These are the 6 most aggressive types of cancer that exist; Know the symptoms of each

0

A recent study carried out by the Global Cancer Observatory and the International Agency for Research on Cancer (IARC), both entities associated with the World Health Organization (WHO), revealed the most aggressive types of cancer, with high mortality rates.

Among the most lethal, cancers of the pancreas, gallbladder, esophagus, liver, lung and brain stand out. These types of cancer have an unfavorable prognosis, especially due to the difficulty in early diagnosis and the silent evolution of the diseases.

The importance of early diagnosis

Detecting cancer early is essential for successful treatment. The earlier the disease is identified, the greater the chances of effective intervention. Experts recommend that people be aware of any changes in their body and seek medical attention quickly. The study highlights that, often, the symptoms of the most dangerous types of cancer may not be noticed until the disease is at an advanced stage.

• Weakness

• Back pain
  

  2. Gallbladder Cancer
