Cancer Treatment
Cancer Treatment is the use of surgery, radiation, medications and other therapies to cure a cancer, shrink a cancer or stop the progression. It  is a class of diseases characterized by out-of-control cell growth. There are over 100 different types of cancer, and each is classified by the type of cell that is initially affected.
Cancer harms the body when damaged cells divide uncontrollably to form lumps or masses of tissue called tumors (except in the case of leukemia where cancer prohibits normal blood function by abnormal cell division in the bloodstream). Tumors can grow and interfere with the digestive, nervous, and circulatory systems, and they can release hormones that alter body function.
More dangerous, or malignant, tumors form when two things occur:
a cancerous cell manages to move throughout the body using the blood or lymph systems, destroying healthy tissue in a process called the invasion
that cell manages to divide and grow, making new blood vessels to feed itself in a process called angiogenesis.
What are the symptoms of cancer?
Cancer symptoms are quite varied and depend on where the cancer is located, where it has spread, and how big the tumor is. Some oral cancers present white patches inside the mouth or white spots on the tongue.
Other cancers have symptoms that are less physically apparent. Some brain tumors tend to present symptoms early in the disease as they affect important cognitive functions. Pancreas cancers are usually too small to cause symptoms until they cause pain by pushing against nearby nerves or interfere with the liver function to cause a yellowing of the skin and eyes called jaundice.. For example, colon cancers lead to symptoms such as constipation, diarrhea, and changes in stool size. Bladder or prostate cancers cause changes in bladder function such as more frequent or infrequent urination.
As cancer cells use the body’s energy and interfere with normal hormone function, it is possible to present symptoms such as fever, fatigue, excessive sweating, anemia, and unexplained weight loss. However, these symptoms are common in several other maladies as well. For example, coughing and hoarseness can point to lung or throat cancer as well as several other conditions.
