What are some examples of incurable cancers

Definition Cancer or cancerous tumor is the collective name for a malignant tumor that forms as a result of uncontrolled cell growth and destroys adjacent healthy tissue. Another name is malignancy. At the same time, the term cancer is used to describe the clinical picture. The medical specialty that deals with the research and therapy of cancer diseases is called oncology.

In Germany, cancer is the second most common cause of death after cardiovascular diseases. Women mainly develop breast cancer, colon cancer and uterine cancer, while lung, colon and prostate cancer are most common in men. Around 100 different types of cancer are currently known.

Cancer cells arise through changes in the genes in a body cell and are therefore also referred to as degenerate. Since the naturally predetermined sequence of cell division and cell death is disturbed, they can multiply unchecked. A tumor forms. Via the blood vessels and the lymphatic system, the cancer cells form daughter tumors, so-called metastases, throughout the body. More than 90% of all cancer patients die from these metastases, not the original tumor.

Cancer can affect any type of tissue. Carcinoma is a malignant tumor that develops from skin, mucous membrane or gland cells. Most cancers are carcinomas. Sarcomas that develop from connective tissue cells are less common. The different types of cancer are named after their location or the organ on which the tumor forms, for example breast or skin cancer. Blood cancer is the slang term for the degeneration of white blood cells, also known as leukemia.

The diagnosis of cancer is usually made by examining the affected tissue in the laboratory. Depending on the type of cancer and stage of the disease, the following methods of treatment are possible:

A combination of several forms of therapy is often useful, among other things to keep side effects to a minimum. Treatment goals are to remove the tumor, prevent or destroy the cancer cells from growing, and prevent relapse. In addition, it is important to maintain or improve the patient's quality of life. The average cure rate for all cancers is just under 40%. A period of several years, within which no more cancer cells can be detected, is decisive for healing. This period of time varies depending on the type of cancer and is based on empirical values.

For many types of cancer, early detection is extremely important as it greatly improves the chances of recovery. Most cancers, once advanced to an advanced stage, are incurable.

The following symptoms can indicate cancer:

The prevention includes the annual check-ups, which are financed by the health insurance for women from the age of 30 and for men from the age of 45. Risk factors that increase the chances of getting cancer include:

  • Smoke,
  • Inhalation of so-called fine dust, for example car exhaust, and contact with certain chemicals such as benzene. Some substances, such as asbestos, are carcinogens, i.e. substances that cause cancer. If a working person who has to deal with these substances falls ill with cancer, his illness is recognized as an occupational disease;
  • Radiation exposure to ultraviolet light, which also includes sun rays, X-rays and gamma rays,
  • one-sided and low-vitamin diet, grilled and smoked foods,
  • Stress.

Cancer diseases increase with age, so cancer can also be described as an age-related breakdown process of cell growth.
