Myths about cancer: What is really true?
Whether it is on social media, among friends or even in some media reports – false information can quickly cause uncertainty. Here is the correct information on the subject of cancer.
Cancer is one of the most common diseases in Switzerland, but many myths and misunderstandings surround it. In this article, we shed light on the most common cancer myths and explain what science says about them.
Myth 1: ‘Cancer is always hereditary’
Many people believe that cancer is mainly caused by genetic factors. However, the truth is that only about 5-10% of all cancers are due to inherited genetic mutations. Most cancers arise from a combination of lifestyle factors and environmental conditions.
Myth 2: ‘Sugar promotes tumour growth’
It is true that tumour cells need sugar (glucose) to grow, but so do all other cells in the body. There is no scientific evidence that consuming sugar directly promotes the growth of tumours. A balanced diet is important, but cutting sugar out of your diet completely has no demonstrable benefits for cancer patients.
Myth 3: ‘Cancer is always fatal’
Thanks to medical advances, survival rates for many types of cancer have improved significantly in recent decades. Early detection and modern therapies such as immune or targeted therapies significantly increase the chances of recovery. Many types of cancer that were once considered incurable can now be treated successfully.
Myth 4: ‘Mobile phone radiation causes cancer’
There is widespread fear that mobile phone radiation causes cancer. However, scientific studies have not shown any clear link between the use of mobile phones and an increased risk of cancer. The radiation from mobile phones is non-ionising, which means that it cannot damage the genetic material of the cells.
Myth 5: ‘A positive attitude can cure cancer’ It is important to stay optimistic, but a positive attitude alone cannot cure cancer. While faith and confidence can support the healing process and improve quality of life, they should not be considered a substitute for medical treatment.
