Cancer is the name for malignant tumours that arise from uncontrolled replication of malignant cells. Cancer cells demonstrate an uncontrolled and destructive growth and form growths called tumours. Cancer is a collective term for various types of malignant cell growths that can occur in all areas of the body. The term “cancer” dates back to Hippocrates; he compared the ever-expanding growths to the claws of a crab.
The field of oncology deals with the prevention, diagnosis, and treatment of cancer. Over the last two decades, enormous progress has been made; many patients with malignant diseases can now be cured.
Despite the therapeutic successes oncological diseases are among the most common causes of death (after cardiovascular diseases). There are forms of the disease for which no cure has been found.
When blood cells do not develop properly
As a result of certain genetic changes, every cell in the body can degenerate, which leads to uncontrolled growth and the formation of tumours. Tumours of the lymphatic system are called lymphomas. In the later stage of the disease, approx. 10% of lymphoma patients contract lymphomatous meningitis – the spread of tumour cells into the central nervous system and ultimately the meninges.
