Cancer is a broad term that describes a group of diseases characterized by the uncontrolled growth of abnormal cells. There are over 200 different types of cancer, each with its own characteristics and treatment options. Some cancers can be treated successfully while others may require more aggressive treatments such as chemotherapy or radiation therapy. The type of cancer you have will determine the prognosis, which is your chance of recovery.
