Cancer is the name given to a collection of related disease in which cells begin to grow out of control. It can develop almost anywhere in the body. There are over 200 different types of cancer and here are the five deadliest ones.
1. Pancreatic cancer
Pancreatic cancer is one of the deadliest. It is an aggressive form of cancer that develops in the tissues of the pancreas. It contains both exocrine glands and endocrine glands responsible for the production of enzymes that help the body to digest the food and hormones that help to control blood sugar levels in the body. Located deep in the back of the abdomen, too often, by the time the tumor is located, the cancer has spread beyond the initial state, making it more difficult to treat. Warning Signs include abdominal pain, digestive problems and Jaundice.
2. Liver and intrahepatic bile duct
Liver cancer begins in the tissues of the liver, an organ that sits in the upper right portion of the abdomen, beneath the diaphragm and below the stomach. It is rated as one of the scariest cancers, with a dismal five-year patient survival rate of only 10%. Several types of cancer can be formed in the liver. The most common type of liver cancer is hepatocellular carcinoma, which begins in the main type of liver cell (hepatocyte).
There are certain other types of liver cancer, such as hepatoblastoma and intrahepatic cholangiocarcinoma which are less common. Warning Signs include fatigue, loss of appetite, vomiting and unintended weight loss.
3. Lung cancer
This is the number one cause of cancer deaths in both males and females worldwide. Smoking cigarette is the main cause for the development of lung cancer. The length of time and the number of cigarettes you’ve smoked, increases the risk of lung cancer. If you quit smoking, even after smoking for many years, you can significantly reduce your chances of developing lung cancer. The two types of lung cancer, which grow and spread differently, are small cell lung cancers (SCLC) and non-small cell lung cancers (NSCLC).
4. Esophageal cancer
Esophageal cancer is a tumor that begins to grow in the lining of the esophagus, and then can grow through the wall of the esophagus. The tumor can spread to other parts of the body through the lymphatic system if it grows through the esophageal wall. A lump in your throat that doesn’t go away could be a sign of esophageal cancer. Depending on its location, you may not even feel it, so it’s important to also look for other symptoms. Warning signs include heartburn, difficulty in swallowing, pneumonia and chest pain.
5. Brain cancer
The brain and spinal cord make up the central nervous system. Brain and spinal cord tumors are the growth of abnormal cells in tissues of the brain or spinal cord. Tumors that start in the brain are called primary brain tumors. A tumor that starts in another part of the body and spreads to the brain is called a metastatic brain tumor. The signs and symptoms of brain and spinal cord tumors depend on the size of the tumor, where it is formed, how fast it is growing and the age of the patient. Brain cancer can occur in both adults and children.
