According to the Centers for Disease Control and Prevention, cancer is the No. 2 cause of death in America, second only to heart disease. While better screening methods and treatments are saving lives, some types of cancer remain terribly deadly. Here's a look at the 10 lethal cancers that you should watch out for.
1. Lung and bronchus cancer
According to the American Cancer Society, lung cancer is by far the leading cause of cancer death in both men and women. The most deadly cancer in the United States, lung and bronchus cancer is most critical when the affected cells within the lungs spread to other organs. Obviously, cigarette smoking and use of tobacco products are two of the major causes and are responsible for 90% of diagnoses, but even if you don't smoke, you are still at risk.
2. Colorectal cancer
Colorectal cancer occurs when benign cells called polyps form in the colon. According to the Centers for Disease Control and Prevention, it's a possibility that the polyps can become cancerous. Fortunately, colorectal cancer is preventable. People over 50 should do regular colon screenings because the doctor can remove the polyps before it's too late. Remember to eat fruits and vegetables to minimize the odds of developing colorectal cancer.
3. Pancreatic cancer
The Pancreas plays a vital role in your body, aiding digestion and metabolism. Detection and early intervention when confronted by pancreatic cancer are both difficult, because it develops very fast. When you notice the symptoms, including digestive problems, jaundice, abdominal pain and so on, pancreatic cancer has reached the later stages. Risk factors include being diabetic, liver damage, smoking cigarettes and unhealthy lifestyle.
4. Breast cancer
As the second most common cancer amongst women in the US, breast cancer occurs when cells in the breast mutate and result in a malignant tumor. Usually, the cancer forms in the glands that produce the milk or the ducts that carry milk to the nipple. Risk factors include family history, giving birth to your first child later in life, never giving birth, menstruating before age 12, and going through menopause after the age of 55.
5. Liver and intrahepatic bile duct cancer
The liver is one of the most crucial organs in your body. It processes the food you eat and fluid you drink as well as removing toxins from your blood. A closely-related cancer to liver cancer is intrahepatic bile duct cancer, which occurs in the duct that brings bile from the liver to the small intestine. Hepatitis B and C infections are dangerous for you as well, because they can lead to cirrhosis.
6. Prostate cancer
According to the Urology Care Foundation's report, prostate cancer is the third-leading cause of cancer death for men in the United States. Similar to the cancers mentioned above, prostate cancer has no symptoms in its early stages. When you notice the symptoms such as an enlarged prostate, it is more likely to be terminal. Sometimes the malignant growths can be removed, but they may grow back.
Generally speaking, leukemia affects the blood-forming tissues of the body, causing the bone marrow to produce abnormal white blood cells. Different types of leukemia have different symptoms. Cold and flu-like symptoms are common, while some other types don't have any obvious symptom and live inside the human body for years.
8. Non-Hodgkin lymphoma
Blood cancers that develop in the lymph nodes or lymphatic tissue are called non-Hodgkin lymphoma. This type of cancer occurs when white blood cells mutate and begin to grow and produce more abnormal cells that go on to form tumors. The symptoms include larger lymph nodes, fever and weight loss.
9. Bladder cancer
Most of the time, bladder cancer can be diagnosed early and treated, but it's still dangerous. The most common symptom is blood in the urine. People who smoke cigarettes, are prone to bladder infections or have a family history are more likely to develop bladder cancer.
10. Brain and nervous system cancer
Last but not the least, brain cancer may not be as deadly as the cancers above, but you shouldn't ignore the symptoms. The symptoms are numerous, including headaches, muscle weakness, and clumsiness, and so on. As you can see, they are so general that it's easy to neglect them. Therefore, go to see a doctor as soon as you feel sick.
