Cancer treatment is improving, saving lives and extending survival for many people. Depending on various factors, treatment options may include surgery, radiation, immunotherapy, chemotherapy, hormone therapy, or targeted, local therapy, among others. These treatments might be used alone or in combination. Clinical trials evaluate the benefits of new therapies and broaden the options available to patients.

This section includes treatment trends for cancer sites for which there are available data trends and definitive treatment guidelines based on rigorous evidence of benefit to patients, including bladder, breast, colorectal, kidney, lung, ovarian, and prostate cancers.

The American Cancer Society first began conducting long-term prospective studies in the 1950s. The participants provide initial lifestyle, medical, or behavioral information, and then are followed over time to assess their health outcomes to determine how those outcomes are related to the previously collected data. Previous long-term Society studies have played a major role in cancer prevention, including demonstrating the link between cigarette smoking and lung cancer, the impact of being overweight or obese on risk of cancer occurrence and death, and much more.​

(NaturalNews) Cancer is not a disease, but rather a disorder of the cells, where they mutate and multiply uncontrollably. That's why cancer is not contagious, except for HPV, because that's a virus, not a cell disorder.It doesn't matter whether you believe in "conspiracies" or not, because the fact is that American conventional food has been engineered and processed to cause cancer, and in many more ways than one. There is a definitive reason why one out of every three Americans get cancer, when next to nobody in America got cancer 100 years ago

Cancer is the uncontrolled growth of abnormal cells in the body. Cancer develops when the body’s normal control mechanism stops working. Old cells do not die and cells grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor. Some cancers, such as leukemia, do not form tumors.

Cancer is a disease that begins as a renegade human cell over which the body has lost control. In order for the body and its organs to function properly, cell growth needs to be strictly regulated. Cancer cells, however, continue to divide and multiply at their own speed, forming abnormal lumps, or tumors. An estimated 6.7 million people currently die from cancer every year. Not all cancers are natural-born killers. Some tumors are referred to as benign because they don't spread elsewhere in the body. But cells of malignant tumors do invade other tissues and will continue to spread if left untreated, often leading to secondary cancers.   Cancers can start in almost any body cell, due to damage or defects in genes involved in cell division. Mutations build up over time, which is why people tend to develop cancer later in life.

The death rate from cancer in the US has declined steadily over the past 2 decades, according to annual statistics reporting from the American Cancer Society. The cancer death rate for men and women combined fell 25% from its peak in 1991 to 2014, the most recent year for which data are available. This decline translates to more than 2.1 million deaths averted during this time period.
