today we will talk about bad friend ever  it called CANCER

It is a group of more than 100 different diseases

 It can develop almost anywhere in the body

OK 

Let,s talk about the begins

Cells are the basic units that make up the human body. Cells grow and divide to make new cells as the body needs them. Usually, cells die when they get too old or damaged. Then, new cells take their place

;Doctors divide cancer into types based on where it began. Four main types of cancer ar

Carcinomas

Sarcomas

Leukemias

Lymphomas

As a cancerous tumor grows, the bloodstream or lymphatic system may carry cancer cells to other parts of the body. During this process, known as metastasis, the cancer cells grow and may develop into new tumors

One of the first places a cancer often spreads is to the lymph nodes. Lymph nodes are tiny, bean-shaped organs that help fight infection. They are located in clusters in different parts of the body, such as the neck, groin area, and under the arms

Cancer may also spread through the bloodstream to distant parts of the body. These parts may include the bones, liver, lungs, or brain. Even if the cancer spreads, it is still named for the area where it began. For example, if breast cancer spreads to the lungs, it is called metastatic breast cancer, not lung cancer

It is a situation people often fear: sitting in the doctor's office and hearing the word “cancer.” People diagnosed with cancer often say they were stunned when they heard the news and unable to process what was said afterward. After the initial shock, it is important to learn about what comes next. Consider the following steps to learn about your diagnosis, find treatment, and cope

The stage of a cancer does not change over time. If the cancer comes back or spreads to another part of the body, the more recent information about the size and spread of the cancer is added to the original stage.

Sometimes, a doctor might “restage” a cancer to determine how well a treatment is working or to get more information about a cancer that has come back after treatment. This process uses the same staging system described above. Usually some of the same tests that were done when the cancer was first diagnosed will be repeated. After this, the doctor may assign the cancer a new stage. The doctor then adds a lowercase “r” before the new stage to show that it is different from that of the first diagnosis. However, this is not common
