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. The goal of cancer treatment is to cure the patient and keep the cancer in control. Relapse of the cancer and its spread is prevented. The symptoms caused by the tumor are alleviated. Modern cancer treat...

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 a...

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 su...

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 cance...

Irish researcher Arvind Negi (National University of Galway) asked on the science channel ResearchGate (https://www.researchgate.net/ ) why a cancer cell both develops its own acidity and thrives in an acidic environment. He sparked quite a lively discussion. Here is a summary of the discussion....
