The main reason of cancer is DNA damage (mutation).
Mutations can be subdivided into two main types. The damage is either ‘germline’ or ‘somatic’. While germline mutations are inherited from a parent and occur in the germ cells (8-10% of all cancer types), somatic mutations occur in any of the cells of the body except the germ cells (sperm and egg).
Breast canceris a malignant tumor that starts in the cells of the breast.
A malignant tumor is a group of cancer cells that can grow into (invade) surrounding tissues or spread (metastasize) to distant areas of the body. The disease occurs almost entirely in women, but men can get it, too. 38% of all the cancers in women is breast cancer.
Risk factoris anything that affects the chance of a person to get a disease like cancers.
Whereas some risk factors cannot be changed such as age, gender or race, others are mostly linked to cancer-causing factors in the environment and depend on personal choices like smoking, drinking, malnutrition etc. As the individuals are not aware of their breast cancer risks, they do not take the necessary precautions to avoid from it. However, with an early diagnosis and avoiding the possible risks, 98% of breast tissue can be prevented from cancer. By looking at this information and learning about the risks of breast cancer, individuals with high cancer risk might attend regular screening-tests and learn about their own risks of cancer. So that cancer can be detected in the early stages. Moreover, high-risk patients will be more knowledgeable about risk factors and will avoid those risks. Avoiding the risks will be reduced breast cancer occurrence risk significantly.
