Cancer prevention. Cancer prevention is the practice of taking active measures to decrease the incidence of cancer and mortality. [1] [2] The practice of prevention is dependent upon both individual efforts to improve lifestyle and seek preventive screening, and socioeconomic or public policy related to cancer prevention. [3]
Shortness of breath, called dyspnea, is a common symptom of cancer and its treatment. The causes of cancer-related dyspnea can include tumors in or around the lung, blocked airways, fluid in the lungs, pneumonia, or treatment reactions including an allergic response.
Cancer is caused by genetic changes leading to uncontrolled cell growth and tumor formation. The basic cause of sporadic (non-familial) cancers is DNA damage and genomic instability. [1] [2] A minority of cancers are due to inherited genetic mutations. [3] Most cancers are related to environmental, lifestyle, or behavioral exposures. [4]
According to the Centers for Disease Control and Prevention, it is the second leading cause of death for Americans, and projections from the American Cancer Society show there will be more than 2 ...
Scientist Otto Warburg, whose research activities led to the formulation of the Warburg hypothesis for explaining the root cause of cancer.. The Warburg hypothesis (/ ˈ v ɑːr b ʊər ɡ /), sometimes known as the Warburg theory of cancer, postulates that the driver of tumorigenesis is an insufficient cellular respiration caused by insult to mitochondria.

Diet and obesity may be related to up to 30–35% of cancer deaths, [1] while physical inactivity appears to be related to 7% risk of cancer occurrence. [2] While many dietary recommendations have been proposed to reduce the risk of cancer, few have significant supporting scientific evidence. [3] [4] [5] Obesity and drinking alcohol have been ...
Lung cancer. Lung cancer, also known as lung carcinoma, is a malignant tumor that begins in the lung. Lung cancer is caused by genetic damage to the DNA of cells in the airways, often caused by cigarette smoking or inhaling damaging chemicals. Damaged airway cells gain the ability to multiply unchecked, causing the growth of a tumor.
