Head & Neck Cancer

Cancers that are known collectively as head and neck cancers usually begin in the squamous cells that line the moist, mucosal surfaces inside the head and neck (for example, inside the mouth, the nose, and the throat).
These squamous cell cancers are often referred to as squamous cell carcinomas of the head and neck. Head and neck cancers can also begin in the salivary glands, but salivary gland cancers are relatively uncommon.
Salivary glands contain many different types of cells that can become cancerous, so there are many different types of salivary gland cancer.
Cancers of the head and neck are further categorized by the area of the head or neck in which they begin. These areas are described

Throat Cancer

Cancer is a class of diseases in which abnormal cells multiply and divide uncontrollably in the body. These abnormal cells form malignant growths called tumors. Throat cancer refers to cancer of the voice box, the vocal cords, and other parts of the throat, such as the tonsils and oropharynx.

Throat cancer is often grouped into two categories: pharyngeal cancer and laryngeal cancer. Pharyngeal cancer forms in the pharynx. This is the hollow tube that runs from behind your nose to the top of your windpipe. Laryngeal cancer forms in the larynx, which is your voice box.

Liver Cancer

Primary liver cancer is a condition that happens when normal cells in the liver become abnormal in appearance and behavior. The cancer cells can then become destructive to adjacent normal tissues, and can spread both to other areas of the liver and to organs outside the liver.

Malignant or cancerous cells that develop in the normal cells of the liver (hepatocytes) are called hepatocellular carcinoma. A cancer that arises in the ducts of the liver is called cholangiocarcinoma.

Ovary Cancer

Ovarian cancer is a malignant tumour in one or both ovaries. Some cases of ovarian cancer can form in the fallopian tube and spread to the ovary.

TYPE OF THE OVARY CANCER

Epithelial ovarian cancers: The majority of women with ovarian cancer have cancer that starts in the surface of the ovary (epithelium). Types of epithelial ovarian cancer include serous, clear cell, endometrioid and mucinous cancers. Germ cell ovarian cancers: About 4% of women have these rare types of cancer, which start in the egg-producing cells. Germ cell cancers usually affect women aged around 35.

Lung Cancer

Lung cancer starts in the cells of the lung. A cancerous (malignant) tumour is a group of cancer cells that can grow into and destroy nearby tissue.

It can also spread (metastasize) to other parts of the body. When cancer starts in lung cells, it is called primary lung cancer.
The lung is part of the respiratory system. You use your lungs when you breathe. The lungs are in the chest, one on each side of the heart. The right lung has 3 main parts, called lobes.
