Cancer
The organs and tissues are made up of tiny building blocks called cells. Cancer is a disease of these cells. Cells in different parts of the body may look and work differently, but most breed in the same way.
The cells are constantly growing old and dying, and new cells are produced to replace them. Normally, cells divide in an orderly and controlled. If for some reason the process goes out of control, the cells carry out the division, developing into a lump called a tumor.
Cancer is a term for diseases in which abnormal cells divide without control and can invade other tissues. Cancer cells can spread to other parts of the body through the blood and the system node.
Brain Cancer
A brain tumor is a group or set of abnormally growing cells that are in or on the brain. In rare brain tumors in children may start in the brain or the spread in no other part of the body – some cancers that begin in other parts of the body may have cells travel to the brain and begin to grow there.

The more cigarettes smoked per day and the last to start smoking, the greater your risk of lung cancer. High levels of pollution, radiation and asbestos exposure can also increase risk. Cancer that forms in tissues of the lung, usually in the cells lining the airways. The two main types are lung cancer and non-small cell lung cancer cells.
In general, extending to different parts of the body more cancer slowly than small cell lung. Squamous cell carcinoma, adenocarcinoma and large cell carcinoma are three types of cancer non-small cell lung. The cell lung cancer also called oat cell cancer, accounts for about 20% of all lung cancers.

Cancer skin represents the most commonly diagnosed cancer, surpassing lung, breast, colorectal and prostate cancer. Cancer that forms in tissues of the skin. There are several types of skin cancer. Skin cancer that forms in melanocytes (skin cells that produce pigment) is called melanoma. Skin cancer that forms in basal cells (small round cells at the base of the outer layer of skin) is called basal cell carcinoma
Ear Cancer
External ear cancer occurs mainly in cases where the outer ear has been exposed for many years to direct sunlight. A small painless ulcer in the first, with an overlying crust, which slowly expands and deepens can be a skin cancer. It is diagnosed by eliminating a small fragment of tissue from the shore and examination under a microscope.
Head and Neck Cancer
The snuff is the most preventable cause of these deaths a lump in the neck cancers that begin in the head or neck usually spread to lymph nodes in the neck before they spread elsewhere. A lump in the neck lasting more than two weeks should be seen by a doctor as soon as possible. Of course, not all tumors are cancerous. But a lump lumps (or) on the neck can be the first sign of cancer of the mouth, throat, larynx (voice box), thyroid gland, or of certain lymphomas or blood cancers. These masses are usually painless and will continue to grow steadily.
