It is said that cancer, i.e. a malignant tumor, is a civilization disease. It is in vain to look for people who have never encountered this disease – both among family members and friends. However, few people know what cancer really is. Find out how a malignant tumor develops. Is every tumor cancer?

The word “cancer” evokes great emotions and triggers a feeling of fear. However, it is not a small crustacean, but a malignant tumor that remained an incurable disease until the 20th century. Nowadays, medicine is better and better at treating malignant neoplasms, although the full cure of cancer is still a challenge for modern oncology.

Where does the name cancer come from? This term dates back to antiquity when crab-shaped malignant breast tumors in women were termed cancer. In medieval records, however, the term “cancer” is used to describe all malignant tumors found in different parts of the body.

Is every tumor cancer?

Cancer and cancer are terms that are often used interchangeably. However, not all cancers are cancer, just not everyone is malignant and not everyone should be feared at once. While not all neoplasms are malignant, all types of cancer are malignant.

What distinguishes cancer from a benign tumor is the ability of cells to continue growing and spreading unchecked throughout the body. Cancer cells are destructive.


  • Benign tumor (benign): grows locally and does not metastasize. It is usually more common than malignant, but it is not a major oncological problem. A benign tumor is usually just cut or observed. However, in some cases, a benign (non-malignant) tumor is treated as a condition preceding the development of a malignant tumor (for example, polyps of the large intestine).
  • Malignant neoplasm (cancer): cancer cells tend to spread, so the primary tumor grows, but disease outbreaks also form elsewhere in the body (metastasis). Abnormal cells are designed to destroy the body, and are also sometimes resistant to treatment. An early stage tumor can usually be excised, but advanced cancer is usually treated with radiation and chemotherapy.
