Rare deadly diseases list
There are many diseases that are dangerous to mankind. Whether they are incurable, chronically lethal or acutely deadly, certain illnesses have dire affects when humans are infected. Viruses, bacteria, genetic abnormalities or even simple proteins can be the cause of the most dangerous diseases. No matter the cause, these serious diseases can threaten the lives and well-being of those afflicted.
The most dangerous type of cancer is lung cancer. Lung cancer kills more men and women in a year than breast, colon, and prostate cancers combined, according to MedlinePlus, a National Institutes of Health website. Lung cancer is rare in adults younger than 45, but 60 percent of patients who develop the cancer die within one year of diagnosis. The cancer begins in the lungs and can be composed of either non-small cells or small cells. Non-small cell cancer is the most common cancer, while small cell cancer composes 20 percent of all cases of lung cancer.
The most common cause of cancer is smoking. The more frequent a person smokes the higher the risk of developing cancer. Non-smokers, however, can also be affected. Approximately 3, 000 non-smokers will develop lung cancer due to exposure to secondhand smoke. Early diagnosis can allow for more timely treatment and removal of the tumor, but if the cancer has already spread to other organs or is in an advanced stage, the patient will most likely not survive.
