The most killer cancer is a difficult question to answer, as no single type of cancer is more destructive than any other. Instead, it is often more accurate to talk about the most common types of cancer, or the most deadly cancers.
When it comes to the most common types of cancer, the most frequently diagnosed cancers worldwide are lung, breast, and colorectal cancers. Lung cancer is the most common type of cancer in both men and women, accounting for around 13 percent of all new cancer cases. Breast cancer is the most common cancer among women, making up around 11 percent of all new cancer cases. Colorectal cancer is the third most common cancer worldwide, making up around 8 percent of all new cancer cases.
The most deadly cancers are those that are most difficult to treat successfully. Cancers of the pancreas, liver, and esophagus are some of the deadliest cancers, as they often have poor survival rates. Pancreatic cancer is particularly deadly, with a five-year survival rate of just 9 percent. Other deadly cancers include brain, stomach, and gallbladder cancers.
Overall, no single type of cancer can be labeled as the most killer cancer. However, it is important to be aware of the most common and most deadly types of cancer, and to take the necessary steps to prevent them.
