The following is a list of cancer types. Cancer is a group of diseases that involve abnormal increases in the number of cells, with the potential to invade or spread to other parts of the body. [1] Not all tumors or lumps are cancerous; benign tumors are not classified as being cancer because they do not spread to other parts of the body. [1]
Ionizing radiation may be used to treat other cancers, but this may, in some cases, induce a second form of cancer. [74] Radiation can cause cancer in most parts of the body, in all animals, and at any age, although radiation-induced solid tumors usually take 10–15 years, and can take up to 40 years, to become clinically manifest, and ...
The most common as of 2018 are lung cancer (1.76 million deaths), colorectal cancer (860,000) stomach cancer (780,000), liver cancer (780,000), and breast cancer (620,000). [2] This makes invasive cancer the leading cause of death in the developed world and the second leading in the developing world . [ 25 ]
Although new cases of cancer may have climbed by roughly 24 percent in men and 21 percent in women, according to the Centers for Disease Control and Prevention, doctors and researchers are making ...
Worldwide in 2015, the most common causes of cancer death were lung cancer (1.6 million deaths), liver cancer (745,000 deaths), and stomach cancer (723,000 deaths). [7] Lung cancer is largely due to non-infectious causes, such as tobacco smoke. However, liver and stomach cancer are primarily due to infectious causes.
The second highest cause of death was cardiovascular diseases, resulting in 21.5% of deaths. In 2011, prostate cancer was the most common form of cancer among males (about 28% of all new cases) and breast cancer the most common in females (also about 28% of all new cases). [citation needed]
Colorectal cancer rates in people under 55 are increasing and it's more advanced. Experts are unsure why, but think diet, exercise and environment play a role.
Cancer diagnoses in adults under 50, while increasing, are still rare, and U.S. cancer deaths have been declining thanks to fewer people smoking tobacco and better treatment.
