Top 3 Deadliest Cancers
Cancer is a leading cause of death worldwide and there are many types of cancer, each of which can differ in severity and prognosis. The three deadliest cancers are lung cancer, liver cancer and colorectal cancer.
Lung Cancer
Lung cancer is the leading cause of cancer-related deaths worldwide. The primary risk factor for developing lung cancer is smoking, but other factors such as exposure to second-hand smoke, air pollution, and occupational hazards may also increase the risk. Symptoms of lung cancer may include a persistent cough, coughing up blood, chest pain, and shortness of breath. Treatment options may include chemotherapy, radiation, surgery, and targeted therapy.
Liver Cancer
Liver cancer is the second leading cause of cancer-related deaths worldwide. Risk factors for developing liver cancer include chronic hepatitis B and C infections, alcohol use, and a family history of the disease. Symptoms may include abdominal pain, jaundice, fatigue, appetite loss, and weight loss. Treatment options may include surgery, chemotherapy, and radiation therapy.
Colorectal Cancer
Colorectal cancer is the third leading cause of cancer-related deaths worldwide. Risk factors for colorectal cancer include age, obesity, a family history of the disease, and a diet high in red and processed meats. Symptoms may include rectal bleeding, changes in bowel habits, abdominal pain, and fatigue. Treatment options may include surgery, chemotherapy, radiation therapy, and targeted therapy.
