Oral cavity cancer, or just oral cancer, is cancer that starts in the mouth (also called the oral cavity). Mouth cancer is a cancer that can develop in any part of the mouth, including the tongue, the gums, the palate (roof of the mouth), under the tongue, the skin lining the mouth or the lips.It is twice as common in men as it is in women . Some people develop mouth cancer for no apparent reason. However, certain risk factors increase the chance of developing cancer in mouth . These include:
Smoking. Mouth cancer is just one cancer which has a much higher incidence in smokers than in non-smokers.
Alcohol. Drinking a lot of alcohol can increase your risk of developing mouth cancer.
Chewing tobacco or the betal leaf.
The human papillomavirus (HPV) may increase your risk of mouth cancer.
There are some conditions affecting the mouth, such as leukoplakia and erythroplakia.
which can increase the risk of a cancer development.
Mouth cancer is not hereditary, so does not run in families.
Breast cancer is a malignant tumor that starts in the cells of the breast. A malignant tumor is a group of cancer cells that can grow into (invade) surrounding tissues or spread (metastasize) to distant areas of the body. The disease occurs almost entirely in women, but men can get it, too.Basically breast cancer in majorly is divided in 2 parts:-
Blood cancers affect the production and function of your blood cells. Most of these cancers start in your bone marrow where blood is produced. Stem cells in your bone marrow mature and develop into three types of blood cells: red blood cells, white blood cells, or platelets. In most blood cancers, the normal blood cell development process is interrupted by uncontrolled growth of an abnormal type of blood cell. These abnormal blood cells, or cancerous cells, prevent your blood from performing many of its functions, like fighting off infections or preventing serious bleeding.
Pancreatic cancer often goes undetected until it’s advanced and hence it is difficult to treat. In the vast majority of cases, symptoms only develop after pancreatic cancer has grown and begun to spread. Initially, pancreatic cancer tends to be silent and painless. By the time it’s large enough to cause symptoms, pancreatic cancer has generally grown outside the pancreas.
When you have leukemia, the bone marrow starts to make a lot of abnormal white blood cells, called leukemia cells. They don’t do the work of normal white blood cells. They grow faster than normal cells, and they don’t stop growing when they should. Over time, leukemia cells can crowd out the normal blood cells. This can lead to serious problems such as anemia, bleeding, and infections. Leukemia cells can also spread to the lymph nodes or other organs and cause swelling or pain.
The liver continuously filters blood that circulates through the body, converting nutrients and drugs absorbed from the digestive tract into ready-to-use chemicals. The liver performs many other important functions, such as removing toxins and other chemical waste products from the blood and readying them for excretion. Because all the blood in the body must pass through it, the liver is unusually accessible to cancer cells traveling in the bloodstream.
Stomach cancer also called gastric cancer, is a malignant tumor arising from the lining of the stomach. Stomach cancers are classified according to the type of tissue where they originate. The most common type of stomach cancer is adenocarcinoma, which starts in the glandular tissue of the stomach and accounts for 90% to 95% of all stomach cancers. Other forms of stomach cancer include lymphomas, which involve the lymphatic system and sarcomas, which involve the connective tissue.
