The most common forms of cancer are breast, lung, prostate, colorectal, pancreatic, and stomach cancers. Each form of cancer affects the body differently depending on where it is located and its severity. For example, breast cancer can cause changes in the shape or size of the breasts, while lung cancer can cause shortness of breath and coughing. In addition, some cancers may spread to other parts of the body such as the bones, brain, liver, or kidneys. Cancer treatment varies depending on the type of cancer and its stage. Common treatments include surgery, radiation therapy, chemotherapy, hormone therapy, immunotherapy, and targeted therapy.
