Cancerdrugs

Typical cancer drugs are chemotherapic agents (cytostatics), which intend to destroy the malignant cells. Cytostatic agents inhibit cell division and thus cause cell death. Cancer medications can be given to reduce or destroy an existing tumor and to counteract a malignant tumor.

How does cancer develop?

Cancer is thought to develop as a consequence of genetic damage in normal cells. The damage can be congenital (10-15 percent of cancer cases) or be caused by, for example, external factors. The cell contains genes which in turn contain germ plasma (DNA) that determines how the cell’s proteins are to be produced. Cancer develops when a string of mutations take place in genes that govern the cell’s ability to grow and divide. These mutations often lead to an overstimulation of cell growth a

What is cancer?

Every human body consists of billions of small cells. These form different tissues and organs such as skin, bone, blood, liver and many more. The cells in these organs have a variety of functions, the skin cells provide protection for the body, the blood cells transport nutrients and oxygen, the muscle cells enable movements and so on.

Radiotherapy

Radiotherapy is usually given to supplement the surgical procedure and to reduce the risk of local spread. In some cancers, radiotherapy without surgery may suffice. Radiation therapy utilizes radioactive radiation that destroys cancer cells and shrinks the tumors by exposing cancer cells to radiation damage. Even healthy tissue is destroyed, but with modern technology healthy tissue can be better saved. Cancer cells tend to divide faster than healthy cells, so they are particularly suscep

Surgical treatment of cancer

One of the most important cancer treatments is that the cancer is surgically removed (surgical treatment). Malignant tumors, such as cancerous growth and sarcoma, are traditionally treated primarily by surgery. This is done to prevent cancer growth. Often, some healthy tissue must also be removed around the cancer. This is done to prevent the spread of the tumor. Nowadays, attempts are made to remove as little healthy tissue as possible. For example, the goal is to operate breast cancer wi
