CANCER ?

Here we first discuss what is cancer then we describe most common cancer types of the world.Cancer may be a term used for diseases during which abnormal cells divide while not management and are ready to invade alternative tissues. Cancer cells will unfold to alternative components of the body through the blood and humor systems. Cancer is not only one illness however several diseases. There are quite one hundred differing types of cancer. Most cancers are named for the organ or sort of cell during which they begin - for instance, cancer that begins within the colon is named colon cancer; cancer that begins in melanocytes of the skin is named skin cancer. Cancer varieties are often classified into broader classes. the most classes of cancer include:

    A.      Carcinoma - cancer that begins within the skin or in tissues that line or cowl internal organs. There are variety of subtypes of malignant neoplastic disease, together with glandular carcinoma, basal cell malignant neoplastic disease,squamous cell malignant neoplastic disease, and shift cell malignant neoplastic disease.

   B.      Sarcoma - cancer that begins in bone, cartilage, fat, muscle, blood vessels, or alternative connective or certificatory tissue.

    C.      Leukemia - cancer that starts in blood-forming tissue like the bone marrow and causes giant numbers of abnormal blood cells to be made and enter the blood.

   D.      Lymphoma and metastatic tumor - cancers that begin within the cells of the system.

  E.       Central system cancers - cancers that begin within the tissues of the brain and neural structure.

Origins of Cancer:

All cancers begin in cells, the body is basic unit of life. to grasp cancer, it is useful to grasp what happens once traditional cells become cancer cells. The body is created of many sorts of cells. These cells grow and divide during a controlled thanks to turn out additional cells as they are required to stay the body healthy. once cells grow old or broken, they die and are replaced with new cells. However, generally this orderly method goes wrong. The genetic material (DNA) of a cell will become broken or modified, manufacturing mutations that have an effect on traditional cell growth and division. once this happens, cells do not die once they ought to and new cells kind once the body does not would like them. the additional cells might kind a mass of tissue referred to as a neoplasm. Not all tumors are cancerous; tumors are often benign or malignant.

  1.       Benign tumors are not cancerous. They will usually be removed, and, in most cases, they are doing not come. Cells in benign tumors do not unfold to alternative components of the body.

   2.       Malignant tumors are cancerous. Cells in these tumors will invade close tissues and unfold to alternative components of the body. The unfold of cancer from one a part of the body to a different is named metastasis. Some cancers do not kind tumors. for instance, leukemia may be a cancer of the bone marrow and blood.
