers of tissues or even in the middle.


Neurologic and muscular symptoms – The cancer can compress the nerve or spinal cord. It can be any of neurologic and muscular symptoms such as pain, weakness or change in cognition (such as tingling stimulation) etc. When cancer increases in the brain, it can be difficult to detect symptoms, but it can cause confusion, dizziness, headache, nausea, vision changes and seizures. Symptoms of neurologic can also be part of an irreversible syndrome.


Respiratory symptoms – Cancer can compress or block structures such as airway in the lungs, which can cause shortness of breath, cough or pneumonia etc. Breathing may also occur when the cancer causes the pleural effusion between the lungs and chest, causing bleeding or anemia in the lungs.Cancer wiki.


Causes of Cancer

Causes of Cancer

Causes of Cancer

Cancer is a comprehensive group of diseases and there are many reasons for it. Many genetic and environmental factors increase the risk of developing cancer. According to each biology and pathology, each cancer is of a different type. According to the World Health Organization (WHO), the following are common factors for cancer:


1. The Cause of Cancer is Genetic

Genetic changes due to cancer can be inherited from our parents. Some families have a significant risk of developing certain types of cancer. Sometimes there is a risk of a single gene causing it to grow. Abnormalities affecting serious gene (mutation) are known to contribute to the development of cancer. These genes produce proteins that regulate growth and change cell division and other basic cell properties.

An additional or abnormal chromosome can increase the risk of cancer. For example, people with Down syndrome have three copies of chromosome 21 rather than normal two copies. They have 12 to 20 times more risk of developing leukemia.


2. Age Related to Cancer

Some cancers such as Wilms tumors, retinoblastoma and neuroblastoma are especially in children. These cancerous septors are produced from gene mutations that either be inherited or occur during the development of the fetus. However, most other cancers are more common in adults, especially in older people. The growth rate of cancer is probably due to long-term contact with carcinogen.


3. Cancer Due to Environmental Factors

Many environmental factors increase the risk of developing cancer.

Risks are carcinogens in tobacco smoke to lung, mouth, throat, esophagus, and kidney and bladder cancer are increasing substantially. People who smoke also increase the risk of lung cancer.

Pollutants such as asbestos, industrial waste or cigarette smoke can increase the risk of cancer in air or water. Many chemicals are known to cause cancer. For example, exposure to asbestos can be the cause of lung cancer and mesothelioma (lung cancer). Staying in contact with pesticides is associated with some types of cancer (for example, leukemia and non-Hodgkin lymphoma). The reason for the development of chemicals and cancer has to come in contact with the chemical for a long time.

Radiation exposure is one of the main reasons for the development of cancer. Exposure of ultraviolet radiation is mainly due to sunlight which causes skin cancer. Ionization radiation is a special carcinogen. X-ray (computed tomography [CT] including) the use Aianaijheshn radiation and which of a series of tests using high doses of X-rays as they increase the risk of cancer. Exposure of radioactive gas radon (which is released from soil) increases the risk of lung cancer.

Many other substances are investigating possible causes of cancer, but more study is needed to identify those chemicals that increase the risk of cancer.


4. Cancer Caused by Diet – Cancer wiki

Foods eaten in the diet can increase the risk of cancer. For example, rich diet and fatness in unsaturated fat is associated with increased risk of colon, breast and possibly prostate cancer. People who drink large amounts of alcohol, head and neck, and enropagal are at high risk of developing cancer. Spicy food or excessive consumption of barbecue meat can increase the risk of colon cancer. People overweight or obese have a greater risk of breast cancer.



  1. Medical Treatments that Cause Cancer

Some medicines and medical treatments can increase the development of cancer. For example, estrogen present in oral contraceptives can increase the risk of breast cancer gradually, although this risk decreases over time. Hormone estrogens and progestins given to women during menopause (hormone replacement therapy) also increase the risk of breast cancer.

The level of extra estrogen promotes uterine cancer. Tamoxifen is a medicine used to treat breast cancer, which increases the risk of endometrial cancer. Long-term use of testosterone or other male hormone (androgen) can also increase the risk of liver cancer. Cancer treatment with some chemotherapy agents and radiation therapy can later increase the risk of developing other cancers. Cancer wiki.


6. Cancer Caused by Infections

Many viruses are known to cause cancer in humans and many other viruses are suspected to be cancerous. The human papilloma virus (HPV – human papilloma virus) is a major cause of cervical cancer in women and is one of the reasons for penile and anal cancer in men. HPV also causes some cancers of the throat. Hepatitis B virus or hepatitis C virus can lead to liver cancer. Some human retroviruses are due to the lymphoma and other cancers of the blood system. Some viruses cause a type of cancer in some countries, but in other countries there are other types of cancer. For example, epstein-bar virus causes burkitt lymphoma (a type of cancer) in Africa and nasal and pharyngeal cancer in China.

Some bacteria may also cause cancer. Helicobacter pylori which causes stomach ulcers can increase the risk of stomach cancer and lymphoma.


7. Inflammation Disorders Cause Cancer

Cancer wiki – Inflammatory disorders often increase the risk of cancer. Such disorders include ulcerative colitis and Crohn disease, which may result in colon cancer and bile duct cancers.
