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 without having to remove the entire chest. However, if the cancer has spread too far, it is not possible to go on with such a conservative surgery. Sometimes the surrounding tissues must be completely removed. Sometimes entire internal organs are also removed (radical surgery). In radical surgery all detectable tumors and a portion of the surrounding healthy tissue is removed. Radical surgery aims to completely eliminate the cancer. If the area is large which remains when the tumor is removed, it is possible to fill up with adjacent tissue. Often the lymph nodes and vessels are removed from the cancer and if necessary removed also near the cancer growth.

A successful cancer operation is characterized by knowledge of the type of cancer, its spread and its location in the body. When the surgery is done at an early stage, the cancer's prognosis is quite good.

The cancer surgery can be the only treatment you get, but often radiotherapy is given and drug treatments are also started. Such combinational therapy is necessary because cancer cells can begin to spread to other parts of the body at a very early stage, and this cannot be prevented by surgery.

Sometimes the tumors are in such troublesome places that they cannot be operated completely or even partially. Some cancers cannot be operated at all, such as eg. cancer of the blood system (leukemia) that does not at all form solid tumors.

Cancer symptoms can be alleviated by surgery. An example of a relief operation is to open a clogged bile duct or an intestinal obstruction in patients with cancer of the pancreas.

With metastasis operations, certain metastases can be removed, for example, from the liver, lungs or bone. Often there are so many metastases or they are in such difficult places that the surgeon is forced to give up.

Nowadays, with various operations, one can prevent certain cancers or remove precursors to cancer. Preventive surgery can be used to treat bowel cancer precursors. For example, the person carrying the so-called breast cancer gene can completely remove her breasts.

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.

Traditional cancer treatment

Cancer is the subject of intensive research and new therapies are constantly evolving. In this section, we focus on the traditional ways of treating cancer. If you are interested in complementary and integrative cancer treatments, you can find this information elsewhere on our website.

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
