Cancer can grow into, or begin to push on nearby organs, blood vessels, and nerves. This pressure causes some of the signs and symptoms of cancer. Cancer may also cause symptoms like fever, extreme tiredness (fatigue), or weight loss. This may be because cancer cells use up much of the body’s energy supply.
Today I will share with you some of the 5 cancer types that are rated the world’s deadliest from 2021 to 2022. Most notably, doctors can successfully treat cancer if they identify it during the early stages. Most importantly, regular screening and awareness are very important in reducing the chances of dying from cancer.
Furthermore, depending on the type of cancer, these mostly immature cancer cells, will either grow quickly and cause symptoms within a short time or grow slowly over several years. Either way, the results are not good.
One of the most worrying things about cancer is that it is malignant. This means it can easily spread to other parts of the body and destroy them. Therefore, all different types of cancer are a major health risk since they interfere with body functions and destroy body tissues and organs.
Top 5 Deadliest Cancers in the world 2022
1. Lung cancer
According to the World Health Organization (WHO), worldwide, 2.09 million people were diagnosed with lung cancer in 2018. Furthermore, about 1.76 million people died due to lung cancer.
The main cause of lung cancer is cigarette smoking. Even secondhand smoking is dangerous. It is advisable that individuals quit the use of tobacco and other related flavors since it is a health risk to their lives. Inhaling other toxic fumes can also lead to lung cancer.
2. Colon and Rectal Cancer
Again, colon and rectal cancer is another deadly type of tumor. However, it is easily treatable only when identified in stage one. Therefore, it is advisable to regularly undergo screening whenever possible.
3. Breast cancer
First of all, this type of cancer is very common and therefore many of us have heard about it. However, it may lead to an early death if doctors don’t diagnose and treat it early. In contrast, with all the debates and public awareness about breast cancer, the death toll has dramatically increased in 2019.
However, many people who are suffering from this cancer have undergone successful screening from 2019 to 2022 and are undergoing treatment globally.
4. Prostate Cancer
Prostate cancer is cancer that occurs in the prostate. The prostate is a small walnut-shaped gland in males that produces the seminal fluid that nourishes and transports sperm.
Prostate cancer is one of the most common types of cancer. Many prostate cancers grow slowly and are confined to the prostate gland, where they may not cause serious harm. However, while some types of prostate cancer grow slowly and may need minimal or even no treatment, other types are aggressive and can spread quickly.
5. Pancreatic Cancer
It’s number 5 on the list of the deadliest cancers in the world in 2022 today. Pancreatic cancer is cancer that forms in the cells of the pancreas. Cancer begins in the organ lying behind the lower part of the stomach (pancreas). The pancreas secretes enzymes that aid digestion and hormones that help regulate the metabolism of sugars.
This type of cancer is often detected late, spreads rapidly, and has a poor prognosis. There are no symptoms in the early stages. Later stages are associated with symptoms, but these can be non-specific, such as lack of appetite and weight loss. Treatment may include surgically removing the pancreas, radiation, and chemotherapy.
