Overview
Cancer is a class of diseases in which cells divide without control or order. The over-division of cells results in a structure known as a tumor. Not all tumors are cancerous. In order to be classified as a Cancer, a tumor must destroy adjacent tissues.
Non-cancerous (benign) tumors do not invade into surrounding tissues, and they do not spread to other parts of the body (metastasis).
There are more than 200 different types of cancer, each with a unique variety of signs and symptoms, diagnostic and staging features, and treatment options.
Types of Cancer
Most cancer types are subcategorized into a variety of oncology classifications.

Cancer Symptoms
Cancer patients experience a wide variety of symptoms. Each of cancer's symptoms depend on the type and stage of the malignancy (cancerous growth), and the patient’s overall health. Some cancers produce no specific symptoms, underlining the importance of regular cancer screenings, as well as risk factor minimization.

Cancer Stages
Cancer staging is determined by the size, location, and behavior of a cancer. A cancer's "stage" is a descriptor, or identity (usually a Roman Numeral between I and IV) that influences the treatment and outlook (prognosis) of the cancer.
- Treatment: The various stages of cancer require unique treatment strategies. Treating late-stage cancers, for example, may involve a variety of therapies and treatment modalities aimed at reducing the cancer’s symptoms. Treating early-stage cancers, on the other hand, may involve a simple curative procedure.
- Outlook: Understanding the severity of a cancer helps physicians and their patients plan for the future.

Cancer Treatment and Therapy
Cancer treatment differs depending on the unique characteristics of each cancer and patient. The appropriate treatment strategy relies on a number of factors, including the type, size, and location of the cancer, as well as the patient’s medical history and overall health.
There are several standard treatment modalities available for cancer, such as chemotherapy, surgery, and radiation therapy. These treatment modalities are designed to complement an array of cancers and physical scenarios. Many cancer patients also incorporate alternative therapies into their cancer treatment plan. Talk to your doctor about the best treatment strategy for you.
