Cancer is a life-threatening disease that affects millions of people around the world. It is the second leading cause of death globally, accounting for about 9.6 million deaths in 2018.

Cancer cells can develop in any part of the body and can spread to other organs or tissues, making it a complex disease to treat. However, there are ways to minimize the risk of developing cancer and to improve the chances of survival if you are diagnosed. Here are the top 7 cancer killers:.

1. Lung Cancer

Lung cancer is the number one cancer killer worldwide, accounting for more deaths than any other cancer. The risk of developing lung cancer increases with age and is closely related to tobacco use.

Smoking is responsible for about 85% of all cases of lung cancer. Other factors that increase the risk of developing lung cancer include exposure to secondhand smoke, air pollution, and certain chemicals such as asbestos and radon.

2. Breast Cancer

Breast cancer is the most common cancer among women worldwide. It is also a leading cause of cancer deaths in women. Early detection through regular screening can significantly improve the chances of survival.

Women who have a family history of breast cancer are at a higher risk of developing the disease. Other risk factors include hormone therapy, obesity, and alcohol consumption.

3. Colorectal Cancer

Colorectal cancer is the third most common cancer globally, but it is also one of the most preventable. Screening tests such as colonoscopies can detect precancerous polyps and early-stage cancer, which can improve the chances of successful treatment.

The risk of developing colorectal cancer increases with age, and other risk factors include a family history of the disease, a diet high in red and processed meats, and a sedentary lifestyle.

4. Pancreatic Cancer

Pancreatic cancer is a highly deadly cancer that often goes undetected until it has spread to other organs. It is difficult to treat because it is often diagnosed at an advanced stage.

6. Liver Cancer

Liver cancer is a leading cause of cancer deaths globally. The risk of developing liver cancer is closely linked to hepatitis B and C infections, which can cause chronic liver disease and cirrhosis.

Other risk factors include alcohol abuse and exposure to certain chemicals such as aflatoxins, which are produced by certain molds that grow in food.

7. Stomach Cancer

Stomach cancer is a relatively uncommon cancer but is still a leading cause of cancer deaths worldwide.

The risk of developing stomach cancer is higher in people who have a family history of the disease, those who have had a previous stomach surgery, and those who have a certain type of stomach inflammation called gastritis. Other risk factors include smoking, a diet high in salted or smoked foods, and exposure to certain chemicals such as nitrites and nitrates.

While these cancers are considered the top killers, there are also many other types of cancer that can be deadly.

The key to preventing cancer is to lead a healthy lifestyle, avoid tobacco and alcohol, get regular exercise, maintain a healthy weight, and get recommended cancer screenings at the appropriate ages.
